RS-232 connector — Connect a serial communications port to

 

this 3.5 mm, 3-pole captive screw connector for bidirectional

 

RS-232 communication. See "RS-232 connector wiring," on

 

page 2-26, to wire the connector.

 

N The RS-232 connector can also transmit one-way

 

modulated infrared (IR) signals. See "Modulated IR

 

pass through" on page 2-33.

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 568B 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.

Figure 2-20 — TP cable termination

NDo not use Extron’s UTP23SF-4 Enhanced Skew-FreeA/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

DVI 201 Tx/Rx will 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.
