The CR1-DS-MS reader utilises two external pairs of loop aerials to enable direction sensing at ranges of up to 3 metres from each loop. Alternatively the unit can be configured to monitoring two independent wide (4-5 metre wide) doors using one controller. The final configuration is to group all four antenna together for a single detection zone. The highest detection probability is achieved if the detection zones of each of the aerial in a pair are deliberately set to overlap (e.g. using vertical loops in pairs facing one another). It is compatible with all Census® tags. The radio-frequency communications are scrambled to provide high integrity decoding, and prevent simulated tokens being used.
The CR1-DS-MS reader interrogates each loop pair in turn for the presence of tags (i.e. multiplexing). In the direction sensing case a tag moving from one loop pair to another will have its travel direction identified by the reader. The speed of reading tags is effectively halved by this mechanism.
It is important that each of the detection zones created by the loop pairs should not overlap by more than a few centimetres. If used with the Dual or Inward Twin firmware each loop pair is managed independent of the other and the data relating to tags seen in each zone is processed on a separate output port. Where detection zones overlap tags will be reported from both ports
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.).
