5. Troubleshooting
Make sure that all connections to the PC and peripheral equipment are solid. Reboot the
PC if any of the connections were loose as this may have caused the PC to lock up.
If the problem is related to the video, check the function and calibration by placing the
unit is Calibration mode using the switch on the sender. If the image on the display is not
centetred properly, use the LCD’s on screen display to do an Auto Adjust Image.
If the problem is with the USB devices, check the state of the LED’s on the front panel of
the each unit. These LED’s pertain to USB links. The General purpose USB (STD) link
light should be on if proper connection is made between the sender and the receiver,
Data light will light if connection to PC is made and adevice is plugged to one of the STD
USB ports on the remote unit. The DR1 and DR2 leds function when the sender is
connected to the PC and the receiver at the remote is connected to a USB device (such
as a printer) therefore link and data LEDs work together. If connection to the PC of DR1
or DR2 is verified, but the Link and Data leds are off, unplug the corresponding device
from the remote, wait 5 seconds and plug it back in.
Check the RJ45 port connections (A to A, B to B, etc), make sure they are not crossed,
loose, or disconnected. Use the following chart to narrow your attention depending on
device you are having trouble with:
Port A of the UTP carries VGA A and AUDIO signals
Port B of the UTP carries VGA B and Bi-directional RS232 signals
Port C of the UTP carries the Standard (STD) USB and the “Direct” USB port DR1.
Port D of the UTP carries the “Direct” USB port DR2
If you cannot trouble shoot the setup, please note all pertinent symptoms and make a list
of any other equipment used in the setup.
Do not open or try to repair the unit yourself. There is no customer repairable item in the
unit and you will void the warranty.
