Document structure

Comments and
suggestions

The system description was generated according to the following criteria:

• Empirical values recorded from function descriptions of previous versions

The system description can always be improved since it is not necessarily
complete in all aspect s. T herefore, I hope there will be com m ents and su g­gestions from the field. As far as possible, I shall try to incorporate any com­ments and suggestions into the document.

Please w rite to me wit h you r s uggestions for improvement. Many s ugges­tions, while th ey may app ear improb able at t he outset, ca n be the key to sud­den "i ns ight" for a service engi neer.

Many thank s to all of you participating in the preliminary pha s e for your co m ­ments and suggested improvements.

Localization

US localization

The "LITHOSTAR Multiline system" is a multifunction workstation for diagno­sis and therapy involvin g extrac orporeal shock wave lithotr ips y w it h radio­graphic and optional ultrasound imaging. The system is excellent for the
treatment of stones throughout the entire urinary tract as well as for all suit­able auxiliary treat m ents required.

Laser light loc alizer for preposi tio ning the patient

The system includes an undertable X-ray unit permanently mounted on a C­arm. In addition to conventional use of the system for diagnostic purposes

(0°), the C-arm can be moved orbitally for the purpose of stone localization
(-10°/30°).

The focal point of the shock wave head (maximum shock) is located in the
center of both localiz at ion ranges (isocenter). In line technology enables
observation of ston e f ragmentati on t hrough the sh ock wave source.

Additional stone localization is made possible via the ultrasound monitor by
inserting an ultrasound probe in the shock wave head (Inline Position).

Oper ating modes

The system is controlled at a control console via a PC with keyboard and
mouse as well as a tableside control. A tableside control is also available on
the patient table. The table can be lowered to 720 mm to provide comfortable
access for the p at ient.

A tableside control is loc at ed on the Ultra so und unit for important fu nc t ions
such as: probe movement, shock wave release, shock wave counter, probe
angle display.

Hardcopy doc um entation is als o possible us ing film
(cassette size 35 x 43 cm) via an insertable cassette holder.

To guarantee system functions, only service engineers with work authoriza­tions for the LITHOSTAR Multiline may service this system.

Two operating modes are possible:
Diagnostic mode (table insert locked in)

Therapy mode* (table insert removed)
*with X-ray or ultrasound localizat ion

The most important tasks are: basic initialization and hardware tests and
time-out m onitorin g (establishin g c ontact). Error handling is import ant when
serv ic e w ork is being performed.

Hardware errors: LED’s flash in all keys. (approx. 5 Hz)

Establishing contact: Initial contact. LED’s flash sequentially in keys
Polling time out: LED’s in all keys flash. (ap prox. 1 H z )

DUEP Interface 2

DUEP

Function

Serial dat a t rans m ission bet we en the master (Com con t roller D6) and th e
slaves (e.g. operatin g panels or image memory, etc.) occurs via a Siem ens­standarized data transmission protocol (DUEP).

The DUEP inter face is a 20mA current lo op.
Each curr ent loop has an LED as indicator on bo ard D6.
If the LED is "ON", it means: the loop is connected and 20 mA are present.

DUEP 1: Current loop 1 Tableside controls (system, US unit, NBFFT)
DUEP 2: Current loop 2 Operating PC
DUEP 3: Current loop 3 Shock wave system
DUEP 4: Current loop 4 Tableside control at the PC
DUEP 5: Current loop 5 Image memory

Telegra m s co nt aining comm ands to be performed are sent via the s e c urrent
loops (e.g. selecting functions or increasing values etc.). Even if no com­mands are p r ese nt , th e COM c ont ro l ler (D6 ) co nt i nuo usl y ch ec ks t he f unc ti on
of the interface. If n o s igns of life are present, the COM c ontroller trans it ions
to a security level and sends a failure message to the Host (D1). An error
message is displayed.

Possible
causes of error

Connection to the slave has been interrupted (e.g. damaged cable). The LED
goes out.
Connection to the slave has shorted out.
Assembly for resp ec t ive DU EP is defective.

The se r vi ce engineer (FSE) can d eactivate slaves via
the service program. This can be useful during error
localization. This method should, however, only be ini­tiated by experienced service engineers. For example,

it is typical to see the LED’s flash sequentially in the
operati n g keys if initial co n tact from the op er ating
panel (D41) to the master (D6) does not occur.

NOTICE

Step 1:

Switching the system off from the generator provides
additiona l sa fety for the servi ce engineer becau se the
system cannot be switched back on from the control
console.

• Starts bo ot soft ware

• Initialize operatin g system

• Processor system self-test

Simply stated, this first step initializes and tests the HOST board D1.
All subsystems are initialized in parallel.

The PC can be connected following completion of the first step.
Step 2:

• Starts initialization tasks

The version number of the HOST software is compared with the version num­ber in the EEPROM.

Establishing contact

Siemens AG Register 7 RXL2-120.041.01 Page 3 of 6 LITHOSTAR Multiline

If there is a discrepancy, the HOST will send an error message and will transi­tion to a wait lo op. Onl y by dow nloading th e operating sof t war e in t he
EEPROM is it pos s ible t o c ontinue the initializatio n.

Step 3:

• Initialization routi nes of the subsystems

Contact with the subsystems is established in this part of the initialization. In
principle, the subsystem must contact the HOST after initial contact is estab­lished and vi c e versa.
As a rule, three attempts will be made to establish contact to the other if
errors occur during this data exch ange . If these atte mpts fail, the systems will
transition t o a s ec urity level and an error messag e w ill be displayed.
