7H.264 Network Video Encoder
SECTION 2: INSTALLATION AND SETUP
2.4.1 Audio in/out connections
The encoder includes an interface for a mono audio input (from a microphone) and a mono audio output (to a speaker). The audio
output is a low level signal that requires an amplied speaker (see Specications).
To connect a speaker and/or microphone to the encoder:
1. Route speaker and/or microphone wiring to the encoder.
2. Strip 1/4” of insulation from the wires speaker signal and ground wires and insert them into the lower terminal block on the
AOut and AOut Gnd pins, respectively.
3. Strip 1/4” of insulation from the microphone signal and ground wires and insert them into the upper terminal block on the
Ain and Ain Gnd pins, respectively.
2.4.2 Sensor in (DI) connection
The encoder provides two input channels for sensors. The sensors can be either voltage or relay type sensors, but not one of each.
For voltage type sensors, see Specications for allowable voltage levels. The conguration of the sensor input wiring is illustrated in
the diagrams below.
CAUTION
Do not exceed the maximum input voltage or the relay switching rate. Refer to specications in this manual
for more information.
