3.5.2 DISABLED READING
AT-4 reading can be completely disabled by means of the RDIS input. This
input is commonly used together with a sensor (e.g. with a magnetic loop)
that detects the presence of a vehicle. Use a voltage-free contact to connect
the 5V to the RDIS input. When the RDIS input is open, the reader is active.
Connections:
RDIS
Disabled reader input
5V
Internal 5V
Important:
Using an external power pack for 5V can damage the reader.
