1. INTRODUCTION
An intelligent fiscal module FM 3000 is going to enable the use of your computer and open
homologised cash register system. An open cash register system is a system that enables to make
operations on PC cash register and also operations that are not related to sale as are letters and faxes
writing, accounting of the salaries and so on. In other words it will extend computer attributes with
the cash register system according the Regulation No. 55/1994 of the Statute roll. The main
advantage of the fiscal module is that in the past, you used for business software convenient for you,
you do not need to replace it with another, homologised software. It is only necessary to put
managing ESC sequences into printing masks of the direct sale, which are used for the
communication with fiscal module FM 3000. By means of this simple step is your computer prepared
for the usage as a cash register system.
2. The conditions for the certificate acknowledgement
Due to the Certificate for cash register system is not issued for fiscal module but for the whole set
(the computer cash register system), user is obliged to:
During the whole period of the cash register system registration on the Tax office is necessary to use
only the devices with the electric homologation from the Slovak State Laboratory, particularly for
computer, screen, and also for printer of the bills. The user guarantees that these devices would not
be replaced with the ones that are not electrically homologised. When used other than electrically
homologised device in the set of the computer cash register system, the user is endangered with the
sanctions due to certification conditions violation, and also user is endangered with the notacknowledgement of the certification with all possible consequences. In case you are obliged backup
sale records, the tape has to be stored on dark and dry place because of the data has to be readable for
five years from the date of the receipt (stub) issuance. If is the control tape stored in electronic form,
data has to be achieved on permanent inerasable media CD ROM for e.g.
3. General information
The device is introduced under a business name FM3000. Device FM3000 is an intelligent fiscal
module with its won processor that communicates with the computer through serial interface RS232
or USB 2.0 interface. FM 3000 sends processed documents directly to connected printer. Module
enables and independent sales records administration and following calculation of balances, which
are stated in Regulation no. 33/1994 of the Statute roll. Module does not communicate with computer
if the printer is disconnected for document printing. Fiscal module is a computer using input and
output peripheral units of superior computer, but is entirely independent from it. If we want to define
functions of the module FM3000, it is basically a small electronic cash register without keyboard,
display and printer. Fiscal module is powered by source of superior computer. Module does not have
own switch, so it is turned on/off when is superior computer or source turned on/off too.
Since the module communicates with a superior system through standard serial interface RS232, the
best option of the installation is in three basic areas:
n UNIX, QNIX and terminal networks (external version),
n Computer network Nowell,
n Applications, where the software used for sale and stock records is suitable for the user and
user intents to use it in future without a supplementary homologation of the cash register
system;
n For the users who want to expand the attributes of their computer with ones of cash register
that meet the standard of Regulation no. 55/1994 of the Statute roll, about ways of keeping
sale records using a cash register.

4. Attributes of the fiscal module
From the construction point of view, it is an independent microcomputer system, which passes only
the correct data and registers them in a voltage independent memory EEPROM. This memory is not
erasable, without the fiscal module opening. Fiscal module cooperates with all operation systems,
which are able to communicate through serial port RS232 (MS DOS, MS Windows 9x, 2000, XP,
OS2, UNIX, QNIX ...). Since fiscal module does not require any resident program neither a link
module it is not dependant on a programming language used for creating of a cash receipt (slip, stub).
F3000 controls and records independently from computer program only tax correct data sent to the
receipt printer. So far, the problem consisted in homologation of UNIX cash register systems that are
not adjustable for fiscal module installation, because the terminal does not have disc neither free slots
for expansion cards. Based on these facts, VAROS union started to develop and manufacture an
external kit (set of components, which modifies the internal module to external). FM 3000 is placed
between printer and computer. The module can download characters sent from the computer to
printer and it stores them in its memory and evaluates them according to standard ESC sequences
(control characters). If the data are correct, it processes them and sends them to the printer. At the
same time it actualises figures in tax registers (GT1, GT2, GT3, ordinal number of receipt, taxable
income for 0% and 19%). FM3000 enables processing of daily, monthly and annual balances, while
all the data needed for executing these balances derives from its internal memory and not the
computer memory. All tax data are stored in the non-erasable memory and whatever access or change
is not possible unless the seal is damaged and module opened. Every authorized service engineer has
their own password assigned and through which he can alter the data. That means it is possible to
identify the last person who changed the data, which are not accessible to a common user, who can
access the tax data only by damaging the seal.
The above-mentioned brief description results in necessity of printing masks modification enabling
printing of receipts on printer, It is self-active in printing the header, date, time and numbering of the
slips. It also calculates VAT on the receipts and balance sheets, continuous daily, monthly and annual
balance values, as well as values of GT1-GT3 receipts printing program only sends basic information
and through managing ESC sequences, it informs FM3000 about their importance. Said in the other
words, if you are satisfied with your current business managing software and the program providers
are willing to modify printing output slot in accordance with this guide, the installation of FM3000 is
and ideal solution for you.
5. Technical description
Fiscal module is a device that monitors and stores data of cash receipts. Fiscal module on the base of
input data evaluates type of input file. If there is a cash receipt on the input, connected printer prints it.
If there is not a cash receipt or if there is a file that fiscal module is not able to identify, document is
filtered and printer does not print it.
Fiscal module is a device with own processor, memory modules, and timer and input/output ports.
Incoming input data are evaluated by program that is permanently stored in the processor of the fiscal
module. According to the processor evaluation are particular fiscal data stored in voltage independent
memory with 64MB capacity.
In this memory are stored daily monthly and annual balances. Balances are stored in memory
permanently. It is possible to print any balance using command from superior application.
In memory is created also so-called “electronic control tape” Particular receipts are stored through
system FIFO and after overflowing capacity system overwrites the oldest receipts. Printing copy of the
receipt from control tape can call command from superior application.
