QUICK GUIDE

If you are in a hurry to test your module and already has some experience with electronics, with the few connections showed in the diagram below you can test it. This example will use a low cost cellular phone Nokia 1616 or similar. As result you will hear a relay opening and closing. But remember, read the manual later, because you will find important information about its complete installation and operation.

1) Taking advantage of the headphone cord and plug normally provided with the cellular phone, cut the

cord and connect the green wire (speaker) to the CN2 pin 1 (audio), the white wire (showed here as yellow) to the CN2 pin 3 (MIC), and the green/red wire plus the shield to the CN2 pin 2 (ground). These connections may vary depending on the phone model or manufacturer.

2) Insert the plug in the cellular phone jack and enable the auto-answer function1;

3) Provide 12V DC Power to the CN1 connector. Positive at pin 1 and ground at pin 2;

4) Call the number of the cellular phone and wait for the answer. If everything was done right, you should hear beeps, meaning the module is waiting for commands. If not, review your connections.

5) Software versions A or B: Dial 21 to turn the relay 2 on, 20 to turn the relay 2 off, 22 to pulse relay 2, 23 to check relay 2 status. Software versions C or D: 61 to turn the relay 2 on, 60 to turn relay 2 off, 62 to pulse relay 2 and 63 check relay 2 status. Two quick beeps means turned on, a long beep means turned off and one quick beep means pulsed.

1 To configure the auto-answer feature go to the SETTINGS menu/Accessories/HEADSET and enable auto-answer. This specific menu is shown only if the headset is connected to the phone jack. An icon is shown on the display symbolizing that the headset is present. If the icon does not appear, review the connection of the connector CN2.

PRODUCT DESCRIPTION

The MCR500 is an innovative and extremely flexible product for remote control electrical and electronic equipment. It has a high sensitive DTMF tone decoder and is able to identify tones even in noisy environments. Through these tones, whether from cellular phone or any other audio source, you can control up to five outputs, three of which have build in relays and two which can use external relays. When we connect the audio output and microphone of a cellular phone in MCR500, we have an unprecedented automation system. We can call from anywhere in the world and control any type of fixture. It can be used as a car block device, as remote reset of servers in data centers, as Access Points reset system, as electrical switch for turn on or off devices at home, office or industry. Applications only rely on your imagination. 5 software versions available

Version A - Suitable for use as a car blocking system. With a simple phone call, you can block the vehicle in case of theft, or turn on or off a siren and two outputs accessories. The module also has two

signal inputs ports, one of which can be connected to the car alarm, which if triggered causes the module to send a dial pulse on the output 4 (relay 3). This pulse can cause the cellular phone to place a call to a number in its memory alerting the owner. A second input can be used as a manual block switch, acting as an efficient anti-theft. This version includes blocking specific functions such fuel fault simulator and an automatic blocking and if power is disconnected and reconnected. The siren will sound too. Version B – Its operation is similar to version A, with the sole difference is that the output 4 is used for another purpose. Typically, you use a car charger to keep your cellular phone always charged, and when your battery is fully charged, it stops supplying power, increasing battery life. But there are those who prefer to use the cellular phone without the battery, powered by a 4.3V output voltage provided by the module. In this case, if for some reason the car battery is disconnected, the phone does not come back on. To circumvent this problem, output 4 (Accessory 2) emits a 2s pulse used to drive the power button the phone to turn it back on. This function requires soldering inside the cellular phone to reach the power on button contacts. Depending on the cellular circuits, may require a relay.

Version C – Recommended for general use, where all outputs can be turned on, off, pulsed and have its status checked. All outputs have memories of the last state in case of power failure. As this version uses different commands, it can be used in parallel with one of the previous versions in order to double the outputs ports.

Version D – This version is also for general use, allows you to turn on, off, pulse and check status from outputs 1, 2 and 3. The outputs 4 and 5 are directly pulsed. For example, to pulse output 4, just press key 7, it will remain on as long you keep the key pressed. When you release the key, the output Will turns off.

