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.

Input Name

I/O element name.

Current Value

If device is connected to Configurator all current I/O values are displayed in this column. Also I/O current values can be seen in Status→I/O Info tab.

Units

Units of measurement.

Priority

This field allows to enable I/O elements and setting them a priority so they are added to the data packet, which is sent to the server. By default 12 I/O elements with Low priority are enabled: Ignition, Movement, Data Mode, GSM Signal, Sleep Mode, GNSS Status, GNSS PDOP, GNSS HDOP, External Voltage, Speed, Battery Current, Battery Voltage. All records made by FMM125 are regular, and regular packets are sent as low priority records.

Priority level (AVL packet priority) can be:

None Priority

Module doesn't make additional record.

Low Priority

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

Module makes an additional record with High priority flag and sends event packet immediately to the server using GPRS.

Panic Priority

This priority triggers same actions as High priority, but if GPRS fails, it sends an AVL packet using SMS data if SMS data sending is enabled and the number is provided in SMS/Call Settings.

High and Low Level

These levels define I/O value range. If I/O value enters or exits this range, FMM125 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.

Fmb120 on entrance.png

Operand On Both


Record is generated by both On Exit and On Entrance operands' logic at same time.

Fmb120 on both.png

Operand Monitoring


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

Fmb120 operand monitoring.png

Operand On Hysteresis


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

Fmb120 on hysteresis.png

Operand On Change


Record is generated when input value changes.

Fmb120 on change.png

Operand On Delta Change


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

Avg Const

If Avg Const value is 10, new value must be present for 1 second to register the change to a new value. Internal sampling is done every 40 ms, so 25 samples are taken per second. To configure 5 seconds of averaging multiply 10 by 5 yielding 50 as Avg Const value. The same logic works if the device is in Deep Sleep mode.
Averaging follows RC exponential curve, see image below:

Fmb120 avg const.png

For Boolean values of 5τ, values is used, that means value change is taken when new values is averaged to more than 99.3%.

Send SMS To

Sends SMS notification about event to selected number from SMS/Call Settings GSM Predefined Numbers list if event priority is set to Low, High or Panic.

SMS Text

The SMS Text field can be altered and any text can be entered. Maximum message length is 160 symbols (numbers, letters and symbols in ASCII, except for comma “,”).

SMS Event Text may be either in default or composed format.

Default format:

Date, time, longitude, latitude, 'SMS text', value

Example:

2018/11/02 12:00:00 Lon:0.000000 Lat:0.000000 Alarm 1

Composed format:

Composed format may consist of text and defined commands which start with % symbol.

Alert.png
If FMM125 is in Deep Sleep or Ultra Deep Sleep mode and an SMS event occurs with Low priority (which does not wake up FMM125), then the device does not send the message. It is saved to device memory until it wakes up from Deep Sleep or Ultra Deep Sleep mode and GSM modem starts working normally. After it wakes up, all the messages that are saved to memory will be sent, but keep in mind that only 10 messages can be saved to memory – all other messages will not be saved, until there is free memory space.

FMM125 RS-232/RS-485 parameter configuration

Fmb125 uart mode.png

FMM-125 supports RS-232 and RS-485 serial standards and can be configured to work in different RS-232/RS-485 modes. More information about each mode is provided in RS-232 and RS-485.
Only one mode may be selected at a time:

  • Disable - Disable RS-232/RS-485 functionality;
  • RS232 - Select RS-232 functionality;
  • RS485 - Select RS-485 functionality.

RS-232 modes


RS-232 supports following modes:

  • Log Mode – suitable for debugging/logging;
  • NMEA – NMEA logs are transferred;
  • LLS – LLS sensor support;
  • LCD – external LCD support;
  • RFID HID – RFID HID reader support;
  • RFID MF7 - RFID MF7 reader support;
  • Garmin FMI – Garmin support;
  • TCP ASCII – for routing any input string from external device to the server;
  • TCP Binary – for routing any binary input data from external device to the server.

RS-232 baudrate and parity

Every RS-232 mode supports different baudrates, but each mode has its own default baudrate value. Default baudrate and parity values for each RS-232 mode are provided in the table below.

Mode Default settings
RS-232 RS-485
Baudrate Parity Baudrate
Log Mode 115200 None 115200

RS-232 TCP Binary mode has additional configurable parameters for advanced data filtering as shown on the right hand side figure.

RS-232 Garmin mode settings

Fmb125 garmin mode.png

Garmin FMI mode has addditional filtering capabilities. It is possible to filter Ping and Unicode packets. If Ping Filter is enabled, then Ping packets are blocked. When Unicode Filter is enabled Unicode packets are not sent to the server. Both filters may be enabled for simultaneous effect.


RS-485 modes


RS-485 supports several modes:

  • Log Mode – suitable for debugging/logging;
  • NMEA – NMEA logs are transferred;
  • LLS – LLS sensors support;
  • TCP ASCII – for routing any input string from external device to the server;
  • TCP Binary – for routing any binary input data from external device to the server.

RS-485 baudrate

Every RS-485 mode supports different baudrates, but each mode has its own default baudrate value. Default baudrate values for each RS-485 mode are provided in the table above.

RS-485 LLS sensors
