***DUE TO THE SMALL PACKAGING AND HIGH SPEED OF THE GC CAMERAS, SPECIAL
CARE IS REQUIRED TO MAINTAIN A REASONABLE OPERATING TEMPERATURE. IF THE
CAMERA IS TO BE OPERATED IN A WARM ENVIRONMENT, IT IS SUGGESTED THAT THE
CAMERA BE MOUNTED ON A HEAT SINK SUCH AS A METAL BRACKET AND THAT
THERE IS SUFFICIENT AIR FLOW.

Item : GIGABIT ETHERNET PORT
This port conforms to the IEEE 802.3 1000BASE-T standard for Gigabit Ethernet over copper.
It is recommended that CAT5E or CAT6 compatible cabling and connectors be used for best
performance. Cable lengths up to 100m are supported.

Figure 3. General Purpose I/O Pin out. Camera
rear view. 12 Sync Output 2 – non-isolated
The General Purpose I/O port uses a Hirose HR10A-10R-12PB connector on the camera side.
The mating cable connector is Hirose HR10A-10P-12S. This connector can be purchased from
Prosilica or from http://www.digikey.com.
See Addendum for more detail.
DO NOT EXCEED 5.5V ON SIGNAL INPUTS UNLESS OTHERWISE
INDICATED. SYNC INPUT 1 CAN BE DRIVEN FROM A HIGHER VOLTAGE IF
A CURRENT LIMITING RESISTOR IS USED TO LIMIT THE CURRENT TO
LESS THAN 10 MILLIAMPS.
12V Power and Power Ground
To operate the camera 12V Power with suitable current capacity (see specifications) must be
provided on Pin 2 and the Power Ground on Pin 1.
A cable assembly providing this power can be ordered from Prosilica (Prosilica P/N 02-8003A
for North America or Prosilica P/N 02-8004A for a Universal supply).

Sync Input 1 and Sync Input 2
These input signals allow the camera to be synchronized to some external event. The camera can
be programmed to trigger on the rising edge, falling edge, both edges or level of this signal. The
camera can also be programmed to capture an image at some programmable delay time after the
trigger event.
Sync Input 1 is isolated and should be used in noisy environments to prevent false triggering due
to ground loop noise. Sync Input 2 is non-isolated and can be used when a faster trigger is
required and when environmental noise is not a problem.
Sync Output 1 and Sync Output 2
These signals only function as outputs and can be configured as follows:
Exposing Corresponds to when camera is
integrating light.
Trigger Ready Indicates when the camera will accept a
trigger signal.
Trigger Input A relay of the trigger input signal used
to “daisy chain” the trigger signal for
multiple cameras.
Readout Valid when camera is reading out data.
Imaging Valid when camera is exposing or
reading out.
Strobe Programmable pulse based on one of the
above events.
GPO User programmable binary output.
Any of the above signals can be set for active high or active low.
Sync Output 1 will require a pull up resistor of greater than 1Kohm to the user’s 5V logic supply.
Sync Output 1 is isolated and should be used in noisy environments. Sync Output 2 is non-
isolated and can be used when environmental noise is not a problem and when faster response is
required.
RS-232 RXD and RS-232 TXD
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. Note that these signals are
not isolated and therefore careful attention should be used when designing cabling in noisy
environments.

Isolated Ground
Isolated Ground must be connected to the user’s external circuit ground if Sync Input 1 or Sync
Output 1 is to be used.
Signal Ground
Signal Ground must be connected to the user’s external circuit ground if Sync Input 2 or Sync
Output 2 is to be used or if the RS-232 port is to be used. Note that Signal Ground is common
with Power Ground however it is good practice to provide a separate ground connection for
power and signaling when designing the cabling.
Video Iris
This signal can be used to drive the video input of a video iris lens. See Addendum.
DNC
These signals are reserved for future use and should be left disconnected.
