Emergency restart:
•
•
In the event of software hang-ups etc. the Java Terminals can be restarted by applying a
voltage >8V to the RST_IN pin (pin 3) for more than 10ms.
The RST_IN signal restarts the Java Terminals.
voltage >8V to the RST_IN pin (pin 3) for more than 10ms.
The RST_IN signal restarts the Java Terminals.
Caution: Use the RST_IN pin only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the RST_IN pin causes the loss of all informa-
tion stored in the volatile memory since power is cut off immediately. Therefore, this proce-
dure is intended only for use in case of emergency, e.g. if Java Terminals fails to shut down
properly.

dure is intended only for use in case of emergency, e.g. if Java Terminals fails to shut down

When the Java Terminals enter the Power Down mode, e.g., after you have issued the
AT^SMSO command or activated the RST_IN signal, all RS-232 interface lines are active for
a period of 50ms to max. 3.5s. This may cause undefined characters to be transmitted on the
RS-232 lines which can be ignored.

Disconnecting power supply
Before disconnecting the power supply from the PLUS pin, make sure that the Java Terminals
are in a safe condition. The best way is to wait 1s after the "^SHUTDOWN" result code has
been indicated.
