Troubleshooting the Data Module 10
Verifying the COM Port 10
If the DEFINITY system connection test does not pass,
1. Verify that the cable between the data module and the PC serial port is properly
connected.
If it is, go to step 2.
If it is not, correctly connect the cable between the data module and the PC
serial port. If the problem still exists, replace the cable to be sure you do not
have a faulty cable. If the problem still exists, go to step 2.
2. Verify that you have selected the correct COM Port for the data module.
If you have, go to step 3.
If you have not, change the COM Port selection. Go to “Setting Up The COM
Port” on page 10-38 for instructions on how to change the COM Port. If the
problem still exists after you change the COM Port selection, go to step 3.
3. Consult your PC user guide or its manufacturer’s technical support to see how
to tell if your COM Port has been disabled.
4. Use the terminal emulator to be sure that your PC is communicating with the
data module. See “Using a Terminal Emulator” on page 10-39.
5. Connect the data module voice terminal to another PC where BCMS Vu is
working properly. If the datamaster voice terminal works properly on the new
PC , there is a problem with your PC . Contact your technical support.
