Table 4-1 describes each signal connection on the three BNC connectors.
Table 4-1. I/O Connector Signals
VIDEO± allows for an RSE connection to the video channel. The incoming
video signal must be positive, as shown in Figure 3-2,
CSYNC is a TTL I/O line that is software programmable to be an input or an
output. When the PCI/PXI-1407 is in CSYNC external mode, use the connector
to input a CSYNC signal from the camera. In standard acquisition mode, the
internally generated CSYNC can be routed to this connector as an output
signal.
The TRIG signal is a TTL I/O line used to start an acquisition or to control
external events. You can program the triggers to be rising or falling edge
sensitive. You can also program the triggers to be programmatically asserted or
unasserted similar to the function of a digital I/O line or to contain internal
status signals (by using the onboard events) or specific pulse widths.
