2.8 Finding a Number in the Memory
When a large number of numbers are stored in the memory using the LIST command can
be impractical. To find whether an individual number is stored in the memory the master
user sends the following command to the board:
QUERY<space>number. or
QNUM<space>number
NB the number should be the full number (not the 8-digit truncated number)
If the number is present the LED will flash 4 times and if not in the memory the LED will light
twice for 2 seconds. If TEXTRES is enabled an SMS text message will be sent with the result.
2.9 Clearing All Numbers and Settings
The CLEAR ALL command is used to erase all stored user and master numbers. To erase
all numbers the following SMS text message is sent by a master number:
CLEAR ALL
No response is sent by the system to acknowledge the command. This does not affect
the customisable input text messages.
2.10 Result Acknowledgement Message
The system can be setup to send a SMS text message to acknowledge a command. This
acknowledges the result of the last command processed such as adding a new user
number. The SIM card in the system must have sufficient credit for sending SMS text mes-
sages. To enable/disable the service the following text message is sent by the master
number:
TEXTRES enable (or also valid: TEXTRES e)
TEXTRES DISABLE (or also valid: TEXTRES d)
The result message ‘Operation Successful’ is sent when the service is enabled
3 Relay Operation/Access Control
3.1 Enabling Any Number and Disabling Open-on-Call
The system can be setup to allow any number to operate the relay output. To enable
any call the CALL command is used with the action ANY and is sent by the master phone
in the following format:
Call any
To return the system to operate from only valid user numbers the LIST action is sent with
the CALL command as follows:
call list
