5.4.3 Wiring CAN interface
To wire and configure the bar code scanner's CAN interface for use in the CAN-
SENSOR-network, see the operating instructions "Using the CAN Interface“ (no.
8009180, English).
5.4.3 Wiring Ethernet interface
Aux and host interface communication can also be executed in parallel via the Ethernet
interface.
The Ethernet interface has an auto-MDIX function. This automatically sets the speed
and any cross connection that is required.
5.4.4 Wiring switching inputs
If the RFH620 reading process should be triggered by an external sensor, the reading
pulse sensor is connected to the "Sensor 1" switching input.
Switching behaviour
Power fed to the input opens the internal reading gate of
the RFH620. (Default setting: active high; debouncing:
max. 30 ms (standard))
