5.9. RS-485 Interface Module (RIM)
Each HALO Controller, Receiver and Elevator Controller needs a RIM to interface to the RS-485 network that
terminates at the HALO Computer. The RIMs have a unique serial number that is associated to the locations on
the floor plans of the building, so that the computer can correctly show the location of an event occurring on
the system. Therefore, ensure that the correct RIM is installed at the corresponding locaton.
5.9.1. RIM LED Status
The 2 LED’s can be used to indicate a number of conditions to the installer. One LED is used to display
device status while the other LED is used to indicate network status.
During normal operation both LEDs should be “Steady On”.
LED behavior RED LED GREEN LED
OFF RIM not working, no power
source
No network detected
FLASHING Poor communication due to loose
or reverse wiring on Weigand
lines.
Communication failure – no
network address.
ON STEADY Normal Operation. Power and
Weigand is good.
Communication is good. Network
activity has been detected.
After both LEDs are “Steady On” test the RIM for communication by flashing a tag creating a TIC or TIF
alarm and the alarm created should be reported to the computer.
