BACnet/IP
A standard CAT-5E cable with an RJ-45 (Ethernet) jack is to be connected to the Ethernet port
on the Links XPS module. Refer to wiring diagrams in this manual.
Cable Shielding
The cable’s shield should be connected to the shield terminal at the BMS system only, and not
the Links XPS module.
As well the cable shield should be connected at the lead unit only and not at subsequent units.
For long chains the shield would appear as:
Unit 2 to Master - Shield connected at master only.
Unit 3 to Unit 2 - Shield connected at unit 2 only.
Unit 4 to Unit 3 - Shield connected at unit 3 only.
And so forth.
