Links XPS for Nortec GSTC/ SETC B+ |1
Overview
The GS/SE Links XPS Option allows for the integration of a Nortec GSTC/ SETC Series humidifier
within a BACnet, Johnson N2 or LonWorks network. This option features a gateway that has the
capability of converting information from the host Modbus protocol to a specified secondary
protocol.
The following protocol options are available, and must be specified at time of order:

Multi-Unit Systems (“Master/Slave”)
Up to 8 humidifiers can be chained and monitored through a single Links XPS package. In this
configuration, the unit with the Links XPS package is designated the “Master Unit”, while the
remaining 7 humidifiers are configured as “Slaves”. The master unit is connected to the
Building Management Systems (BMS). Each unit is separately addressed, it is possible to
monitor and control each unit individually.
Different networking configurations may be achieved depending on the type of network being
used. One networking example could have a Gateway installed inside the lead unit, which could
then be daisy-chained to successive units. In turn, the lead unit would connect to a Building
Management System (BMS) network via a shielded, twisted-pair connection. Please see wiring
section for additional detail. A second example could have a series of units directly connected
to an Ethernet network. This is only possible for BACnet communication and is essentially
referred to as a BACnet/IP configuration.

Field Installation or Retrofit Instructions
BACnet, LonWorks and N2 Modules:
Caution: Disconnect power before performing work inside cabinet.
Remove the Humidifiers front access panel. Install the bracket assembly using 8-32x ½” hex-
drive screws. Notice, 4 screws are used for the hinges, and the 5th screw for fastening the
bracket in place.

Wiring the Links XPS Module
Most of the wiring connections for the new Links XPS module will have already been finished at
the factory, however, there are a few connections that will need to be made to connect the unit
the Nortec GSTC/ SETC series humidifier. Refer the LINKS XPS wiring diagram included in the
package for details.
Module Power Connections: There will be a wire harness provided that will consist of a red and
blue wire. Both red and blue wires are terminated with a ring terminal.

a. The ring terminal of the red wire is to be connected to the power terminal on the 24V
side of the transformer located at the bottom, left of the electrical compartment.
b. The ring terminal of the blue wire is to be connected to the ground terminal on the 24V
side of the transformer.

Humidifier Communication Connection: On the Links XPS assembly there will be a CAT5 cable
with RJ45 connector.
This connector is to be plugged into the jack on the bottom right side of the humidifier main PCB
processor board (Keypad chip).
