Version 1.5 - 05/18/98
Use with EAS1 V5.9 and above EPROM
1 Introduction -
The EAS Setup Program, EASETUP.EXE, is designed to run on any IBM PC or clone with using either serial port COM1 or COM2. The program runs as a DOS application on a PC using any version of DOS from 3.1 and up, or in Windows or Windows95 in DOS mode.
A serial cable with a male DB9 on one end and female DB9 on the other end may be used to connect the male DB9 on the PC port to the female DB9 on the encoder/decoder computer port. When the encoder/decoder detects the proper code sequences from the PC, it will receive a packet of setup information from the PC and store it in non-volatile memory. The setup program allows the operator to select the desired setup information from menus before downloading it to the encoder decoder.
To operate properly, the setup program requires the transmitted data to be echoed
back by the encoder/decoder. However the program can be used without connection to
the encoder/decoder, if a loopback connector is connected to the PC COM port.
Loopback connectors can be purchased from PC supply stores, loopback connectors are often
supplied with PC diagnostic programs such as Norton Utilities, or they may be fabricated
from a female DB9 connector by connecting the following conductors together:
1-4-6-9, 2-3, 7-8. Pin 5 is not connected.
When requested by the customer, this program will be used by Gorman-Redlich to
set up an encoder decoder with the information supplied by the customer on the order
form. In this case, the unit is ready for operation when received by the
customer. The setup information is supplied to the customer on a floppy disk so that
the program may be used later by the customer to change or update the setup information.
2 Installation -
The EASETUP program is written to run as a DOS application so that it will be compatible with as many PC type computers as possible. On newer Windows based systems, simply go to the DOS prompt and continue with these instructions as though it were a DOS system. The program and associated files are distributed on a high density 3.5" floppy diskette, but may be ordered on other types of diskettes such as a 5.25" diskette, if desired. It may be transferred from one type of diskette to another by the user by simply using the DOS COPY command.
The simplest, although probably not the best, form of operation is to run the program directly from the floppy disk. In this case, insert the diskette into floppy drive A: or B:. Before running directly from the diskette, make a backup copy of the distribution diskette using the DOS copy command. At the DOS prompt, type A: or B: to correspond to the floppy drive containing the diskette. The DOS prompt will then show A:> or B:> corresponding to your selection. At that point type EASETUP and <ENTER> (press the ENTER key), and the program will start (the program name is EASETUP.EXE).
This form of operation is the only option for older computers with no hard drive. If a hard drive is available, much faster operation can be obtained by installing the program on the hard drive. Another advantage is that the data on the floppy drive is protected from unintended change when working from the hard drive. The installation is very simple. At the DOS prompt for the hard drive (usually C:>), make a directory for the program and associated files. If the directory name is to be EAS1, the following command: "MD EAS1 <ENTER>" (<ENTER> means to just press the ENTER key) will make the directory. The command "CD EAS1 <ENTER>" (or whatever name was used) will select the new directory. The command "COPY A:*.* <ENTER>" or "COPY B:*.* <ENTER>" (depending on whether the diskette is in floppy drive A: or B:) will copy the contents of the diskette to the hard drive. The copy is the extent of the hard drive installation. The program may be executed at any time by going to the directory ("CD EAS1 <ENTER>") and typing "EASETUP <ENTER>".
The files which are sent on the diskette are:
Filename Contents
CTY.DEF List of all states and counties and corresponding FIPS codes.
EVENT.DEF A list of all EAS 3 letter event codes and text description or each.
ORG.DEF A list of the 5 EAS 3 letter originator codes and a text description
of each.
EAS.INI Station Setup Information and PC Installation Information.
CTY.SEL Counties selected as counties in the station's listening area.
RPSH.SEL Required pre-selected header codes selected for the station.
OPSH.SEL Optional pre-selected header codes selected for the station.
The DEF files are definition files that do not change with user setup. These files must be updated as this information changes or expands. The INI and SEL files contain data that is selected for the station or PC. These files will change as the setup changes.
When the EAS setup software is started the first time on the PC, run main menu item 6 to enter the PC installation data. This will select the serial port to be used to download to the encoder/decoder, and it will select time zone information for the PC. It should be necessary to enter this information only once after the installation.
3 Description -
The setup program allows selection and downloading of the following information:
Station Information -
Station call letters.
Passwords (operator and optional technician).
State Primary.
Station time zone.
Station Daylight Time.
Station originator code.
Encoder/Decoder Setup Information -
Counties in Listening Area - Up to 31 county names and state abbreviation
(plus the code for all counties in the state of license)
FIPS codes with corresponding state abbreviations and corresponding state
FIPS codes from up to 6 states.
Counties to be sent with required monthly tests.
Counties to be sent with required weekly tests.
Pre-selected Header Codes - 4 (may be expanded to 8) required pre-selected
header codes and priorities. Up to 20 optional pre-selected header codes and
priorities.
Date and Time -
Current UCT date and time from the PC.
The program keeps a copy of your setup on a disk file so that the next time you run the program, you begin with your last setup. This makes it easy to quickly make minor changes to the setup.
4 Operation -
The program is started from the DOS prompt by typing EASETUP. The first thing that the user will see is the following main menu:
Gorman-Redlich EAS1 Encoder/Decoder V 1.5 PC Setup Program
Should be run on EAS1 Encoder/Decoder V 5.9 and later.
MAIN MENU
1 Enter Encoder/Decoder Setup Information
2 Send the data over the RS232 port
3 Reserved for future expansion
4 Reserved for future expansion
5 Set the Encoder/Decoder Time to the PC Time
6 Enter PC installation data

