The Fischertechnik Interface is used for the Fischertechnik Trainingsrobot and for the Fischertechnik Computing Experimental kit.
Inputs/Outputs
The interface for the CPC (as well as newer RS232/USB versions) consists of:
- 8 single bit inputs ports (eg. for sensing when a robot-arm reached its end-position)
- 4 "bidirectional" ports (for motor control) (here "bidirectional" rather means "three-state-output" aka "forward/stop/backward")
- 2 analog inputs (eg. for temperature sensor)
Technical
Fischertechnik has built several interfaces:
- Interface for Commodore 24pin User Port (used on C64/VIC20)
- Interface for one-directional 25pin printer port (used on PCs) (this might have been also used by CPC...? if so, with 34pin/36pin connector, of course)
- Interface for RS232 port (used on PCs) (9600 baud, 8bit, no parity, 1 stopbit)
- Interface for USB port (used on PCs)
Parallel Printer Port Interface
Designed for one-directional printer ports: Data is read/sent via Pin11/Pin4 (which data is to be transferred is selected via the other DATA lines) (details on how the data is transferred exactly are unknown?).

The parallel fischertechnik interface has a 20pin (or 10pin) cable (the 10pin cable was used in early commodore versions, the 20pin variant was invented to simplify printer-port connections, which have GND on each 2nd wire). The various supported computers have different pin-outs: 24pin Edge (C64/VIC20), 25pin DSUB (PC/Amiga/Atari), 34pin Edge (CPC464/CPC664), or 36pin Centronics (german CPC6128). To solve that, some cables have a N-pin connector on a 20-pin cable. Others have a 20-pin connector, with additional 20-pin to N-pin adaptor.
