Introduction
The Nokia 9000 service software is a dual purpose package designed to
test all CMT and PDA functions by means of menu driven user interfaces;
it is also used to download new flash images. The software requires that a
dongle, PKD–1 , be fitted to the PC parallel in order to enable software
functionality. This chapter details both service and flash downloading
functions in separate sections.
Required Servicing Equipment
– Computer: IBM PC/AT or compatible with at least one, unused serial
port, COM1 or COM2 (see note below), one parallel port (LPT1), hard
disk recommended. DOS Version 3.2 or later
– Display: Any 80–character text display
– Service software program, LSD–1 for 3.5" disk (product code:
0774057)
Note: Two ports are preferable. A number of PC's of an older generation use the Intel,
National Semiconductor, or United Microelectronics IC 8250 as the serial port UART. This
is a comparatively inefficient circuit for current purposes and does not necessarily support
the M2BUS adapter at 9600 baud. The newer UART's NS16450 and NS16550AF of
National Semiconductor offer solutions for these problems.
A list of service tools ,accessories and part numbers are given in Chapter
9 of this manual.
Note :– Screen shots for both PCN and GSM units are, in general, universal. Where
they differ an extra screenshot is shown.
