The MVS-8600 DualLVDS configuration, which corresponds to Configuration 3 described in the section Loadable Software I/O Configurations of the MVS-8600 Hardware Manual, lets you use two line scan cameras, both using LVDS encoders.
Note: This configuration is not available on the MVS-8601.
VisionPro reads the MVS-8600 I/O configuration from the VisionPro.ini file in the Windows or WINNT directory. To use the DualLVDS configuration for your MVS-8600 series frame grabbers, make sure these lines appear in VisionPro.ini:
[CogFrameGrabber8600 #0] IOConfig = DualLVDS
The following picture shows an MVS-8600 frame grabber.

The Hirose HR10 connector at P3 connects to an I/O Connection Module (part number 800-5885-1) which provides you with screw terminals to connect to tiggers, strobes, and encoder devices.

Each configuration uses a different cable to connect the Hirose HR10 connector to the I/O Connection Module. For the DualLVDS configuration, you must use cable part number 300-0538.
The P4 and P6 connectors on the MVS-8600 connect to your computer's back plane with one or two I/O extension cables (part number 300-0240) which provides you with DB-25 connectors that give you access to other I/O lines as well as some of the same signals that the HR10 connector provides.

In the DualLVDS configuration, the MVS-8602 provides 6 programmable input lines. Three lines come from the P4 connector, and the other Three come from the P6 connector.
In the following table, the positive pin is given first, then the negative. For example, "3 (+) and 4 (-)" means that pin3 is positive, and pin 4 is negative.
| Software Input Line | Signal Name | P4’s 300-0240 Pins on DB-25 | P6’s 300-0240 Pins on DB-25 |
| 0 | Not available in DualLVDS configuration | – | – |
| 1 | Not available in DualLVDS configuration | – | – |
| 2 | OPTO_IN_2± | 11 (+) and 12 (-) | – |
| 3 | OPTO_IN_3± | 11 (+) and 13 (-) | – |
| 4 | OPTO_IN_4± | – | 3 (+) and 4 (-) |
| 5 | OPTO_IN_5± | – | 3 (+) and 5 (-) |
| 6 | OPTO_IN_6± | – | 11 (+) and 12 (-) |
| 7 | OPTO_IN_7± | – | 11 (+) and 13 (-) |
In the DualLVDS configuration, the MVS-8600 provides 8 programmable output lines. Four lines come from the P4 connector, and the other four come from the P6 connector.
In the following table, the positive pin is given first, then the negative. For example, "3 (+) and 4 (-)" means that pin3 is positive, and pin 4 is negative.
| Software Output Line | Signal Name | P4’s 300-0240 Pin on DB-25 | P6’s 300-0240 Pin on DB-25 |
| 0 | Not available in DualLVDS configuration | – | – |
| 1 | Not available in DualLVDS configuration | – | – |
| 2 | OPTO_OUT_2± | 9 (+) and 10 (-) | – |
| 3 | OPTO_OUT_3± | 22 (+) and/ 23 (-) | – |
| 4 | OPTO_OUT_4± | – | 15 (+) and / 16 (-) |
| 5 | OPTO_OUT_5± | – | 1 (+) and 2 (-) |
| 6 | OPTO_OUT_6± | – | 9 (+) and 10 (-) |
| 7 | OPTO_OUT_7± | – | 22 (+) and 23 (-) |
Triggers, strobes, and encoder outputs are available through the I/O Connection Module. Some of the signals from the I/O Connection Module are also duplicated in the P4 and P6 connectors.

In the DualLVDS configuration, the trigger and strobe connections are opto-isolated.
