Scooter Protocol

TST100 designed to work with Segway Ninebot ES4. Segway MAX Xiaomi M365 and Fitrider e-scooters. When configuring TST100 device set correct "Scooter Protocol" for the e-scooter you using. This is necessary for correct communication between TST100 and e-scooter.

E-Scooter I/O

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 of measurement.


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 FMB120 are regular, and regular packets are sent as low priority records. Priority level (AVL packet priority) can be:

  • 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, FMB120 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.


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.

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:

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


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.
