WIRING WITH THE CR110 CONTROLLER
The depiction below shows the connections that need to be made to allow communication between the TS110
display and the CR110 controller. If you do not have an RGX card use the following wiring scheme.
Figure 3-1 COM3 Pin Configuration
COM3: Using a 2 conductor cable with shield
connect a 9-PIN connector to one end. Con-
nect wires to the pins as show in Figure 3-1.
Connect the other end to a CR110 controller
card. Connect red (+) and black (-) cables to J13
and the shield (C) to J7 on the CR110. If you
are using multiple CR110 Cards make connec-
tions to the first card only as the communica-
tion wires are daisy chained between CR110
cards.
J11: Connect to 24V AC or DC
Power Source.
J12: (optional) Connect for MOD-
BUS RS-232 communication.
J10: (optional) Connect for MOD-
BUS RS-485 communication.
Note: J10 and J12 may not
be connected simultaneously.
To switch between J10 or J12
move switch S1 to either 485
for J10 or 232 for J12.
J7: Connect to COM 2 on the G55
Interface. Also can be used as a
MODBUS slave port (Baud rate
adjustable, default 9600kps).
24V Power Terminal: This terminal
should be connected to a 24V AC
or DC power source.
