Cognex MVS-8100L Hardware Manual 9
MVS-8100L Hardware
Installation
This chapter describes how to install the Cognex MVS-8100L frame grabber in a host
PC.
Host PC Requirements
The host PC must meet the following minimum requirements to support MVS-8100L
frame grabbers:
• The motherboard’s chip set must be fully compliant with the PCI 2.1 specifications
or later. Motherboards with Intel chip sets that support Intel Pentium MMX, Celeron,
Pentium II, Pentium III, Pentium 4, and Xeon CPUs are known to be compliant.
Motherboards with VIA chip sets that support the AMD K6-2 and Athlon CPUs are
known to be compliant.
• One available two-thirds length PCI slot for the MVS-8100L.
• A CD-ROM drive, or access to one over a network, to install the Cognex software.
Additional requirements may be imposed by your Cognex software package. Check the
Cognex software’s release notes for the software’s requirements, if any, on:
• Minimum recommended CPU speed
• Host operating system, including the supported service pack release level
• Supported video cards
• Desktop color depth (the number of colors displayable)
• Desktop size (the number of pixels displayable in width and height on your screen)
• The presence of a mouse or other pointing device
Note Cognex strongly recommends using an AGP video card with the
MVS-8100L. Using a PCI video card will result in reduced frame
rates and higher CPU usage when displaying live video.
Installing the MVS-8100L
The MVS-8100L frame grabber board installs in a PCI slot of the host computer.
Expansion panels for additional cameras and trigger and strobe control can be installed
in unused slot positions.
Before you begin, determine your camera configuration, camera power requirements,
and the trigger and strobe control method. See your software release notes for the list
of cameras that are supported for your hardware.

10 Cognex MVS-8100L Hardware Manual
Caution Electrostatic discharge (ESD) can damage the electronic
components of your Cognex hardware. We recommend the use of a
grounded anti-static wrist strap when handling any electronic
components.
To install the MVS-8100L frame grabber:
1. Power off the host PC.
2. Remove the cover of the host PC and select a PCI slot for the MVS-8100L. The
MVS-8100L requires a PCI slot that supports 5 V signalling and is slotted to allow
placement only in a 5 V slot (which are the most commonly found PCI slot types).
Motherboard PCI slots are keyed to allow acceptance of boards that use either 5 V
or 3.3 V signalling. The bus connectors on all PCI boards are slotted to disallow
placement of the board in the wrong type of slot. PCI slot keys are described in the
following table and diagram.

3. Select the source of +12 V camera power by positioning jumper JP1. Figure 2
shows the JP1 jumper position for internal camera power. The total available power
with the jumper in this position is approximately 750 ma for all installed cameras.
Figure 2. JP1 jumper position for internal camera power
Figure 3 shows the JP1 jumper position for external camera power. The total
available power with the jumper in this position is 750 ma for each installed camera
and no more that 3.5 A total for all cameras.

Note Changing or adding cameras after installation with the board
configured for internal camera power may result in exceeding power
limitations.
4. Insert the MVS-8100L into its PCI slot until it is seated firmly and replace the slot
cover screw.
5. If you selected internal camera power in Step 3, proceed to step 6.
If you selected external camera power in Step 3, connect the appropriate external
power cable between connector JP2 on the MVS-8100L and the +12V power
supply of the host PC as shown in Figure 3 on page 11. Both connectors are keyed
and can only be inserted the correct way.
See Selecting an External Power Cable on page 14 to determine the part number
of the external power cable to use.
6. If you are not installing the camera port expansion panel, proceed to the next step.
If you are installing the camera port expansion panel, Cognex P/N 300-0177,
secure it in an unused bus slot position. Connect the 30-pin connector to the
camera expansion header (JP3) on the MVS-8100L so that the red edge of the
ribbon cable connector aligns with pin 1 as shown in Figure 4 and Figure 5.

or both.
7. If you are not using the trigger and strobe expansion panel, proceed to the next
step. If you are using the trigger and strobe expansion panel, Cognex P/N
800-0062, install it in an unused slot position. Connect the ribbon cable to
connector JP4 on the MVS-8100L so that pin1 on both connectors are aligned as
shown in Figure 6 and Figure 7.

