Trip Computer Multitronics TC 750: reviews. Installation, connection and configuration instructions

Multitronics TC 750 is a color on - board computer, equipped with a TFT display with a resolution of 320x240 and a diagonal of 2.4 inches. If necessary, the user can independently adjust the color design of the display, switching between several color schemes. The powerful 32-bit processor allows the Multitronics TC 750 to work as quickly and accurately as possible. Installation of the onboard computer is carried out on the torpedo and provides direct protection from direct sunlight with the aid of a specialized sun visor.

Why is it needed?

With the help of the Multitronics TC 750, it is possible to support a huge number of different original and universal protocols for car diagnostics. Thanks to this, it can be installed on virtually any machine, regardless of their brand or manufacturer. Even if the vehicle diagnostic protocol is not supported by this device, there is a function to connect to the speed sensor and injector, after which even more functions are opened.

This device has about 200 various diagnostic parameters of the computer, suitable for most of the original protocols, including the service records of the computer, as well as the passport at the level of the diagnostic scanner. The freeze frame information is read in the event of an error in the operation of the entire electronic system, the state of the machine control systems from the standard protocol without the need to switch to the OBD-2 protocol. In this case, not only a thorough diagnosis of errors is carried out, various parameters of ABS, double-glazed windows and many other additional devices are also checked.

What are its advantages?

First of all, its plus is, of course, that it supports the largest number of diagnostic protocols for modern cars. As mentioned above, in the case of connecting to the speed sensors or the injector, a huge number of functions are delayed even if, for some reason, the car does not support a specific diagnostic protocol. A particular advantage that the Multitronics TC 750 onboard computer has is a connection that is simpler than the VC731.

The device performs simultaneous diagnostics of the car with more than 30 additional parameters, and the device itself is equipped with 11 on-board systems that influence the composition of the exhaust of the car. Special attention should be paid to the extremely simple setting, as the configuration can be changed and saved as quickly as possible, using standard PC programs. To connect the device to a PC, you need to use a mini-USB cable.

Settings

Most of the preferences can be edited and saved with a specialized program from a standard personal computer if necessary. Also, if necessary, you can completely transfer recorded travel statistics to a separate personal computer in order to subsequently import into various programs, through which detailed analysis and statistics are maintained for a certain period of time.

Any settings of this computer, if necessary, can be saved to a separate file on the user's computer, which opens the possibility for the exchange of various configuration files between users who are drivers of the same cars. After all the required calibrations are carried out on the same machine, the prepared file can be transferred to other users who are drivers of similar machines.

Connection Features

The Multitronics TC 750 is connected exclusively to the diagnostic socket in the majority of vehicles. It should be noted that this on-board computer provides for simultaneous connection of two parking radars located in the front and rear of the car. It is also possible to simultaneously connect the parking sensors of a specific model, that is, the combination of different devices is impossible.

Additional functions

Among the additional functions, special attention should be paid to the voice accompaniment of the modes and all parameters, that is, their numerical values can be pronounced. It also deserves attention 21 voice warning about all sorts of accidents or outages beyond the facilities.

In the event that the electronic system of the car fails, the on-board computer not only warns the driver that the problem has occurred, but also provides detailed information regarding the error code and how it is decrypted. Thus, the driver will immediately have information about whether you need to eliminate the cause of the problem immediately or continue driving, and only then to deal with this issue.

Hot Menu

This function allows you to get the fastest access to various applications that are in the "Settings display". The user has the ability to customize this composition at his own discretion, while pressing a single button to call a full list of available settings and functions, located in different places in this menu. In addition, there are also four completely independent menus for the Parking, Taximeter, Medium and Parameters applications.

It should be noted that the Multitronics TC 750 on-board computer provides information only on two parameter charts, but you can use the specialized function "Countdown", which allows you to switch over graphs and determine if necessary the numerical values of parameters in the past tense, or compare them with each other .

Extremely high accuracy is present in the process of monitoring fuel consumption or such parameter as the duration of injection. In the event that there is a serious change in these characteristics, the driver is immediately given a warning, as well as the numerical value of the change in fuel quality.

What else can this computer do?

On-board computer Multitronics TC 750 always warns the driver if he tries to start a trip without the passing beam on, and also makes a warning if the dimensions were not turned off after the end of the trip. It is envisaged that the computer can be used together with special gas equipment, thus ensuring an extremely accurate calculation of fuel consumption, taking into account a separate gas correction.

Setting up the Multitronics TC 750 allows you to use it as an oscilloscope in the event that a dedicated optional cable is connected to it. This ensures detailed observation and analysis of signals received from various circuits and sensors directly on the display, while all information can be stored and transferred to the user's personal computer.

If you can compare the recorded signal with the reference one, you will have an additional opportunity to conduct diagnostics of all the car components in the event that there are any difficult to diagnose problems, such as shorting, wear, jamming and many others. In its capabilities, such an oscilloscope is extremely similar to a standard desktop solution, since it is possible to control the trigger, sweep and change the time intervals.

