Thank you for purchasing this product. For optimum performance and safety,
please read these instructions carefully before connecting, operating or adjust-
ing this product. Please keep this manual for future reference.
SURGE PROTECTION DEVICE RECOMMENDED
This product contains sensitive electrical components that may be damaged by
electrical spikes, surges, electric shock, lightning strikes, etc. Use of surge
protection systems is highly recommended in order to protect and extend the life
of your equipment.
SAFETY AND NOTICE
1. The transmission distances of HDMI over UTP cables are measured using
TE CONNECTIVITY 1427071-6
2. EIA/TIA-568-B termination (T568B) and “AWG24/1 solid wire” for CAT
cables is recommended for best performance.
3. DO NOT use 568A/568B standard mixed CAT cable (cross-over cable)
because there are 2 pairs swapped, this will make POE OVER-CURRENT
and damage POE components. Please use straight-through CAT cable (both
RJ45 headers are 568A or 568B standard).
4. It is recommended that power up the device after connections of source, sink
and CAT cable.
5. To reduce the interference among the unshielded twisted pairs of wires in
CAT cable, do not run HDBaseT / Zone Cat5e/6/6a cabling with or in close
parallel proximity to mains power cables. Shielded CAT cables can be used
to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the CAT cables has the major effect on how long the
transmission limit can achieve and how good is the received picture quality,
the actual transmission range is subject to one’s choice of CAT cables.
7. Do not substitute or use any other Power Supply other than the
enclosed unit, or a TLS electronics GmbH approved Replacement Part.
Doing so will void the warranty and potentially expose the user to
dangerous voltages resulting in an electrical shock.
8. Do not disassemble the device for any reason. Doing so will void the manu-
facturer’s warranty. Also, our unique case is an integral part of the design of
this unit and is responsible for cooling and circuitry shielding. Any modifica-
tions to this case will potentially cause malfunction and product failure.
9. Do not expose the device to water, moisture, or liquids. Possible electric
shock may result as well as failure of the unit to operate.
