The bi-direction I/O functions are introduced as below:
•
Press [On/Off] on the instrument's front panel, the instrument's output is
changed from On to Off. At this point, the pulse signal output from pin 7 can
be detected.
•
When the instrument's [On/Off] is in Off state, input pulse signal to pin 7,
and it will not impact the [On/Off] state.
•
When the instrument's [On/Off] is in On state, input pulse signal to pin 7,
and [On/Off] will be changed from On to Off.
Taking two instruments as an example, the operation is as below:
1. Referring to the figure below, connect pin 7 of two instruments to the exter-
nal oscilloscope.
2. Set pin 7's function of two instruments to Not-Invert and Sync-Off.
3. Confirm that the [On/Off] of both instruments is in On state.
4. Press [On/Off] on the front panel of instrument A to turn off the output
function.
At this time, check the oscilloscope. The instrument A's pin 7 outputs pulse
signal and the instrument B's output function is synchronously turned off.
