Updating the 7K repeater controller firmware
An EPROM containing new firmware for the 7K has also been included with the DAB. This new firmware provides better
integration between the DAB and 7K controller as well as providing new, generic, features to the 7K itself.
When version 2.04 firmware is installed in the 7K, the 7K will need to be re-initialized before it will work, and the
user will need to reload their program into the controller.
The DAB will work with any version of S-Com firmware that supported the speech synthesizer module, and you may elect
to defer the installation of the new controller firmware.
If your controller is not already at a 2.x version status, and you wish to utilize the new firmware, you will need to contact S-
Com regarding upgrading other components on the 7K controller board.
To change the Firmware, use an IC extraction tool to exert equal force on each end of the old EPROM while pulling
straight up. Place the old EPROM in conductive foam, and then install the new EPROM as shown in the picture below.
Pin one, on the notched end of the EPROM, should be facing towards the rear of the cabinet.
