Introduction
General
T o run the After Sales SW , a parallel port software protection device (PKD–1) has to be
connected. The user can use WinT esla functions in modules for testing NME–3 mobile
stations (MS). The test functions send test messages from PC to MS and receive results
and show them in the PC display. The messages can be sent via M2BUS.
Note: if this software is to be run on laptops, the power saving feature MUST be switched
off.
Hardware requirements for Windows 3.1x
The recommended minimum hardware standard to run Service Software is any computer which is 386 33 MHz or greater with at least 4 MB of memory and VGA type display
(640 x 480). This assumes that only the WinTesla with After Sales Support Modules is
active, i.e. other Windows packages are not running in the background.
Hardware requirements for Windows 95
The recommended minimum hardware standard to run Service Software is any computer which has Pentium processor, memory 8 MB and meets HW requirements recommended by Microsoft.
Software Environment of the Support Modules
The Service Software user interface is intended for the following environments: Microsoft Windows 3.1x (enhanced mode) and Windows 95 environment running in enhanced mode. Support for Microsoft NT may be added, if required. Detailed information
about Windows and application usage can be found from the Microsoft Windows Version 3.1 Users Guide chapter one (Windows Basics) and chapter two (Application Basics).
As an ordinary Windows application, the main idea in the user interface is that selections
are made with menus, push buttons and shortcut keys. Selections can be done by using
keyboard and/or mouse. There is always a status bar displayed at the bottom of the
main window which contains information about current actions.

Required Servicing Equipment
– Computer: At least IBM 80386 or compatible with one unused serial
port (COM1 or COM2)*), one parallel port (LPT1), hard disk recom-
mended
– Operating System: DOS Version 3.2 or later
– If PCLStart in use: DOS 6.22 and IBM 80486 or compatible
– Display: Any 80–character text display
– Service software version for 3.5” disk (product code: )
– Software protection key PKD–1 (product code: 0750018)
Detailed equipment is shown on
*)
Note: 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.

Installation
Mechanical Connections
Caution: Make sure that you have switched off the PC and the printer
before making connections.
Caution: Do not connect the PKD–1 key to the serial port. You may
damage your PKD–1 !
The software controls the phone via a separate adapter connected to the serial port of
the PC, and to the telephone’s M2BUS (DAU–9S).
Attach the dongle PKD–1 to the parallel port 1 (25–pin female D–connector) of the PC.
When connecting PKD–1 to the parallel port, be sure that you insert the computer side
of the PKD–1 to the PC (male side). If you use a printer on parallel port 1, install the
PKD–1 between the PC and your printer cable.
The PKD–1 should not affect devices working with it. If some errors occur (errors in
printing are possible) please try printing without the PKD–1. If printing is OK without the
PKD–1 please contact your dealer . We will offer you a new PKD–1 in exchange for your
old one.
Installing the Software on PC Hard Disk
The program is delivered on a diskette and is copy protected with a dongle PKD–1. It
must be present in parallel port when using Service software.
The program can also be installed on the hard disk, which is recommendable to obtain
a maximum data access rate.
Keep the original diskette safe to enable upgrading of the program !
If you plan to use PCL Start service software, you must install it before installing Service
software, see PCL Start installation instructions.
To install the new Service software program, follow the steps below:
1. insert the new Service software diskette
into drive A: of your computer
2. start Windows, and open File Manager
log into drive a:
type
A:
and press <Enter>
3. start SETUP.EXE and

Tuning Steps
1. RX Calibration (AGC + AFC)
Procedure
Follow the steps described in chapter ”Service Software Instructions”
section ”RX calibration... command”.
Software reports the following:
AFC init value
AFC slope
PSW slope
AGC DAC values and the corresponding voltages for each gain step (0 57 dB)
Technical Documentation
Limits for the reported values
If everything went well the reported values should approximately be the
following:
Parameter Low limit High limit
AFC init value –80 80
AFC slope 135 230
PSW slope 250 350
AGC 0 dB 440 740
AGC 57 dB 60 360
Difference between the two neighbour
AGC steps
10 20
Troubleshooting
If the calibration does not succeed the software normally reports ”Unable
to read data from phone” or ”Failed to set high reference” or ”Failed to set
low reference”.
Page 10
In this case check first the basic functionality of the receiver chain: RF
generator frequency set as in the calibration and level for example to the
high reference value.
Then go to the RSSI reading menu (under RF controls). If the reading is
very low there is something broken in the receiver and must be found by
measuring voltages and signal levels at different places (information of
these can be found elsewhere in this manual).
Issue 1 10/99
PAMS
NME–3
Technical Documentation
If the RSSI reading seems to be within 5 - 10 dB the same as the RF input
level check that the VCTCXO (G650) frequency is close enough the
wanted frequency. This is most easiest done by measuring the UHF VCO
(G550) frequency because the absolute value of the deviation is biggest
there. In the GSM mid channel the UHF–VCO frequency should be 1018
MHz. If the deviation is bigger than about +/–20 kHz it is probable that the
VCTCXO is not operating correctly.
If both of these (RSSI reading and the frequency) seem to be correct and
calibration still fails the most probable reason is that there is a little lack of
gain somewhere or the AGC gain control slope in N600 is out of the limits.
This can be verified by changing the generator reference levels from the
demanded ones in the calibration procedure in 1 dB steps up and down. If
the calibration goes through with some reference levels the corrective
action is most probably changing N500 or N600.
Service Software Instructions
2. Alignment of Transmitter Power Levels
Equipment:
– Pulsed power meter or spectrum analyzer and 10 dB attenuator.
– MSJ–13 voltage source within 9–15VDCV.
The following settings for the spectrum analyzer are recommended when
aligning the power levels: zero span, resolution and video bandwidths 1
MHz, input attenuation 40 dB, sweep time 1 ms, video triggering.
Procedure:
Follow the instructions given in chapter ”Service Software Instructions”
section ”TX power... command”.
For GSM the alignment channel is 60 (902 MHz)

– After finding both minima change ”TX I DC offset” by step or two from
the current value to both directions to see, whether better minimum
