5.3.3
“AUX” data interface
General requirements of the data interfaces
The AUX data interface (auxiliary data interface) of the camera system can be operated as
an RS-232 design or re-directed to the Ethernet interface.
The following table shows the recommended maximum cable lengths depending on the
interface design and the data transmission rate.
Interface type
Data transmission rate
Distance to the target computer (host)
AUX (RS-232)
Up to 19.2 kBd
38.4 kBd ... 115.2 kBd
max. 10 m max. 3 m
Ethernet
10/100 Mbit/s
max. 100 m
Gbit Ethernet
100 Mbit/s ... 1 Gbit/s
max. 100 m
1) With the corresponding cable termination as per specification
Tab. 18: Maximum cable lengths
▸
Use shielded data cables (twisted pair wires).
▸
To avoid interference factors, do not lay data cables over a longer route in parallel with
voltage supply cables and motor cables, e.g., in cable channels.
Wiring the AUX data interface
NOTE
Damage to the interface module
If the AUX data interface is wired incorrectly, then electronic components in the camera
system could become damaged.
Measures
▸
Wire the data interface correctly.
▸
Carefully check the wiring prior to switching on the camera system.
▸
Connect data interface to the PC in an EMC-compliant manner with a shielded cable.
Please note the maximum cable lengths (see above).
▸
Wire the RS-232 version as follows.
