7. Restart the device by removing and reconnecting power input.

Baud Rate

When RS-422 / RS-485 terminal block is connected to the computer, please configure the general settings of your terminal program so you are able to communicate with the device
The default settings is shown below:

• Baud Rate: 38400
• Data Bit: 8 bit
• Parity: None
• Stop Bit: 1 bit
• Flow Control: none

Different baud rate is available with different firmware versions. If you wish to use a different baud rate for serial communication, identify the baud rate you wish to use from the link below:
