relay is not specied in the programming command. The codes can be 4 - 8 digits in length.
The following texts can be used to program temporary access codes.
1111TMP”code”12,Tnnn Store temporary code in the next free memory location, where code = 4 - 8 digit access code, the
number 1 and/or 2 is the relay to activate and where nnn = the no. of hours between 1 - 255hrs
that the code is valid for. Note that if T is omitted default time T = 8 hours.
1111TMP”code”12,Tnnn? Store temporary code in the next free memory location, where code = 4 - 8 digit access code, the
number 1 and/or 2 is the relay to activate and where nnn = the no. of hours between 1 - 255hrs
that the code is valid for. Also send a conrmation text back to the sender with details of which
relays will be activated. Note that if T is omitted default time T = 8 hours.
The following example shows how to program a temporary access code into the next free memory location:
Example: To program a 6 digit temporary code of 234567 to activate relays 1 and 2 and only be valid for 24 hours, the following text
can be sent to the GSM intercom:
1111TMP”234567”12,T024?
Note that in this example no commas , are required to separate the relay selections, however a comma , is required
between the relay selections and the time period the code is valid for. A ? has been included to receive a conrmation
text. The GSM intercom will reply with the following text:
TMP PIN TMP=234567,12
VIDEX 4G
In this example the reply from the GSM will simply conrm that the temporary code has been stored and which
relays the code will activate.
IMPORTANT NOTE: Remember that the maximum number of temporary codes that can be stored is 32. In the event that the
temporary codes validation expires the GSM intercom will delete the code from the memory.
FIND AN ACCESS CODE FDC
The nd an access code feature allows the user to search and nd the memory location (between 000 - 399) of where an access
code is stored in the GSM intercom. It locates the memory loaction using the full 4 - 8 digit access code length (see the following
example). The following text message can be used.
1111FDC”code”? Find the memory location where the 4 - 8 digit access code is stored, where code = 4 - 8 digit
access code. Send a conrmation text back to the sender.
Example:
Find the memory location for the access code 54321, the following text can be sent to the GSM intercom:
1111FDC”54321”?
The GSM intercom will reply with the following text:
STORED IN nnn
VIDEX 4G
where nnn = memory location (000 - 399) of where the access code is stored. In the event that there is no access
code stored the GSM will reply with the following text:
NOT FOUND
VIDEX 4G
IMPORTANT NOTE: When using the FDC feature to locate an access code the full 4 - 8 digit code length is required. A partial
access code cannot be used for the search otherwise the GSM will reply with NOT FOUND, as shown in the example above.
If the FDC feature is used to locate a temporary code, as before the full 4 - 8 digit code length is required for the search. If
the temporary codes validation has not expired the GSM will reply with a memory location between 400 - 431 of where the
temporary code is stored. If the temporary code validation has expired the GSM will reply with NOT FOUND, as shown in the
example above, since it would have already been deleted automatically after the validation has expired.
DELETE AN ACCESS CODE WITHOUT KNOWING ITS LOCATION DEC
This feature allows the user to delete an access code (including temporary codes) without knowing the memory location of where
it is stored. The feature uses the 4 - 8 digit code length to search through the memory locations where the code is stored and then
deletes it from the GSM intercom. The following text message can be used.
1111DEC”code”? Find the access/temporary code and delete, where code = 4 - 8 digit code length, also send a
conrmation text back to the sender.
Example:
To delete an access code of 87654321, the following text can be sent to the GSM intercom:
1111DEC”87654321”?
