Operation with PC

The Evaluation Tool contains either a codewheel with 64
periods and outer diameter 28.2 mm or a 2-track linear
scale of 100 mm length with a centered index. Both targets
fit in the white plastic target holder.

The Interface Board is operated with a PC using the USB
cable and the ASSIST software.

Interface Board
The board contains several LEDs as listed below:
- PWR (red): Interface Board powered via USB
- ENC (red): Encoder active
- SYSTEM (red): Microcontroller active
- PROG (yellow): Programming of OTP (One Time
Programmable) memory is ongoing
- Signal LEDs (red): encoder output signals
The encoder signals are visualized by the signal LEDs and
can be measured on the TestPins and the Terminal Block.
