PXR Cables & Accessories


The Imagenation PXR800 frame grabber and PXR801 camera extender board have high-density DB-26 connectors for camera interface (two each).

There are no commercially available cabling solutions for the PXR800 through third party vendors. You have the option to purchase Imagenation PXR800 cables - two designs of pre-wired cables are available — the Full Use Cable (CB-081) and the Video/Trigger Only Cable (CB-082) — or build the cables yourself (refer to Chapter 5 of the User's Guide).

Full Use Cable (CB-081) provides the user access to each of the signals on the PXR800 26-pin connector, allowing for easy interconnection of system hardware and detailed application development. All signals are made available on BNC connectors except 12V power, which is provided on a 2.5mm inside diameter female power plug and the optically isolated trigger signals, which are on a 3 pin female DIN connector. For complete connector pin assignments and cable design advice, refer to Chapter 5 of the User's Guide, Cables and Connectors.

Video/Trigger Only Cable (CB-082) provides only the video input and TTL trigger input, each on a BNC connector, permitting quick implementation of simple image capture applications.

Camera Extender Board

A separate Camera Extender Board (PXR801) enables easy, cost-effective cabling and set-up for 3- and 4-camera applications. This device plugs into the PXR800 and provides two additional 26-pin connectors for attaching the third and fourth cameras.
