Onboard computer Multitronics UX-7: manual, reviews

On-board computers for cars half a century ago could be considered fiction. Then this technique was just beginning to be mastered by the aviation and space industries. Today, the circumstances have changed beyond recognition, and most modern cars are already equipped with such a simple, but necessary device from the factory. But what to do to the owners of domestic machines that were supplied without this necessary device? The Multitronics UX-7 model comes to the rescue, which gained popularity due to its low price, simplicity in installation and compact size. Let's get a little acquainted with the strengths and weaknesses of this device.

What is an on-board computer for the user?

It is worth noting that this model has received a very minimalist design, so it does not take up much space on the panel and can be placed almost anywhere. This simplicity was achieved by choosing to display a three-character seven-segment display. It is enough to display all the information necessary for the driver. However, it is very compact.

The main unit Multitronics UX-7, which collects information and decodes error codes, is hidden under the hood and is not visible to the user at all. Therefore, apparently not everyone can understand what exactly this machine has undergone to completion.

Easy installation

This model was able to conquer many novice motorists. The reason was the extreme ease of installation. The fact is that in this on-board computer there are no connectors for connecting additional sensors. All information is obtained directly from the diagnostic bus of the car, which even a beginner can easily connect to. After connecting, it is necessary to secure the central unit securely, and set the display to the free space for the switch.

You should not have any problems with the configuration of the Multitronics UX-7. The user's manual contains all the nuances regarding setup and calibration. If your choice requires cost savings, then with this model you will get it doubly - the first time to buy the bortcomputer itself, due to its low cost, and the second - at installation, as you can produce it yourself without outside help.

How is the driver notified of a malfunction

Despite some convenience, a small display imposes certain restrictions. For example, the output of error codes will be represented in the form of three-digit numbers. In order to determine which device or node signals an error, you will have to look at the table. This manipulation, of course, will have to be done only if you do not already know this table by heart. Over time, the most common errors Multitronics UX-7 are remembered, and the need for the table disappears.

In addition to the visual display of information, there is a sound signal, which allows you to notice the deviations in the car's operation in time. In standby mode, the display may show other information necessary during the course of travel. This can be the current charge of the battery, the rest of the fuel in the gas tank and even speed control. Let's analyze this feature a little more detailed.

Speed mode notifications

Since the Multitronics UX-7 on-board computer can receive information on the current speed directly from the computer, the manufacturer decided to use this feature for the benefit of the driver. The point is to set up a certain speed indicator, at the intersection of which a short beep will be issued. How can this look in practice?

Suppose you set up a sound signal at the intersection of a mark of 60 kilometers per hour. In this case, if you go around the city and hear the buzzer sound, you will know that you started to exceed the speed, even without looking at the panel. The repeated signal will notify you of the speed reduction to the required level.

On the road, on the contrary, you can hear when the traffic speed becomes too low and can interfere with other participants who travel with you on the same lane. Proper use of this function will significantly reduce the likelihood of a penalty for exceeding and will allow less distraction on the speedometer while driving.

Firmware Upgrade

The manufacturer has provided the possibility of updating the software of the device. Together with the updates, new functions can appear that will expand the capabilities of the Multitronics UX-7 on-board computer. To perform the update, you should stock up with a special regular cable that will allow you to connect your device to the computer via USB. Following a simple instruction, you can perform all the necessary operations.

Specifications of the device from the manufacturer

As for any other technology, the manufacturer provides a list of basic specifications, relying on which, and you should connect and configure the device.

Among them, the most significant are:

• Power for the device is permissible in the voltage range from 9 to 16 volts.
• Consumption of the gadget at work will be no more than 0.15 ampere.
• In standby mode, the device consumes about 0.018 amps.
• It is quite comfortable on-board computer works at temperatures from -20 to +45 degrees. However, reviews show that this range can be higher.
• You can transport the device at a temperature not lower than -40 degrees and not higher than +60.
• The choice is available orange or green color seven-segment indicator, which displays information on-board computer Multitronics UX-7. The instruction how to adjust the output of a certain parameter is in the attached documentation.

Having become acquainted with the basic characteristics, it is already possible to draw a definite conclusion. But what do they say about this on-board computer reviews?

Positive moments noticed by users

The main advantage of this on-board computer is the low cost. Even for this, it would be possible to forgive him for a few small problems, but there are not so many of them. We'll take a closer look at the details later. So, for a relatively small price, the user receives a device that allows you to measure, depending on the brand of the car, up to 66 different indicators. This is satisfied by most regulars of car forums, and they note that such a figure is quite acceptable and allows you to make the necessary diagnosis of the vehicle on the road, as well as monitor its condition.

The second important positive aspect is the possibility of resetting one or another error. After signaling a fault, you can reset the data to the computer and block further signals. This is necessary in order to get to the nearest service center, taking into account the appeared malfunction. If you do not turn off the fault notification, the vehicle's ECU may block the possibility of further movement, and this can lead to unforeseen consequences. But if you are confident in your abilities, then you can completely bypass such a lock using an on-board computer. About similar situations, users of Multitronics UX-7 reviews write on the forums, telling how this feature helped to save on the evacuator.

The third plus has already been discussed - it's easy to install. No hikes for services and spending extra money - all the work is done by yourself. In the case of the Multitronics UX-7, the installation becomes more fun than real work.

Well, the fourth positive point can be called the fact that, according to users, even on frosty winter days, when the temperature drops below -20 degrees, the device continues to function in its normal mode. As far as it hurts him, it is not known, but cases of failure due to too low operating temperatures have so far not been fixed. This once again confirms the reliability of the model.

The disadvantages of this on-board computer

Perhaps, ambiguous reviews cause the display, through which the events are displayed. If some users are satisfied with its minimalistic design, then others face the problem when a certain code displayed on the display is literally behind the wheel looking for a table.

Another disadvantage is the poor compatibility with cars that are not listed in the manufacturer's recommended list. And the list is rather short, and it includes only a few brands of domestic production. Of course, if the data transfer protocol coincides, the Multitronics UX-7 computer will work on any car, but its functionality can be significantly reduced.

conclusions

This model of the on-board computer for the car is most suitable for owners of domestic cars of recent generations. It is intended for those who like to save money, because it is inexpensive and easy to install.

The user needs a good memory for the numbers to remember what this or that error code means. If the device is properly configured, it will display the necessary parameters in real time and even give sound prompts. The Multitronics UX-7 model will be an excellent solution for novice motorists, but you should not define it as your ultimate goal. Do not forget that whenever you can, you can always change it to a more informative on-board computer, for example, using an Android device as a display.
