Unit connectors

Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet. Using

shielded cables is recommended.

Power connector - Mini DC connector. 5.1V DC, max 3.6W. See product label for

connection.

Audio in - 3.5mm input for a mono microphone, or a line-in mono signal (left channel is

used from a stereo signal).

Audio out - Audio output (line level) that can be connected to a public address (PA) system

or an active speaker with a built-in amplifier. A pair of headphones can also be attached. A

stereo connector must be used for the audio out.

10 pin I/O terminal connector block

Pin Function Description

1 Output A On the external device output terminals (A and B), there is

no distinction between positive and negative (+ and -). The

terminals use a photocoupler and are electrically isolated

from the other internal circuitry.

The maximum load should not exceed 100mA and the max-

imum voltage should be not more than 50V DC. Note: Con-

necting AC to the output will damage the unit.

2 Output B

3 Digital Input 1

Photocoupler Anode (+)

Photocoupled Input 1. Electrically isolated from the chassis

and connectors, this input can be supplied from an external

DC voltage or the DC Power Input/Output on pins 9 (DC+)

and 10 (GND).

4 Digital Input 1

Photocoupler Cathode (-)

5 Digital Input 2

Photocoupler Anode (+)

Photocoupled Input 2. As above.

6 Digital Input 2

Photocoupler Cathode (-)

7 RS-485-A (non-inverting) A half-duplex RS-485 interface for controlling auxiliary

equipment.

8 RS-485-B (inverting)

9 DC+ Power Output This can drive the photocoupler inputs or other equipment.

The output voltage level is 3.0 V. A maximum current of

100mA can be sourced from the DC output.

10 GND Ground
