Description
LVDS/TTL auxiliary input 1 for an unspecified acq. path (positive).
Signals only supported for acq. path 0: field polarity input, timer clock input, user input 2, or
quadrature input bit 1.
Signals only supported for acq. path 1, 2, and 3: user input 7.
Signals supported for any acq. path: trigger input 3 (main purpose).
LVDS/TTL auxiliary input 2 for an unspecified acq. path (positive).
Signals only supported for acq. path 0: user input 6.
Signals only supported for acq. path 1: data valid input and user input 1, or quadrature input bit 0.
Signals only supported for acq. path_2 and 3: user input 8.
Signals supported for any acq. path: trigger input 2 (main purpose).
TTL auxiliary output for acq. path 0.
Supported signals: exposure output 0 (main purpose) or user output 6.
