converter
The connection is based on an RS232 connection to a GSM modem via the service port on the unit. Since
the connection on the controller is a TTL communication, the interface box PI-1 (option J5) is needed to con-
vert the signals to RS232. The PI-1 connects via a cable with SUB-D 9-pin female connector on the modem
side (see illustration above).
Modem type
DEIF recommends using a Westermo GDW-11 modem, as the application has been tested with these termi-
nals. The SIM card needed must support data transfer. Contact your GSM provider for details. The easiest
way to set the PIN code in the modem itself is to mount the SIM card in a mobile phone and change the PIN
code there. The SIM card will remember the PIN code when it is installed in the modem.

*After each auxiliary supply power up, the unit will send the required PIN code to the modem if this is neces-
sary. The PIN code is adjusted in the PC utility software.
For calling a foreign number, type "+" and country code instead of "00", for example dial +45 99999999 for a
Danish number.
Alarm during operation
Should an alarm occur during the interruption, the controller unit will re-transmit it when the modem starts
again, so no messages are lost.