Reviews

About Multitronics TC 750 reviews give positive feedback. Many people say that the device has a lot of function, and also works stably for a long time, which is a problem for most other similar devices.

In particular, the Multitronics TC 750 user reviews are as follows. They note that this is a worthwhile thing. Shows all necessary and even not the most important information, while it determines and recites various errors, which allows you to immediately reset them. Works without any problems. Connection to X-Trail takes 20 minutes.

How is the installation carried out?

In Multitronics TC 750, the dimensions allow you to install this computer in almost any car, which is perfectly combined with its multifunctionality and other features. At the same time, it should be noted that the installation of this device is also quite simple, and almost every car enthusiast will be able to cope with it, who are familiar with the peculiarities of their car and understands electronics a little.

Instructions

1. The main module of the Multitronics TC 750 computer is assembled. The instruction says that you first need to insert the module into the insert, after which you already have to install the clamping frame and screw the structure with three screws.
2. A loop is carried into the window located on the computer case.
3. The loop is connected to the Multitronics TC 750 and the body is closed.
4. Carefully degrease the place of gluing, after which the on-board computer is glued to the installation site using a double-sided tape, supplied with the device.
5. The interface cable and parktronics (if there is one available) are laid under the lining, after which the computer is connected in accordance with the electrical scheme.

How to connect the parking radar?

If necessary, you can also connect the parking radar to the Multitronics TC 750. On which machines the on-board computer was installed, in this case it has absolutely no value. The connection procedure itself is carried out to the two end contacts of the additional connector. It should be noted that in this case, the marked side of the connector should go to the main connector of the on-board computer.

At the same time, if the PT-4TC model is installed, the installation procedure is somewhat disconnected. This device is connected to the contacts of the additional connector (from the second to the fourth one), with the marked side of the connector must necessarily be facing the edge of the on-board computer.

In the event that the simultaneous connection of two parktronics located behind and in front is made, then the connection of the loops is carried out in parallel. Provision is made for the simultaneous connection of party members only to a particular model.

Select Protocol

Initially it will be necessary to sustain a few seconds of pause after the Multitronics TC 750 is connected to the diagnostic socket . The device can be installed on various cars, but if after the installation it is not turned on and started the engine, the device will enter standby mode, and after a certain time Completely disable any lighting.

When the engine starts, the on-board computer starts to automatically detect the protocol, but if this does not happen, then it will have to be done manually through the "Setup display". To do this, the ignition again turns off, and again pauses before the display turns off in the computer. This is done as follows:

• "Sources";
• "Specific flow channel";
• "Hand.";
• "Duct.";
• The protocol you need is selected, then the "SET" button is pressed.

It should be noted that in some protocols, it is also possible to configure additional parameters that will affect the operation of the computer during the diagnostics process. This feature is often noted about Multitronics TC 750 user reviews.

Checking

It is highly recommended to check the correctness after selecting the protocol. To do this, the engine is started, after which the menu "Display parameters" is selected and the "SET" button selects the display with the specified parameter. To verify the validity of the test, it is necessary to pay attention to such characteristics as engine speed and temperature.

In the event that these parameters are displayed incorrectly, you should repeat the above points in full, and in particular select a new type and subtype of the protocol, or change the type of errors and other parameters if they are present in the variant you have chosen. Only after these procedures it will be possible to completely change the protocol to a new one.

Be sure to check whether such a characteristic, such as "Instant fuel consumption", changes during the engine speed change. Before the calibration is carried out, you can not rely on the numerical values of the instantaneous flow rate and speed that you received, since they must be customized for each car individually.

If you selected all protocols, but none of them shows the correct parameters of your car, it means that the diagnostic protocol for your car is not supported, so you can work with the device only in the universal mode.

Display of the remaining fuel

If necessary, the multitronics tc 750 on-board computer, which you can read about above, displays the rest of the fuel in three different ways.

In the "Settlement" mode, there is no need to directly connect to the fuel level sensor, that is, the user constantly adjusts the fuel reading in the tank, and then the computer will carry out the calculation of the remainder by driving the fuel by subtracting the consumed fuel. This mode differs extremely high accuracy, since there is no dependence on the serviceability of the fuel sensor, the voltage of the on-board network or the position of the vehicle.

The DUT mode requires the device to be connected to the fuel sensor of your vehicle, but the ECU ECU mode no longer requires this connection. The voltage of the DUT in this case is read directly from the diagnostic line. It is worth noting the fact that in these modes the user does not have to manually enter the amount of fuel after each refueling, since the readings will be directly read from the fuel level sensor. Thus, the use of the "Calculated" mode is only relevant if, for some reason, the other two modes do not provide normal results while the on-board computer is running.

In addition, in order for the Multitronics TC 750 trip computer to work properly and properly calculate the fuel consumption of the car in case of installation of gas equipment, it will be necessary to connect the device correctly, and then activate the special mode "Gas / Gasoline". In addition, you should manually reset the average parameters in each of the sections "Displays-Medium".
