B. Application Errors
•
Check that the proper port is selected.
To achieve a link between the PC and the device, the LED of the correct
port must be illuminated.
•
Connect the devices directly to the PC.
If the device does not properly respond when connected directly to the
PC, the device may be damaged, not the F1U123 switch. Consult with the
manufacturer’s tech support for assistance.
•
Try rebooting the computer.
By rebooting, the operating system checks the ports for the presence of
the device. Make sure the correct port is selected so that the drivers are
loaded, and the device is fully operable.
•
Not enough power is being supplied to the switch.
The F1U123 does not require power in normal instances. However, some
parallel port devices and computers do not provide enough power to the
switch. Therefore, an optional power adapter must be used. We
recommend using Belkin part number F5B001-PWR. It is a special 7VDC
200mA power supply, and simply plugs into the power connector on the
side of the F1U123 switch. Use of other power supplies providing more
than 7VDC will significantly compromise the life of the switch.
