Page 11: Units, Connectors, And Channels
If you are using multiple EDT boards (units), or multiple connectors on a single EDT board, the software assigns a unique handle to represent each unit and connector. Unless you specify a different unit number, connector number, or both, all EDT example and utility applications will default to unit 0, connector 0. -
Page 12: Leds
Most cameras have a manufacturer-defined serial command set for camera control and status. To utilize this capability, EDT boards implement serial transmit and receive using standard serial lines as defined by the Camera Link standard. You can use serial communication in a number of ways, as discussed below. -
Page 13: From Your Application
From Your Application To see all of the routines needed for user applications to send and receive serial commands: In the EDT API (see 7), follow the link to the EDT digital imaging library, and then — under Modules at the Related Resources on page bottom of the page —... - Page 14 (width, height, depth, etc.) to specific values; and optionally sends serial initialization commands to the camera from the referenced configuration file. Configuration files are in your EDT installation package under camera_config. The EDT camera selector GUI applications (vlviewer, pdvshow) are simply wrappers to provide a way to select the correct file, then shell out to call initcam.
- Page 15 Shows how to use the API to acquire images from a camera linked to the board and (optionally) save the images to files. To add image acquisition to an application, EDT recommends starting with this example, which shows how to use the ring buffer routines to improve performance by pipelining image acquisition and processing.

Page 16: Triggering
11). Triggering EDT provides configuration files for most cameras running in freerun mode (i.e., no triggering), and also some files for cameras running in triggered or pulse-width modes. This section describes common triggering modes supported by EDT, with abbreviated information on configuration file directives and subroutines. For more complete information,... -
Page 17: Triggered By Edt Board (On-Demand)
API subroutine Camera-specific range and units. Triggered by EDT Board (Fixed Period) In this mode, the board sends a fixed periodic trigger signal over a camera control line, typically CC1, for each frame or line of image data. For area scan cameras, use the following information... -
Page 18: Pulse-Width Triggered (Controlled Or Level)
External Trigger Passthrough In this mode, a trigger is sent from an external source directly to the board, which passes it to the camera on a camera control line, typically CC1. EDT, Inc. 2019 April 29... -

7), register 0x10, bit 7. Fire the trigger by applying a TTL signal lasting at least 200 nanoseconds to these pins, which in turn will output a signal of the appropriate level to a camera control line, typically CC1. EDT, Inc. 2019 April 29... -

For Linux, pciload is an application in the installation directory (see Installation on page To see currently installed and recognized EDT boards and firmware, enter... pciload The program outputs the date and revision number of the firmware in the flash memory. -
Page 24: Corrupted Firmware
Most often, firmware corruption is the result of an interrupted load process or an unanticipated interaction with the host computer; if so, following the procedure below should solve the problem. If the firmware file itself has become corrupted, first contact EDT for the current firmware you’ll need to replace it, and then follow this procedure. -
Page 25: Board Not Seen
– for instance, a four-lane board will not work properly in a slot wired for only one lane (see Requirements on page — EDT drivers typically will not work with “guest only” accounts, so if you are using such an account, change to an account with greater access. See also... -
Page 26: Corrupted Images, Slow Acquisition, Timeouts, Data Loss
• Verify that the EDT board is in a PCIe slot that is wired electrically (not just physically) to support the number of lanes provided by the board. For example, a four-lane board requires a slot that has four or more lanes. Also, note that some motherboards will “split”... -
Page 27: Problems With Bandwidth
• Try a different camera, if available. • Verify that the EDT installation package was installed correctly and that the driver is running and can see the board. To do so, in the installation directory (see Installation on page 8), go to the command line and enter... -
Page 28: Problems With Your Applications
VisionLink F-series Troubleshooting For best performance, install your EDT board in a bus that is not shared with any other devices and that meets the board’s speed requirements, as discussed in Requirements on page Problems With Your Applications In applications using EDT libraries, a mismatch between driver and library software versions can cause application or system failures. -

The time thus captured combines the time derived from an IRIG-B input with a high-resolution counter for computing fractional seconds. EDT’s current IRIG-B format (IRIG2) is the second such format used for VisionLink frame grabbers. NOTE EDT’s former IRIG-B format (IRIG1) is now obsolete. - Page 34 Table 9. Elements of IRIG2 Footer Element Offset Size Type Notes This should be ASCII “EDT” followed by 01 (or 0x45445401). Magic u_int Frame u_int This is the frame counter, which is reset when reset_intfc bit is cleared – normally at the start of acquisition.
- Page 35 IRIG API In the EDT digital imaging library routines, extra data added by the board or software (outside of the defined image) typically is called a header. In this case, however, such data is at the end, so it is called a footer.
