The No Read output activates when a code signaled by the presence sensor is not
decoded.
The Right output is used to signal the presence of a right code, thus a good decode
condition.
All outputs are level or pulse programmable: a 50 ms pulse is generated in the
second case. Further programming information is supplied in the WinHost Help File.
These outputs are created using optoisolated Darlington drivers and supply both the
collector and emitter in output, allowing both loads referenced to ground and to the
power supply to be driven.
The electrical features are given below:
Collector-emitter voltage 30 V Max.
Collector current 130 mA Max (pulsed).
Saturation voltage (VCE) 1 V at 10 mA Max.
Maximum power dissipation 90 mW at 50 °C (Ambient temperature).

When the load is powered by an external power supply, the voltage must be less
than 30 V. The limit requested by the maximum power dissipation is more important
than that of the maximum collector current: if one of these outputs is continuously
driven, the maximum current must not be more than 40 mA although 130 mA may be
reached in pulse conditions.
