To wire the BACnet MS/TP network
1 Turn the i-Vu® Open Link's power off.
2 Check the communications wiring for shorts and grounds.
3 Verify that the Port S1 jumpers are set to 485-2w.
4 Set the MS/TP baud rate DIP switches 7 and 8 to match the baud rate of the Open network. The default is
76.8k.
5 Connect the i-Vu® Open Link's Port S1 to the Open MS/TP network. Use the same polarity throughout the
network segment.
