2 Communication between electronic load and PC

Before using the remote operation mode, please make sure that the baud rate and communication address in electronic load are the same as in the computer software, otherwise, the communication will fail, you can change the baud rate and communication address from the front panel or from computer.

1． Address: the range is from 0 to 254,default setting is 0

2． Baud rate: 4800,9600,19200 and 38400 are selectable, default setting is 4800

3． Data bit：8 bit

4． Stop bit：1

5． Parity：None

Parity=None

Start Bit

8 Data Bits
