If building your own cable, you can purchase the following part:
Manufacturer:
Connector and shell:
Ensure that the cable is a twisted-pair type cable, twisted along signal pairs.
External auxiliary I/O connector 0
External auxiliary I/O connector 0 is a high-density DB-44 female connector,
located on the bracket of the cable adapter board. This connector is used to
transmit/receive communication and auxiliary signals; the auxiliary signals can be
used to route data valid, field, timer clock, trigger, exposure, or user-defined
signals. This connector interfaces with the 50-pin internal auxiliary I/O connector
on the board, making the I/O signals accessible outside of the computer enclosure.
The pinout for this connector is as follows. The description of each (positive)
auxiliary signal states whether the signal is specific to an acquisition path and the
type of signals that can be routed onto it.
Description
RS-232 serial input to acq. path 0 of frame grabber (UART).
Opto-isolated auxiliary input for acq. path 0 (positive).
Supported signals: trigger input 0 (main purpose) or user input 4.
Ground
Negative component when LVDS signal arriving on LVDS/TTL auxiliary input 0 for an unspecified
acq. path (negative).
See pin 20 for more information.
Negative component when LVDS signal arriving on LVDS/TTL auxiliary input 1 for an unspecified
acq. path (negative).
See pin 6 for more information.
