GIGABIT ETHERNET PORTS

These ports conform 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. For higher bandwidth requirements, both
ports can be used in a link aggregation group (LAG) configuration.

GENERAL PURPOSE IO PORT AS SEEN FROM

BACK OF CAMERA

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
AVT Canada Inc. or from http://www.digikey.com. An open-ended cable assembly can also be
ordered from AVT Canada Inc. (Part number 02-6033A).

See Addendum for more detail.

POWER GROUND

This is the main ground of the camera circuitry and will be the return path for the external power
source. This connection must be provided to operate the camera. The conductor used for this
connection must be adequate for the current consumption of the camera. For best performance
the connection for POWER GROUND should be physically close to the EXTERNAL POWER
connection.

Allied Vision Technologies (Canada) Inc.

GX1660 User Manual

EXTERNAL POWER

This connection provides the main power for the camera. The camera operates from a DC
voltage between 5V to 24V. The current capacity of the power supply can be estimated by
dividing the camera’s power requirement by the external power voltage. It is also recommended
to factor this by about 50% as follows:

Power supply current capacity = (power specification / external voltage) x 1.5

The conductor used for this connection must be adequate for the current consumption of the
camera. For best performance the connection for EXTERNAL POWER should be physically close
to the POWER GROUND connection.

SYNC INPUTS (1 and 2)

The input signals allow the camera to be synchronized to some external event. These signals are
optically isolated and require the signal common (USER GROUND). The camera can be
programmed to trigger on the rising or falling edge of these signals. The camera can also be
programmed to capture an image at some programmable delay time after the trigger event.
These signals can be driven from 5V to 24V with a current load of 5mA.

SYNC OUTPUTS (1 to 4)

These signals are optically isolated and require the user to provide a high voltage level (USER

function of USER VCC and load resistor R. An example of the functional circuit is indicated in

GX1660 User Manual

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.
Strobe Programmable pulse based on one of the

above events.
Imaging Valid when camera is exposing or

reading out.
GPO User programmable binary output.

70-0057A-A

Any of the above signals can be set for active high or active low.

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. These signals are not
optically isolated and reference power ground. If these signals are used in the system, care must
be taken to prevent ground loop problems.

USER GROUND

This connection provides the user ground reference and return path for the isolated sync in and
sync out signals. This connection is necessary if any of the isolated sync signals are to be used.
It is also recommended that this ground connection be physically close to the used sync signals
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 ground on the second conductor of the
same twisted pair.

USER VCC

This connection provides the power supply for the isolated sync out signals. The voltage
requirement is from 5V to 24V DC. The current requirement for this supply is a function of the
optical isolator collector current and the number of sync outs used in the system. See the

OUTPUT

section for more detail. To prevent parasitic coupling this connection should be

SYNC

physically close to the used SYNC OUT signals and USER GROUND.

LENS CONTROL PORT AS SEEN FROM BACK OF

CAMERA

This connector provides the signals necessary to control the iris, focus, and zoom of most
commercially available TV Zoom lenses. The camera can be configured to operate lenses with
unipolar voltage requirements of 6V up to 12V or lenses which operate with bipolar voltages
from ±6V up to ±12V. This voltage level can be controlled through software. The default
voltage will be set to 6V. The current capacity for each axis is 50mA.

CARE MUST BE TAKEN NOT TO EXCEED THE LENS MANUFACTURERS
VOLTAGE SPECIFICATION.

This connector also provides the signals necessary to operate a video auto iris type of lens.
The lens control connector is a Hirose 3260-8S3. The mating cable connector is Hirose 3240-

8P-C(50). This connector can be purchased from AVT Canada Inc. or from

http://www.digikey.com.

Cleaning the Sensor

DO NOT CONTACT CLEAN SENSOR UNLESS ABSOLUTELY NECESSARY.

Identifying Debris

Debris on the image sensor or optical components will appear as a darkened area or smudge on
the image that does not move as the camera is moved. Do not confuse this with a pixel defect
which will appear as a distinct point.

Locating Debris

Before attempting to clean the image sensor, it is important to first determine that the problem is
due to debris on the sensor window. To do this you should be viewing a uniform image, such as
a piece of paper, with the camera. Debris will appear as a dark spot or dark region that does not
move as the camera is moved. To determine that the debris is not on the camera lens, rotate the
lens independent of the camera. If the spot moves as the lens moves, then the object is on the
lens -not on the image sensor- and therefore cleaning is not required. If the camera has an IR
filter, then rotate the IR filter. If the object moves then the particle is on the IR filter not the
sensor. If this is the case remove the IR filter carefully using a small flat head screw driver.
Clean both sides of the IR filter using the same techniques as explained below for the sensor
window.

70-0057A-A

DO NOT TOUCH ANY OPTICS WITH FINGERS. OIL FROM FINGERS CAN
DAMAGE FRAGILE OPTICAL COATINGS.

Cleaning with Air

If it is determined that debris is on the sensor window, then remove the camera lens, and blow
the sensor window directly with clean compressed air. If canned air is used, do not shake or tilt
the can prior to blowing the sensor. View a live image with the camera after blowing. If the
debris is still there, repeat this process. Repeat the process a number of times with increased
intensity until it is determined that the particulate cannot be dislodged. If this is the case then
proceed to the contact cleaning technique.

Contact Cleaning

Only use this method as a last resort. Use 99% laboratory quality isopropyl alcohol and clean
cotton swabs. Dampen the swab in the alcohol and gently wipe the sensor in a single stroke. Do
not reuse the same swab. Do not wipe the sensor if the sensor and swab are both dry. You must
wipe the sensor quickly after immersion in the alcohol, or glue from the swab will contaminate
the sensor window. Repeat this process until the debris is gone. If this process fails to remove
the debris, then contact AVT Canada Inc.
