The secret is that every manufacturer automotive gas equipment seeks to make a profit by selling additional equipment - special controller programming cable. If you are installing HBO, you probably noticed that the vast majority of installed equipment has two types of diagnostic connectors:
1) AGIS, ALTIS, STAG 150, OMVL – some other types HBO.
2) Zenit, Stag-300, Stag-4, and others (in the photo the connector coming out of the control unit) ( The pinout is shown for the Zenit system, in Stag +12 and Gnd are swapped).
The photo shows 4 wires going into the connector. Two of these wires are (+) and (-), and two wires carry the Rx and Tx signal. The whole difference is in the location of these wires in the diagnostic block, i.e. Each manufacturer, in order to sell a cable of its own making, places the contacts in the diagnostic block differently (for example, when connecting a cable for Stag-300 to Zenith, the cable is damaged because the positive and negative wires in the block are mixed up).
To solve the problem, it is enough to make a universal connector. For example this:
To save yourself the hassle of repairing cable If the connection is incorrect, before connecting using a multimeter, you must check the diagnostic connector pins on the equipment (some systems supply power to the diagnostic connector only when the ignition is on).
Having correctly connected (+) and (-), then we connect the signal wires.
Sometimes there are cases when the diagnostic block has simply rotted or there is no longer a plus or minus on it. In this case, the power wires CABLES They are connected to the battery, and only signal ones are connected to the diagnostic block.
Warning
You should always carefully check the polarity of the power connection to the cable.
Where to get the Lovato-Stag cable terminal from
During production cord for HBO diagnostics, the question arises - “Where can I get the connector?” For HBO cable Lovato-Stag You can use the connector from the fuel pump of domestic cars - GAZ, VAZ. The full name of this connector is AMP series Superseal 1.5 (4-pin).
Where to get the terminal for OMVL and others.
Puzzling over where to find the connector for HBO diagnostic cable OMVL, I came to the conclusion that it is unrealistic to find such a connector... BUT, while doing a small revision of the wires, I came across a wonderful thing. Power connector motherboard from an old 300 watt power supply, an old system unit. and lo and behold! This connector fits with some modifications. Namely: first of all, you need to find a number of pins of the desired shape and then cut off the rest, unnecessary part of the connector. small photo report. I apologize for the photo quality...
P.S. It is important that the pin configuration is exactly the same as on the factory cord.
Manufacturing diagrams and cable testing for HBO
How to assemble HBO diagnostic cable on Zenit and Diego Leonardo, Voila Plus, Millenium, Bingo, BRC, Diego, AKME, Digitronic, Vector, Altis, Agis, Zavoli, Nicolaus, Tartarini, Autronik (A-mon), Lovato (Lov-Eco2), Les 98 ( Landi).
I was faced with the task of collecting HBO diagnostic cable to Zenit and Diego (cable according to pinout not suitable for STAG, +12V and Gnd need to be swapped ). I started poking around on the Internet and found a clear answer - “take a k-l-line adapter and use it.” I assembled the adapter from the master kit and let’s connect it, but it doesn’t work even if you crack it!!!
I dived into the Internet and it turned out that all HBOs have a regular RS232 COM port. RS232 implies signals with amplitudes from -12 to +12 volts. Moreover, logical “1” corresponds to the level -12V, logical “0” - +12V. This is necessary for noise immunity; signals “around zero” are considered noise and are not used. There are no such signals in the gas brain block itself. Such (or compatible) signals exist (still occur) in computers, but in modern laptops They are not here.
In the gas control unit, the interface has output signal levels (roughly, not really true) “0”=0V, “1”=5V (TTL levels). For this you need a TTL level converter for max232. This is exactly the microcircuit that is in data cables for LPG Lovato.
Photo of disassembled HBO cable Lovato.
- Chip MAX23
- socket for the MAX232 microcircuit (if you solder the wires directly to the microcircuit, you can damage it by overheating it with a soldering iron or by accidentally static voltage, so we buy a socket)
- Diode 1N4004 (wasn’t in the store, bought 1N4005)
- Voltage stabilizer L7805CV
- Capacitor 470uF 16V
- Capacitor 47uF 16V
- 4 capacitors 10uF 16V
- DB-9F socket 9 pin (com port female)
I have a cord lying around at home from a Siemens DCA-510 on a PL-2303 chip, let’s tinker with it and lo and behold, it works, the software sees HBO.
And so in order - USB cable Any COM port will suit NOKIA DKU-5, CA-43 CA-45, etc., set the speed to 9600.
How to check if the cable is working - take yours cable connect to the computer, close RX and TX, open HyperTerminal in Windows XP, in Windows 7 there is no HyperTerminal, but there is an option to copy two files hypertrm.dll hypertrm.exe from Windows XP to the same place and run it and everything works too
Open, check your settings, set everything to default in the system, then launch (Start -> Programs -> Standard -> Communications) HyperTerminal.
