Camera Power
The Prosilica GT camera can be powered through the Hirose I/O port, via Pin 1
Camera GND
and Pin 2
Camera Power
, or through the Gigabit Ethernet port if
using a power over Ethernet (PoE) supported network card, switch, or injector.
Cameras powered by both the Hirose I/O port and the Gigabit Ethernet port will
use the power provided by Hirose I/O port only.
Pin 2,
Camera Power,
supports an input voltage range of 7–25 VDC. The camera
will not power in reverse polarity. Exceeding the 25 V will damage the camera.
RxD RS-232 and TxD RS-232
These signals are RS-232 compatible. These signals are not optically isolated.
Tie RS-232 ground to
Camera GND
to complete the RS-232 circuit. Communica-
tion is at 11520 baud.
Input triggers
Input triggers allow the camera to be synchronized to an external event. The
camera can be programmed to trigger on the rising edge, falling edge, both
edges, or level of the signal. The camera can also be programmed to capture an
image at some programmable delay time after the trigger event.
In 1 – Non-isolated
In 1
is not electrically isolated and can be used when environmental noise is
inconsequential and faster trigger response is required. The required trigger
signal is
low voltage TTL 3.3 V.
Tie trigger ground to
Camera GND
to complete
the trigger circuit.
Note
A 12 V power adapter with Hirose connector is available for pur-
chase from Allied Vision:
