Technical Specifications

-40° C to +70° C (-40° F to 160° F).

Operating Temperature Range:

100% Relative Humidity

Humidity Range:

5.125 in(H) x 3.375 in(W) x 0.437 in(D)

Physical Dimensions:

CASI-RUSCO recommends Belden 8725 (

Maximum Cabling Distance:

or equivalent). Maximum recommended distance from the micro to the

reader is 300 feet. With a junction box or amp card, the maximum

distance is 1000 feet. Using smaller gauge wire will result in shorter

maximum distance. One end of the cable shield must be grounded at the

microcontroller, using grounding posts provided inside the cabinet. The

other end must be floated at the reader. This method of grounding

ensures a low impedance shunt path for any high frequency noise

induced on the data or power lines to the reader.

: Use shielded twisted pair cable. No company, including

Note

CASI-RUSCO, can guarantee that data will be reliably transmitted over

long distances on unshielded cable.
