A special optional cable set C309 is needed. On the cable with three connectors the 14 pin connectors plugs onto the special functions connector on the DS7100 control panel.
The other 8 pins connector plugs onto the wiring connector of the keypads. When properly connected both keypads will be displaying "communicatioin Failure".
First on the keypad that is to receive the program, press the C and 2 keys together. It will display " receive".
ON the keypad that is to transmit (send). Its program, press the C and 1 keys together. It will display "Transmit".
The cable with only two 12 pin connectors mus be then plugged into the connectors at the bottom of the two keypads where the loop shorting plug are inserted (this cable must be plugged in last, after all steps above have been completed).
Within 30 seconds the transmitting keypad should display "done" and the receiving keypad should display "copy completed".
If the above displays don't apperar in 30 seconds, the copy failed. If so, momentarily remove power from the keypads and then repeat the above steps.
