Digital Tachograph Combined Download Device
Operating Instructions
Introduction
The Digidown Plus downloads data from digital tachograph vehicle units (VUs)
from all current tachograph manufacturers. Data downloaded from the VU is
stored in a Secure Digital memory card, normally known as an SD card.
Three types of VU download are available:
ALL VU
Downloads all contents from the VU
LATEST VU
Programmable1. Options include the last 1, 2 or 3 months of
data plus a selection from events & faults, detailed speed and
technical information and can include a download of a Driver
card inserted in the VU.
CARD
Downloads a Driver Card inserted into the VU
Pressing the relevant button starts the Download. Download status is indicated
by the 3 LEDs positioned alongside the buttons.
The Digidown Plus can also download any tachograph card directly into the unit
via the card reader slot in the side using AA batteries or by powering the unit
through a USB cable. The download starts automatically when the card is
inserted.
Initial Set Up
In order to operate successfully, the Digidown Plus requires an SD card to be
inserted into the slot in the side of the device. A suitable ready-formatted SD
card is supplied with the unit2. When a suitable memory card has been inserted
into a Digidown Plus and the Digidown Plus is connected to a VU it checks the
card format and then indicates that it is ready for use.
In order to read tachograph cards direct into the unit without a USB power cable,
a pair of AA-size batteries is required (supplied with the unit). Please observe
the correct polarity when inserting the batteries.
Insertion and removal of the SD card
When in use, a suitable SD card must be inserted into the slot in the side of the
Digidown Plus. To insert the card, push it into the slot in the side of the
Digidown Plus until it latches in place. To remove the SD card from the Digidown
Plus (for instance in order to read it using a different memory card reader) the
protruding end of the memory card should be pushed back into the Digidown
Plus. This will release the SD card and it will spring out for easy removal. DO
NOT try to remove the latched memory card by pulling on the end of the card.

Please contact your dealer to discuss the options available.
Whilst the Digidown Plus will work correctly with most types of SD memory card (provided that they are
formatted FAT16), Lisle Design can only guarantee operation with those memory cards supplied by Lisle
Design.
VU Download Process
Please note that for any download from a digital tachograph VU to work, a
Company, Workshop or Control card must first be inserted in the VU. In the case
of some VUs the vehicle ignition must be switched on.
Connect the Digidown Plus to the 6-pin Download connector on the front of the
VU. Please note that the Digidown Plus should NOT be connected to an analogue
(chart-recording) tachograph.
On connection, the Digidown Plus will check the presence and format of the SD
card and then indicate that it is ready for operation by blinking briefly each of the
LEDs in turn. Pressing any of the buttons will initiate the download indicated by
the button’s label.
During download, the LED by the button pressed will flash repeatedly about twice
each second. Successful completion will be indicated by the LED blinking briefly
about once every second. Please note that the download of data from a VU can
take a considerable time, potentially in excess of 30 minutes. Downloading using
‘Latest VU’ can reduce the download time considerably.
NOTE: DO NOT disconnect the Digidown Plus or remove the SD card during a
download. Doing so may cause file errors on the SD card.
Driver Card Download Process
Driver cards can be downloaded via a VU. In this case the relevant driver card
must be inserted into one slot of a VU and a Company, Workshop or Control card
must be inserted into the other slot. Once again the Digidown Plus should be
connected to the 6-pin download connector on the front of the VU.
Once the Digidown Plus is connected and indicating that it is ready to download,
press the ‘Card’ button on the Digidown Plus to start downloading the driver card
in the VU.
During download, the LED by the button pressed will flash repeatedly about twice
each second. Successful completion will be indicated by the LED blinking briefly
about once every second. Download of data from a driver card in a VU generally
takes a small number of minutes to complete.
The Digidown Plus provides the facility for driver, company, control and workshop
cards to be read direct into the unit. With the Digidown Plus disconnected from
other equipment, insert the card to be downloaded (chip down) into the smart
card slot in the side of the unit. The unit will first check that the SD card is
satisfactory and will then download the tachograph card.
During card download direct into the unit, the LED by the ‘Card’ button will flash
repeatedly about twice each second. Successful completion will be indicated by
the LED blinking briefly about once every second. Download of data from a
driver card direct into the Digidown Plus takes in the region of 30 seconds
(depending on the tachograph card).
A driver card (or any other type of tachograph card) may be downloaded into the
Digidown Plus and into its SD card whilst the unit is connected to a PC’s USB
port. In this case the required power is taken from the USB connection. If the
Digidown Plus is always connected to a USB port when downloading tachograph
cards then the internal batteries are not required.
