To set the Port S1 address and baud rate
The address should be in one of the following ranges based on the port's use:
•
For MS/TP Master, the range is 0 to 127.
•
For MS/TP Slave, the range is 128 to 255.
•
For Modbus, the range is 1 to 247.
You set this address on the TV-UC683T's controller setup pages.
The TV-UC683T can automatically receive or establish the baud rate on an MS/TP or Modbus serial network.
When you configure a device on the network for autobaud and then power it up, the device detects the incoming
baud rate on the network and sets its baud to match.
Autobaud does not work unless there is a device on the network, whether Carrier or third party, that has the baud
rate already set. You can manually set the baud rate on more than one device, as long as the rate is the same for
every device.
NOTE
The discovered autobaud rate stays intact during power cycles.
MS/TP
For MS/TP on Port S1, set up autobaud or the baud rate

on Port S1. See
BACnet Controller Properties
(page 39).
NOTES
•
If not using autobaud, enter the identical baud rate for all devices on the same MS/TP network segment.
•
If using autobaud, we recommend you set the baud rate manually on the router for the MS/TP network
segment.
Modbus
For Modbus Serial on Ports S1, set up autobaud or the baud rate
•
On the controller setup pages >
Modbus
tab >
Modbus RS-485
>

•
In the i-Vu® interface, on the navigation
tree, right-click your TV-UC683T > select

NOTE
For details on setting up your network, see the
Modbus Integration Guide
.
NOTE
If you set
Autobaud
or make other changes in the controller setup pages, you must upload the changes to
the system database the first time you access the controller in the i-Vu® interface. This preserves those settings
when you download memory or parameters to the controller.
