Request CAP Software Update

Having the latest software version gives access to the newest features of the CAP-DEC 1 user interface and more. Click here for information about compliance with FCC R&O 22-75. In order to meet the new FCC requirements, both the CAP-DEC1 and the Gorman Redlich EAS1 encoder-decoder must be updated. Using the CAP-DEC1 with 3rd-party EAS equipment may require update from the manufacturer or replacement of equipment.

Software v2.81 or above is now required to be Part 11 compliant.  Your current CAP-DEC 1 version is shown in the top “title bar” of the unit’s on-screen user interface and will include the version number and build date in the format vX.XX.X build MM.DD.YYYY. The latest available build is shown in the “Available Version” box on the interface (v2.80+ only).  If you need your unit to be updated to the latest version, please use the Request Update form below.

Gorman-Redlich recommends ensuring that your CAP-DEC1 operating system is kept up to date, including installing all Windows 10 updates. If your unit is still running Windows 7, please contact us to upgrade to Windows 10.
