Sharp IV-S30J User Manual page 222

(6) Measurement start input = CCD trigger, start sampling = parallel, object type change =
parallel, result output = computer link/parallel
When the start sampling input (X0) is turned ON, the CCD trigger is enabled. (Sampling starts)

Note 1: When the settings listed in section "16-3 CCD trigger" have not been made, a "CCD TRIG
NOT SET. (error 34)" will occur.
Note 2: Start sampling input (X0)
1. Sampling will be performed while this input terminal is ON. When it is turned OFF, the
sampling will stop. During sampling, O will flash in the upper right corner of the operation
screen.
2. After the measurement is terminated, the sampling will be restarted when the X0 terminal
is changed from OFF to ON.

When a Sharp PC is used, a write enable command (EWR) is transmitted from the IV-S30J to the
PC in the following cases.
- When the power is applied to the IV-S30J.
- When a write mode nonconformity error (code 10
is transmitted (when the power is disconnected from the PC).
- When the output method is changed from the "OUT I/F (PARAL.)" to the "COMPUTER LINK."
