Troubleshooting

Optical Interface Cable

Many manufactures of PC software and hardware use the COM (serial) port(s). It is difficult to predict potential COM port conflicts. If the Optical Interface Cable’s wand tip is not flashing, there are a few steps that can be taken in order to find the source of the problem.

∙Make sure that the Optical Interface Cable is securely plugged in. The Optical Interface Cable may appear to be properly connected but only be partially plugged in.

∙Try a different serial port. If the PC has more than one serial port, try another port to see if the Optical interface flashes.

∙Determine if you have any other Windows programs using the serial port. PC faxing programs or other programs that use the COM port can cause conflicts during data transmission. To verify that no other programs are running and causing communication problems, shut down your computer and restart it before you run EventView software.

∙Verify that your serial port settings are correct. In Windows 3.1 you can use the Microsoft Diagnostics program, MSD.EXE, to find out the number of installed serial ports in your PC, and their settings. These settings should be the same as those displayed in the advanced section of “Ports” in the Windows 3.1 Control Panel. Exit Windows or restart the computer in MS-DOS mode before running MSD. If you have an internal
