I only mean that if the tracker sends some special data, then our software parses it to IOX_Y parser items. For example, the device that we've tested before returns:
IO1_1 - digital counter #1
IO1_2 - digital counter #2
IO1_3 - digital counter #3
IO1_4 - digital counter #4
IO2_66 = 13413 external power (13.4 V)
IO2_67=10023 internal power (10.0 V)
IO4_70=346 internal temperature (34 C)
IO2_9 = 13484 - analog input #1 (13.4 V)
IO2_10 - analog input #2
IO2_11 - analog input #3
IO2_19 - analog input #4
But in your case it may be different.
Do you mean that the plugin can read CAN BUS data from device?
If not how can I do ?
