By default, the RS-232 portion of the TP link is

unidirectional only from the transmitter to the receiver.

If there is only one receiver in a system, a jumper

within the receiver allows the RS-232 communication

to be bidirectional. Refer to the

MTP 15HD RS Series

manual.

e

Pre-Peak switch —

The Pre-Peak switch alters the TP signal

output to correct for long cable runs. See the table on page 1-4

for suggested switch settings based on the transmitted video

format and transmission distance.

f

Transmitter Output connector — Connect one end of a TP cable

to this RJ-45 female connector on the transmitter.

C

Do not connect this device to a computer data or

telecommunications network.

Connect the free end of the same TP cable from the transmitter

to the receiver’s Input RJ-45 female connector.

See “TP cable termination” on the next page to properly wire the

RJ-45 connectors.

TP cable termination

N

RJ-45 termination with CAT 5, CAT 5e, or CAT 6

cable must comply with the TIA/EIA T568A or

TIA/EIA T568B wiring standards for all connections.

RJ-45 termination with Skew-Free A/V UTP cable must

comply with TIA/EIA T568A only.

Figure 2-5 shows the recommended termination of TP cables in

accordance with the TIA/EIA T568A or TIA/EIA T568B wiring

standards. You can use either standard with CAT 5, 5e, or 6

cable, but use the same standard on both ends of the cable.

Enhanced Skew-free A/V cable is not recommended

for Ethernet/LAN applications. This cable is specially

designed for compatibility with Extron’s Twisted Pair

products that are wired using the TIA/EIA 568 A

standard.

The green, brown, and blue pairs of this cable have

virtually identical lengths and should be used to

transmit the RGB signals.

The orange pair of this cable has a different length and

should not be used to transmit the RGB signals.
