Description

The BACnet Communication Module incorporates a Maverick I Unit Rooftop Unit into a BACnet local area network (LAN). It supports the BACnet MS/TP (EIA 485) data link layer (physical layer), BACnet over Ethernet (10Base-T), or BACnet/IP data link layers (physical layer).

The BACnet Communication Module is a printed circuit board that mounts directly on five pins on the top side of the Maverick I Rooftop Unit Controller (see Figure 1).

Five-pin header Four supporting stand-offs

Application

The BACnet Communication Module connects the Maverick I Unit Rooftop Unit Controller to a building automation system (BAS) on a BACnet local area network. It is the interface for the exchange of BACnet objects between the network and the unit controller. Refer to the McQuay Maverick I Unit Controller Operation Manual 1047 for unit controller details.

Reset Button

The reset button is used to reset BACnet addressing and configuration parameters. It is important to note that pressing and holding the Reset button for five seconds causes all BACnet data to revert to factory default values. For more information, see the Resetting the BACnet Communication Module section of this document.

Light Emitting Diodes (LEDs)

Six LEDs indicate communication activity and status of the BACnet Communications Module. These indicators are visible when the communication module is connected to the Maverick I Unit Rooftop Unit Controller and the unit is powered on (see Table 1 for descriptions of LED activity and Figure 2 for LED locations).
