x
GND:
Both GND terminals are internally connected to the same point and represent Chassis Ground of
the unit. Use either terminal to the GND of the external IR Receiver.
x
IR Input:
Connect to IR Output of an IR Receiver such as the 4such as the 490-90, 291-10, 480-80 or
other.
Use 3-Conductor 18-24AWG wire (4-Conductor if using the STATUS line). Gauge varies by wire run
distance. See
Figure 9
for wiring examples.

These RJ45 ports are used for interfacing the SmartPad LCD unit directly to the CM8X8/MRC Controller
and/or Expansion CM8X8/MRC Keypads. The CSPLCD can interface to the CM8X8/MRC Products in two
fashions via this connection:
1. Via IR along the dedicated IR lines of the MRC’s CAT5 connection (Pins 4 & 5) (CM8X8/MRC88 &
MRC44)
2. Direct to the CM8X8/MRC88 processor via the internal RS485 communication lines
(Future Feature)
Controller:
This port is used to connect the CSPLCD either directly to the CM8X8/MRC88 Controller or to an existing
CM8X8/MRC88 Keypad’s Expansion port. Connect using CAT5 cable terminated at both ends with RJ45
connectors (using the EIA/TIA 568B standard) from the CM8X8/MRC88 Controller/Amplifier (Zone Keypad
Connection located on the rear of the unit) into the RJ45 connector marked “Controller” on the rear of the
CSPLCD keypad.
Note:
When the CSPLCD is the last Keypad connected in line with the CM8X8/MRC88, the Zone
Termination Jumper (
Figure 3 – 16)
needs to be installed.
