OPERATION PRINCIPLES
2.1
Functional Overview
RS-644 (LVDS) or RS-422 interface
The
picasso
TM
cPCI-LS uses a AIA-standard 68-pin female connector, so interfacing to cameras
that use this standard also, can be done by using a standard cable. By default the digital interface
is compatible with RS-644 (LVDS). Optional is the RS-422 compatible interface.
The
picasso
TM
cPCI-LS has a flexible front end, so it is compatible with the majority of digital
cameras.
The
picasso
TM
cPCI-LS has two operating modes:
-
MODE0
is for 8,10, 12, 14 or 16 bits single channel cameras or 8 bit dual channel
cameras. In this mode the video timing comes from FEN, LEN, FID (optional), PRSTB
(pixel clock). The exposure output 0 (EXPO0) is active.
-
MODE1
is for two asynchronous 8 bit single channel cameras. In this mode the video
timing from camera A must be connected to FEN, LEN, FID (optional), PRSTB (pixel
clock). The video timing from camera B must be connected to FEN1, LEN1,
FID1(optional), PSTRB1. EXPO0 is for camera A, EXPO1 is for camera B.
FID and FID1 are optional, ask ARVOO Support for more information.
Both modes can acquire images up to 4096 pixels per line by 4096 lines per frame (4 million
pixels maximum).
