The four RTSI trigger lines on the RTSI bus provide a flexible
interconnection scheme for any DAQPad-6052E sharing the RTSI bus.
The DAQPad-6052E has four trigger lines. These bidirectional lines can
drive any of eight timing signals onto the RTSI bus and can receive any of
these timing signals. This signal connection scheme is shown in
Figure 3-12.
