1 Description

1.1 Summary

The GSM-PRO2(E) is a compact remote control and messaging system. All IOs are monitored by SMS and email
and controlled by SMS communication through the GSM network.

The module can be configured with the GSM-PRO2 PC-software. Each IO can be modified by user-defined
parameter names and messages. A selected group of users can be chosen from the phonebook to control the
module, or only receive messages.

On each defined input status change (rising or falling flank for digital inputs or reached level for analog inputs)
the module sends a pre- or user-defined message to the selected group of users.
The outputs can be set when a selected user sends a pre- or user-defined SMS to the GSM-PRO2(E).

The GSM-PRO2(E) sends a periodical message on user defined times. On power loss the module holds enough
power to send SMS messages to a selected group of users. It also sends messages when coming back from a
power reset.

1.2 Module types

The GSM-PRO2 consists of the modules as described below. For images and connection examples in his
document the outline of the GSM-PRO2 is used.

When referring to a GSM-PRO2(E) in this document it is recalled as ‘the (a) module’.

The GSM-PRO2(E) comes in 2 variations: with or without GPS.

9 I/O configuration and messaging

The module responds to read and write commands. Commands are preceded by an ‘r’ for read and ‘w’ for write
actions.
All SMS commands are NOT case sensitive.

9.1 Digital Output

9.1.1 Configuration

The following items can be configured with the software:

 Name
 After setting the digital output the module sends a confirmation message according to the configured

rise or fall message. This message is sent only to the sender of the message.

 Send only the user defined text, this sends only the text defined in the message box, no module name,

IO name and timestamp.

 Define your own instructions to control the output.
 Activate or toggle the output when starting a phone call with the module.
 Link DO to UI
 Activate when GSM connection lost, deactivate when GSM connection returns.
 Preserve or deactivate the status on restart or power cycle.

9.1.2 Select users

The recipients have access to the associated digital output.
NOTE: Selected DO users do not have any rights to send other commands to the module other than addressed
to the defined output.

9.1.3 Messaging

It is possible to send self-made instructions or use the pre-defined instructions for the output. With these
instructions the output can be activated, deactivated and activated for a given period of time (one-shot).

9.1.3.1 Number ID

The number ID for setting the digital output can be disabled. When disabled the output responds on both SMS
and incoming calls from everyone.
NOTE: keep safety precautions in mind when disabling this function together with the ring function due to
unwanted incoming calls.

9.1.3.2 User defined instructions

Use a self-made instruction to control the output. E.g. you may want to use the instruction pumpon to activate
the output, and pumpoff to deactivate.

9.1.3.3 Change the digital output status

To set a digital output (DO) send the following default message: wdonx, where x is the state.
E.g. when you send wdo11, DO1 is set to 1.

If set, the module sends a confirmation message: ‘status DO1=x‘. If the output state is already in the state, the
text: ‘status not changed’ is added to the answer.

GSM-PRO2

- 20 -

9.1.4 Using the one-shot function

The digital outputs can be set for a given time from 1 to 10 hours. When this command is received, the DO sets
to 1 and after the number of seconds the DO falls back to 0. The one shot function is called by selecting the DO
followed by a ‘t’ for time and the time in seconds. E.g. when you send wdo1t10 the DO is set for 10 seconds.
The one-shot function sends two answers, one at the start and one at the end of the sequence.

NOTE: see user defined functions to define own instructions.

9.1.5 React on RING

This function enables toggling a DO on a RING (phone call) command. When one of the selected users in the
settings tab dials the number of the module it toggles the DOs and breaks the connection. The caller receives a
SMS message with the status of the DO.

When the output timer value is set the output status is set to 1 for the amount of seconds set. If the output
status is already 1 this is kept for the amount of seconds and then set to 0.

Clear the output timer value in the user interface to disable the timer function.

9.1.6 Link DO to UI

The first DO can be linked to the first UI, the second DO to the second UI and so on. When a status change on a
DI1 is detected the DO will adopt this status.
The status of the DO can always be overruled by an SMS message setting the output(see above). If the output
has already the same state as the linked input the output will not change.