Version E – This is a customizable version. The customer chooses the behavior that he wants for each of the five outputs and two inputs. Some customers have specific needs for use in equipment or industrial automation projects. We make exclusive firmware software for these cases. The price for this version is negotiated according to the complexity and volume of the request.

INSTALATION

MCR500 module is designed to operate in conjunction with a cellular telephone or any other source of DTMF audio, such as radio transceivers, etc. In the case of the cellular phone, use the cord of the headset that normally comes with the cellular phone. If you not have the headset cord and plug, look for cellular accessories stores and get one compatible with your device. Cut the cord with the minimum length required for its installation, shorter cables have less chance of noise and interferences caused by GSM cellular. The signals needed to operate the module are: Audio output from the cellular phone (The module will decode the DTMF commands received by you phone), Cellular microphone input (to send confirmation beeps) and ground (GND). There are not standards between cell phone manufacturers, so each model may have different combinations of connections. But it is easy to identify which one are the headset speaker and the microphone by following the connections before taking the headset apart. As the audio inputs are isolated, there is no danger in damaging the cellular phone or module in an attempt to connect the cable in case of reversed connection. In this case, if the module does not decode tones (DTMF LED does not blink), or the confirmation beeps are not heard, try another combination of connection.

1) Connect the audio1 (speaker signal from cellular) to the CN2 audio input pin 1;

2) Connect the ground signal (cable shield from cellular) to the CN2 ground input pin 2; 3) Connect the microphone input (from cellular) to the CN2 MIC output pin 3; 4) Connect a 12V DC positive to the CN1 12V input pin 1 and the negative to the CN1 pin 2; 5) Enable the auto-answer function in your cellular phone. Call from another phone and wait the answer.

If you hear a beep every 4s, means your module is waiting for commands. If you not hear, please, review your connections at CN2;

6) Dial 22 and check which the yellow led blinks according your dialing. If everything is connected right, you should hear a relay sound. This mean your module received the commands and successfully executed.

Cellular Power for versions A and B With a generic cell phone car charger – It’s recommended to use an automotive charger; it is very

inexpensive and can be found in any cellular accessories store. It always keeps the battery charged, and prevents overcharging the battery because it turns off when it is fully charged. Using the 4.3V VCEL Output - If you prefer to use the module output VCEL 4.3V to power the phone without battery, it is recommended to install a good heat sink on the voltage regulator U1. Verify that your cellular phone can operate with 4.3V and it drive less than 600mA. It may damage the module if drives more. In the case of the vehicle battery is disconnected and reconnected, the cellular will remains off. In this case, it is recommended to use the B version and use the power on pulse to turn the cellular on when powering up. This configuration requires internal connections directly to key contacts inside the cellular phone. For details on these connections, see pages 10 and 11.

1 Usually the wires used in these headset cords have an insulation coating. To be able to solder these wires

you should heat for more than 10s with the tip of the soldering iron until this coating melt. 2 The module MCR500 has no audio level adjustments. Although its circuit has an automatic gain control that

will amplify weak signals and reduce excessive signals, is recommended to try several volume levels in your cellular phone to find the best operating range. Volume too low or too high can result in fault commands. The module has a yellow LED (DTMF) which should blink according to the DTMF tones dialed. It should light up, always a number is entered. If there are fluctuations or if it does not light up with some numbers, try adjusting the volume of the cellular phone. Test and make sure all the dialed digits are recognized with the audio adjustment made. Depending on the audio quality of the connection, keys 1 and 2 may not be decoded properly. In this case, replacing number 1 by * and the # 2 can solve the problem. This LED may blink slightly when power the module up, but will remain off and should only blink when receiving commands. This led will stay off when not receiving commands and this is normal. If the audio signal is poor or there is excessive noise in your call, commands may not be recognized correctly. In this case, hang up and call again.

