Buy DR-309: Second Indication Post and Course Data Source
Photo model from our catalog. configuration and the set of the proposed delivery are agreed separately.
Request price and kit DR-309An additional post needs a clear course pointer, but buying a single display doesn’t describe the entire system. The DR-309 is considered together with the data source, communication link, and installation site. For ordering, it is useful to divide three tasks: where the course comes from, how the data is transmitted, and what the operator should see.
Repiter and source of the course - separate positions
According to the manufacturer's description, the DR-309 shows the received course data on the card and the LED indicator. It receives information in the NMEA quotation from a digital source. Therefore, the application includes the exact source model and documentation, not just the name of the new repeater.
If the source is saved, write down the output used and the connected consumers. For a new project, list all the posts that need data. The possibility of adding the next device is checked by the composition and interfaces of the entire system, not by the presence of free space on the panel.
What information connects the two devices
| Node. | Data for the application | What to agree on |
|---|---|---|
| Source of course | Model, output, format of transmitted data | Suitable signal for selected repeater |
| Line | Interface, cable, length and existing connections | Retained parts and additional elements |
| Indication post | Place, review, power supply and fastening | Configuration |
NMEA in the title is not yet complete the selection
The manufacturer's page lists accepted DR-309 quotation HDT, HDG and HDM. Tell me what the source is and what interface is used. The data format and the electrical connection are checked separately. The image of the same course on the two instruments also does not explain the origin of this data.
Ask to describe which source will be displayed on the new post and how the operator recognizes it. For multi-source systems, a consistent operating scenario is important. Do not transfer random settings of another object to the specification of your installation.
Replacement of the repeater without complete alteration
Take a picture of the old appliance, its nameplate, rear connections and mount. Attach the diagram of the current line and indicate known malfunctions. The quotation can then be divided into the new DR-309, the retained items, and the required changes. Diagnostics of the source of the course and cable are agreed separately from the purchase of the indicator.
When replacing due to incorrect readings, it is important to report how other consumers of the same source behave. This is useful initial information for a specialist, but in itself it is not a definitive diagnosis. A new repeater is selected for a confirmed system task.
Acceptance at an additional post
In advance, determine the selected source, verified data and the procedure for confirming the work. Fixing, power supply and line are performed according to documentation and project. Agree on the documents and save the final scheme: with further expansion, it will allow you to understand where each post gets its course.
In the goods block below DR-309 is indicated first. The NGC-3000, NGR3000, and JLR-21 navigation instruments can be discussed in separate project items; the compatibility of each combination is confirmed by documentation, output-specific functions, and agreed data.
Order DR-309 in Russia and Kazakhstan
To buy DR-309 in St. Petersburg, Moscow, Rostov-on-Don, Kazan, Krasnoyarsk or Vladivostok, send the scheme and the city of receipt. For Almaty, Astana, Aktau and Atyrau, specify the destination country. Price, availability and term depend on the agreed configuration and order composition.

Questions before buying
Is DR-309 the source of the course?
In the manufacturer’s description, it displays data received from a digital source. The source and its output are specified separately.
Is it enough to write NMEA in the application?
You need a source model, a really transmitted quotation, the interface used and information about the communication line.
Can I just replace the indicator?
First, the applicability of the stored source, line, power supply and mounting is checked. The necessary changes are included in the specification.
