5.4.6 Wiring the Ethernet interfaces GBIT 1 and GBIT 2
The two GBit Ethernet interfaces facilitate fast output of images to a special PC which is also
equipped with two GBit Ethernet interfaces.
Connecting the GBIT 1-ETHERNET and GBIT 2-ETHERNET interfaces
¾ Connect the ICD890 Camera directly to the Ethernet card of the PC (point-to-point
connection) using the crossover cables no. 6029775 (see Tab. 5-10, page 63) .
- or -
Connect the ICD890 Camera to the GBit Ethernet network using the standardized data
cables (patch cables) no. 6029776.
5.4.7 Wiring the switching inputs IN 1 and IN 2
The reading pulse sensor is connected via the digital switching input IN 1.
The incremental encoder is connected via the switching input IN 2. Fig. 5-8 shows the wiring
of switching input IN 1 as an example. Tab. 5-15 contains ratings for both inputs.
Connecting the switching inputs IN 1 and IN 2
1. Connect the reading pulse sensor (photoelectric reflex switch) to switching input IN 1,
as shown in Fig. 5-8.
2. Connect the incremental encoder to switching input IN 2, as shown in Fig. 5-8.
3. For power supply via the ICD890 Camera, additionally establish connections between
SGND and GND in the connector of the connection cable.
