Application board kit for developers of simple wireless remote control
13 August 2010
Radiometrix has introduced an application board kit, which can be used to develop simple eight channel digital input output implementations of remote control functions using either a multichannel LMT/LMR (UHF and VHF band) or single frequency BiM (FM band) Radiometrix wireless radio module.
The offering comprises two CTA88-000-DIL chips, a CTA88 encoder board, a CTA88 decoder board, ¼ wavelength monopole or helical antennas, four jumpers for mode configuration, DIP switches for address and frequency channel configuration, eight opto-isolated digital inputs, and eight relay outputs.
The CTA88 chip at the heart of each board is an 8-bit address encoder/decoder for use with licence-exempt ISM/SRD band radio modules. It permits the setting up of a straightforward one-way wireless link for remote control applications. This requires the minimum of engineering effort and takes little time to establish. Furthermore it does not call for any customer software input.
