APPENDIX A — BAS COMMISSIONING (CONT)
If you set the Default IP address on the controller setup Ports tab
and then change the rotary switches, you must do one of the fol
-
lowing to correct the IP address in the controller:
• Go to the controller setup Ports tab and click the Update IP
Address.
• Cycle the controller’s power.
You will then need to correct the IP address in SiteBuilder.
NOTE: The default address is an intranet address. Data packets
from this address are not routable to the Internet.
TO SET THE PORT S2 ADDRESS AND BAUD RATE
The address should be in one of the following ranges based on the
port’s use.
• For ARCNET, the range is 1 to 255.
• For MS/TP, the range is 0 to 127.
You set the this address on the LS-1628u’s three rotary switches.
Set the left rotary switch to the hundreds digit, the middle switch
to the tens digit, and the right switch to the ones digit.
FOR MS/TP, SETUP AUTOBAUD OR THE PORT’S BAUD
RATE
1. On the controller setup BACnet tab under Port S1, select the
MSTP Baud Rate or select Yes for MSTP Autobaud. The
default is 76,800 bps.
NOTE: See To set up AUTOBAUD for details.
If not using autobaud, enter the identical baud rate for all
devices on the same MS/TP network segment.
2. Click Save.
TO SET THE PORT S2 AND BAUD RATE
For MS/TP, setup autobaud or the port’s baud rate.
1. On the controller setup BACnet tab under Port S2, type the
address in the MSTP Address field. The address must be in
the range 0 to 127.
2. Select the MSTP Baud Rate or select Yes for MSTP Auto
-
baud. The default is 76,800 bps.
NOTE: See To setup autobaud (page 82) for details.
If not using autobaud, enter the same baud rate for all services
on the MS/TP network.
3. Click Save.
TO CONNECT THE LS-1628U TO THE ETHERNET
Connect an Ethernet cable to the Gig-E Ethernet port located on
the top of the LS-1628. Be careful NOT to plug your cable into the
Service Port (located on front of Controller).
NOTE: If your system has controllers on different IP subnets sep
-
arated by an IP router, you must configure one controller on each
subnet as a BACnet Broadcast Management Device (BBMD). Do
not configure more than one BBMD per subnet as this may cause
circular routes. See "Setting up BACnet Broadcast Management
Devices (BBMDs)" in SiteBuilder or WebCTRL Help.
TO WIRE A BACNET/ARCNET NETWORK
1. Turn off the LS-1628u’s power.
2. Check the communications wiring for shorts and grounds.
3. Connect the communications wiring to Port S1’s screw termi
-
nals labeled Net+, Net-, and Shield.
NOTE: Use the same polarity throughout the network
segment.
4. Set the Port S1 Configuration rotary switch to 2.
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 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.
NOTE: Set the Port S1 Configuration rotary switch to:
0 if port is not used
1 for MS/TP
2 for ARCNET
4 is for future use.
Default baud rate for MS/TP is 76.8 kbps.
CAUTION
If you are using Port S1, the rotary switches also determine
that network's address. Although the ARCNET address range
is 1 to 255, the Default IP address range is 1 to 253. Setting
the rotary switches to 0 will set the Default IP address to 1.
Setting the switches to 255 will set the Default IP to 253. Do
not set the switches to 254.
