On this page you will find Digital Optics drivers for a variety of digital cameras and video frame grabbers as well as documentation and sample code for programmers wishing to write drivers. These drivers are suitable for V++ and VSpec Pro only.

Nikon Digital SLR Cameras

Digital Optics has partnered with Tetherscript Technology Corporation, the manufacturer of ControlMyNikon, to integrate comprehensive Nikon SLR camera control functions into V++. This driver is a specially designed plug-in that makes the entire functionality of Tetherscript's ControlMyNikon application available from within V++.

Supported cameras include: D3, D3S, D3X, D300, D300S, D40, D40x, D60, D80, D90, D200, D700, D800, D5000, D5100, and D7000. Other Nikon camera models may also be compatible with the listed models - please contact us if your camera is not listed.

IMPORTANT: To use this plug-in, you MUST purchase a registration code for the ControlMyNikon product. This can be supplied by your V++ distributor, or directly by Digital Optics, or may be obtained from the ControlMyNikon web site.

In order to setup the plug-in correctly you should install it using the installer provided here, which will also install the original ControlMyNikon product (currently version 4.3).

IMPORTANT: Release of V++ ControlMyNikon 5.0 is pending.

Allied Vision Technologies Gigabit Ethernet (GigE) Cameras

Allied Vision Technologies (AVT) produces a wide range of GigE cameras, all of which are supported in V++ by this driver. Any AVT or Prosilica camera that confirms to the PvAPI interface standard can be controlled using this driver.

The driver is a comprehensive implementation of PvAPI and supports synchronous and asynchronous image capture, live focussing, regions of interest, and advanced settings. Control from VPascal modules is fully supported, including directly modifying camera attributes. Multiple GigE cameras may be controlled simultaneously, if supported by your network architecture.

Hamamatsu Photonics DCAM Digital Cameras

This driver supports all Hamamatsu DCAM-compatible digital cameras. It is designed to operate with DCAM version 2.1.3 or later, and supports all modes of operation including continuous streaming for rapid focus. Multiple camera control is fully supported. Version 2.0 of the driver adds support for the "universal" extended commands including hardware sub-arrays, hardware brightness and contrast, temperature control and monitoring, and other advanced camera settings.

Imaging Technology Itex-IC

This driver was developed for the Imaging Technology IC-DIG digital frame grabber and requires that Itex version 2.7.1 is installed. The driver should also work with other boards in the Itex-IC range but this has not been tested. It is capable of real time focus and frame capture. You must configure the driver before attempting to access the Itex board (do this using the Video | Configure command in V++). In particular, you should use the Itex Configurator to create a configuration file for your camera.

Imaging Technology Overlay Frame Grabber

This is a native driver for the Imaging Technology OFG board and requires no other software at all. However, this version can only be used under Windows 95/98. You must configure the driver before attempting to access the OFG board (do this using the Video | Configure command).

Imagraph Imascan frame grabbers

This driver was developed by a third party for the Precision / ChromaP boards and cannot be downloaded directly from the web site. Please contact Digital Optics if you require the Imascan driver.

This is not a Windows display driver for Imagraph products. It is a video capture driver specifically for the V++ software and does not include any Windows installation files.

MRT VideoPort Professional PC-Card frame grabber

The MRT VideoPort Pro is a PCMCIA color frame grabber suitable for use with notebook computers. You must install the standard Windows drivers for the VideoPort before the V++ driver can operate.

How to install a Digital Optics video driver

The ZIP files you can download above contain Windows installers for Digital Optics video drivers. Unzip the file and copy the self-installing EXE files to your hard drive. The drivers are compatible with V++ and VSpec Pro only.

To install a driver you must close V++ / VSpec Pro and run the installer. The driver will be automatically loaded next time you start the software. Always check the configuration settings (using the Video | Configure menu command) before capturing images.

IMPORTANT: Ensure that you have installed the frame grabber itself according to the manufacturer's instructions and any Windows drivers it may require before attempting to install or load the V++ driver.

Always read the Readme.txt file when is is displayed during the installation.
