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
