FMC225 I/O settings
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 FMC225 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, FMC225 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.
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%.
NOTE: Average Constant is not used as an activation timer or delay timer. But it is used as a filter.
Event is generated at different times due to variations in voltage. Average constant is designed to filter jumps instead of event generation time.
For example: generation is set to happen at 14500mV, and actual voltage is set to 15000mV, that record will be generated earlier than 10s with avg const set to 100. This is because avg const is calculating time it takes for device to get to actual voltage (in this case 15000 mV), while device will be generating records when it hits 14500mV.
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

If FMC225 is in Deep Sleep or Ultra Deep Sleep mode and an SMS event occurs with Low priority (which does not wake up FMC225), 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. |
FMC225 RS-232/RS-485 parameter configuration
FMB-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:
