Announcing a compact, 2.4 GHz embedded telecommand module for remote switching applications.

Telecommand radio module NK-2.4Y

Circuit Design, Inc, the leading supplier of low power radio modules, has announced the release of an embedded commandante NK-2.4Y module capable of transmitting upto 8 switching signals. Holding FCC, IC, ARIB and CE certification, the user can integrate the module without need for additional radio approval.

The NK-2.4Y incorporates FHSS without need for channel selection, making it suitable for reliable operation in difficult RF environments and proximity to other 2.4 GHz W-LAN and Bluetooth devices. With CRC-16 error detection and a Hamming Distance of 6, user does not need to worry about unintended operation caused by communication errors. This allows continuous reliable communication of switching signals in a safety critical environment without too much concern on RF conditions.

The NK-2.4Y consumes an average current consumption of only 3 mA during transmit (input mode) allowing portable handheld operation. Feedback reception is available to the user via a LINK terminal output pin to constantly monitor communication link.

The NK-2.4Y, requiring only minimal components for interface and the option of an onboard antenna allows existing user systems to be configured to transmit wireless signals easily. An ID system combined with the frequency hopping function used by the NK-2.4Y can allow multiple user systems to operate in the same area.
