Camera Power
The Prosilica GX camera family supports a wide input power voltage range. The
camera will not power in reverse polarity. Exceeding the voltage range specified
below will damage the camera.
Isolated IO GND
This connection provides the user ground reference and return path for the
In
2
,
Out 3
,
and
Out 4
. It is also recommended that the ground wiring be physi-
cally close to the used
In/Out
to prevent parasitic coupling. For example, a
good cable design would connect the required signal on one conductor of a
twisted pair and the
Isolated IO GND
on the second conductor of the same
twisted pair.
RxD RS-232 and TxD RS-232
These signals are RS-232 compatible. These signals allow communication from
the host system via the Ethernet port to a peripheral device connected to the
camera. Tie RS-232 ground to
Camera GND
to complete the RS-232 circuit.
Isolated Out Power
The
Isolated Out Power
connection provides power for isolated signals
Out 3
and
Out 4
. The voltage requirement is 5–24 V DC. The current requirement for
this supply is a function of the optical isolator collector current and the number
of outputs used in the system.
Isolated Out Power
wiring should be physically
close to
Out 3
/
Out 4
wiring to prevent parasitic coupling.
Caution
5–24 V. 12 V nominal.
Note
A 12 V power adapter with Hirose connector can be
ordered from AVT:
•
AVT P/N 02-8003A North America Supply.
•
AVT P/N 02-8004A Universal Supply.
