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 16. Connecting to the LAN Port
RS-232 and 12 V Power Connector — This 5-pole captive screw
K
connector 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
Remote Configuration and Control
+12 V Output Power — 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. Connect the 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 carries
M
balanced and unbalanced mono audio. It contains the following ports:
Ref — The Ref line level output carries only the USB
•
communications audio.
Aux — The Aux line level output carries only the Mic/Line input
•
signal.
To wire an individual device to the Aux output, use one of the provided
3-pole captive screw connectors.

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