8. Replace the cover of the host PC.
9. Connect external I/O equipment as required. See Configuring Cameras on
page 16.
10. Connect cameras as required. See your software release notes for information
about available cameras and required camera cables.
Note Connect cameras and external I/O equipment before applying
power to the host PC.
11. Restore power to the PC and test as required.
Selecting an External Power Cable
Step 3 of the installation instructions describe the use of an external power cable under
certain circumstances. The external power cable is plugged into jack JP2 to supply
+12 V power for attached cameras.
MVS-8100L boards with board label 801-8136-04 or later have a locking jack at position
JP2. This jack is designed to be used with power cable 300-0391. This cable has a
matching plug that locks firmly into place in the new jack.
MVS-8100L boards with board labels earlier than 801-8136-04 use the original external
power cable, 300-0175.

Configuring Cameras
Some of the cameras supported for use with the MVS-8100L require switch settings to
work best with Cognex software, as described in the following sections.
Configuring Sony XC-ES50 Cameras
The MVS-8100L supports the use of the Sony XC-ES50 family of cameras, including the
XC-ES50 and XC-ES50CE. If you purchase your XC-ES50 cameras from Cognex, they
arrive ready to use. If you purchase your XC-ES50 from a third party, you must configure
the camera as shown in this section.
Figure 8 shows the back panel of the Sony XC-ES50 camera with the switches in their
factory default position.
Figure 8. Sony XC-ES50 camera back panel
To configure the switches for the Sony XC-ES50 camera:
1. Configure the 10-position DIP switch as shown in Figure 8.
Note You can set switch 5 to ON in factory default mode to use field
integration rather than frame integration (single field and
half-resolution video formats only).
2. Set the manual gain switch in the fully vertical position.
3. Set the HD/VD switch to external (EXT).
4. Set the 75Ω switch to ON.

rather than frame integration (single field and half-resolution video
formats only).
2. Set gain to the “F” position.
3. Set the INT EXT switch to external (EXT).

Connecting External I/O Equipment
You can connect the following external I/O equipment to the MVS-8100L:
• One high-speed optically isolated trigger input that triggers image acquisitions on
one to four monochrome cameras
• One high-speed strobe output that allows MVS-8100L-controlled illumination of the
scene under one to four monochrome cameras
• One software-controlled optically isolated output that can be used by your vision
processing application as an accept/reject or status control line
Trigger and strobe lines can be connected to either the trigger and strobe expansion
panel or to certain pins on the camera port 1 connector. Status output lines can only be
connected to the trigger and strobe expansion panel.
Note Either camera port 1or the trigger and strobe expansion panel can
be used to provide trigger and strobe signals. Both sources can not
be used to provide signals at the same time
Connecting I/O Lines to the Trigger and Strobe
Expansion Panel
To connect I/O lines to the trigger and strobe expansion panel:
1. Ensure that the trigger and strobe expansion panel is installed correctly. See
Installing the MVS-8100L on page 9.
2. Make up external lines and connect them to the DB- 9F connector. See Trigger and
Strobe Expansion Panel on page 31 for schematic, signal, and pinout information
for the DB-9F connector.
Connecting I/O Lines to Camera Port 1
With the use of a special Cognex camera cable, camera port 1 can supply both camera
and trigger and strobe signals. The accept/reject I/O status line is not available through
camera port 1.
To install I/O lines to camera port 1:
1. Connect the camera splitter cable, Cognex P/N 300-0178, to camera port 1. This
cable separates the trigger and strobe lines from the camera control lines.
2. Make up external I/O lines and connect them to the RJ-12 jack of the camera splitter
cable. See Camera Splitter Cable on page 27 for pinout of the RJ-12 jack.
