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.

Current Value

If the device is connected to the Telematics Configuration Tool, 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 I/O elements with Low priority are enabled: Total odometer GSM Signal, Battery Voltage, Battery Current, PCB temperature, GNSS PDOP, GNSS HDOP, Ignition, Movement, External voltage.

These records made by FTC134 device 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, FTC134 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 Monitoring

No event at all. Values are recorded only when other triggers worked.

Operand On Change

Record is generated when input value changes.

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 On Hysteresis

Record is generated when input value crosses the high limit value from below the low limit value or vice versa.

Operand On Delta Change

Record is generated when input value changes and the absolute change becomes equal to or higher than the limit value.

Permanent I/O

When no permanent I/O elements are 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.

General I/O Settings

When a device has at least one DOUT, the "General I/O Settings" menu button is displayed on the top right. This menu allows configuring general settings for DOUTS. Select a particular DOUT and configure its settings.

Overcurrent recovery

Parameter ID = 350

The feature will attempt to recover DOUT state when an overcurrent is detected in the circuit.

Principle of recovery: The DOUT is toggled to HIGH and the device checks whether the overcurrent event is still present. If yes, DOUT is toggled to LOW. This toggling to HIGH and LOW have the duration of ~2 ms and ~3 ms respectively, thus the whole cycle takes ~5 ms. This is repeated until the overcurrent event is no longer detected or the maximum number of attempts (1000) is reached (takes ~5 seconds in total).

Inversion

Parameter ID = 360

This feature inverts the digital output value. All scenarios and commands will have an inverted effect for the digital output. For example, when DOUT is inverted - it will be ON by default and triggering any scenario will turn it OFF.

Normal behavior: DOUT ON - HIGH (1), DOUT OFF - LOW (0).

Inverted behavior: DOUT ON - LOW (0), DOUT OFF - HIGH (1).

IMPORTANT! DOUT state I/O element that is sent in the records represents the real state of the DOUT pin.
