4. Communicating with the GL8200
After setting up the GL8200, communications can be established by directly sending AT commands to
the device using terminal software such as HyperTerminal for MS Windows. The following sub-
sections describe how this is done.
4.1. Communications Testing
4.1.1. Default Serial Interface
The default serial interface is 2-wire. To perform a communications test after the GL8200 has been
setup, do the following:

Connect the RS232 link between the external application (DTE) and the GL8200 (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: None

Using a communication software such as HyperTerminal, enter:
AT


When communications have been established, the GL8200 will respond wit
h an “
OK
”, which is
displayed in the HyperTerminal window.
If communications cannot be established with the GL8200, do the following:

Check the RS232 connection between the application (DTE) and the GL8200 (DCE).

Check the configuration of the port COM used on the DTE
4.1.2. Flow Control Option
To activate hardware flow control in 5-wire and 4-wire serial interfaces, do the following:

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 HyperTerminal, enter:
AT&K3

and
AT&W0
