1.
Locate a suitable source for the +24 volt DC
power. Using a minimum of 18 AWG stranded
wire, connect the MINUS wire to terminal # 7.
Connect the PLUS wire to terminal # 8.

All remaining connections will be based upon the
particular protocols that you have decided to use.
Simply match the SIGNAL NAME from the
source device to match the SIGNAL NAME of the
module. All external communications wiring must
conform with the Frick

RS-422 Connections
RS-485 Connections
Although typical RS-485 communications requires a
control signal to change the state of the RX/TX driver lines
to establish handshaking, this board incorporates a smart
feature that handles this handshaking internally, without
the user needing to provide it. It is a true two-wire system.
