By default, PMonitor monitors the COM1 port. If the utility displays an error
message stating that it is unable to open the COM1 port, it means that the
port is already being used by another utility.
You can either stop the other utility, and try again, or use a different COM
port for the PMonitor program. If you choose to use a different COM port:
1. Stop the PMonitor program
2. Connect your safe shutdown cable to a different COM port
3. Right click on the Monitoring Disabled icon, and select Options from the
context menu that appears. A dialog box, similar to the one below appears:
4. Open the list of COM ports, and select the COM port that the safe
shutdown cable is connected to.
Note: Only changes to the COM port selection can be made in this dialog
box. Since the utility only monitors the Positive UPS signals, the
other settings are fixed.
Uninstalling
To unistall the utility:
1. Exit the Power Monitor program.
2. Open the Windows Start menu.
3. Choose Programs
→ Power Monitor → Uninstall Power Monitor.
