To temporarily access the LAN for commissioning and maintenance purposes, connect a por-
table adaptor to the stereo audio plug located on the lower edge of the Allure EC-Smart-Vue

The BACnet MS/TP adaptor must have an electrically-isolated RS-485 port. Other-
wise a ground path from the BACnet network will be made through the computer
that will disrupt BACnet network communications.
