Notes
When sending commands in succession, wait until a response is received from the first command before sending the next command.
The command timeout is 10 seconds. If no response is returned within 10 seconds after a command is sent, the command or response may not have reached the destination. Check the power supply of the device and the communication cable, and resend the command.
