Description
A MicroTech II BACnet Ethernet/IP Communications Module incorporates a MicroTech II unit
controller into an Ethernet Local Area Network (LAN). It is the interface to the network to Building
Automation Network using BACnet objects.
The MicroTech II BACnet Ethernet/IP 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
Ethernet/IP Communications Module.

Application
The MicroTech II BACnet Ethernet/IP Communications Module connects the MicroTech II unit
controller to the building automation system (BAS) on a Ethernet 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.
