4. FUNCTION DESCRIPTIONS
This chapter describes the application of the Tests available in the MKII Tachograph Programmer,
gives details of the connections required for each and provides a step-by-step instruction guide for
each function for the inexperienced user.
4.1
Enter PIN Code.
In order to read or inject pulses or to write data via the front programming connector of a digital
tachograph, the tachograph must be put into calibration mode. Calibration mode consists of a
valid workshop card being inserted into the tachograph, and a PIN code entered.
In the case of the SE5000 the PIN code can be entered either through the tachographs keypad, or
via the programmer. A PIN code function is available through the Main Menu, but the programmer
may also prompt for a PIN code if a function is attempted while the tachograph is not in calibration
mode.
Entering a PIN through the programmer operates in a similar manner to SMS messaging.
Continually pressing a key will cycle through a list of characters under that key. Pressing a new
key or waiting for approx 5 seconds, will move to the next character. Pressing Enter will ask the
tachograph to authenticate the PIN. If too many characters are entered, use the arrow and delete
keys to correct.
The list of characters under each key is detailed in Annex D
In the case of the DTCO the PIN code can only be entered through the tachograph keypad.
Insert the workshop card into the tachograph, and insert the front connector from the programmer
into the Tachograph.
From the MAIN MENU select ENTER PIN
using the
←
and
→
keys. Press ENTER.

W-factor (Vehicle Characteristic Coefficient) Determination
The MKII Tachograph Programmer can use three different methods of determining the W-factor
for a vehicle, namely Rolling Road, Fixed Distance #1 and Fixed Distance #2. In each case the
W-factor (revs/km for a 2-pulse sender or pulses/km for other senders) is determined and
displayed. Where appropriate the correct setting of the tachograph DIL switches is indicated.
The choice of the method to be used will depend on the other facilities available. However, the
connections between Programmer and tachograph or sender are the same for all three of the
calibration methods used:
