GS702 Datasheet, PDF (2/2 Pages) List of Unclassifed Manufacturers – Flexible Remote Control (FRC) Technology Transmitter

FRC CAD and Programmer features
Every FRC remote control project contains three separate CAD sections, providing data for:
- PCB key layout,
- Protocol description (with all timings specification) and
- Command Address/ Data info
Programmable parameters: Key-type (Normal, Shift or Special), Modulation type, Resonator frequency, Bit-
time, Duty factor, etc.
The implemented FRC CAD project is downloaded to the Chip Programmer and GS702 programming is
performed in an autonomous (disconnected from the PC) mode.
