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

External Laser Switching
The sensors of the scanCONTROL 26xx/SI, scanCONTROL 29xx/SI series offer this
function.
Use a serial key switch inside the control circuit to switch off the laser.
You will find details for the wiring in the instruction manual, Chap. 5.2.6.
