To Set Up Autobaud - Carrier TV-OPT Installation And Startup Manual

To set up autobaud

The TV-OPT can automatically receive or establish the baud rate on a 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.
NOTES
•
The received baud rate stays intact during power cycles.
•
We recommend you set the baud rate manually on the router for the network.
MS/TP
MSTP Autobaud can be configured in either the:
•
Service Port controller setup pages > BACnet tab > Port S1 or Port S2
or
•
The i-Vu® interface, right-click your TV-OPT on the navigation tree, and select Driver Properties > BACnet
Router Properties > MS/TP Configuration on Port S1 or on Port S2. See BACnet Router Properties (page 30).
Modbus
Modbus Serial Autobaud can be configured in either the:
•
Service Port controller setup pages > Modbus tab > Modbus RS-485 > Port Configuration
or
•
The i-Vu® interface, right-click your TV-OPT on the navigation tree, and select to Driver Properties >
Communication Status > Modbus Serial
NOTE 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.