Type the number or letter of the
menu item to select it
From this main menu the selections are made by entering the corresponding numbers
1 through 6 or q to exit.
4.1 Item 1 - Enter Encoder/Decoder Setup Information
When this Item is selected, the user will be allowed to select all the necessary setup data to allow the encoder/decoder to function properly at that station and in that listening area. The following subsections will discuss the various items that are to be selected.
4.1.1 Entering Station Setup Information
In all cases, use the ARROW keys to move the cursor adjacent to the
desired entry. When the cursor is beside the desired entry, strike the ENTER
key. The following sections describe the manner in which each item is entered.
An example of the station setup entry screen follows:
Enter Call Letters, Operator password, Technician password

4.1.1.1 Call Letters - The call letters may be up to 8 characters.
With the exception of '+', '-', delete character, or control characters (below 20H,
'space' character), any ASCII character may be used in the call letter field. After
selecting call letter entry with the ENTER key, type all the letters of the call. If
it is not 8 characters, finish it with spaces. After 8 characters and spaces have
been entered, the cursor will exit the call letter field. In case of a mistake,
repeat the process.
4.1.1.2 Station Operator Password - A 4 digit password to allow an operator
to compose an alert or send an alert. The password can contain only digits from
0-9. All 4 digits must be entered. In case of a mistake, repeat the process.
4.1.1.3 Station Technician Password - A 4 digit password to allow a
technician to set modulation levels and change other setup information on the encoder
decoder. This password can be made the same as the operator password if only one
password is desired. The password can contain only digits from 0-9. All 4
digits must be entered. In case of a mistake, repeat the process.
4.1.1.4 Station State Primary - Striking the ENTER key with the cursor beside
the state primary field will toggle the selection between either "Station is a state
primary" or "Station is not a state primary". Leave the entry field
when the correct display is showing.
4.1.1.5 Station Time Zone - Striking the ENTER key with the cursor beside the
time zone field will sequentially display each of the following time zones: Atlantic,
Eastern, Central, Mountain, Pacific, Alaska, and Hawaii. Leave the entry field when
the correct display is showing.
4.1.1.6 Station Daylight Time - Striking the ENTER key with the cursor beside
the daylight time field will toggle the selection between either "Station goes on
Daylight Time in April" or "Station does not go on Daylight Time in
April". Leave the entry field when the correct display is showing.
4.1.1.7 Station Originator Code - Striking the ENTER key with the cursor
beside the originator field will sequentially display each of the following originator
codes: EAN, PEP, WXR, CIV, and EAS. Leave the entry field when the correct display
is showing.
4.1.2 Selecting Counties in the Station's Listening Area
After the station information is entered, the county codes must be
selected. The state selection screen will appear to show what states are presently
selected as in the following example:
This is county and state selection. You may have up to 6 states.
ARROW keys - Position cursor to desired option
ENTER key - Select option
DELETE key - Remove the state the cursor is on
q key - Exit county and state selection
_ Display current selected states and
counties
Add a new state
Edit OH
Edit PA
Edit WV
From this screen it is possible to:
1) display the currently selected counties and associated state,
2) add a new state and selected counties from it,
3) edit (add or delete counties) for any of the currently selected
states.
4) delete the state and all its county selections.
The cursor will initially appear on the line with "Display current
selected states and counties". The cursor may be moved up or down to the other
lines to make selections. Once the cursor is positioned on the line for the desired
operation, the <ENTER> key is pressed to make the selection. In the case of
the "Edit" lines, the DELETE key may be pressed to delete the state and its
selected counties. Whenever the state and county selections are satisfactory,
pressing the "Q" key will exit the county selection screen.
When the first item is selected, county codes previously selected are
displayed on the screen. This screen may be exited back to the state selection
screen by pressing any key. By using this function, it is easy to determine whether
the selections are satisfactory. If so, the county selection function may be exited
with the "Q" key. The following screen is an example of this display:
From OH:
009 Athens 045
Fairfield 049 Franklin 053
Gallia
073 Hocking 079
Jackson 089
Licking 105 Meigs
167 Washington
From PA:

