40 Troubleshooting and repair Welch Allyn VSM 300 Series
Here, the serial port (Communications Port) is configured to COM1 and the Keyspan
USB adapter is configured to COM4.
If the com port cannot be found in the Settings dialog, use the Device Manager to
configure the port.
To open the Device Manager
1. Start > right-click My Computer > Properties > Hardware >Device Manager.
2. Click Ports (COM & LPT) to expand the list.
Note
If Log I/O to file is enabled, the utility captures all communications between the
VSM and the utility in the file io.log. This file continues to grow until the
communications link is broken, because the utility is continuously checking for the
presence of the VSM.
The utility overwrites io.log each time the service utility is started.
Note
If the utility displays “VSM3 not responding”, cycle the power to the monitor.
