User Guide

This User Guide explains how to set up and use the Digidown to download digital tachograph vehicle unit (VU) and tachograph card data

Overview

Digidown is a Digital Tachograph Download Device that allows you to:

Download Vehicle Unit (VU) data from a digital tachograph
Download a Driver card via the tachograph
Transfer files to your computer

Before First Use

Insert the SD card into the side slot until it clicks. The notched corner should go in first and point toward the bottom of the device.

Replacing the SD Card

If you ever need to replace the SD card, get in touch with us. Digidown Plus requires them to be 2GB or smaller and formatted as FAT -not FAT32- and they are hard to come by.

Download from a tachograph (VU)

Make sure an approptiate card is insterted (Company, Workshop or Control card) into the tachograph (slot 2).
(If your vehicle requires it) Switch Ignition ON
Connect Digidown to the tachograph 6-pin front socket. It will be behind a flap or behind the printer drawer.
Check that the LEDs briefly blink in sequence. This means the device is ready.
Press the appropriate download button:
1. ALL VU → for a full download (slowest, can be 30+ min)
2. LATEST VU → for a faster download (configurable, see Configuration Utility below)
3. CARD → for a Driver card inserted in the tachograph (slot 1) download
Check that the relevant LED is flashing 2 per sec. This indicates the download has started.
Wait for the final LED status:

Do not unplug during download

Remove SD card (press in to release until it clicks) and insert directly into any SD card reader.
