WARNING. Care must be taken when connecting data cables to the camera to insure proper
connection and to prevent damage to the connector.
Data Signals
Table 7: Data Signal Definition
Signal Description
D*0+, D*0- Data bit 0 true and complement—Output. (Least significant
bit.)
D*1+, D*1- Data bit 1 true and complement—Output.
D*2+, D*2- Data bit 2 true and complement—Output.
D*3-D*10+,- etc. Etc.
D*11+, D*11- Data bit 11 true and complement—Output. (Most significant
bit.)
Digitized video data is output from the camera as LVDS differential signals using 4
Molex 60-pin connectors on the rear panel (labeled “DATA 1 through DATA 4”). The
data is synchronous and is accompanied by a pixel clock and clocking signals.
Data Clocking Signals
Table 8: Clock Signal Descriptions
Signal Description
PIXCLK+,
PIXCLK-
Pixel clock true and complement. 40MHz—Output.
Data is valid on the falling edge.
HSYNC+,
HSYNC-
Horizontal sync, true and complement—Output.
HSYNC high indicates the camera is outputting a valid line of data.
VSYNC+,
VSYNC-
Vertical sync, true and complement—Output.
VSYNC high indicates the camera is outputting a valid frame of data.
2.6 Serial Communication
Connector and Pinout
The serial interface provides control of frame rate, integration time (shuttering), video
gain and offset, external trigger and external integration. For information on how to
control these functions, see Camera Operation, beginning on page 20. The remote
interface consists of a two-wire (plus ground) full duplex RS-232 compatible serial link,
used for camera configuration, and two back panel SMA coax connectors used for
external trigger input and output.
IMPORTANT:
This camera uses the
edge of the pixel
clock to register data.