Allegheny 005 Armstrong 007
Beaver
009 Bedford 001
Berks 013
Blair 015 Bradford
017 Bucks 019 Butler
From WV:
107 Wood
If it is necessary to add counties from a state other than the states
shown selected, the first item "Add a new state" must be selected. In this
case, the state abbreviation must first be entered to access the counties for that state
(for instance: OH for Ohio). If it is only necessary to add or delete counties from
one of the states already selected, move the cursor down to that state and press
<ENTER>. Whether a new state is being added or an existing state is to be
edited, the county selection screen is used. The following screen is an example of
the county selection screen:
Choose from OH. Use arrows, pg-up/down, <ENT> to select, q to quit

16 Counties selected from 5 States
When the county selection screen is entered, the first 44 counties for that state will be displayed in alphabetical order. These counties may be selected or de-selected by moving the cursor with the arrow keys to a county and pressing the ENTER key. When a county is selected, it will have a >> symbol beside it, and it will be included in the selected county list that is being built in the bottom portion of the screen. If a county is mistakenly selected, simply move the cursor to the county again, press enter, and the >> symbol will disappear, and it will be removed from the list. Counties for that state beyond the 44 shown on the display, may be accessed by the use of the page up and page down keys. The selected county list at the bottom of the screen shows all counties currently selected along with their state abbreviations. In addition, the prompt at the bottom reports the number of counties and states currently selected.
When all desired counties have been selected, press the "Q" key
on the PC to exit back to the state selection screen. The second item, "Display
current selected states and counties" may again be selected to review the county
selections. The process of adding or editing states and counties and reviewing
selections is continued until the selections are satisfactory, and then the state
selection screen is exited by the "Q" key.
4.1.3 Entering County of License
Upon exiting the selection of counties in the station's listening area, it is possible to enter the county of license. Since the county of license must be one of the counties in the listening area, this selection must come after selecting the counties in the listening area. The selection screen will appear as follows:
Select your County of License.
ARROW keys - Position cursor on desired county
ENTER key - Select or Deselect a county
q key - Exit screen after selection

If a county was previously selected as the county of license, it will be indicated with the >. If the counties in the listening area have been changed, make sure that the county of license indicated is the one that you want. When counties in the listening area change, the county of license defaults to the first county in the list.
Select the county of license in the same manner as the counties in the listening area were selected - by moving the cursor to the desired county and pressing <ENTER>. The software will allow only one county to be selected, but one county must be selected before exit. When the desired county has been selected, exit this screen by pressing the "Q" key.
4.1.4 Entering Counties for Required Monthly Tests
Upon exiting the selection of counties in the station's listening area, it
is possible to enter the counties to be sent with an outgoing, and checked for an
incoming, required monthly test. Since these counties must be among the counties in
the listening area, this selection must come after selecting the counties in the listening
area. The selection screen will appear as follows:
Select counties for Required Monthly Test:
ARROW keys - Position cursor on desired county
ENTER key - Select or Deselect a county
a key - Select all counties
q key - Exit screen after selection

