ID-NET Network Termination
The network must be properly terminated by a 120 Ohm resistor at the first and
last reader of the network.
Inputs
There are two optocoupled polarity insensitive inputs available on the M12 17-
pin connector of the reader: Input 1 (External Trigger) and Input 2, a generic
input. See "Inputs" on
page 73 for more details.
The electrical features of both inputs are:
INPUT

| Min. | V
AB
| Max. I

.
Open 0 V 2 V 0 mA
Closed 4.5 V 30 V 10 mA
The relative pins on the M12 17-pin connector are:
Input Pinout
Pin Name Description
1 Vdc Power Supply input voltage +
6 I1A External Trigger A (pola
rity insensitive)
5 I1B External Trigger B (polarity insensitive)
13 I2A Input 2 A (polarity insensitive)
3 I2B Input 2 B (polarity insensitive)
2 GND Power Supply input voltage -
For Matrix 300N PoE models, the internal Digital Output circuitry is not powered and
supply power is not available to any Input/Output devices (Vdc=0). Only input device
signals can be accepted directly on the M12 17-pin connector without power.
For these models, if it is necessary to use Input/Output devices, we recommend con-
necting them through the CBX, which must be powered separately.
