Xtium-CLHS PX8 User's Manual
Data Forwarding Setup
Distributed processing of high bandwidth image data is easily configured by inter-connecting
multiple Xtium-CLHS boards. The following description and block diagram shows the simple
physical setup. The user has total control to the actual distributed processing task divisions and
algorithms.
of the first Xtium-CLHS board installed in the first PC. This board is
defined as the “Data Forwarding Master”.
Using a second Camera Link HS cable, connect
of the Data Forwarding Master Xtium-CLHS
board to J3 of second Xtium-CLHS installed in a separate computer or the same as the first
Xtium if it can manage the processing. This second board is defined as the “Data Forwarding
Slave #1”.
Camera Link HS cables used to interconnect Xtium-CLHS boards could be up to 15 meters.
Optionally, the J2 connector of the Data Forwarding Slave #1 Xtium-CLHS board can connect to
J3 of a third Xtium-CLHS (“Data Forwarding Slave #2”).
The number of Data Forwarding Slave boards should not exceed 5, for a total of 6 boards. The
Xtium CLHS boards can either have separate computers or share computers dependent on the
distributed processing requirements.
The Xtium-CLHS driver will automatically detect whether a board is connected to a camera
(becoming the Data Forwarding Master) or is connected to forwarded data (becoming a Data
Forwarding Slave).
Each Data Forwarding Slave board has full control of the camera data portion transferred to the
host computer for processing.
