Multitronics TC 740 is an on-board computer installed on passenger cars of foreign and domestic production. The trip computer of this model is best suited for off-road cars of the Lada family, for which it is highly valued by car owners. Additional advantages include a universal mount and an affordable price.
The versatility of the Multitronics TC 740 trip computer lies in its compatibility with most cars and the ability to mount it in a non-standard place - for example, on the dashboard of a car.
Computer overview
The design and materials of the TC 740 are made at the highest level and meet the latest requirements of both Russian and foreign automakers. Car owners also rate the Multitronics TC 740 on-board computer highly in reviews.
Display
The on-board computer is equipped with a 2.4-inch TFT graphic screen with a resolution of 320x240 pixels. The temperature range of the display has been increased andvaries from +50 to -30 degrees, which almost completely corresponds to the temperature range at which cars are operated.
An additional advantage of the Multitronics 740 display is the ability to display information in various ways, including animation. Such properties increase the attractiveness of the model for car owners who are demanding on the appearance of the device.
Connecting a computer to a car
On-board computer "Multitronics TS 740" is connected to the car in several ways:
- Connecting to an OBD-II diagnostic socket is the easiest option. It is carried out in 30 minutes, and most of the time is spent on laying the cable inside the dashboard. The car owner then remains to configure the computer according to the algorithm specified in the instruction manual included in the delivery.
- Connection in universal mode. Trip computer Multitronics TC 740 connects directly to the vehicle's injector, speed and fuel level sensors. This method is resorted to when the technique does not determine the type of controller and the protocol for its operation. Thanks to this, you can use all the functions of the computer with the exception of the diagnostic scanner. In other words, in Multitronics TC 740 universal mode, it is not able to read and reset ECU errors.
- Combined connection method. The equipment connects to the car in the first way, but information about some data is not transferred toECM, which is why you have to resort to the second method.
Computer Advantages
The Multitronics TC 740 on-board computer stands out among analogues with a mini-USB connector, quality control functions and an "econometer", with which it is possible to plan and control a trip based on fuel consumption.
An additional advantage is the connection of parking sensors: two parking sensors can be synchronized simultaneously with the on-board computer using the optional ShP-8 cable.
Functional and diagnostic options
The wide functionality of the computer includes the following features:
- Multitronics TC 740 is equipped with a TFT display with a diagonal of 2.4 inches and a resolution of 320x240 pixels. The operating temperature range of the computer varies from -20 to +45 degrees. The color design of the screen is configured by RGB channels. The user can choose from four color schemes with quick switching.
- High speed and performance of the on-board computer is achieved through a 32-bit processor. The updated software interface, combined with a powerful processor, provides a wide range of functions.
- Availability of informative multi-displays - pointer, adjustable and graphic. The manufacturer offers up to 35 displays for one parameter, three displays for 9 parameters, 4 displays for 7 parameters and 6 displays for 4 parameters. Pointer and graphic displays are offered in two settings maximum. For parking sensorsconnected to the on-board computer, displays are also provided.
- Multitronics TC 740 supports both generic and original diagnostic protocols for most modern vehicles. The computer can also connect to the vehicle's speed sensor and injectors.
- Extensive diagnostic capabilities allow the on-board computer to control the operation of more than 30 additional parameters and read information from freeze frames for 40 different parameters.
- Simultaneously with the trip computer, two parking radars located on the front and rear bumpers of the car can work at once. Manufacturers recommend installing parking sensors of the same brand.
API Features
The upgraded software interface of the Multitronics TC 740 on-board computer offers the car owner a wide range of options and instant access to most of the model's functions:
- "Hot" menus provide quick access to the most requested parameters. Each menu contains up to 10 different functions at the discretion of the user. All four independent "hot" menus are called up by pressing one key.
- The Journey and Fuel Log feature collects vehicle usage statistics. The virtual document is stored in the memory of the on-board computer and contains information about the latest routes and refueling of the car. It is possible to configure the trip computer to fix inautomatic mode of the last 20 trips and refuelings.
- The device controls the quality of the fuel poured into the tank using the "Fuel quality control" option. The memory stores reference values for the duration of injection and the operation of the power unit, on which the system relies for subsequent comparisons. The on-board computer, when the data deviates up or down, informs the user about this.
- The "Countdown" function displays several graphs of instantaneous parameters on the on-board computer at the same time, comparing them with each other.
- The Multitronics trip computer also notifies the driver to turn on or off the parking lights and low/high beams.
Synchronization with PC
Connecting to a personal computer allows not only setting up the car's on-board computer, but also editing and saving files and configurations. The device comes with a miniUSB cable that allows you to connect it to a computer. The generated settings file can be used later to calibrate similar computers.
The software is updated via the Internet. Thanks to the synchronization of the on-board computer with a personal computer, it is possible to conduct a detailed analysis of the collected static and operational data for a specific time period.
Additional devices
The Multitronics on-board computer can synchronize simultaneously with two parking sensors of the same brand installed on the front and rear bumpers. The front bumper is triggered when an object approaches the car at a distance less than the allowed one, which will be notified by the on-board computer. Operation indication can be audible and visual with the display of the distance to the object.
The rear parking sensors are activated after the reverse gear is engaged, which is accompanied by a sound indication and display of information on the on-board computer display. The data allows you to determine how far the object is from the car.
