LED DIAGNOSTICS
The 6 LED of the GSM module allow for the monitoring of the status of the CALL system:
LED 1 (red):
1 ash every 2 seconds: SIM correctly recorded in the GSM network
2 ashes every second: SIM in the recording mode in the GSM network
LED 2 (yellow):
It ashes rapidly in the transmission phase
LED 3 (yellow):
It ashes rapidly in the receiving phase
LED 4 (green):
Continuous ashing: SIM in the initialization phase
From 1 to 5 ashes, followed by an interval: GSM reception level (1: minimum level – 5: maximum level)
LED 5 (red):
It switches on when an entering command is being processed.
If the credit of the SIM is nished, LED 5 will switch on with xed light.
LED 6 (green):
Switched on with xed light: correct operation of the software
Flashing: error in the software
During normal operation the LED status is as follows:
LED 1: ashing every 2 seconds
LED 2 and LED 3: continuous ashing
LED 4: from 1 to 5 ashes to show reception level
LED 5: switched off (it switches on if an SMS is received)
LED 6: switched on with xed light
ACCESS PASSWORD
All programming controls provide for an access password.
For safety reasons, the rst operation to be carried out is to change password.
Send an SMS message with this text:
modpsw 123456 112233
where:
modpsw command string
123456 default password (or password currently in use which you wish to change)
112233 new password (max 10 numeric characters). When a new password is set,
the old one will no longer be valid.
REPLY:
“PASSWORD UPDATED ”
The default password can be restored by resetting the SIM.
The type of password typed in also selects the operating mode (Safety Access or Open
Access).
If the rst gure of the password is different from “0” (zero), the system sets in Safety
Access mode.
If the rst gure of the password is “0” (zero), the system sets in Open Access mode.