When the UI is set to analog the DO status is 0 when the AI status is normal. The DO status is set to 1 when the
AI status is either low or high.

NOTE: This function can conflict with the SMS and RING instructions.

9.1.7 Activate when GSM connection is lost

Select to activate an output when the GSM connection is lost. The output deactivates as soon as the GSM
connection is re-established.

NOTE: This function can conflict with the SMS and RING instructions.

9.1.8 Preserve status on startup

Choose if the status of the output is preserved on restart or power cycle. If deselected the output will be
deactivated.

9.1.9 Wiring example

In the following example the DO is connected as normally open.

GSM-PRO2

- 21 -

9.2 Universal Inputs

The universal inputs can individual be configured as:

 Analog input AI (0..10V or 0..20mA)
 Digital input DI (default)

The selected button represents the chosen function and is set after uploading.

9.2.1 Select receivers

The recipients receive the messages of the selected UI.

NOTE: Selected UI users do not have any rights to send commands to the module.

9.2.2 Confirmation sequence

When the confirmation is enabled, the module sends the message to the selected users one by one with an
adjustable interval delay.
E.g. the sequence starts, the first phone number is addressed. When the delay time has expired, the next
phone number in the list is addressed, and so on until the last phone number in the list is addressed.
This can be repeated for selected number of times before the module stops the sequence.

The user who receives the message is able to stop the confirmation sequence by sending a chosen text (can be
left blank) to the module before the delay has expired. The module answers: ‘Confirmation ended
<timestamp>’

NOTE: When a new status is reached on the UI, a new sequence is started and the old sequence is stopped
automatically.
When there are one or more email addresses in the user list, the email is sent only once to all email addresses
at the beginning of the sequence.

9.3 Analog inputs

Each analog input (AI) represents a scaled value from 0 to 100% (10V or 20mA). Within this scale threshold
values can be monitored.

9.3.1 Configuration

Configure the following items:

 Name
 The unit for the input feedback. E.g. litres (Ltr) or kilograms (kg).
 Log this AI at a pre-set interval, see for interval settings.

GSM-PRO2

- 22 -

 The min. value represents the scaled value for 0V
 The max. value represents the scaled value for 10V or 20mA
 Lower limit threshold
 Upper limit threshold
 Minimal change (hysteresis)
 Send only the user defined text, this sends only the text defined in the message box, no module name,

IO name and timestamp.

 The Analog Inputs can generate messages including value and unit when:

- The upper limit + hysteresis is reached

- The lower limit – hysteresis is reached

- The status recovers between the upper and lower limit +/- hysteresis

NOTE: The min./max. and threshold/hysteresis values are limited to 5 digits with a maximum of 2 decimals.

A delay in seconds can be set which a changed AI has to exceed before it is accepted, during the delay the UI
led blinks. If the status of the delay is changed back again to the previous state before the delay is expired the
change is discarded.
Clear the delay to disable detection delay.

9.3.2 Wiring example

In the following example Ai1 is connected to an analog source.

9.4 Digital Inputs

The Digital Inputs can generate messages when:

- A rising flank is detected: the status changes from 0 to 1

- A falling flank is detected: the status changes from 1 to 0

9.4.1 Configuration

Configure the following items:

 Name
 Rising / Falling flank message
 Send only the user defined text, this sends only the text defined in the message box, no module name,

IO name and timestamp.

 Rising / Falling flank message delay: the changed status must be held for the given time before being

accepted

9.4.2 Wiring example

In the following example DI1 is connected to be pulled-up with +V.

9.5 Counter

The module has in input which can count up to 1000 pulses per second. The module can send messages on a
given threshold. It can also log the counter values for each day.

Configure the following items:

 Activate Counter
 Name
 The unit for the feedback. E.g. Kwh
 Puls pro Einhet; E.g. when 100 pulses represent 1Kwh and a feedback or measurement is only wanted

for Kwh and not the actual pulses.

