3.5.2 READ DISABLE INPUT
The reading of the uPASS Reach can be completely disabled with the RDIS input. This
input is commonly used in combination with a sensor (e.g. inductive loop) that
detects the presence of a person or vehicle. Use always a relay contact to connect
the internal 5V to the RDIS input. When the RDIS input is unused the reader is
enabled.
