Modem Wiring.
Note:
Modem will give 8 channels and leave D1, D2 & D3 (PA term) free for
other uses
For a ProDigi program Digicom Type to Gardiner
For Modem Mod+FF or MOD+PID
Remove link from 12V & Line Fault Terminals before connecting
ProDigi/Modem
Both the ProDigi and Gardtec Modem can be programmed direct from the
Gardtec
840
Modem Patch Lead
If the Gardtec
800 Series
Modem patch lead is to be used for direct connection to a PC
or Lap-Top It should be connected to SK3. The factory fitted link between 12V &
Line Fault must be removed. Full instructions on use of the Gardtec
800 Series
Modem Patch lead are supplied with the unit.
