Connections to the MATRIX BACnet Router are made via ports located on the left side of the controller
board. As illustrated below, the device has ports for Main Power, EIA-485 network connectivity and
Ethernet connectivity. Depending on the variant of MATRIX BACnet Router purchased, your application
may involve using only one of the two available EIA-485 network ports. Other unused ports such as RS-
232 and USB are reserved for future use.
