TP cable termination

NRJ-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.

NBy 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.

to this RJ-45 female connector on the transmitter.

CDo 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.

NEnhanced 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.
