4. OPERATION
4.1 Switching On the Modem
The first time power is supplied to the MTX-IND-V2 terminal (pin 1 & pin 2 terminal block connector), it will
switch on.
The modem is fully operational after 4 seconds. Logging onto a network may take longer than this and is
out of the modem’s control.
4.2. Automatic restart after shutdown:
This allows the terminal to always be switched ON and to be able to restart by itself. The terminal will be
powered up 100% time if power is applied.
4.3. Operating States/LED
The modem has two LEDs, both for status indication.
The POWER LED DLP1 displays if power is applied and if the
internal power supply is working.
The SYNC LED can be operated in two different display modes:
AT^SSYNC=1 or AT^SSYNC=
2 (factory default).
mode
LED Status
AT^SSYNC=0
SYNC mode:
Enables the SYNC pin to indicate growing power consumption during a transmit burst. You can
make use of the signal generated by the SYNC pin, if power consumption is your concern. To
do so, ensure that your application is capable of processing the signal. Your platform design
must be such that the incoming signal causes other components to draw less current. In short,
this allows your application to accommodate current drain and thus, supply sufficient current
to the GSM engine if required. Note: <mode>=0 is the factory default of the TC65i module.
AT^SSYNC=1
LED mode:
Enables the SYNC pin to drive a status LED installed in your application
The coding of the LED is described in the following section, ME status indicated by status LED
patterns.
AT^SSYNC=2
LED mode:
Like <mode>=1, but, additionally, enables different LED signalization in SLEEP mode
depending on the status of PIN authentication and network registration.
Note: <mode>=2 is the factory default of the MTX-IND-V2 Terminal.
