Longo programmable controller LPC-2.C05
1 DESCRIPTION
LPC-2.C05 module is used for communication with mobile GSM equipment, like GSM phone or GSM
modem. The communication between LPC-2 system and mobile equipment is established through
SMS messages.
Up to eight digital and eight analog values could be represented from LPC-2 system as well as up to
eight digital and eight analog commands could be sent from GSM phone or other mobile equipment.
This commands could act direct to digital and analog outputs or can be used for parameter settings.
LPC-2 system can works also in alarming mode, where SMS alarm message is sent in case of
abnormal situation (temperature too high, water leakage, etc.). The SMS alarm messages are sent
recurrently every hour on first three phone numbers stored on the SIM card. If the phone numbers
are stored in the international notation (with country code) then the prefix must start with “
00

a) LED1 blinks once after reset and then is off – SIM card not inserted or SIM card PIN still enabled
b) LED1 blinks once after reset and then is on – GSM network problem; check antenna and GSM signal
level with the mobile phone
c) LED1 blinks once after reset and then start blinking – normal starting sequence; everything OK
IMPORTANT: The PIN number of the SIM card must be disabled otherwise LPC-2.C05 will not be
connected to the GSM network!
