Table 3 Available I/O elements
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 GNSS coordinates. Event generating method is used
when additional AVL packet is needed when the current value of I/O exceeds
predefined High and Low levels. I/O settings allow defining I/O event criteria.

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 only main I/O elements are.
Priority (AVL packet priority) can be low, high or panic. Regular packets are sent
as Low priority records. When low priority event is triggered, DB3 Plug&Play
makes an additional record with an indication that the reason for that was I/O
element change. When High priority is selected, the module makes an