Set the default speed, as in the picture all the settings.
If you did everything correctly, the program will print the characters that you enter from the keyboard.
This is what the terminal looks like cable for HBO AKME diego:
Terminal k HBO Zenit. Same terminal for AC Gaz Stag ( but +12 and Gnd need to be swapped ):
And here is the pinout of the DR-73 cable, this is a Stag (Digitronic) cable plus OMVL Lovato. Only +12 V and Gnd are shown.
Nothing bad will happen if you confuse RX and TX. Be careful, measure with a tester where you have +12V and don’t stick anything there (in the native wire, black is always then zero, and red is +12V) there is nothing complicated here, find 3 wires (zero) (RX) and (TX ) your tester will show some symbolic voltage greater than zero. It is better to remove the key from the ignition before connecting cable to HBO then connect the USB and turn the key so that the dash lights up and then launch the program.
In any case, nothing bad happened to me when I connected the USB and then the diagnostic connector, but it’s better to do as I wrote above.

string(10) "error stat"
Gas equipment, or, as popularly known, LPG, is a rather complex system. various devices, which is aimed at supplying gaseous fuel to the engine. In addition to the main structural elements such as a gas cylinder or overpasses for supplying it to the engine, the system has an electronic “brain”. The latter allows you to control the HBO and diagnose its malfunctions in a fairly convenient mode. Diagnostics and configuration of equipment occurs by connecting its “brain” to a special cable. We will talk in more detail about the purpose of such a cord, the principles of its operation and use in the material presented below.
Design and purpose of the device
It's no secret that almost all components of the structure modern cars have electronic control. Gas equipment of machines is no exception, therefore, to control its operation, a special control unit is used, which is the electronic “brain” of the unit. A cable for HBO is required to control this unit in a way convenient for humans, that is, by special program on the computer.
Gas equipment is connected to electronic computer through a special diagnostic connector, which, as a rule, is located near the control unit. Such a connection allows you to achieve the following goals:
- First, set up the HBO, which is necessary for stable proper operation node;
- Secondly, install new program for gas equipment, which is needed when changing its configuration or wanting to configure the operation of the unit in a radically new way;
- And thirdly, carry out other diagnostic work, which is quite important for organizing stable and safe operation of the gas equipment.
Let us repeat, diagnostics and configuration of equipment occurs through a computer, so to organize them you need:
- Get a cable for HBO diagnostics from the exact manufacturer that is installed on your vehicle;
- Prepare a laptop;
- Download and install the appropriate one on it software to carry out the necessary manipulations.
It is worth noting that most types of gas installations known throughout the world, for example from the manufacturers “Stag”, “Digitronic” and “AGIS”, operate on control units similar in design and principles of software organization, so find a universal cable for gas equipment in stores or making it yourself is not so difficult. Some experts in the “gas balloon” business, of course, do not recommend the use of such a device, but practice shows that using them is completely safe, because there are software failures in the operation of the electronic “brains” different types they don't call. By the way, universal cables have already been tested more than once when setting up the same gas systems from Stag, Digitronic and AGIS.
HBO compatibility with specific cables
It was already mentioned earlier that, despite the general similarity in the structure of control units of different gas equipment, specialized cables are used to configure them. This is largely due to two features of gas equipment:
- Differences in their pinout, which requires individual connection of the cable with a specific type of gas equipment;
- Incompatibility software, used by different manufacturers of gas equipment in their control units.
Of course, you can buy a universal cable, but it is noticeably more expensive than any profile cord, so for individual use it is better to purchase devices designed specifically for your type of gas equipment. By the way, the cost of the latter is in the range of 500-1500 rubles, while universal cables are sold at a price of 2000.
Learn how to make a universal cable with your own hands
If desired and having some skills in electronics, any motorist can make a universal cable for HBO with his own hands. IN standard version to achieve this goal you will need:
- telephone cables of the “DCA-510”, “DKU-5” or “CA 42-45” format on “PL-2303” or “MAX232” chips;
- soldering iron;
- insulating tape;
- 3-wire wire;
- a chip for connecting the made device to a standard connector of the HBO control unit.
The procedure for creating a cable is as follows:
Having prepared the device, it can be used for its intended purpose. For general information Let's look at the order of its use, which consists of executing the following algorithm:
- Prepare your laptop;
- Download and install a diagnostic program on it specifically for your type of HBO;
- Connect the equipment control unit with the prepared cable to the laptop;
- Run the diagnostic program;
- Swipe necessary settings or diagnostics of HBO, then disconnect the created network.
As you can see, there are no particular difficulties in using and creating a cable for gas equipment. It will be especially easy for those motorists who will use the material presented today in the process of diagnosing or setting up LPG. We hope the article was useful to you. Good luck with the repairs and on the roads!
