Application

A MicroTech II LonWorks Communications Module connects the MicroTech II Unit Controller to
the Building Automation System (BAS) on a LonWorks network. It is the interface adapter for the
exchange of LonTalk variables between the network and the unit controller. The MicroTech II
LonWorks Communications Module translates the LonWorks variables of the profile into the native
information of the unit controller. Figure 2 shows the MicroTech II LonWorks Communications
Module and Unit Controller integrated into a BAS. Refer to the appropriate Unit Operation manual
for keypad details. See Reference Documents for part numbers.
