P/N 06-237058-001 2-49 February 2012
The RS485 communications circuit is power-limited. Figure 2-41 shows typical interconnections among the
ARIES NET
Link control unit and the peripheral devices using both a single and dual communications
channel.

I nsta ll ation Notes :
RS4 8 5 circuits must be terminated at the first and last device in the circuit.
First device is the main Keypad/Display with termination resistor SW2
(located on the back side of the board) set to the ON (terminated) position.
For Remote Keypad/Display and RDCM boards, set termination resistor SW2
to the OFF (open) position for intermediate assemblies by moving the small
white switch lever. Leave in the ON position if assembly is the last device in
the circuit. For ATM-L or ATM-R assembly termination settings, refer to the
Model ATM-L/R Series Drivers Installation Manual, P/N 06-236179-002.
For remote synchronization between RDCMs, R-LAMs and the control unit
(having power supply connections common to all), install wire from
LED SYNCH OUT+ of the originating device to LED SYNCH OUT- of the first
remote peripheral device. Continue for as many remote devices in the system.
Note: An R-LAM cannot be an originating device.
For Dual Channel Installation
On the R-LAM, the location of these
2 connectors is reversed; i.e., its
J 6
(PWR IN) 24 Vdc connector is at
the top, and its
J8 (RS4 8 5) bus
connector is at the bottom.
