TP cable termination

NRJ-45 termination with CAT 5, CAT 5e, or

CAT 6 cable must comply with the TIA/EIA T 568A or TIA/EIA T 568B wiring standard for all connections.

Figure 2-20 details the recommended termination of TP cables with RJ-45 connectors in accordance with either the TIA/EIA T 568A or the TIA/EIA T 586B wiring standard.

NTerminate both ends of both cables identically, in accordance with either the TIA/EIA T 568A or the TIA/EIA T 568B wiring standard.

NDo not use Extron’s UTP23SF-4 Enhanced Skew-Free™A/V UTP cable to link the transmitter and receiver. Skew-free A/V cable was designed for most Extron

TP transmitter/receiver applications, but the HDMI 201 Tx/Rx does not work properly with this cable.

NIn order to fit in the junction box, the TP cables and RJ-45 connectors should not have a boot installed.

NIf necessary, test for proper cable connection (output 1 to input 1, output 2 to input 2) as follows:

1. Plug both TP cables into the powered unit.

2. Momentarily connect either of the cables on the opposite end into the unpowered unit‘s “2” connector.

If the unpowered unit’s Power LED is lit, the connection is correct.

If the unpowered unit’s Power LED is not lit, unplug the connector on the unpowered end and connect the other cable to the “2” connector.
