6 CONNECTIONS
CN1
is the data link connector: a DB9 male connector that hosts the RS485 signals with a pinout compatible
with OPD EXP and mini-OPD EXP RS485 interface for direct connection using a 1-to-1 serial cable.
CN1 Pin # Name Description
1
0V signal reference voltage

5
Term + positive polarization/termination
6
TX_RX -
RS485 half duplex inverting signal (Tx /
Rx) 6 – 7 internally shorted
7
TX_RX -
8
9
Term - negative polarization/termination
Please notice that the
remote keypad RS485 interface is HALF DUPLEX
so only 3 wires/signals (TX_RX+,
TX_RX-, 0V) can be connected between devices.Pins 2 and 3 are internally shortened and so also pins 6
and 7.In order to succesfully communicate with OPD EXP or mini-OPD EXP, that have FULL DUPLEX
RS485 interface, you have to shorten the same pins also at drive side or connect both pins 2, 3 and 6,7 (the
supplied serial cable use the latter).

The first cabling scheme is always recommended and it is mandatory in case of “long” and/or multidrop
connection.
