Mains adapter: If it fits into the design of your application we recommend the plug-in supply unit
used with the type approved Gemalto M2M reference setup. Ordering information can be found
in
. This 12V mains adapter comes with a 6-pole Western plug and provides an inter-
nal connection between IGT_IN pin and PLUS pin. If there is such an “auto ignition” connection
between PLUS and IGT_IN, the module will restart automatically after a normal shutdown.

Power Up/Power Down Scenarios
In general, be sure not to turn on the Java Terminal while it is beyond the safety limits of voltage
and temperature stated in
. Java Terminal immediately switch off after having start-
ed and detected these inappropriate conditions. In extreme cases this can cause permanent
damage to the Java Terminal.
3.10.1
Turn Java Terminal on
There are various possibilities to turn on Java Terminal and start into normal mode, depending
on connecting and/or operating states.
If powered off (i.e., if Java Terminal‘ power supply is disconnected):
•
Java Terminal can simply be started up by plugging an appropriate power supply unit
between PLUS and GND of the 6-pole Western jack.
If switched off (i.e., while in Power Down mode):
•
Java Terminal can be started up by activating the IGT_IN signal (pin 4).
•
Java Terminal can be started up by activating the RS-232 DTR line (as long as RST_IN sig-
nal (pin 3) is not active (voltage <2V)
•
Java Terminal can be started up by configuring the watchdog appropriately. For details see
.
Note: With an “auto-ignition“ connection between IGT_IN and PLUS, or if employing PoE (see
), Java Terminal will automatically restart into normal mode after switch off (see
). The start up variant from Power Down mode is therefore only applicable if
there is no such “auto-ignition“ connection at the power supply unit.
3.10.2
Reset/Restart Java Terminal
There are various possibilities to reset/restart Java Terminal:
•
Java Terminal can be reset/restarted by entering the command AT+CFUN=x,1. For details
on AT+CFUN please see
.
•
Java Terminal can be reset/restarted by configuring the watchdog appropriately. For details
see
.
•
Java Terminal can be reset/restarted by configuring a wake-up alarm (see
)
before using AT^SMSO to turn them off and send them into Power Down mode.
•
Java Terminal can be reset/restarted by simply shutting them down as described in
and then restarting them as described in
. Note: With an “auto ignition“
