6.1 Lite-Link Interface Cable
Lite-Link Interface Cable
Many manufacturers of PC software and hardware use serial (COM) port(s). It
is difficult to predict potential serial port conflicts. If the Lite-Link interface
cavle's wand tip is not flashing, ther are a few steps that can be taken in order
to potentially find the source of the problem.
·
Make sure that the Lite-Link interface cable is securely plugged in. The
Lite-Link 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 Lite-Linnk 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 comunication problems, shut down your computer
and restart if before you run the PowerWatch program.
·
Verify that your serial port settings are correct. In Windows 3.1, use the
Microsoft Diagnostics program, MSD.EXE, to find out the number of
installed serial ports in you 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 an internal modem is used, MSD may
detect the modem's serial port. This serial port cannot be directly used with
the Lite-Link.
Windows 95 users can verify port settings using Device Manager. Device
Manager is found on the Task Bar by choosing
Start, Settings, Control
Panel, Systems, and Device Manager.

·
Verify that your serial port is functioning properly. Use any standard
Windows communications program to ensure the port is functioning.
Examples include:
ProComm , Windows 3.1 Terminal or Windows 95
Hyperterminal.
Exit all programs (including PowerWatch) and connect the Lite-Link to the
