Connecting electrical power to the radio link
Therefore, please observe the following instructions:
• Wherever possible, lay cables inside the vehicle, as they are better protected there than
outside.
If you do need to lay a cable outside the vehicle, ensure that it is well fastened (use additional
cable ties, insulating tape etc.).
• To prevent damage to the cables when laying them, ensure that they are far enough away from
hot or moving vehicle components (exhaust pipes, drive shafts, light systems, fans, heaters
etc.).
• Screw on the plug connections of the connecting cables to protect against water penetration
(fig. 4, page 4).
• When laying the cables, make sure:
– they are not kinked or twisted
– they do not rub on edges
– they are not laid in sharp-edged ducts without protection (fig. 3, page 4).
• Protect every through-hole made in the bodywork against water penetration, e.g. by using a
cable with a sealant and by spraying the cable and the cable sleeve with sealant.
I
NOTE
Only start sealing through-holes when you have completed all installation work on the
camera and have laid the required cable lengths.
7.2 Connecting electrical power to the transmitter module
A
NOTICE!
Make sure the polarity is correct.
VT100DIG requires a few seconds to initiate the digital wireless connection. To keep this start-up
time short, you should connect the transmitter module to an active +12 V voltage supply. If no
continuous operating voltage is available, you can connect the transmitter module to the reversing
light.
Connecting the transmitter module to a continuous operating voltage
➤ Connect the red cable of the transmitter module (fig. 6 7, page 5) to an active positive cable,
e.g. terminal 15.
➤ Connect the black cable of the transmitter module (fig. 6 8, page 5) to earth (bodywork).
➤ Connect the green cable of the transmitter module (fig. 6 6, page 5) to the reversing light.
A
NOTICE!
Always connect the green cable to the reversing light and not to a continuous
operating voltage or an active positive cable. The "pairing" is started via this cable by
engaging the reverse gear three times.
