There are two types of operations with Permanent I/O elements: simple
monitoring and event generating. Monitoring method is used when current I/O
information needed with regular GPS coordinates. Event generating method is
used when additional AVL packet is needed when current value of I/O exceeds
predefined High and Low levels. I/O settings allow defining I/O event criteria.
Figure 45 I/O settings
Enabled or disabled field
–
allows enabling I/O element so it is added to the data packet
and is sent to the server. By default all I/O element are disabled and FMA120 records only GPS
coordinates.
Priority (AVL packet priority) can be low, high or panic. Regular packets are sent as Low
priority records. When low priority event is triggered, FMA120 makes additional record with
indication that the reason for that was I/O element change. When High priority is selected,
module makes additional record with high priority flag and sends event packet immediately to
the server by GPRS. Panic priority triggers same actions as high priority, but if GPRS fails, it sends
AVL packet using SMS mode if SMS is
enabled in SMS settings
.
High and Low levels
–
define I/O value range. If I/O value enters or exits this range,
FMA120
generates event. “Generate event” parameter defines when to generate event –
when
value enters defined range, exits it or both.
Averaging constant
–
it is an I/O event delay parameter. In some applications there is no
need to generate events on every I/O range enter/exit immediately. Sometimes it is necessary to
wait some time interval before event generating. Averaging constant allows setting I/O event
delay (averaging). If I/O value is entering or leaving predefined range, it must have same value
for Averaging constant time. 1 Averaging constant value equals about 100 milliseconds. In Deep
Sleep mode there is no Averaging.
Note: I/O element’s “Movement sensor” Averaging constant is interpreted as
Start Move Timeout in seconds (from 1 to 59).
Start Move Timeout
–
is a time interval required for movement sensor to be in
the moving state, to consider vehicle as moving.

Monitoring
I/O monitoring starts after enabling I/O element and setting up I/O parameters as it is
shown below:
