Chapter 4: Using the Commands

Test G24-L Communication

This is a preliminary step. During this step, the ability to communicate with the G24-L using AT commands is tested.

Start

Error

Send 'AT'	No Echo	Check RS232 Connection or
		Change UART Baud Rate

OK

End

Figure 4-5: Test G24-L Communication

Communication example:

AT
ATE1	//By default, the echo should be enabled
AT
OK	//Confirm that G24-L replies with OK

Basic Configuration

These are optional steps. If required, specific RS232 pin behavior can be selected. Extended error notification is recommended for debugging and field-support purposes.

Configure the RS232 Connection (Optional)

Baud rate, line behavior and flow control

(for example, “AT+CBUAD=115200”, “AT&Cx”, “AT&Dx”, “AT&Kx”)

Note: If the baud rate has been changed, you must change the baud rate of the UART as

well.

Enable Extended Error Messages (Optional)

(for example, “AT+CMEE=2 or 1”)

Basic Commands (Optional)
