Appendix A: Camera connectors
USB:
Standard Type A (provides power) and Type B (consumes power) USB 2.0 connectors
+ and – terminals provide 5V @ 500mA and ground
respectively for USB2.0 and up to 2A for USB 3.0
- is referenced to EARTH GROUND!!!
D+ and D- handle data communication
USB 3.0 connectors have BLUE insulator while USB 2.0 have WHITE insulator.
USB 2.0 micro, USB3.0 micro, USB 2.0 Type B and USB 3.0 type B connectors
USB 3.0 connectors are backwards compatible with USB 2.0 and USB 1.1 (legacy) connectors
The extra pins on a USB 3.0 connector handle the faster
modes of communication this protocol can switch to.

IEEE1394 (Firewire)
Several “versions” of IEEE1394 compatible connector exist:
IEEE1394a (6 pin), IEEE1394 i.Link (4 pin) and IEEE1394b (9pin) or bilingual.
Pins 1 and 2 on the a and 8 and 6 on the b connector provide power while the rest of them
handle data.
While the newer IEEE1394b has more pins to support higher transfer rates (800MBps as
compared 400MBps for the IEEE1394a, you can use adapters to run an IEEE1394a camera on
IEEE1394b at 400MBps.
Voltage is unregulated and can range from 9V (on a laptop) all the way up to 30V for a typical
power output of 5 to 8W. The firewire card you use should have one of the following connectors
to draw power straight from the PC PSU instead of taxing the PCI backplane. USE IT!!!!
All of them provide 12V (Yellow cable), 5V (red cable) and ground (black cable) connections.
Firewire chipsets compatible with our cards and recommended by other camera manufacturers
include those from Texas Instruments, LSI and NEC. Chipsets from VIA and Pinnacle have
been shown to have poor performance.
Kaspersky antivirus has be shown to interfere with IEEE1394 communications by installing its
own driver. Make sure to uninstall it if you have problems with firewire cameras on a system
with Kaspersky antivirus installed.

Camera Link
This is a fast and efficient camera connection developed specifically for digital camera to frame
grabber connectivity. It utilizes a multichannel LVDS signaling scheme which allows fast, error
resistant communication between the camera and PC interface card.
Different implementations of the Camera Link protocol (base, medium, full, decca) allow
connections with cameras with increasing bandwidth.
While “standard” Camera Link connectors (SDR) use 26 pins there are other types using more
or even less (reduced bandwidth) connectors so many different connectors (even proprietary)
are available for different cameras.

size (left) and mini (right)
Always use PCIe Camera Link frame grabbers with newer systems to ensure optimum
performance. Use the guidelines for connecting PCIe expansion cards to your PC on Appendix
B and identifying expansion card connections on Appendix C.
Although some Camera Link cards
support PoCL (Power over Camera
Link, most cameras do not depend on
it to power the camera as most
cameras have external power
supplies. Still using a high power PCIe
slot or direct connection to the PSU if
available, is advised.

Appendix B: Computer expansion card connections
Install PCIe 1X cards on any available
PCIe expansion slot. If PCIe 16X slots
are available (slot 2 or slot 5) they
should be preferred, followed by slot
4 and 1, 3, 7.
Usually slot 2 will be occupied by the
graphics card so the preferred slot
would be no. 5.

On Z820 computers, the slots available depend on the number of installed CPU’s. Workstations
with only one CPU installed (mid range) will have only slots 1,2,5 and 6 available. Slots 2 and 6
are recommended for installing firewire or frame grabber cards followed by slots 1 and 5.
If two CPU’s are installed (high end) then slots 3 and 4 are also available and slot 3 is preferred
over slot 4.
Do not use PCI slot 7 for anything even if you have a PCI firewire card you think could be used.
Fujitsu Siemens Esprimo P900/910/920
Install PCIe 1X cards on any available PCIe
expansion slot. If PCIe 16X slot are available
it should be preferred. Older Esprimos have
PCI slots for use with legacy PCI firewire
cards. There are no PCI slots available on the
newer Esprimo PC’s.
ALWAYS CONSULT THE DOCUMENTATION OF YOUR COMPUTER TO MAKE SURE THE PCIe SLOTS DO
INFACT OPERATE AT THE SPEED INDICATED BY THEIR PHYSICAL SIZE AND THAT 16x SLOTS ARE NOT
DEDICATED GRAPHICS ADAPTER SLOTS THAT WILL NOT WORK WITH OTHER CARDS.

Appendix C: PCI and PCIe expansion card formats
Peripherals (I/O devices) in PC’s can be either integrated on the motherboard or installed on expansion
slots. Most modern motherboards come with PCIe (PCI express) expansion slots while the older PCI is
still present on older systems. Legacy connectors (ISA, EISA, AGP, NuBus) are no longer used or
supported by modern OS’s. It is strongly recommended to use only PCIe expansion slots for all critical
expansion cards such as USB 2.0 and USB 3.0, IEEE1394 and Camera Link frame grabbers.
PCIe (Peripheral Component Interconnect Express)
PCIe is scalable to accommodate larger bandwidths from 1X to 16X. For this reason a 1x card
CAN be inserted and WILL work on a 4X, 8X or 16X slot, etc. The opposite is most of the times
true too but requires an open back slot and the card will operate at reduced bandwidth.

PCI (Peripheral Component Interconnect)
This legacy expansion slot is slowly phased out but there are still PC’s that use them and many
available cards for them. The most common is the 32bit 5V type, while most cards feature a
universal pinout allowing them to connect to both types of slot.
The much bigger PCI-X or 64bit PCI, was only used on a limited number of workstations and
has been phased out. You can connect 32bit PCI cards on a 64bit PCI slot but only do so if no
other PCI-X cards are connected as this will drop the PCI-X bus speed to that of the slowest
PCI card connected. Connecting PCI-X cards to a 32bit PCI bus is possible only for cards that
can work at half bandwidth. Read your card’s documentation.
ALWAYS CONSULT THE DOCUMENTATION OF YOUR COMPUTER TO MAKE SURE THE PCIe SLOTS DO IN
FACT OPERATE AT THE SPEED INDICATED BY THEIR PHYSICAL SIZE AND THAT 16x SLOTS ARE NOT
DEDICATED GRAPHICS ADAPTER SLOTS THAT WILL NOT WORK WITH OTHER CARDS.
