Timing Chart
Example: Three Data Items Set for Parallel Data Output
1
Turn ON the TRIG signal while the BUSY signal is OFF.
2
Measurement begins and the BUSY signal is turned ON during the measurement process.
3
When the measurement has been finished, the measurement result is output using an OR signal,
and the BUSY signal is turned OFF.
*1
*1 You can also set the [BUSY output] parameter so that the BUSY signal is turned OFF after the completion of data logging, image logging,
or displaying results.
4
Turn ON the DSA signal from the external device to request data transmission after you have
confirmed that the BUSY signal is OFF.
*2
*2 If you do not turn ON the DSA signal within the specified timeout time after measurements are completed, a timeout error will occur. (This
is timeout time 1.)
5
When the DSA signal turns ON, the D0 to D31 signals are output and the GATE signal is turned
ON.
6
When the DSA signal is turned OFF, the GATE signal turns OFF.
*3
*3 If you do not turn OFF the DSA signal within the specified timeout time after the GATE signal turns ON, a timeout error will occur. (This is
timeout time 2.)
7
If more than one data item is being output for one measurement and you do not turn ON the DSA
signal within the specified timeout time after the GATE signal turns OFF, a timeout error will oc-
cur. (This is timeout time 3.)
If the DSA signal does not t u rn O N
w ithin the specified time after
meas u rements are completed, a
timeo u t error w ill occ u r.
If more than one data item is b eing o u tp u t for one
meas u rement and the DSA signal does not t u rn
O N w ithin the specified time after the GATE
signal t u rns OFF, a timeo u t error w ill occ u r.
If the DSA signal does not t u rn OFF w ithin the specified time
after the GATE signal t u rns O N , a timeo u t error w ill occ u r.
