Changing the Unit ID and baud rate
Most Alicat devices have serial-based communication capability. It’s important to make sure the baud rate of the computer or PLC the Alicat is connected to matches that selected on Alicat. Also, each Alicat connected to a single COM port (or virtual COM port) will need to have a unique Unit ID to allow the computer or PLC to distinguish them from each other.
See below for instructions on how to change the Unit ID and Baud Rate on your Alicat device.
