Using Multiple Boards
You can also combine multiple boards, i.e.,
- use multiple OPTO Trigger 5 boards with one frame grabber board, or
- use one OPTO Trigger 5 board with multiple frame grabber boards.
You connect the frame grabber(s) to the OPTO Trigger 5 board(s) by a specific 34-pin flat cable (see below). The signals of this cable use open collector drivers.
Using one OPTO Trigger 5 for several frame grabbers makes synchronizing the frame grabbers most easy. By sharing the trigger input lines of OPTO trigger 5, all frame grabbers in the PC are accurately synchronized. All frame grabbers connected to one OPTO trigger 5 must be seated in the same PC.
In most use cases, one OPTO Trigger 5 synchronizes all frame grabbers seated in one host PC. This is useful if the acquisition is controlled by an external generator.
Only Connect Devices residing in ONE Host PC |
|
|
Do NOT connect frame grabbers residing in different host PCs. |
|
Special 34-pin Flat Cable |
|
|
To connect the devices in the host PC (one or several Opto trigger 5 boards and one or several frame grabbers), use a custom-tailored 34-pin flat cable which provides all required connectors in the desired order. Please contact Silicon Software sales department for ordering information. |
Pins that must not be connected |
|
|
Don't connect the following pins between two frame grabbers:
If you use the special 34-pin flat cable available from Silicon Software, these lines are already disonnected directly on the cable. |
Synchronization without External Trigger Inputs |
|
|
There are applications where no external source is available or desired. In these cases, synchronization of multiple frame grabbers is not possible via OPTO trigger 5. Instead, a master frame grabber needs to synchronize all its slave frame grabbers. |
Special Cases with some microEnable IV Products |
|
|
microEnable IV AD4-CL, microEnable IV AD4-LVDS, and the microEnable IV VD4-CL with implemented I/O option "3.3V TTL (LVTTL) compatible (push/pull)" DO NOT allow the connection of two or more microEnable IV frame grabbers via the flat cable. |
