Module
2.5 Configuring
Switching several digital outputs at the same time
To set all digital outputs (DOs) simultaneously, send the SMS text "wmdoxxxx
" to the
module.
The module then sends a confirmation message, to the sender only, containing the statuses
of the outputs: „status DO1=x, DO2=x, DO3=x, DO4=x"
Each x stands for the respective output's status: 0 = Off, 1 = On, 2 = no change and 3 =
change over.
Sending the SMS text "wmdo0123" to the module produces the following result:
● DO1 is set to 0
● DO2 is set to 1
● DO3 is not changed
● DO4 switches over its status (i.e., depending on the original state, from 0 to 1 or from 1 to
0)
Using the pulse function
The digital outputs can be activated for a time from 1 to 36000 seconds. When the command
is received, the DO switches to 1 and then back to 0 after expiry of the set time. You address
the pulse function by way of the command for setting a single output followed by a 't' and the
time in seconds. For example, if you send wdo1t10, DO1 is activated for 10 seconds.
The pulse function sends 2 messages, one at the start and one at the end of the sequence.
Reading out digital outputs
To query the status of a single digital input, send the "rdon" SMS to the module, where 'n' is
the number of the chosen digital output.
The module responds with: „status DOn=x".
If a user-defined name has been assigned to an output, you can select this output by putting
the name between asterisks. For example, the status of an input called 'Light' can be queried
by sending the SMS text "r*light*". The module responds with: "status light=x"
Send the "rmdo" SMS to the module to query the statuses of all digital outputs.
The module responds with: „status DO1=x, DO2=x, DO3=x, DO4=x".
Switching in response to a call (RING)
This function enables you to switch over one or more digital outputs (DOs) in response to a
phone call (RING command). If one of the users selected on the "Settings" tab dials the
module's number, it switches over all selected DOs and interrupts the connection.
The caller then receives an SMS text containing the new statuses of the DOs.
If the output's timer function ("output timer") is set to a time greater than 0, the digital output
is set to 1 for the set time (in seconds), after which the output returns to 0.
If the output is already set to 1, it is kept at 1 for the set time and then returns to 0.
To deactivate the output timer function, set the time back to 0.
