View into female jack

Note: Data frequency is dependent on binning mode. Reference section 3.9 – Triggering,
Integration, and Frame Rate Overview.
Data Clocking Signals
Table 8: Clock Signal Descriptions
Signal Description
PIXCLK+,
PIXCLK-
Pixel clock true and complement. 20MHz (unbinned) -- Output.
Data is valid on the falling edge. Note that data and PIXCLK frequency
is
dependent on binning mode. Reference section 3..9 – Triggering,
Integration, and Frame Rate Overview
HSYNC+,
HSYNC-
Horizontal sync, true and complement--Output.
HSYNC high indicates the camera is outputting a valid line of data. The
number of valid lines in a frame depends on binning mode. Reference
section 3.9 – Triggering, Integration, and Frame Rate Overview.
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, pixel binning, external trigger and external integration (for information
on how to control these functions, see “Operating the Camera” later in this document).
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
The camera uses an RJ-11 telephone-style connector for serial
communications, with four conductors installed in a six-
position connector. Note that both four- and six-
conductor plugs may be used interchangeably with the
RJ-11 jack.
IMPORTANT: Both the PC/AT and the camera are
configured as “DTE” (Data Terminal Equipment)
devices requiring the TXD and RXD lines to be swapped
when interconnecting the two (note that pin 4, normally
the yellow wire, is not used on the RJ-11.) That is, the
TXD pin represents DATA OUT and the RXD pin
represents DATA IN on both devices, so that one device’s TXD line must connect to the
other device’s RXD line and vice-versa.
