RS422, Synchronization

The RS422 connection (Pin 11 and 12 of the multifunction port) can be used with
either of the following configurations:
- RS422 (half-duplex): Load user modes and sensor control.
- Synchronization/triggering: Synchronization respectively triggering using switching
signals.
Trigger, Encoder, Mode Switching
The switching inputs of the multifunction port can either be used for encoder input, for
trigger input or for loading previously stored user modes.
The signal levels are switchable for all switching inputs between LLL (low-voltage-,
TTL logic) and HLL (high-voltage-, HTL logic):
- LLL level: Low 0 V ... 0.8 V, high 2.4 V ... 5 V, internal pull-up 10 kΩ to 5 V
- HLL level: Low 0 V ... 3 V, high 11 V ... 24 V (permitted to 30 V), internal pull-up 10
kΩ to 24 V
Pulse duration: ≥ 5 µs
