RS422, Synchronization
The RS422 connection (pins 11 and 12 of the multifunction port) can be used in either
of the following configurations:
- RS422 (half-duplex): Load user modes, sensor control and transmit measurement
results (Modbus RTU or ASCII format).
- Synchronization/triggering: Synchronization or triggering using switching signals.
Trigger, Encoder, Mode Switching
The switching inputs of the multifunction port can either be used for encoder input,
trigger input or for load previously stored user modes.
The signal levels are switchable for all switching inputs between LLL (TTL logic) and
HLL (HTL logic):
- LLL level: Low 0 V … 0.8 V, high 2.4 V … 5 V, internal pull-up/down switchable resis-
tor 10 kΩ
- HLL level: Low 0 V … 3 V, high 11 V … 24 V (permitted to 30 V), internal pull-up/
down switchable resistor 10 kΩ

Pulse duration: ≥ 5 µs
External Laser Switch-off, Optional
Externally switching off the laser is implemented as a hardware solution and is a top
priority. The laser can also be switched off by software.
This function is offered by sensors with the /SI option.
Use a serial key switch in the control circuit to switch off the laser.
With standard sensors, connecting the supply voltage activates the laser light source in
the sensor.
Wiring details are available in the operating instructions, Chap. 5.2.6.
