The CTA88 remote control chip application board is now available from Radiometrix. The board provides simple eight-channel digital input/output implementations of remote control functions. This can be done by using either the company's multi-channel LMT/LMR (UHF and VHF band) or its single frequency BiM (FM band) series of wireless radio modules, which are ordered separately. The board has two CTA88-000-DIL chips, a CTA88 encoder board, a CTA88 decoder board, a quarter wavelength monopole or helical antennae, four jumpers for mode configuration, DIP switches for address and frequency channel configuration, eight opto-isolated digital inputs, and eight relay outputs. The remote control chip at the core of each board is an 8bit address encoder/decoder for use with licence-exempt ISM/SRD band radio modules. It is used to set up a straightforward one-way wireless link for remote control applications. This, according to the company, requires the minimum of engineering effort and takes little time to establish. Furthermore, says the company, it does not call for any customer software input. The transmitter and receiver application boards are designed to allow easy evaluation of the remote control chip's performance and functionality in elementary jobs. The boards have compact dimensions, they measure 115x86x20mm and operate in the temperature range of -20 to +70°C.