 Threshold value; the module sends the configured message every time the threshold is reached
 Counter message; the message for the threshold
 Clear after send; the counter is cleared after sending the threshold value
 Send only the user defined text, this sends only the text defined in the message box, no module name,

IO name and timestamp.

 Daily log; Logs the value between midnight and midnight
 Clear after Log; Clear the counter after logging the value

To request the actual Counter value send an SMS with the text ‘CNT’. The module answers with the counter
value and unit, the value of the current day and the counter start timestamp.

To reset the counter send an SMS with the text ‘CLRCNT’.

9.6 Read all IO statuses

To retrieve the status of all IOs send: rall. The module answers: With the module name and the status of all IO’s
and extensions.

To send the full IO status to an email address send: rall<email>.

9.7 Link multiple modules

It’s possible to link multiple modules by SMS. By selecting the ‘send only user defined text’ in the IO
configuration it’s possible to send the pre-defined messages to other modules.

For example: digital input 2 sends WDO11 on a rising flank to a second unit. This unit receives the message,
set’s the digital. On the falling flank the first unit sends WDO10 to deactivate the digital output on the second
unit.
It is also possible to send an SMS to itself and activate digital outputs on reaction to digital inputs.

NOTE: The digital outputs cannot parse any messages. They only respond to their sender.

9.8 IO operating hours counter

The IO operating hours counter sums the total time the IO is in HI state. The counter can be turned on/off each
individual digital in- and output. The counted value can be added to the periodical message and ‘RALL’.

Counters are limited to 17500 hours (+/- 2 years).

NOTE: make sure to keep all IO’s in LO state when configuring the counters due to faults in starting time.

9.8.1 Digital output counter

To retrieve the counter value of an individual digital output, send: timedo1, where n is the number of the
requested digital output.

To retrieve the counter value of all digital outputs send: timedo0.

To reset the counter value of an individual digital output, send: clrtimedon, where n is the number of the
requested digital output. To reset all counter values of the digital outputs, send: clrtimedo0

9.8.2 Digital input counter

To retrieve the counter value of an individual digital input, send: timedin, where n is the number of the
requested digital input.

To retrieve the counter value of all digital inputs send: timedi0.

To reset the counter value of an individual digital input, send: clrtimedin, where n is the number of the
requested digital input. To reset all counter values of the digital inputs, send: clrtimedi0

10 Extensions

The number of IO on the module can be extended with external modules. These are connected with a bus
driven interface by simple pushing the modules into another with the connector on the left side of the module.

10.1 Configuration

10.1.1 Hardware

To adjust the bus address on each extension lift the lid with a small flat screwdriver and turn the rotary switch
into the wanted position: address 00 to 99.

NOTE: each extension has to be configured with an unique address.

10.1.2 Software

Configure the extension(s) for the module by clicking IO->Extensions. Click the ‘Add’ button to add a module.
Fill the bus address as adjusted on the extension and choose the type of module. Click ‘Add’ and the module
appears in the list. Repeat this step for the number of extensions connected to the module.

Each added module can be configured with a module name and up to 10 users who have access to the module
in case of outputs, or receive messages in case of inputs.

NOTE: Failure on Extensions are sent to the users in the general message tab.

10.2 GSM-PRO-4DO

The 4DO has 4 CO output. The following items can be configured with the software for each output:

 Output name.
 Confirmation message for falling and rising flank.
 User defined instructions to change the status on or off.

To change the output status by a default message SMS: WDOnxEa where n is the output number, x the status
and a the bus address.

NOTE: you can set multiple outputs with one SMS when they have the same user defined ON or OFF
instruction.

In the following example Do1 is connected as normally open and Do4 is connected as normally closed.

Connect only to a single polarity supply! The following examples are not allowed:

10.3 GSM-PRO-10DI

The 10DI has 10 digital inputs. The following items can be configured for each input:

 Name; default set as DI1 to DI10.
