The CR1-DS1 reader has split transmit and receive functions to enable direction sensing. The CR1-DS1 reader utilises a single external loop aerial and a minimum of two strategically placed receiver pods to enable direction sensing at ranges of up to 3 metres. The CR1-DS1 is used in preference to the CR1-DS in noisy environments, or where adequate loop separation is impossible. It is compatible with all Census tags®. The radio-frequency communications are scrambled to provide high integrity detection, and prevent simulated tokens being used.
The CR1-DS1 reader interrogates the detection zone of each pod in turn for the presence of tags (i.e. multiplexing). A tag moving from one receiver pod detection zone to another will indicate the direction of travel. The speed of reading tags is effectively halved by this mechanism.
The CR1-DS1 reader can be used with a single receiver pod as an enhanced CR1 reader in those circumstances where the CR1 (with external loop) must be installed where there are significant and unavoidable noise signals. The geometric positioning of the pod can minimise noise pickup. The unit can also be used to change the shape of the detection zone.
The receiver pods for CR1-DS1 are SL4 (internal use) and SL5 (outdoor use).
All CR1 readers provide Wiegand or Clock & Data, as well as RS232 output. Advanced features include local alarm outputs, print option and an optional counter display (See IDN1, EDN1 for further information.).
