6. Starting the module
Starting
MT-101
module requires few basic activities.
Recommended sequence:
1.
GSM antenna attachment.
NOTICE!
The antenna has to be attached at every power up since it is a necessary
transmitter load.
The module exchanges information with available GSM networks in order
to test availability of performing emergency calls (112) even without SIM
card
2.
Configuration of basic operating parameters
3.
Insertion of SIM card
4.
Restart of the module
6.1. Connecting antenna
Connecting external GSM antenna is an essential condition for proper module operation.
The type of antenna depends on the desired mounting type and power of GSM signal in
antenna placement area. As previously mentioned, the antenna has to be attached at every
power up because it is a necessary transmitter load and absence endangers the module's
transmitter part.
Even with no
SIM inserted, the module exchanges information with
available GSM networks in order to secure possibility of sending emergency calls (112).
The antenna is connected to
MT-101
module via SMA connector placed on the front panel
of device.
The choice of antenna type depends on GSM signal propagation at place where the module
is installed. In most cases, a standard small size antenna is sufficient. Where GSM signal is
weak using multi-segment directional antenna may be necessary.
