Trigger on External Event
Figure 9: Various external event schedules
Report schedules can also be triggered by external events, which are manifested to the logger as state changes on the
digital input channels nDS, or as pulses on the counter channels nC:

"
Trigger on the arrival of characters (from an external serial device) at the
DT80
’s Serial Channel (serial
sensor port if
n
= 1, host port if
n
= 2). The trigger can be of the form
1SERIAL""
, where any character arriving triggers the schedule (note that there is no space between
""
),
or
1SERIAL"AbC"
, where arrival of the exact string
AbC
triggers the schedule.
See
.
where:
•
n is a digital channel number
•
m..n is a sequence of digital channel numbers (see
)
•
text is a string of characters arriving at the DT80’s Serial Channel terminals from an external serial device
Note1:
For digital input edge triggering the minimum pulse width is approximately 16ms.
Note2:
If a counter is preset to a value greater than its specified trigger count, the schedule is not triggered. For example, a schedule
set to trigger after 10 counts on digital counter 2 (e.g.
RA2C(10)
) cannot be triggered if counter 2 is assigned a value of 15.
Examples – Digital Channel Event
The schedule header
RC1E
instructs the DT80 to run report schedule C on every transition of digital input 1D.
The following schedule will run whenever digital input
3D
receives a low to high (positive/rising) transition:
RA3+E
