Telecommand radio module The NK-2.4Y is an embedded input / output radio module which operates in the 2.4 GHz band. In spite of its small size and low power consumption, it achieves a communication range of 100 m (line of sight). Our original frequency hopping protocol allows multiple modules to be used in one area simultaneously without concern about radio channels. With a fast input-output response time of 20 ms, a maximum of 8 switch inputs / outputs can be transmitted. Regarding an antenna, customers can select either internal PCB antenna or external antenna specified by Circuit Design. Link signal output shows connection status, which helps the user to stay within the signal coverage area. ・ FCC, ISED, CE, UKCA and ARIB conformity ・ Module can be set to either input or output mode. ・ CRC-16 error detection Achieves a Hamming distance of 6 to minimize malfunction ・・ ・ Transmission of max 8 switching signals by connecting simple external circuitry ・ Low current consumption ・ Rapid two way communication for confirmation of communication link status. ・ 1:1 communication only ・ Frequency hopping allows multiple systems in one area without concern about channel management Applications ・ Remote tail lifts on trucks. ・ Remote control of care lifts on welfare vehicles ・ Shutter open and close Applicable standard FCC Part 15 / ISED RSS-247 ARIB STD-T66 / EN 300 440 Communication method Communication mode 1:1 (Input mode: Output mode) Operating temperature Internal pattern antenna or specified external antennas Supply voltage Input / Output response Hamming distance Soldering conditions Half duplex (for ACK purposes only) Communication range Hand soldering (Soldering iron temp: 350 C within 3 sec) Supply current Input voltage range Input voltage threshold Input mode Low Level: 0.4 V (max) High Level: 1.7 V (min) Output mode Supply current When linked: 7 mA ave.
