5.4 Ground connection
►
To ensure the protection of the device against electrical interference, the
housing must be connected to GND (e�g� to the ground of the vehicle)�
►
Ensure a well-conductive connection�
5.5 Ethernet interface
►
Use a shielded CAT5 cable�
STP, shielded twisted pair, to EIA/TIA-568�
Max� length 25 m
The max� cable length depends for example on the bus topology, the
selected operating mode (10/100 Mbits/s) or the quality of the connectors�
►
Use screened connector housings and connect the screen of the Ethernet
cable to the connector housing�
►
Do not lay the Ethernet cable in parallel to live cables�
Interference due to external influences
Faulty or insufficient radio interference suppressors in other electrical
equipment, such as inverters or generators, as well as voltage fluctuations
when switching on/off electric loads may lead to problems with the data
transmission�
5.5.1 Ethernet cameras
The device supports ifm Ethernet cameras (e�g� O2M110) firmware 5�1001 or
higher�
Network example
(→ 3.1 Application example)
5.6 Analogue video inputs
►
When using the analogue video inputs, please provide all connection cables
with ferrite sleeves�
Recommendation: Impedance 321 Ω (100 MHz)
The ferrite sleeves ensure CE/E1 conformity and suppress conducted
interference�
