Nortec LINKS 2 NHTC Installation And Operation Manual page 7

BACnet/IP
A standard CAT-5E cable with an RJ-45 (Ethernet) jack is to be connected to port 3,4, or 5 on the
gateway. 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 2 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.
Gateway Configuration
Links 2 is configured for each protocol at the factory, prior to final testing. Baud rates are
adjusted to the following values by default:
Protocol
BACnet MS/TP
BACnet / IP
Johnson N2
LonWorks
Links 2 packages require network addresses in order to communicate with a BMS system. In
most cases addresses information is factory configured during final testing. If the humidifiers
were ordered before BMS address information was available, Links 2 would be figured to a default
address. Please contact the factory for the configuration tools to allow field modification of the
address parameters.
