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).
Antenna is connected to the
MT-301/302/303/304
module using SMA socket located on
front panel.
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.
6.2. First configuration
First configuration of
MT-301/302/303/304
is necessary for setting up basic parameters
making logging to GSM network possible and, optionally, servicing GPRS.
ATTENTION!!!
Since a new module or a module configured for other circumstances
may not have necessary data for proper login to GSM network, it is
necessary to perform the first configuration in local mode by serial
RS232 cable connected to Port1.
To configure the module, connect it via RS232 cable to a computer running
MTManager.
Comprehensive information about installation, use and attachment of
MTM
program to
configured modules can be found in
MTM User Manual.
