What is PoCL?
Power over camera link (PoCL) is a recently approved standard by the AIA. PoCL provides power to the camera over the camera link cable. It was derived from the current camera link standard and first proposed by CIS Corporation, which led a Working Group to develop and author the outline of this standard together with Active Silicon Ltd.
The PoCL standard allows the camera link cable
to supply power to the camera. This solution is
particularly suitable for a small digital camera
since this allows cameras to be installed in a
smaller physical area.
CIS PoCL product lines
Most of CIS camera link cameras will offer new PoCL compatible cameras starting this summer.
PoCL Standard details
There are currently two Camera Link standard annexes for PoCL. Annex D and Annex E.
Annex D is a electrical descritions, allowing manufacturers to create cables optimized for varying combinations of length, diameter, and flexibility. Annex D defines a connector that permits Camera Link to be integrated into miniature and remote-head cameras.
Annex E provides an optional feature for powering and controlling the camera using a single cable similar to USB and FireWire. This capability eliminates the need for a separate power cable while providing full backward compatibility for systems that do not use PoCL.
Gig-E and PoCL working together
With a CIS's new multiplexer, the CL-GE300, you can have up to three camera link cameras linked to a Gig-E connection, providing multiple image processing without compromising superior vision camera quality.