Reading the SD card
The SD card can be read via the USB port on the Digidown Plus1. Once
connected to a PC via the USB port, the Digidown Plus will appear as a standard
removable disk drive.
Alternatively data on the SD card can be read and/or copied by removing the SD
card from the Digidown Plus and plugging it into a separate SD card reader
available from Lisle Design or from major computer or camera shops.
Mounting Bracket
The Digidown Plus may be supplied with a bracket allowing the unit to be fixed
down to a counter or other horizontal surface. A second (smaller) bracket is
supplied to cover the memory card slot.
When installing the standard mounting bracket, please see the diagram on the
last page. The smaller bracket should first be attached to the larger bracket using
the (M3 x 10mm) countersunk screws and the 5mm nylon spacers. The bracket
should then be attached to the selected surface, e.g. counter, shelf etc. with
appropriate screws (not supplied). The Digidown plus unit can then be attached
to the main bracket using the supplied pan head screws (M3 x 6mm). Note that
the memory card cover may be omitted if access is required to the memory card
whilst the unit is attached to the bracket.
If a USB cable is to be attached permanently to the Digidown Plus whilst attached
to a mounting bracket, then the cable may be passed through one of the holes in
the bracket before the unit is attached to the bracket.

‘Download Fault 12’
When downloading data from some SiemensVDO digital
tachographs the message ‘Download Fault 12’ may occasionally be shown on the
tachograph display. This can safely be ignored. Allow the download to finish and
then press ‘OK’ to cancel the error message.
Choice of SD Memory Card
The Digidown Plus will work successfully with most types of SD memory card. A
few SD card types are unfortunately not suitable as they do not conform fully to
the SD card specification. Cards supplied by Lisle Design are to be preferred as
they have been selected for optimum performance in this application.
2Gbyte memory cards are supplied as standard by Lisle Design (although lower
memory capacities are entirely adequate for this application). Larger capacity
memory cards are not suitable for use with the Digidown Plus.
SD Card Formatting
For any SD memory card to work with the Digidown Plus it must be formatted
FAT16 (which Windows calls ‘FAT’).
When a newly formatted SD card is inserted into a Digidown Plus and the unit is
connected to a VU, the format of the memory card is first checked. The
Digidown then creates a directory structure on the card.
Two top-level directories are created:
‘DIGIDOWN’ and
‘UPDATES’
‘Digidown’ has 2 sub-directories:
‘VU’ where VU downloads are stored and
‘CARD’ where driver card downloads are stored.
This process is automatic and generally takes just a few seconds.
Downloaded Data
The downloaded data appears on the SD card in the ‘\digidown\vu’ or
‘\digidown\card’ directory depending on download type. The Digidown Plus unit
creates long filenames for each download, in the form of:
VU file: M_YYYYMMDD_HHMM_AA12BBB_xxxxxxxxxxxxxxxxx.DDD
M denotes a VU file. The next 2 sections are the date and time of the download.
This is followed by the vehicle registration (AA12BBB) and identification numbers
(xxxx...).
Card file: C_YYYYMMDD_HHMM_A_SMITH_xxxxxxxxxxxxxxxx.DDD
C denotes a card file. The next 2 sections are the date and time of the download.
This is followed by the driver name and number.
Alternatively the Digidown Plus can be programmed to use short file name
formats or alternative long file name formats.
Whatever the file names, the contents of the downloaded files are exactly
according to the digital tachograph regulations.
Choice of Batteries
Two AA-size batteries are needed to power the unit when downloading
tachograph cards direct into the unit. When downloading data from a VU or
reading the SD card via the USB port then the internal battery is disconnected
and power is taken from the VU/USB port.
The Digidown Plus is designed to be used with alkaline batteries. A pair of cells
will generally be good for downloading tachograph cards some 2000 times before
needing replacing.
Other battery types may be used provided that they supply in the region of 1.5V
per cell. The Digidown Plus takes a very small current whilst operating. There is
therefore little merit in using alkaline cells designed for high-current applications.
Rechargeable cells may also be used, e.g. nickel cadmium (Ni-Cd) or nickel metal
hydride (Ni-MH), but users need to be aware that many types of rechargeable
battery do not perform well in low current applications and may self-discharge in
a few weeks. There are also potential difficulties when they have been used a
few times as the capacity of one cell can end up quite different from the capacity
of the other. This will result in the battery life being much shorter than expected.
Upgrade of the Digidown Plus
The software within the Digidown Plus can be upgraded when appropriate without
the need to return it to a dealer.
Similarly the programming of the ‘Latest VU’ button can be updated without the
need to return the Digidown Plus to a dealer.
