c
Monitor connector — Connect a video monitor to this 15-pin
HD connector for buffered, high resolution video loop through.
d
RS-232 connector — Connect a serial communications device
to this 3.5 mm, 3-pole captive screw connector for bidirectional
RS-232 communication. Wire the connector as shown in figure 2-4.

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

N 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.
