HF-17763
PROJECT: HF-17763
DESCRIPTION: HEX Keyboard
BRAND: Chinese People's Republic
STATUS: u
PROJECT START DATE:
LOCALISATION: various digital projects
DOCUMENTATION: nil
PCB: TPD57763
DIMENSIONS: 43 x 39 mm
CONNECTOR: goldpin 1x8 (M)
16-button keyboard, detachable, tested as local keyboard with various digital systems without built-in local keyboard like HF-6050, HF-6128, HF-6158 etc...
There is similiar model HF-17966 but layout is not compatible, with telephone type buttons A, B, C, D, *, #. THOS-1 Operating System can accept both these types, because there is EEPROM configurable switch for separate drivers (in fact only keyboard decoding table is switched).
For ad-hoc connections cable HF-70108 can be used (2x8 goldpin F<->F, 12.5 cm length).
Third HEX keyboard is also HF-17597 but not tested with digital systems yet. There was another idea behind it. I developed demultiplexer module HF-1460 for this project and it was used as fixed keyboard for other equipment.
