The detection zone of the CR1 can be increased by use of the CR1-MS. The highest detection probability is achieved if the aerial detection zones are set to overlap by suitable placement of the two vertical aerials (e.g. using loops facing one another). Alternatively the two loops can be laid or fixed side by side to increase the size of the detection zone. The additional aerial does not affect the speed of reading tags. Reading ranges vary with the type of tag used, please refer to the Census® Products Matrix for further information.

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.). MatchMaker reader firmware enables tag pairing.
