7. Power supply
Always make sure that there is enough power to the Oyster to
avoid trouble. As with any other computer device, the Oyster
Digital receiver is somewhat sensitive to a weak power supply.
a)
The Oyster requires a 12V or a 24V DC power supply. We
recommend a 12V supply. Any voltages above 30V or any AC
voltages will destroy the receiver absolutely. This will NOT be
covered by warranty.
NOTE: +12V/24V is RED and COMMON GROUND is BROWN
b)
To interconnect the Oyster you should use cables with a
diameter of 2.5mm². Use 4mm² if the length of your cables
extend beyond 5m.
c)
Always directly connect the system to the vehicle's battery. If
you find existing power lines in the vehicles, note that they are
most often NOT sufficient to supply the Oyster.
Never ever connect the Oyster to lines of any other high power
system, such as an air conditioner, a microwave oven or
anything that is suspected of producing interference such as an
electric ignition to any kind of a gas heater. Such systems will
severely interfere with the Oyster and will disturb regular
operation.
d)
If you find a central fuse and switch unit in the vehicle, you
may connect the Oyster to it, if this unit is directly connected to
the batteries with large diameter cables (25mm² and up).
In case of any trouble try to bypass such a unit to see if it fixes
the trouble.
Any fuse along the power line should be between 10A and 20A.
