configures the device so that with active input 1 it sends a message in which the current supply voltage
is specified. This message could then look like this (example value):
"Supply = 11,712V".
6.3 Format of SMS Commands
In order to avoid unauthorized usage, every configuration command to the STD35 must start with a 4-
digit password.
In the default factory settings, this password consists of the last 4 digits of your
device’s IMEI. This IMEI (International Mobile Equipment Identity) number can
be found on the back of the unit.
If you change this password, you must note that all commands – also reverting to
factory settings – presuppose knowledge of this password. If this is not known,
resetting the password is only possible by using the USB interface.
All commands (except R: and ST?) must end with a full stop “.”!
All commands can be sent in one SMS; each command has to be separated from the next by a full stop
(see examples in Table 9).
If you need a full stop "." in a parameter as it is for example in an E-Mail address or in some APN-
settings, the complete parameter has to be put into inverted commas (“...”) (e.g. "[e-mail]"),
as otherwise the "." would be seen as the end of the command.
Parameters for representing seconds (e.g. command “O1:xxxxx.”) can have 1-5 digits. Valid parameters
are e.g. 1 (for 1 second), 90 (for 90 seconds) or 99999 for (99999 seconds). No leading “zeros” have to
be added. Example: “O1:110” stands for 110 seconds.
Please observe the difference between the figure ‘0’ and the letter ‘O’!. (“O1ON.”
Contains twice the letter O; “V1:0.” contains once the figure 0)
6.4 Explanation of the commands
Switching outputs via SMS
 After the STD35 has received an SMS with the text “O1ON.” (Output 1 ON) from the configured
mobile phone, the relay 1 switches for one second. With the SMS “O2ON.” relay 2 switches for one
second.
 To get feedback of the actual status of the inputs and outputs just send an SMS with “ST?”
Configuration-SMS (Attention: 4-digit keyword is required!)
 The SMS “R:” sets the STD35 back to the factory settings. Please note that this SMS can be sent from
any mobile phone as long as the 4-digit keyword is known. This ensures that the STD35 can still be
used even if the original Master Mobile (phone number) is no longer available.
 You can activate or deactivate the Start-up SMS (START-UP ALARM) with the SMS “S:x.” (x = 1 or 0).
