6. Respond messages
This chapter shows you how to read and understand the different response messages sent from GC-101. When GC-101
is in GPRS/SMS mode it will upload the data to the assigned URL first. However, if GPRS service is not available, it will send
the SMS to the predefined phone number instead. In the case of GPRS-only mode, GC-101 will only send the data by GPRS
no matter there is GPRS service or not. Basically, there’re 6 different situations that trigger the GC-101 to response its
position (
Auto Report, Polling, Emergency, Move, Geofence, Park
) and are shown in the following pages.
Event Table:
This event table helps you to know what event triggers the response.
Note: When GC-101 experiences the low battery power, it will send an SMS to the 1
st
phone
number in the phonebook. The message will be
“username, Device Power low,
Check/recharge”.
It will send a second SMS when the power is really too low. The
message will be
“username, Device Power too low, recharge battery first”.

Auto
When the monitor sends a valid Auto Report command to GC-101, it will send a report including an “Auto”

SOS
When the user presses the Panic button, it will send the report including an “SOS” event behind each
