Temporary Network Access
To temporarily access the BACnet MS/TP LAN for commissioning and maintenance purposes, connect a BACnet MS/TP Adaptor to the NET PORT au-
dio plug. Wire a standard ⅛” (3.5 mm) three-conductor stereo jack as shown below.
The BACnet MS/TP Adaptor must have an electrically-isolated RS 485 port. Otherwise a ground path from the
BACnet network will be made through the computer that will disrupt BACnet network communications.
