Button IO Feature
|
Purpose of this functionality is to generate event on button click to let user know which button was clicked and what action was done (if action is configured). Events will be generated only if one (or both) buttons are selected in the Event Button Source parameter and only for selected buttons.
Button IO Feature events are generated with AVL ID 389.
Feature Settings parameter sets the priority of event:
Low Priority - Generates record and sends it to server with next data transmission.High Priority - Generates record with High priority flag and sends event packet immediately to the server using GPRS.