Any counties previously selected to go out with an RMT will be indicated with the >. If the counties in the listening area have been changed since the last RMT counties selection, make sure that the counties indicated are the ones that you want. If counties in the listening area have been changed, RMT county selections revert to the default which is all counties selected. Select or deselect these counties in the same manner as the counties in the listening area were selected - by moving the cursor to the desired county and pressing <ENTER>. When the desired counties have been selected, exit this screen by pressing the "Q" key.
The required monthly test counties can include any up to all of the counties in the listening area. At least one location must be selected in order that a valid RMT header will be sent. If it is attempted to deselect all locations, the county of license will be automatically selected.
In addition to the individual counties, there is a code available for the entire state of the county of license (in this example, Oklahoma). If this selection is made, the decoder will respond to the code for all counties in the state of license. However, the encoder will not include that code with the list of counties in an outgoing header. To use that code in an outgoing RMT header, the header must be composed rather than using the RMT key.
4.1.5 Entering Counties for Required Weekly Tests
Upon exiting the selection of counties for the required monthly test, it
is possible to enter the counties to be sent with an outgoing required weekly test.
Since these counties must be among the counties in the listening area, this selection must
come after selecting the counties in the listening area. The selection screen will
appear as follows:
Select counties for Required Weekly Test:
ARROW keys - Position cursor on desired county
ENTER key - Select or Deselect a county
a key - Select all counties
q key - Exit screen after selection

Any counties previously selected to go out with an RWT will be indicated with the >. If the counties in the listening area have been changed since the last RWT counties selection, make sure that the counties are shown correctly. If counties in the listening area have been changed, RWT county selections revert to the default which is, only the county of license selected. Select or deselect these counties in the same manner as the counties in the listening area were selected - by moving the cursor to the desired county and pressing <ENTER>. When the desired counties have been selected, exit this screen by pressing the "Q" key.
The required weekly test counties can include any up to all of the
counties in the listening area. At least one location must be selected in order that
a valid RWT header will be sent. If it is attempted to deselect all locations, the
county of license will be automatically selected.
4.1.6 Entering Pre-selected Header Codes
The four mandatory pre-selected header codes for EAN, EAT, RWT, and RMT, are built-in and do not need to be entered in this step.
Up to 20 optional preselected header codes may be selected. Each of
the pre-selected header codes contains three parts:
1) Event.
2) Priority.
3) Counties in the station's listening area which are affected.
Initially, the preselected header codes are summarized in the main
preselected header code screen. The first 10 preselected header codes are shown
initially. By pressing the PAGE DOWN key, the next 10 will be shown. Pressing
the PAGE UP key will return to the first 10. An example of this screen is as
follows:
Select your Optional Preselected Header Codes.
PAGE keys - Switch to another 10 preselected header codes
ARROW keys - Position cursor on desired entry
ENTER key - Edit or add an entry
DELETE key - Delete an entry

The cursor may be positioned beside a "Not Used" entry and
<ENTER> pressed to add a new entry. Likewise, it may be positioned beside an
existing entry and <ENTER> pressed to edit or review an existing entry. In
either case a selection screen for selecting events and priorities and a selection screen
for selecting associated counties in the station's listening area will be entered.

A selection arrow will appear beside any selections that may have been made previously. By pressing the arrow keys the cursor may be moved to any event, and <ENTER> pressed to select that event. Selecting one event deselects any other event had been selected for this code number. After selecting the desired event, use the arrow keys to move the cursor down to the priority section at the bottom and select the desired priority in the same manner. When the selection for this entry is complete, exit by pressing the "Q" key. This screen cannot be exited until both an event and priority have been selected.
When the event/priority selection screen is exited, the counties affected
must be entered in the preselected header code county entry screen. A screen similar
to the following will appear:
Select counties for Preselected Header Code number: 1

