Introduction

This chapter provides information on how to configure the FX9500 RFID Reader Digital Inputs and Outputs.

Digital Inputs

The digital inputs (DIN1 - DIN4) can be used as general purpose inputs or to trigger the reader for tag reading.
Unused or open digital inputs are floating inside the reader.
To activate the input, pull it low (0 Vdc) with an external device or connection to ground that can sink 2.5 mA. No
voltage higher than +24 Vdc or lower than 0 Vdc should ever be connected to the input. See
5-2 for an example of a typical motion sensor installed as a tag read trigger device.

Digital Outputs

The digital outputs (DOUT1 - DOUT4) can be used as general purpose outputs, to indicate tag reading activity, or
to indicate the reader is transmitting (RF On). Digital outputs can be pulled high.
No voltage higher than +40 Vdc or lower than 0 Vdc should ever be connected to a digital output. The reader
activates the output by pulling it low (0 Vdc) and can sink current such that power dissipation < 1W.
