To set up autobaud
The TV-MPCXP1628-NR 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.
NOTES
•
The received baud rate stays intact during power cycles.
•
We recommend you set the baud rate manually on the router for the network.
