Use this manual to physically install the communications module into the unit and connect the unit to your network. You also need the appropriate McQuay Engineering Data Sheet known as the Protocol Data Packet to integrate the unit into your network. The Protocol Data Packet contains addressing details, BACnet® and LonWorks® protocol information, and a list of the data points available to the network. See the Reference Documents section of this document for part numbers of Protocol Data Packets. These documents are available from your local McQuay International representative and for downloading at the McQuay International web site:

General Information

This manual contains the information you need to install the communication modules and incorporate it into the network, and maintain it.

! WARNING

Electric shock hazard. Can cause personal injury or equipment damage.

This equipment must be properly grounded. Connections and service to the MicroTech II control panel must be performed only by personnel who are knowledgeable in the operation of the equipment being controlled.

! CAUTION

Static sensitive components. Can cause equipment damage.

Discharge any static electrical charge by touching the bare metal inside the control panel before performing any service work. Never unplug cables, circuit board terminal blocks, or power plugs while power is applied to the panel.

NOTICE

This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with this instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

McQuay International disclaims any liability resulting from any interference or for the correction thereof.

Description

A MicroTech II BACnet MSTP Communications Module incorporates a MicroTech II unit controller into a BACnet MSTP Local Area Network (LAN). It is the interface to the Building Automation Network using BACnet objects.

The MicroTech II BACnet MSTP Communications Module is a printed circuit board that plugs onto the MicroTech II Main Control Board. Figure 1 shows an outline drawing of the BACnet MSTP communications module.

Application

The MicroTech II BACnet MSTP Communications Module connects the MicroTech II unit controller to the building automation system (BAS) on a BACnet MSTP Local Area Network. It is the interface adapter for the exchange of BACnet objects between the network and the unit controller. Figure 2 shows the communications module and unit controller integrated into a BAS.
