FTC881 Configuration > FTC881 Input/output (I/O)When no I/O element is enabled, AVL packet comes with GNSS information only. After enabling I/O element(s) AVL packet contains current value(s) of enabled I/O element(s) along with GNSS information.
Search
Enter the keyword to search for the desired permanent I/O.
More Filters
It provides additional filter options such as Priority, Operand, and rows with currently available values.
View Columns
Filters the necessary tabs when making configuration changes or viewing. Priority, Operand, Low Level, High Level, and Event Only Options are available filters. The Input name and Current Values are permanent columns.
Permanent I/O
I/O element name.
Current Value
If the device is connected to the Configurator, then all the current I/O values can be seen here.
Units
Units of measurement.
Priority
This field allows the enabling of the I/O elements and sets them a priority so they are added to the data packet, which is sent to the server. By default 7 I/O elements with Low priority are enabled: Ignition, Movement, GSM Signal, External Voltage, Battery Voltage, Battery Current, Total Odometer. All records made by FTC881 are regular, and regular packets are sent as low priority records.
Priority level (AVL packet priority) can be:
None Priority
The module doesn't make additional records.
Low Priority
The module makes an additional record with an indication that the event was caused by an I/O element change (depending on Operands configuration).
High Priority
The module makes an additional record with High priority flag and sends event packet immediately to the server using GPRS.
High and Low Level
These levels define I/O value range. If I/O value enters or exits this range, FTC881 generates an event.
Event Only
When this is selected, I/O element status value will be appended only to eventual records, otherwise I/O element status value will appear in each AVL record.
Operands
Defines when to generate event: On Exit, On Entrance, On Both, Monitoring, On Hysteresis, On Change or On Delta Change.
Operand On Exit
Record is generated when input value leaves a range between low and high level limits.
Operand On Entrance
Record is generated when input value enters a range between low and high level limits.
Operand On Both
Record is generated by both On Exit and On Entrance operands' logic at same time.
Operand Monitoring
No event at all. Values are recorded only when other triggers worked.
Operand On Hysteresis
Record is generated when input value crosses the high limit value from below the low limit value or vice versa.
Operand On Change
Record is generated when input value changes.
Operand On Delta Change
Record is generated when input value changes and the absolute change becomes equal to or higher than the limit value.
