Description
Negative component when LVDS signal arriving on LVDS/TTL auxiliary input 6 for an unspecified
acq. path (negative).
See pin 39 for more information.
LVDS/TTL auxiliary input 6 for an unspecified acq. path (positive).
Signals only supported for acq. path 0, 1, and 2: user input 10.
Signals only supported for acq. path 3: data valid input, user input 1, or quadrature input bit 0.
Signals supported for any acq. path: trigger input 2 (main purpose).
RS-232 serial output from acq. path 2 (UART) to video source.
Ground
Negative component when LVDS signal arriving on LVDS/TTL auxiliary input 7 for an unspecified
acq. path (negative).
See pin 43 for more information.
LVDS/TTL auxiliary input 7 for an unspecified acq. path (positive).
Signals only supported for acq. path 0, 1, and 2: user input 11.
Signals only supported for acq. path 3: field polarity input, timer clock input, user input 2, or
quadrature input bit 1.
Signals supported for any acq. path: trigger input 3 (main purpose).
LVDS/TTL auxiliary input 4 for an unspecified acq. path (positive).
Signals only supported for acq. path 0 and 1: user input 8.
Signals only supported for acq. path 2: data valid input, user input 1, or quadrature input bit 0.
Signals only supported for acq. path 3: user input 10.
Signals supported for any acq. path: trigger input 2 (main purpose).
