APPENDIX A — BAS COMMISSIONING (CONT)
6. Turn on the controller’s power.
7. To verify communication with the network, get a Module Sta-
tus report in the WebCTRL interface for a controller on the
ARCNET network.
NOTE: This step requires that you have set up the router in
SiteBuilder and downloaded it from the WebCTRL interface.
TO WIRE TO A BACNET MS/TP NETWORK
An MS/TP network can be wired to either Port S1 or Port S2.
1. Turn off the LS-1628u’s power.
2. Check the communication wiring for shorts and grounds.
3. Connect the communications wiring to the Port S1 or Port S2
screw terminals labeled Net+, Net-, and Shield.
NOTE: Use the same polarity throughout the network
segment.
4. If you are using Port S1, set the Port S1 Configuration to
switch to 1.
NOTE: If Port S1 is not being used for any network, set this
rotary switch to 0.
5. If the LS-1628u is at either end of a network segment, set the
port’s End of Net? switch to Yes.
NOTE: The controller’s End of Net switch applies network
termination and bias. If the controller is at the end of a net-
work segment that includes a DIAG485 that has its Bias
jumper in the ON position, set the End of Net? switch to
No and connect a 120 ohm termination resistor to the Net+
and Net- terminals. See DIAG485 Technical Instructions
for more information.
6. Turn on the controller’s power.
7. To verify communication with the network, get a Module Sta-
tus report in the WebCTRL interface for a controller on the
MS/TP network.
NOTE: This step requires that you have set up the router in
SiteBuilder and downloaded it from the WebCTRL interface.
