Introduction
Introduction User's Manual

1.2 Technical Details
The PC_EYE®2+ is intended for applications where up to four parallel
channels are digitized, such as RGB data with additional alpha channel or
four monochrome synchronous cameras are used ("quadro", analogous to
stereo). It permits connection of RGB cameras.
In quadro mode, the four images are stored in separate memory regions as
separate monochrome images. Cameras must be synchronized for this
operating mode. An on-board sync generator with four separate 75-ohm
outputs makes this easy.
The pixel clock is divided down from a internal Oscillator (up to 180 MHz)
or it is taken directly from the pixel clock input for camera synchronous
digitization. The A/D conversion rates programmable up to 32 MHz.
The region of interest, i.e. the part of the video information that is acquired,
can be defined on a pixel basis for all 4 video inputs with the same values -
not always the full frame has to be acquired.
A Sequencer is included to met the different timings from restart cameras.

1.2.1 Video Input
The eight video inputs are AC-coupled and terminated with 75 Ohm
resistors. Four independent Multiplexes distribute the signal to the four A/D
converters.

Converter 0 Converter 1 Converter 2 Converter 3
Video0 Video1 Video2 Video3
Video4 Video5 Video6 Video7
Video2 Video3 Video0 Video1
Video6 Video7 Video4 Video5
1.2.2 Sync Input
The Sync-input is Composite-Sync and taken from one of the multiplexed
Video-inputs or directly from Video7.
1.2.3 Clock Input
When cameras with clock-output are used, the pixel clock may taken from
the camera. The external clock is AC-coupled and restored to TTL-Level.
To compensate different delays between the Video- and the clock-input, the
phase of the clock can be shifted in steps of 90°.
The clock input is single-ended TTL; it is terminated at the receiving end
(PC_EYE input), with 75 Ohm resistor. How to activate the input see
el_SetVideoFormat.
Caution: Use a separate shielded cable for clock to minimize cross-
talk to video.

Introduction User's Manual
1—6 PC_EYE®2+
1.2.4 Trigger Input
The trigger inputs are opto-decoupled for optimum noise immunity (250 V
isolation voltage). TRIGIN+ is connected to the anode of a LED, TRIGIN-
to the cathode of the LED via an internal 220-Ohm resistor. Since the LED
needs about 10..20 mA for full drive, a 5 V voltage source or a TTL output
is able to drive sufficient current through the circuit. Higher-voltage sources
may be used with additional limiting resistors. This trigger input is level-
sensitive: a high (current is on) will activate continuous snaps; current must
be off to block the acquisition. See also: el_SetVideoFormat
Caution: Do not exceed a maximum of 30 mA LED current!
Alternativly the Optocoupler can be bypassed. In this case the trigger
function is inverted.

1.2.5 Sync / Camera Control Output
For sync and camera control are up to 16 General-Proposes-Outputs
available. The first 12 GPOs are more flexible then the other 4 outputs.
1.2.5.1 Sync / Camera Control Output 0..11
Each Output can be mapped to one of 8 available signals:
· Static output
· Sync-generator Horizontal-sync
· Sync-generator Vertical-sync
· Internal Trigger
· Sequencer bit 2
· Sequencer bit 3
· Sequencer bit 4
· Sequencer bit 5
The logical polarity (High-/ Low-active) is for every Output independently
programmable.
1.2.5.2 Sync / Camera Control Output 12..15
Each one of this 4 outputs can be set to static low or high.
1.2.6 Power Supply out
To supply the cameras with Power, they are up to 4 Outputs with 12 V.
Each Output is protected with a self healing (PTC) 1100 mA fuse.

1.2.7 Data Transfer
Since the PC_EYE-2+ is a Busmaster card, the video data from a Frame or
a whole sequence is moved to memory per DMA-transfer. No need for the
CPU to support this process. The maximum transfer rate in a system is 105
Mbytes/s, but this is a best case. In a real application the transfer rate is
depend of the chipset, graphic card and other active Busmaster cards.

2 Hardware Installation
What you need for installation and use of the PC_EYE family member
boards:
· PC with free PCI slot and Pentium (I -III) CPU.
· The PC_EYE board.
· PC_EYE2+: video camera appropriate for the PC_EYE2+
(monochrome). Mainboard with good PCI throughput because of
high bandwide needs
· Windows 98, ME, NT or 2000 operating system.
· Operation system dependent hardware driver setup and system
independent development files setup, downloaded from the internet
or obtained on CD.
2.1 Installation Procedure:
· Switch off computer,
· Prepare site to observe electrostatic discharge (ESD) precautions
before opening computer or removing PC_EYE from its case: Touch
computer steel case during insertion/removal of PC_EYE or take
other precautions to ensure the absence of high voltages due to
electric charges.
· Open computer case,
· Remove blind back panel,
· Insert PC_EYE board into free PCI slot; the PC_EYE board must fit
into the slot without use of excessive force, make sure it sits firmly
in the slot and the PCI connector’s conductors sit completely inside
the connector.
· Fix PC_EYE back panel with screw,
· Close case,

· Attach video (camera) cables - for a quick start and a first test
camera input #0 should be used with the video camera in free-
running mode. The camera should be known to deliver video signals
(testing can be done by feeding the camera signal to an appropriate
video monitor). See also: Connectors
2.2 Cable

To connect a RGB-Camera, use a standard PC-Monitor cable HD15 to
BNC.
To connect four monochrome cameras with BNC-Output use the ELTEC
cable V-CABL-183A.
PC_EYE 260
To connect four monochrome cameras with Hirose-Output use a standard

2.3 Trouble Shooting - if it does not
work
Check if the driver and the user mode software are installed properly. See
chapter 3.
Grabber is not found by software:
Make sure the grabber is correctly plugged into the PCI-connector. If
mechanical problems can be excluded refer to the driver installation guide
to see if the driver has been installed correctly. Mixing up the recommended
installation order of hard and software can be a possible reason for an
incorrectly installed driver.
Rolling, corrupted image:
If a live image is visible after starting CFG2P, but it is rolling, this may
indicate that the PCI bus speed is not fast enough. Changing the BIOS setup
may help. If not, the motherboard chip set might be to slow. This is
especially true if a stable image can be seen with smaller horizontal region-
of-interest (ROI) settings. Try switching off live mode in CFG2P.If the
image is corrupted and there is no dependency from the horizontal
acquisition width, the graphics board may be responsible for long PCI
blocking times. Disabling video acceleration in the control panel may help;
additionally, switching to a lower pixel depth (8 bpp instead of 16 or 24)
can be helpful.
Getting support:
Under some circumstances (hopefully rare ones...) you may not succeed in
getting everything running. Then you can contact us - but we need the
system configuration as exactly as possible. For that purpose we have
prepared a support request form where you can fill in your configuration
and submit this form (by fax or E-mail) together with the support request -
using this form will help us to help you faster.
