5. Safety Information This GSM module left the factory in perfect condition in terms of safety engineering. The user must observe the safety instructions and warnings contained in these operating instructions to preserve this condition and to ensure safe operation. Please read the operating instructions completely before commissioning. They contain important information for correct operation.
6. Operating conditions • The GMS module must be operated at direct voltage between 5 - 30 V/DC. • For operation free of defects, the power source must be able to deliver a current of at least 1000 mA without voltage drop. It is not important whether supply is provided by a rechargeable battery (e.g. solar rechargeable battery) or a suitable mains adapter with stabilised output. • When installing the GSM module, ensure a sufficient cable cross-section of the connection lines.
. Output Function Overview The GSM module has 14 outputs to which one red LED for status display is connected each. Each output is assigned a specific function or input signal. The GSM module has the following outputs: • The „Incall“ output can be switched via an incoming call. For this, the GSM module already has a relay firmly assigned to this function. The relay has a potential-free contact (for max. permissible load values see chapter „Technical Data“) and is activated by incoming call.

Outputs (see figure 1, items 8 to 15): A relay is already installed to the „INCALL“ output (see figure 1, item 8) and the output „SMS1“; it can be used to switch 8 A at 250 V/AC or 30 V/DC. Minus/- is connected to the left screw terminal and Plus/+ to the right terminal. A relay (Conrad item no. 502892) or the relay PCB (Conrad item no. 585498) can be directly connected to the screw terminals. Red LEDs are applied to all outputs.
10. Required Steps and Information for Commissioning Important! To take the GSM module into operation properly, the following steps must be performed strictly in the indicated order. Non-observance may lead to functions not being warranted, configuration being impossible and/or the SIM card being locked by the GSM module. a) Software Installation Before taking up any work at the GSM module, you have to install the control software and the required drivers on your computer.
c) General Settings of the Control Software Use the button „D/E“ to switch the program language between German and English in the control software. The help file is opened in the corresponding language. Click the button „General Settings“. An interface appears for entering the SIM card’s PIN number, the desired phone numbers (PHONE) and email addresses (MAIL). Also observe the notes and figures in the chapter „Initial Commissioning of the GSM Module“.
g) Email with SMTP and GPRS For sending emails, you have to indicate the GPRS settings of the provider of the inserted SIM card. If you indicate your provider in „SIM“, the right GPRS connection and IP address are set automatically. If your desired setting is not among these, enter it at „other providers“. The SMTP mail outbox must be entered in „SMTP“ (e.g. smtp.web.de). Additionally, the port number must be entered. Most freemail providers require port number 25 to be entered.
11. Initial Commissioning of the GSM Module (Test Configuration) At initial commissioning, observe that the removed PCB is not short-circuited by metal or live parts. When connecting the operating voltage, always ensure correct polarity. Avoid short circuits at the GSM module connections. If this is not observed, the GSM module will be destroyed. In such cases, any warranty/guarantee will expire! We recommend the easiest possible configuration for initial commissioning.
• Switch on the supply voltage now. • Start the GSM module control software on your computer. Select the COM port determined in your operating system’s device manager in the software under „Communication“. • Then click „Status“ and check whether a connection has been established. The GSM module has to indicate that the „PINCODE“ is not correct yet („PINCODE FALSCH! WARTE AUF DATEN“ = „WRONG PINCODE ! WAITING FOR DATA...“). • Now enter the „PINCODE“ in the control software under „General Settings“.
• Send the change to the module in „Communication“ (click the button „Send“). • The message „All data transferred!“ must appear. • Switch off the operating voltage again. • The saved data is preserved in the module even after switching the operating voltage off and on again. • To permanently save the input in the control software on your computer, click the button „Save“. • Now insert the SIM card. For this, push back and open the lock of the SIM card holder on the rear of the PCB.
Due to the great number of SIM cards and providers on the market, you may receive the message „Wrong pin code! Waiting for data“ in the status window in spite of the SIM PIN being set correctly and the configuration being transmitted correctly. In this case, take a different provider’s card, perform the required changes to the configuration according to the instructions and test the GSM module again. If this does not work, use the contact information listed in item 1 of these operating instructions.
12. General Information on the „Status“ Button The module performs a reset and dials into the GSM network once a configuration has been transferred to the GSM module. Once the green GSM LED flashes slowly (LED on for 1 second, then 3 seconds break), the status of all inputs and outputs can be displayed in „Communication“. • For this, set the COM interface recognised in the device manager. • Click the button „Status“ in the control software.
The following values apply for the „Level“ display value: Status indicator Bar display control software Meaning 0% 1 to 20% 21 to 36% 37 to 56% 57 to 76% 77 to 100% no reception or not logged in no reception bad reception minimum permissible reception strength good reception good to very good reception 5 red bars 1 red bar 1-2 green bars 3 green bars 4 green bars 5 green bars 13.
14. Response / Error Message a) Response The GSM module can send a response SMS stating the conditions of all inputs and outputs (status display -> also see chapter „Status Button“). For this, an SMS with the „text message text“ saved in the GSM module is sent to the GSM module. The GSM module response is sent to the number that sent the SMS. The message text must contain no more than 8 characters. Also observe capitalisation. • Enter „Reply“ as message text in the control software at „Response / Error“.
15. Installation and Configuration of the Outputs a) „INCALL“ Output The „INCALL“ output switches on for a defined time when the GSM module is called. Because the GSM module does not pick up, this is free of charge! Just call the GSM module and let it ring a few times. Then the „INCALL“ output switches on for the time set in the control software and then off again automatically. This is ideal, e.g., for a garage door opener or front door light. The activation time can be set in 12 stages from 0.
b) SMS Outputs „SMS1“ to „SMS4“ The outputs „SMS1“ to „SMS4“ can be activated or deactivated by sending an SMS to the GSM module. A relay is already connected to the output „SMS1“. A relay (Conrad item no. 502892, not included in the delivery) or a relay PCB (Conrad item no. 585498, not included in the delivery) can be directly connected to the remaining outputs. Every SMS output has its own indicator LED that visually displays the activation process.
A response by SMS is only given to the phone numbers that have sent a correct command and are stored in the control software. Example: Test=1 The relay for SMS output 1 (figure 1, item 9) is switched on after receipt of the SMS. The indicator LED lights up. This condition remains active until the SMS output 1 is deactivated again with a new SMS. For this, send an SMS with the following text: Test=0 The relay for SMS output 1 (figure 1, item 9) is switched off after receipt of the SMS.
Differential measurement: In this case, only the temperature difference is controlled (e.g. forward/backward flow of a heater), meaning there is no TARGET temperature. Once the difference (T2-T1) exceeds the MAX value, the output „TMP1“ activates; if the difference (T2-T1) undercuts the MIN value, the output „TMP2“ activates. „TMP1“ and „TMP2“ are switched off once the temperature difference is again within the MIN and MAX range. „TMP3“ and „TMP4“ are not switched.
d) Alarm Output „ALA“ The alarm output „ALA“ (figure 1, item 11) can be activated from any input, i.e. the output is always switched on when a text message or email was sent. It can therefore be triggered by the temperature control, the optocouplers, the ADC, the logic, the delay and the inverter. A relay (Conrad item no. 502892, not included in the delivery) or a relay PCB (Conrad item no. 585498, not included in the delivery) can be directly connected to the output.
g) Delay Output „DEL“ The output „DEL“ (figure 1, item 14) can switch on and/or off with an input „DEL“ (figure 1, item 5) when the input is switched. Additionally, a text message and an email can be sent when the input signal changes and the switching delay is activated. A relay (Conrad item no. 502892, not included in the delivery) or a relay PCB (Conrad item no. 585498, not included in the delivery) can be directly connected to the output.
h) Logic Output „LOG“ This is the output „LOG“ (figure 1, item 15) that can be logically linked to the two inputs AND, NAND, OR, NOR or EXOR for activation and deactivation. A relay (Conrad item no. 502892, not included in the delivery) or a relay PCB (Conrad item no. 585498, not included in the delivery) can be directly connected to the output. The output has an indicator LED that visually displays the switching process.
16. Installation and Configuration of the Inputs Note: There is a separate 10-minute-lockout for each of the inputs: If a text message has been delivered because of a signal at the input, then this input is blocked for 10 minutes. This is regardless of what happens at this input - it is sent no text message before the end of 10 minutes! Each input has its own 10-minute-lockout. That means, when an alarm occurs on another input, you will receive a text message.
b) ADC Input The ADC input can measure voltages from 0 to 14 V/DC. The voltage to be measured is connected to the middle input (ADC) and the right input (minus). An auxiliary voltage of +4 V/DC is output at the left terminal (+). The GSM module can trigger a message by SMS above and below a voltage set. The threshold value is entered in millivolt (mV). Proceed as follows for configuration: • Open the control software. • Enter a message text in „1 ADC input“. • Determine the threshold value, e.g. 1.0 V (1.
17. SMS Service With this GSM module, you can easily write and send an SMS as on a mobile phone. The SMS is then sent by the GSM module via the inserted SIM card. Therefore, also observe the costs resulting from sending SMS. Once the GSM module has dialled into the GSM network, you can generate an SMS text with the button „SMS Service“ in „Communication“. The SMS may have up to 160 characters. The button „Send SMS“ shows the remaining number of possible characters.
18. Final Assembly Before final assembly, first get familiar with all functions and try out the device in all applications you want to install. To install the GSM aerial, remove the protective foil from the GSM aerial. Glue the aerial to the assembly site you have already tested for good, interference-free reception as described in chapter „Configuration of the SIM-Card“. Place and attach the aerial cable to the place where the GMS module is to be installed (e.g. with cable ties).
19. Troubleshooting a) Possible Errors during Communication Drivers not installed: • Re-install „CP210xVCPInstaller.exe“ on the CD in directory „MCU“ Drivers not installed correctly: • Uninstall and reinstall drivers COM-Port above COM10: • Move COM port: Go to Properties / Connection Settings / More...
d) Possible Errors during „INCALL“ Message „Participant not available“ • Module has not logged on to the GSM network yet: Wait briefly until the module has logged on or move the aerial to another place No phone number displayed in the status • Activate caller ID transmission in the mobile phone Message „No caller authorisation“ • Enter wrong phone number • Caller ID transmission deactivated • Called from another mobile phone or configuration not transmitted e) Possible Errors of TEMP1-4 Signal is not recog
