in a GPrs communication mode: led "" lights in case of communication via
GPrs to the monitoring center and goes off briefly during data transmission.
in order to reduce the current consumption, the 5 leds for level of GsM radio
signal can be turned off by removing the jumper to them.
note: on the circuit boards designed to work over GPrs with monitoring cent-
er, the led "" instead of green is blue. in GPrs mode it has the following additional
indications:
- does not glow: no GPrs connection to the server;
- flashes: there is a link to the server, but there is a discrepancy in the identi-
fication codes: serial number, id code of the module, encryption;
- Glows constantly: GPrs connection to the server is undamaged;
- shortly off: the module transmits data to the server.
Remote LED for the GSM module mode
- does not glow: the module is not turned on
- flashing: 64ms on / 800 ms off: has not detected a network
- flashing: 64ms on / 3000 ms off: has detected a network
- flashing: 64ms on / 300 ms off: GPrs communication

the green led lights in the presence of ac power.
Configuring
there are two ways to configure the control panel - via Pc and via sMs.
Configuring via PC
configuration is done via a Pc serial coM port, through Hiperterminal or other
communications software with a special signal cable. if the computer does not have
coM port, you can use the UsB port and adapter UsB/rs3. the procedure is as
follows:
. to include the system to a personal computer it is necessary to connect the
signal cable between the respective serial "com" port of the computer and commu-
nication connector "Uart" on the PcB. on the computer is started terminal software
with speed 38400 bps, no flow control. the echo is better to be off.
. the signal cable converts the rs-3 or UsB interface of the Pc to Uart.
the wires are as follows:
- power V, coming from the module; for the UsB cable it is not nec-
essary
- tx of the module (Uart);
- rx of the module (Uart);
- a signal ground - from the antenna connector.
