4.2.2 Using the Configuration/Debug Port

To connect to the module’s Configuration/Debug port:
1 Connect your computer to the module’s port using a null modem cable.

2 Start the communication program on your computer and configure the

communication parameters with the following settings:

Baud Rate

57,600

Parity

None

Data Bits

8

Stop Bits

1

Software Handshaking

None

3 Open the connection. When you are connected, press the [?] key on your

keyboard. If the system is set up properly, you will see a menu with the

module name followed by a list of letters and the commands associated with

them.

If there is no response from the module, follow these steps:
1 Verify that the null modem cable is connected properly between your

computer’s serial port and the module. A regular serial cable will not work.

2 Verify that RSLinx is not controlling the COM port. Refer to Disabling the

RSLinx Driver for the Com Port on the PC (page 84).

3 Verify that your communication software is using the correct settings for baud

rate, parity and handshaking.

4 On computers with more than one serial port, verify that your communication

program is connected to the same port that is connected to the module.

If you are still not able to establish a connection, you can contact ProSoft

Technology Technical Support for further assistance.
