Pair Wires
T568A
RJ-45
A cable that is wired as T568A at one end
Connector
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
Figure 8. Connecting to the LAN Port
RS-232 and 12 V power connector — This 5-pole captive screw connector
K
contains:
RS-232 port — For serial RS-232 control, connect a host computer
•
or control system to the Tx, Rx, and G pins of this connector (see
Connecting for Remote Control
+12 V output power — If desired, connect a device requiring
•
DC power (such as a digital I/O device that illuminates LEDs for a
microphone or switch plate) to the + and – pins of this connector.
Digital I/O connector — This 5-pole, 3.5 mm captive screw
L
connector contains two digital input ports and two digital output ports with
a common ground pin. These ports are for use with microphones that have
logic inputs or outputs for LED and mute control. The input port may be
used to trigger mic mute, group master increment and decrement, or audio
preset recall, while the two output ports provide tally back to indicate status.
The digital input ports are labeled I1 and I2. The output ports are O1 and
O2. The middle pin, labeled G, is the ground. You can wire inputs to pins
I1 and I2 and outputs to pins O1 and O2. Connect the ground wires of all
devices to the G pin. See the illustration at right to wire this connector.
Ref and Aux connector — This 5-pole, 3.5 mm connector is for balanced
M
and unbalanced audio. It contains the following ports:
Ref — Connect a line output to the +, –, and ¤ (ground) Ref
•
pins of this connector to use as the reference for acoustic echo
cancellation. Far end audio from the USB Communications input is
routed to the Ref output for connection to an external DSP matrix
processor with AEC.
Aux — If desired, connect an amplifier or other audio output device
•
to the (ground) and the Aux + and – pins of this connector. The Aux
output carries the Mic Input signal when local sound reinforcement is
required.
To wire an individual device to either of these ports, use one of the provided 3-pole
captive screw connectors.
To wire both a reference and an auxiliary output to the REF/AUX connector, use a
5-pole captive screw connector wired for balanced output (see
with the ground wires of both the reference and auxiliary devices connected to the
center (ground) pin.

A cable that is wired the same at both ends
is called a "straight-through" cable, because
no pin or pair assignments are swapped.
