APPENDIX 1 Troubleshooting
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. If run is longer than 330ft or unit is in long range mode the signal will
be limited to 24bit color depth. Verify deep color is not turned on source
equipment.
2. LED is not lit
a. Check 24v power supply is plugged in.
b. Check to see if Wall supply is plugged into wall outlet.
c. Make certain wall outlet has power.
3. LAN POE not working
a. Verify the POE switch total power is adequate. Some POE switch
power ratings cannot supply the full 15.4 watts per port. Make certain
to multiply the amount of ports by 15.4watts and compare to the
switches total spec.
b. POE from Transmitter will only work on the non-amplifier versions
c. POE on receiver is not available for amplifier model.
4. IR not working
a. Verify using proper emitter or receiver to specifications outlined. Use
Aurora branded accessories for best results.
5. DXE-CAT-RX3 is very warm
a. This is normal. HDBaseT receivers do run very warm when signal is
applied. You will note the transmitter runs much cooler.
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 DXE-CAT series will
work with non-shielded cabling we recommend its usage for best
performance.
7. IR port on RX side does not work
with some devices
a. The IR on the RX side is limited to 38kHz so only remotes with 38kHz
carrier will work. Keep in mind some remotes between 36kHz-40kHz
may work. The TX side which is local to the processor will work with
carrier frequencies from 30kHz to 100kHz.
8. Need to update firmware
a. Use LXupdate found on the Aurora website.
9. Cannot ping IP address
a. Make certain only 1 LAN port is connected to same switcher. The DXE-
CAT LAN ports are a switch not a router.
b.
Make certain unit is an “C” version and has the IP option.
10. RS-232 is not communicating
a. Verify baud rate setup is correct on each port.
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 compliant devices
or damage may occur to either product.
