• Catch one end of the DIN rail latch (at the bottom
of the module, under one edge of the DIN rail, then
snap the other latch onto the opposite side of the
DIN rail, as shown below:

WIRING THE MODULE
There are twelve total wire terminal points on this
module. Refer to the following table for the pin-out:
Wire terminal connections
Terminal
Position
Module
Power
RS-232 RS-422 RS-485
1 -RX
2 +RX
3 (Not Used)
4 -TX -RX/-TX
5 +TX +RX/+TX
6 (Not Used)
7 -24 VDC
8 (Not Used)
9 +24 VDC
10 GND
11 TX
12 RX
• 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 decid-
ed to use. Simply match the SIGNAL NAME
from the source device to match the SIGANAL
NAME of the module. All external communi-
cations wiring must conform with the Frick®
Proper Installation of Electronic Equipment in
an Industrial Environment publication.
RS-232 CONNECTIONS (Q4 and earlier only)
Refer to the following gure for the pin connections
showing how to wire a standard 9-Pin RS-232 connec-
tor directly to the Frick® Communications Converter
Module:
RS-232 Connections
Refer to the following gure for the pin connections
showing how to wire the Converter Module (converts
from RS-232 to RS-422/485) to the 10-pin Com-3 (PL6)
connector on the Quantum™:
Com-3 (PL6) RS-232 Wiring To Frick® Communications
Converter Module
RS-422 CONNECTIONS
Refer to the following gure for the pin connections
showing how to attach a 4-wire RS-422 cable directly
to the Frick® Communications Converter Module:
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 inter-
nally, without the user needing to provide it. It is a true
two-wire system. Refer to following gure for the pin
connections showing how to attach a 2-wire RS-485
cable directly to the Frick® Communications Converter