Only the counties in the station's listening area that have previously been selected will be shown. In this example all counties have been selected. Any of these counties may be de-selected by moving the cursor to the left of them and pressing <ENTER>. In addition to selecting or de-selecting individual counties with <ENTER>, pressing "A" will select all counties. When the desired selections have been made, press "Q" to exit this screen back to the main preselected header code screen.
If the counties in the listening area have been changed since the preselected header codes were last entered, review the existing selections carefully and make changes as necessary. It is likely that these selections will now be incorrect, if the counties in the listening area were changed.
When all entries are completed, press "Q" in the main
preselected header code screen to exit the preselected header code entry section and
return to the main menu screen. The Encoder/Decoder Setup Information entry is now
complete. It may be reviewed and/or changed by again entering main menu item 1.
4.2 Item 2 - Sending the Data over the RS232 port
With the RS232 cable connected to both the PC and the Encoder/Decoder as
described in the introduction, the data just entered may be transferred from the PC to the
Encoder/Decoder. Insure that the Encoder/Decoder is powered up and in the normal
display with the Decoder Scanning and the Encoder Ready (ie: not in a setup menu,
processing an alert, sending a message, etc.), and the RS232 cable is connected from the
computer port of the encoder/decoder to the correct PC COM port. Press the 2 key,
and the data will be sent to the Encoder/Decoder. The data being sent is displayed
at the bottom of the PC screen during transfer. When the transfer is complete, the
screen returns to the main menu display.
There are two types of data errors that may occur during attempts to download to
the encoder/decoder - timeout errors and echoed data errors. Each character that is
transmitted to the encoder/decoder from the PC is echoed back to the PC by the
encoder/decoder. The EASETUP program then compares the echoed character to the
original character, and it reports an error if they are different. A timeout error
occurs when the PC waits longer than a few seconds for the echoed character from the
PC. When either error occurs, the download is aborted, and the software returns to
the Main Menu. Once the cause of the error is found and the error cleared, the
download may be attempted again. Typical causes for the errors are: RS232 cable not
connected, encoder/decoder not powered up, encoder/decoder not in main display (ie: in
some menu function or otherwise busy), and PC set to wrong COM port. If no problem
is found, re-boot the encoder/decoder, and try again.
4.3 Item 3 - For future expansion
4.4 Item 4 - For future expansion
4.5 Item 5 - Set the Encoder Time to the PC Time
Pressing 5 will result in the following display:
EAS Time Setting Function
EST: 12/12/96 19:13:00
UCT: 12/13/96 00:13:00
Press <ENTER> to download time to Encoder/Decoder
The display will show the PC local time and UCT (Universal Coordinated Time or Greenwich Mean Time). The times are displayed so that the user can check to make sure they are correct. The difference in hours for UCT - Local Time is: AST=4, EST=5, CST=6, MST=7, PST=8, AST=9, HST=10; ADT=3, EDT=4, CDT=5, MDT=6, PDT=7, ADT=8, and HDT=9.
If the PC clock contains the correct local time, and the correct PC time zone and daylight time information has been entered (see next section), then the UCT time will be correct. The PC local time may be corrected using the standard DOS and/or Windows time setting functions. On the date that the time change occurs, most PCs will not change the time automatically, and this must be done manually. However, if this is done and the PC is reading the correct local time, the program will display these two times correctly.
Insure that the Encoder/Decoder is powered up and in the normal display with the Decoder Scanning and the Encoder Ready (ie: not in a setup menu, processing an alert, sending a message, etc.) and the RS232 cable is connected from the computer port of the encoder/decoder to the correct PC COM port. By pressing <ENTER>, the UCT time will be downloaded to the encoder/decoder. If the encoder/decoder has been given the correct station time zone and daylight time information (see sections 4.1.1.5 & 4.1.1.6), then the encoder decoder will display the correct local time after this download.
There are two types of data errors that may occur during attempts to download to
the encoder/decoder - timeout errors and echoed data errors. Each character that is
transmitted to the encoder/decoder from the PC is echoed back to the PC by the
encoder/decoder. The EASETUP program then compares the echoed character to the
original character, and it reports an error if they are different. A timeout error
occurs when the PC waits longer than a few seconds for the echoed character from the
PC. When either error occurs, the download is aborted, and the software returns to
the Main Menu. Once the cause of the error is found and the error cleared, the
download may be attempted again. Typical causes for the errors are: RS232 cable not
connected, encoder/decoder not powered up, encoder/decoder not in main display (ie: in
some menu function or otherwise busy), and PC set to wrong COM port. If no problem
is found, re-boot the encoder/decoder, and try again.
4.6 Item 6 - PC Installation Data
The serial port to be used in downloading must be selected, if this has not been done in previous sessions. Selecting item 1 will allow selection of either COM1 or COM2. This selection should be made based upon which physical PC port to which the DB9 cable will be connected.
The time zone for the PC, and whether the PC time zone changes to daylight time in April, must be entered for the downloaded times to be correct. Note that the information is not asking whether the PC is currently on daylight time. It only needs to know whether the PC ever goes on daylight time. Given this information, it can check as to when it needs to be on daylight time.
The following is an example of the installation screen:
Select PC COM Port, PC Time Zone Daylight Time
ARROW keys - Position cursor on desired parameter
ENTER key - Make the desired selection
q key - Exit screen after selection
_ COM1 is the selected PC COM port
Central Time Zone
PC does not go on
Daylight Time in April
4.7 Item q - Exiting to DOS
When finished with the setup program, it may be exited to return to
the DOS operating system by pressing the 'q' key. The familiar DOS '>' prompt
will then be seen on the screen.