OPERATION – VERSION A AND B

Pump cut off (pin 15 and 16) – These pins are to be connected to the electrical circuit of the fuel pump. In case of theft, simply call the cellular phone and send the block command. This output will simulate the fuel running empty for 30 seconds and will cut the pump completely forcing the vehicle to stop. This simulation is an extra security because it gives the driver a chance to get out of a possible dangerous situation. The command 11 blocks and the 10 unblock. For safety, if the module power is turned off and on, the pump will be turned off and the siren will fire. In this situation, the module will also make a dial to alert the incident. To disable this block, call the module and send the unblock command (10). 70 unblock and turn siren off at once. Siren (pins 6 and 7) - Although this output can be used with other types of accessories, it is recommended it to be connected to a siren. This must be installed in a place hidden and apart from the vehicle alarm siren (if any). You can control this siren through commands whenever necessary. In case of violation, the siren will sound. The output pins are normally opened (NO) contact and common (C). When enabled, the circuit is closed. To sound the siren, enter 21, to silence it, enter 20. For a single pulse dial 22 and 23 to check status.

Accessories 1 and 2 (pins 12 and 13) - Use these outputs to control accessories. With them you can turn on, off, pulse or check status. These outputs are open collector type. When enabled, are grounded. When turned off, are in high impedance. To trigger an external relay, simply connect it to one side of the relay coil. The other side of the coil is connected to 12V. Never connect 12V directly on these outputs, the module will damage. For accessory 1, command 31 will to turn it on, 30 turn it off, 32 pulse and 33 check status. For accessory 2 send commands 41 to turn it on, 40 to turn it off, send 42 to pulse and to check status. If using version B, the second accessory output (pin 13) is not available for controlling accessories, but it will pulse for 2s to power a cellular on in case the module it was powered off. Dialer1 (pins 3 and 4) - This output can be connected to one of the speed dial keys of the cell phone in order to make a call alert in case of violation of the vehicle. This output also tries another call 20 seconds after the module is connected to 12V. This feature requires soldering inside the cellular phone key contacts. Block Switch3 (pin 11) - This input can be connected to a switch to the vehicle's 12V. With the switch closed (12V), output 1 (block) will be activated. With this switch opened, it will be deactivated. This switch may be

useful in a daily basis use, because it avoids the need for unnecessary calls. Violation (pin 10) - If this input receives a positive signal (2V ~ 15V) for more than 4 seconds, the block and siren will be activated immediately and the output will pulse 2s for call alert. Connect this input to the siren alarm of the vehicle or in any other place that provides a signal that the vehicle was tampered with. The delay of 4s to trigger ensures that the sound emitted by the siren of the alarm when turned on or off is not perceived as a violation. Once this input has detected a violation, the vehicle will be blocked until the unlocking is done by phone. 1 This feature requires soldering contacts directly into the phone's keypad and requires a degree of expertise. Some cellular phone models have a redial button on the handset cord, in this case, there is no need to open the phone, use the contacts of that button. 2 Phones usually have speed dial buttons which if pressed for several seconds will make a call to a stored number. For more details about this feature check your cellular phone manual. Always program your phone to the vehicle collect calls. This prevents which the cellular runs out of credits (if prepaid) and can still make call

alerts. 3 The block command has priority over the block switch, so if the vehicle was blocked by command, it can only be unblocked by another command. This allows, in the event of an armed robbery, the driver of the vehicle to reveal the location of the switch (if he or she is forced to do so). Once he or she is released, he or she can block the vehicle with a phone call, and this block cannot be disabled by the switch by the thief.

Emergency Switch (Bypass) It is recommended to install a hidden switch connected in parallel with the relay contacts of the block output.

In the event of a problem of access by phone or system malfunction, this switch will allow the fuel pump to work in order to use the vehicle. Protection of the module shutdown According to experts of the security sector, is an increasingly common practice to shut down the vehicle's battery so the thief can seek out and disable the alarm siren. For this reason, we suggest that the module use a dedicated siren installed in locations less targeted and always separated from the vehicle alarm module. As extra protection, as the module is connected to power, the output will block and the sirens will activated, causing the vehicle to stay blocked when the battery is reconnected. Furthermore, after 20s, the dialer will call the stored phone on speed dial, sending an alert. This initial block can only be disabled by commands over the phone. 1 The output 5 is not available for commands; Its directly controlled by the microcontroller, as it is used as output the dial in the event of violation.
