SMS COMMAND LIST section
.
Module configuration can be performed over TCP or via SMS.
Configuration parameters and modes are described in “FM4100 FM2100 and FM2200 Protocols”
document.
4.2
Sleep mode
FM2200 can enter sleep mode (standby mode) under two conditions:
FM2200 does not detect movement.
FM2200 does not send or receive any data for 5 minutes. This means that if coordinate
recording interval is less than 5 minutes, FM2200 will never go to sleep mode.
FM2200 exits sleep mode when it detects movement again.
While in sleep mode, FM2200 sets GPS receiver to sleep mode, therefore it does not record or
send any data. The power usage also decreases saving vehicle‟s battery.
4.3
Virtual odometer
Virtual odometer is used to calculate traveled distance in FM2200 as a separate I/O element.
When FM2200 detects movement, it starts counting distance using GPS signal: every second it checks
current location and calculates distance between current and previous point. It keeps adding these
intervals until it is time to make a record, then FM2200 records its location and adds odometer value,
which is equal to the sum of all distances, measured every second. When record is made, odometer
resets to zero and distance calculation starts all over again. Note, that FM2200 does not measure
distance between coordinates, that it records using time, distance or angle change intervals. Instead, it
uses virtual points, which are established every second, and calculates distance between them.
