Inputs (TP) connectors — Connect the TP outputs of compatible MTP or VTT
transmitters to these RJ-45 female connectors.
C Do not connect this device to a computer data or telecommunications
network.
N You must configure the switcher for the appropriate content on the audio/
RS-232 wire pair (pins 3 and 6) for each TP input. See “Defining the Audio/
RS-232 wire pair“ in chapter 3, “Operation”. You can also use SIS commands
(chapter 4, “Programmer’s Guide”) or the Windows-based Control program
(chapter 5, “Matrix Software“).
N For best results, use a combined cable length of at least 50’ (15 m) between the
transmitter and the receiver on the MTPX output.
N RJ-45 termination with CAT 5, CAT 5e, CAT 6, or CAT 7 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.
N For low resolution MTPs (S-video and composite video) on the TP inputs, the
MTPX Plus audio circuits are only compatible with the newer generation, mono
audio models. See the MTP transmitter/ receiver to determine which MTP
models you have.
Figure 2-4 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, 6, or 7 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 568A 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.
