9H.264 Network Video Encoder
SECTION 2: INSTALLATION AND SETUP
2. Strip 1/4” of insulation from one device’s signal and ground wires and insert them into the lower terminal block in the DO ch
1 and DO GND pin locations, respectively.
3. Strip 1/4” of insulation from another device’s signal and ground wires and insert them into the lower terminal block in the DO
ch 2 and DO GND pin locations, respectively.
2.4.4 RS-485 device connection
The encoder provides one RS-485 interface connection. The wiring signal polarity and ground to the lower terminal block are
shown in the schematic below.
RS-485 device wiring schematic
To connect an RS-485 device wiring to the encoder:
1. Route wiring from the RS-485 device interface to the encoder.
2. Strip 1/4” of insulation from DATA+, DATA-, and GND wires from the device and insert them into the lower terminal block
RS-485 D+, RS-485 D-, and RS-485 GND pins, respectively, as shown in the schematic above.
2.4.5 RS-232C device connection
The RS-232C encoder interface can be connected to some devices, such as a Point of Sale (POS) terminal. The wiring signal polarity
and ground to the upper terminal block are shown in the schematic below.
