NOTE!
The short-circuit / reverse polarity protection of the device applies to
the operating voltage connections� A short circuit between operating
voltage VBB
X
and USB / audio / video might cause damage to the
device�
►
Lay supply and signal cables away from the device using the shortest possible
route�
►
Provide all outgoing cables with a strain relief 200 mm behind the cable entry�
Maximum cable lengths:
● USB ≤ 1.8 m
● Ethernet ≤ 25 m
● Video ≤ 30 m
● Audio ≤ 30 m
Minimum operating quality audio / video:
There might be interference to audio/video circuits in the vicinity of strong HF
sources� This may result in audible and visible distortion�
Minimum operating quality of the display:
Strong HF sources in the proximity may interfere with the display� This may cause
interference with the entire visualisation�
5.5 Operating voltage and fuses
►
The individual electric circuits must be protected in order to protect the whole
system�Automotive spade-type fuses are recommended�
