Read disable input
The reading of the TRANSIT Ultimate can be stopped with the read disable input (RDIS). This input is commonly used in
combination with a sensor (e.g. inductive loop) that detects the presence of a person or vehicle. Use a potential-free
contact (relay) to connect the internal 5V to the RDIS input. Leave open or unconnected when reading should be
enabled.
