Installing the MVS-8100
This section describes the steps to install an MVS-8100, describes special case switch
settings, and discusses the connection of external I/O equipment to the 8100.
Steps to Install the MVS-8100
Caution Electrostatic discharge (ESD) can damage the electronic
components of your Cognex hardware. Cognex recommends the
use of a grounded anti-static wrist strap when handling any
electronic components.
1. Before installing your 8100, identify which 8100 you have, using the information in
Table 1. Then configure the on-board jumpers as described in one of the following
sections:
•Jumper Settings for the 8100 on page 48
•Jumper Settings for the 8100M and 8100M+ on page 48
2. Turn off the host PC.
3. Remove the cover of the host PC and select a PCI slot for the 8100. The 8100
requires a PCI slot that supports 5 V signalling. The 8100’s PCI bus connector 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, or both. 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.
PCI Slot Type Key in PCI Slot
Supports 3.3 volt boards Key is towards the back of the PC
Supports 5 volt boards Key is towards the front of the PC
Table 2. PCI slot types

Figure 1. PCI slot types
4. Select the source of +12 V power for the cameras and board by positioning jumper
J3.
Figure 2 shows the J3 jumper position for internal power from the PCI bus. Use this
setting only if you are sure you will connect no more than one camera to the 8100
and will not add cameras later, and you are not using a light control module. The
total available draw for all cameras and light modules with J3 in the 1-2 position is
about 750 mA.

Cognex MVS-8100M Hardware Manual 13
Note If you later change or add cameras or light modules after initial
installation, with the board still configured for internal camera power,
you may exceed the power limitations. For this reason, Cognex
strongly recommends using J3 in the 2-3 position and using cable
300-0175, even when connecting a single camera to your 8100.
Figure 3 shows the J3 jumper position for external 12 V power. The total available
power with the jumper in the 2-3 position is 750 ma for each installed camera and
3.5 A total for all cameras and light modules.
Figure 3. JP1 jumper position and power cable for external camera power
Caution Failure to correctly attach and configure the external power cable to
your MVS-8100 as described in these steps may result in damage to
your frame grabber, motherboard, or both.
5. Press the card into its slot until it is seated firmly, and replace the slot cover screw.
6. Locate the 8100’s external +12 V power connector at J2, as shown in Figure 3 on
page 13. Connect the +12 V power cable adapter (P/N 300-0175) to your PC’s
power supply and to the connector at J2. Both connectors are keyed, and can only
be inserted one way.
Caution Before you attach cameras, be sure the PC’s power is OFF.
Attaching live equipment to the 8100 can result in electrical damage.

7. Connect your camera(s) to the 8100 using the appropriate camera cable, as listed
in Table 20 on page 51. Figure 4 shows the location of the camera ports on the back
panel of the 8100.
Figure 4. MVS-8100 external connector location
Note The 8100’s camera connectors are similar to the connector for a
standard VGA monitor. Attaching a VGA monitor cable to a camera
connector can cause the board to malfunction. However, the
PolySwitch resettable fuse on the camera port should protect the
board from permanent damage. Normal operation is restored after
the incorrect connection is removed.
8. If you are installing one of the following cameras with the MVS-8100M or
MVS-8100M+, see the additional instructions in Using Rapid Reset Cameras on
page 17.
• Sony XC-55 or XC-55 BB camera

10. Replace the PC’s cover and reconnect the power cord.
11. Connect light modules, triggers, strobes, and other parallel I/O equipment to the
8100 before applying power to the PC.
Jumper Settings for 8100M or 8100M+ Only
This section discusses additional jumper settings that may be required if you are using
the 8100M or 8100M+.
Using an External Sync Source
The 8100M and 8100M+ support the use of an external source for HDRIVE and VDRIVE
signals. You can synchronize one to four cameras to the external drive signals.
Note the following points when using an external sync source on the 8100:
• Your cameras must be set in software to use genlock mode in order to synchronize
with the external source.
• Connect the external HDRIVE signal to pin 1, and the external VDRIVE signal to pin
3, of jack J13 on the 8100M. Use pins 2 and 4 as ground returns. See Table 17 on
page 47 for the pinout of jack J13.
• Set jumpers JP6 and JP7 as shown in Table 3.
Note The settings for jumpers JP6 and JP7 affect all four camera ports. If
you set these jumpers to use an external sync source, then you must
use the external sync source on all cameras connected to the
8100M or 8100M+.

Cognex MVS-8100M Hardware Manual 17
Using Rapid Reset Cameras
Cognex uses the term rapid reset to describe electronic shutter control or trigger shutter
control. Cameras that can be used in rapid reset mode include:
• Sony XC-55 or XC-55 BB camera
• Sony XC-ST50 or XC-ES50 camera with switch settings in rapid reset mode
• Pulnix TM-9701 with CCF video format (MVS-8100M+ only)
To use one of these cameras in rapid reset mode with the 8100M or 8100M+, you must
set a jumper for the camera port to which the camera is attached. Table 4 shows the
jumper settings for each camera port. Jumper locations are found in the following
locations:
• For the 8100M, Style A, see in Figure 15 on page 34
• For the 8100M, Style B, see Figure 16 on page 35
• For the 8100M+, see Figure 17 on page 36
Note Setting jumpers JP10 through JP13 for rapid reset support disables
the use of a light module on that camera port. You cannot use rapid
reset cameras and light modules on the same 8100M or 8100M+
camera port at the same time. However, each camera port can be
set individually, so you can mix rapid reset cameras with other types.
Installing External I/O Equipment
You can connect the following peripheral equipment to the MVS-8100M:
• One high-speed optically isolated trigger pulse generator to trigger image
acquisitions on one to four monochrome cameras.
• One high-speed open collector strobe light to allow 8100-controlled illumination of
the scene under one to four monochrome cameras.

• One status output line that can be used by your vision processing application.
• External camera synchronization signals (8100M and 8100M+ only).
• One to four light modules, such as the Cognex acuLight and UltraLight products,
that allow software-controlled dynamic light adjustment of the scene under a
camera lens. See Installing Light Control Hardware on page 23.
Trigger and Strobe Expansion Panel
To connect trigger, strobe, and status lines, use the trigger and strobe expansion panel,
P/N 800-0062. Secure the expansion panel to an unused bus slot position on the PC’s
back panel. A 10-line ribbon cable extends from the expansion panel to the header at
position J1, in the upper right corner of the 8100.
The brown wire in the multi-colored ribbon cable must align with pin 1 on the 8100’s J1
header. Figure 7 shows the expansion panel and the pin numbering of the panel’s
DB-9F connector.

Configuring Cameras
Some of the cameras supported for use with the MVS-8100M require switch settings to
work best with Cognex software, as described in the following sections.
Configuring Sony XC-55 Cameras
The 8100M and 8100M+ support the use of the Sony XC-55 and XC-55BB cameras. If
you purchase your XC-55 cameras from Cognex, they arrive ready to use with the 8100.
If you purchase your XC-55 from a third party, you must configure the camera as shown
in this section.
The XC-55/55BB, as shipped from Sony, is configured to emulate the Sony XC-75
camera. Cognex recommends instead using the XC-55/55BB in its E-DONPISHA II
trigger shutter mode for best performance. Two switch settings convert the XC-55/55BB
to trigger shutter mode; one switch is external, while the other is internal. Follow this
procedure:
1. On the rear panel of the XC-55/55BB, locate the 1N/1I switch. Place this switch in
the 1N position.
2. Remove the cover of the camera control module. Inside the camera control module,
locate the circuit board labeled SG-257.
On the SG-257 circuit board, locate rotary switch S2, which is in the upper right of
a set of four rotary switches as you hold the camera with its top cover up and the
lens mount on the right. Set this switch to the Eposition.
When used with 8100M or 8100M+, the Sony XC-55/55BB must be connected with
Cognex camera cable 300-0239, and the 8100M or 8100M+ must have its rapid reset
jumper set for the camera port used, as described in Using Rapid Reset Cameras on
page 17.
Configuring Sony XC-ES50 Cameras
The MVS-8100M 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.
