• Connect the RS232 link between the DTE (port COM) and the M1306B (DCE).
• Configure the RS232 port of the DTE as follows:
Bits per second: 115.200 bps,
Data bits: 8,
Parity: None,
Stop bits: 1,
Flow control: hardware.
• Using a communication software such as a Hyperterminal, enter the
AT↵
command. The response of the M1306B must be
OK displayed in the
Hyperterminal window.
• If the communication cannot be established with the M1306B, do the
following:
Check the RS232 connection between the DTE and the M1306B
