Note that if you need a scan tool then you can build your own quite cheaply,and use our own free software (see last paragraph below).
For this we go to the section 'Downloads DIACOM' and download the software we need together with a brief description for further introduction. In addition, for a more detailed studying of the programmes, company plans in the near future during the short period of time (the process of work has already begun ) to prepare and submit video courses.
DIACOM stands for Diagnostic Interface for Automotive Computers.
Diacom displays diagnostic information, available from a vehicle's ECU, on a PC screen.This process is shown in the diagram and highlights that the Diacom hardware connects to both thevehicles ALDL connector and the PC's parallel port. The Diacom software is controlled from the keyboardand displays results on the PC's screen. Not shown is Diacom software's ability to saveand load information to and from disk.
Rinda's information on Diacom lets you downloada demo. But, as you'll see, it's really an advertisement, but does show Diacom's user interface.Diacom's strength lies not in its relatively unsophisticated software and its very simple hardware,but in the database of vehicles that Rinda maintains and that Diacom therefore supports.
For many early ECUs, Diacom can only tell you very basic information about your vehicle,because that's all that's available from the ECM.For example, the Australian Holden VN Commodore uses a GM P4 series ECU(type number 1227808)and this ECU outputs just twenty (20) bytes of data. But that 20 bytes can be used to diagnosequite a number of faults present in the ECU itself, within a vehicle sensor, or with the vehicle's wiring.For an experienced mechanic using a 'swap and retest' methodology, this can be enough extra informationto enable accurate and speedy fault identification.
The problem, for the average weekend handyman, is that Diacom is not a cheap product to purchase.
The three transistors in the middle and to the right control the ALDL mode selected.The two transistors on the bottom right read 160 baud ALDL and other data.The transistor at the top and the middle leftmost are for reading (and writing) 8192 baud data streams.The bottom leftmost transistor enables the other transistors above it.
I have made up this circuit and can verify that it works ona Holden VN Commodore with software supplied by Rinda.Rather than use 2670 ohm resistors, I used 2.7k (also called 2k7) ohm resistors,and I also used BC547 transistors rather than the ones suggested(these are garden variety NPN transistors).
This is a picture of my one-off unit. The wires on the bottom go off to whatever ALDLconnector you require for your vehicle (ie. the Car ALDL connector in the schematic).
The photo also shows a red LED, on the left, to indicate power(connect to pin H for some vehicles)and a green LED for ALDL data (connect to pin D or E depending on vehicle).These were added as a diagnostic aid and connect to the points above and GND,with a series 3k3 current limiting resistor.

What is hidden under the devices manufactured by 'DIACOM'? In this section we will try to acquaint the guest of our site with the product line 'DIACOM' and as close as possible to the field of instrumentation for alternative and classical medicine, which, of course, include the development of our company.
The main distinctive feature and the main advantage of the company is the correct organization of work based on cooperation and exchange of long-term experience of many experts from various areas and the countries of the world that allows to create and develop products unique on the quality and functionality, using the latest achievements in the field of science and technology. We are talking about the so-called symbiosis and combining the efforts of each specialist and employee of our company in order to achieve the best result. Feedback from DIACOM with its customers is also important, and we always listen to their opinion, which undoubtedly affects the quality of the equipment produced and the programs developed.
Due to the constant development of technology and our company does not stand still. Our product line is being improved, expanded and updated to meet the needs of our customers and end users.
In the list of priorities of the company the first place, undoubtedly, is taken by quality of the made production that today radically distinguishes our devices from the similar devices made by competitors. Popularity and demand of our devices is confirmed by numerous attempts of fakes, however the DIACOM company doesn't remain indifferent and in this sphere, making the mass of efforts in order to avoid penetration into the market of low-quality production.
We try to monitor the market situation and inform You in a timely manner about the products found by us, supplemented by a photo and a brief description. From time to time our company carries out special actions aimed at helping customers who have purchased substandard counterfeit products. Help is to exchange the device for the original on more favorable terms. Next 'DIACOM' campaigns to replace used appliances of the modern. Such steps once again show that it is extremely important for the company to build relationships with its customers based on trust, support and mutual assistance.
We care about our customers and want to give them the best that we are able to produce.
Many years of experience, innovation, continuous improvement – all this is an integral part of our products.
DIACOM software is another important component of our products. The best programmers, engineers, doctors, lawyers, designers and many other specialists are involved in the development of programs for DIACOM devices. It is worth noting that the presence of many years of experience is not the main factor of our employees. This undoubtedly plays an important role. We cooperate in parallel with young professionals who have a new, fresh, multi-faceted, sometimes completely unique view on the subject, which ultimately allows you to create a completely unique in its qualities and characteristics of the final product – Diacom Software. But before the light is born the final version of the program – there is a process of long and hard work, which is manifested in a series of disputes and discussions, the so-called 'brainstorming', numerous consultations and dialogues, UPS and downs. Continuous improvement and compliance with the requirements of its fields of application – another confirmation that the company 'DIACOM TECHNOLOGY' is keeping pace with the times, sometimes even ahead of it.
What is the manifestation of our uniqueness? We draw your attention to the path that we chose when creating software. It will be a question of our inherent desire not to limit our users to a minimum set of software, writing it to a carrier, but to provide a non-standard more flexible alternative method, where the popular Internet has become our assistant. In our time, perhaps, there is not a single settlement, limited access to the Internet. The global system of integrated computer networks for storing and transmitting information, or in other words, the global network has entered almost every home and today there is almost every street. An indicator of 2.4 billion users who regularly use the Internet, which is more than a third of the population of our planet, is proof of this. What attracts the Internet and why did we choose it? The answer is simple - a means of prompt transmission of data and information, respectively, allows you to quickly deliver to you our latest developments, which, of course, at the modern pace of life, every person will appreciate. At the same time, we leave the possibility of sending a software CD at the request of our client, but this does not guarantee that you will receive the best and most modern thing we produce.
Where can you download everything you need? To do this, we select the desired section of the software and download it by clicking on the appropriate link to download. On the software page You can find a brief description of the functionality and purpose of the software.
In addition, for a more detailed study of the programs in the company's plans in the near future and as soon as possible (work has already begun) to prepare and send You a video course on working with any of the selected programs. We have also initiated the process of opening 'Authorized service and training centers DIACOM', the main purpose of which will be qualified training for further work on our software products and devices. Now our official representatives with support of the manufacturing company are engaged in it.
We sincerely hope that our actions will help in the improvement of products, as well as contribute to the correct and comfortable work on the devices and software. To do this, we make every effort to achieve our goals.
Be a part of our team! After all, it is much easier to overcome difficulties together! Without any doubt - it will bear fruit!
