Physical Description
CNRFT-32A/48A and CNIRT-32A/48A electronic hardware is housed in a high-impact molded plastic
enclosure (refer to figures 1 and 2 for front and back views, respectively ). The button array on the printed
circuit board is covered by a customized button panel. All button panels include custom engraving, colored
button caps, choice of button configurations, and panel finishes. Refer to the latest version of the
CRESNET II Engraving Worksheet for the wireless transmitters (Doc. 5242 and Doc. 5243) to design a
unique button panel. Omission of unused buttons is standard. A red transmit LED is located above the
button panel cover.

A standard nine-volt battery is included with all units. Access to the battery is permitted after the
battery cover, located on the underside of the unit, is removed. A sensor (photo transistor) used to
program an identity code is also located in the battery compartment.
Configuration Differences
The RF and IR one-way wireless transmitters have two different configurations based on the maximum
number of buttons available on the customized panel. They are depicted in table 1.
