Communication Connection (SM, AM, AG
Microprocessor)
The second wiring harness provided (p/n 159083G1) has a
connector fitted at either end and is the communications
connection between the unit microprocessor and the NIC.
To put it in the system:
1. Remove the existing wire located on P25 of the environmental
controller, cut off the red connector and reconnect the wires to
TB2 of the interface card. Ensure correct polarity.
2. Connect one end of the wire harness to TB1 of the interface
card; the other end connects to P25 of the environmental
controller.
Communication Connection (Level 0 and Level 10
Microprocessors)
To connect communications wire to the NIC, wire as described
above. However, some field modifications of the wiring
harnesses are necessary for connection to legacy systems. Level
0 and Level 10: Remove the red connector normally plugged into
P25. Wire to terminal connection P25.
