APPENDIX 1
Troubleshooting
For best results always make certain you have the latest firmware.
Problem
Solution
1. No Video Signal.
a. Check that the power plug is properly inserted into a functioning
power outlet.
b. Make certain source is on.
c. Verify pin-out of connector at each end.
d. If used in electrical noisy environment shielded CAT cable may be
required.
e. Verifying routing is correct
2. LED is not lit
a. Check to see if Wall supply is plugged into wall outlet.
b. Make certain wall outlet has power.
3. No Dolby® Surround Sound
a. Make certain the proper EDID from a Dolby® capable receiver unit is
learned. Note this could affect non-Dolby® devices from playing
sound if the source outputs Dolby®.
4. LEDs on HDBaseT cards
alternating
a. Pull out all cards and reseat each card one by one until defective card
is found. The pattern signifies the backplane bus cannot communicate
and something is tying the bus up.
5. RS-232 commands not working
a. If you are using HyperTerminal to test, try to use Hercules as it can
send the commands in one shot vs. typing it in. The speed at which
the commands are sent could affect operation.
b. Check cabling for RX and TX being swapped.
c. Check baud rate settings
6. Intermittent Noise in image
a. Exceeding recommend distance relative to cable specification
b. Use shielded cable. Sometimes external devices like radio
transmitters can interfere with HDBT signals. Even though the
HDBaseT will work with non-shielded cabling we recommend its
usage for best performance.
1. All transmission distances are measured using West Penn cable as per Appendix 4. The transmission distance is
defined as the distance between the video source and the display.
2. To reduce the interference among the unshielded twisted pairs of wires in UTP cable, you can use shielded STP cables
to improve EMI problems, which is worsen in long transmission.
Warning: Do not plug RJ-45 HDBaseT output to non-HDBaseT complaint devices or damage
may occur to either product.
