Input Signal
START IN (Negative logic)
Use this signal to perform GO/NO-GO determination by synchronizing to an external input signal.
The signal is only valid when on the GO/NO-GO menu, Remote is set to ON. If Remote is set to
OFF, GO/NO-GO determination is performed regardless of the external signal input (the GO/ NO-
GO determination result is output).

Output Signal
NOGO OUT (Negative logic)
When the determination result is NO-GO (fail), the output signal level temporarily changes from high
(H) to low (L).
GO OUT (Negative logic)
When the determination result is GO, the output signal level temporarily changes from high (H) to
low (L).

The signal remains low until the DL850/DL850V
is ready to accept the next measurement.
The duration is longer during output to a built-in
printer or internal storage medium.
START IN is not referenced when Remote
is set to OFF; GO OUT and NO-GO OUT
are output according to internal
GO/NO-GO determination.
