7. CIRCUIT EXPLANATIONS

7-1. Power supply circuit

1) Diodes rectification bridge
By diodes rectification bridge, alternating
voltage is converted into DC voltage, and the
electrical voltage is done filtering of by
Capacitor C4.

2) Power supply circuit for B-6
The electrical voltage which puts in resistor 3
when line voltage includes anomaly changes,
and transistor Q1 becomes on status, and
CS signal is done outgoing of by this, and VP
is supplied than Power supply B-6.

Note: The component for connection isn’t equipped with in plant shipping.

(service arrangement)

7-2. DC/DC converter circuit

2SD721(Q2) is Power voltage control transistor, and electric power supply is supplied in DC­DC converter with 2SC3303(Q3). 2SC3303(Q3) does a work as oscillator. The frequency of
2SC3303(Q3) is controlled by signal done feed back of through RD27EB1.

[ Data reading procedure ]
When the CPU read the data of EEPROM, CPU send the CS signal and SK signal to EEPROM.

Then CPU send the address to EEPROM, and then EEPROM return the data to CPU.

[ Data writing procedure ]
When the CPU save the data to EEPROM, CPU sends the CS and SK signal to EEPROM.

And CPU send the address and data to EEPROM from pin No. 15.
When the EEPROM writes the data, EEPROM outputs the busy signal form DO terminal to CPU.
After finish writing, EEPROM outputs the ready signal from DO terminal to CPU.

10. PROGRAMMING THE CE-3700 SERIES CASH REGISTERS

The Casio CE-3700 series is capable of a versatile range of features and function that give it the
capability to readily adapt to almost any retail environment. The cash register is programmed at the
factory with the most standard operating features and functions. Your local business requirements,
however, may call for other functions of a totally different keyboard layout.

This section explains the different functions available, as well as the procedures that you can use to
tailor the cash register to specific needs. Programming is simplified through the use of worksheets for
each function, and step-by-step flow charts that walk you through each procedure.

10-1. Setting the proper MODE for programming

• Program Modes and feature

You should perform the procedure shown blow as the first step of programming. Notice that the
flowchart ends with an arrow on the bottom. This indicates that you should continue to the next
programming procedure for the mode you specify.

Assignment of 89 functions to programmable keys to create the
desired keyboard layout
Definition of machine features and key functions that enhance
printing, totalizing, reporting and overall operation
Programming of time, date and unit prices, amounts, rates, etc.

• Recommended programming sequence
Generally, you should perform programming in the following sequence. Note that we recommend you
check what is programmed for each mode before proceeding to the programming operation.

10-2. Using the worksheets
The worksheets included in this manual for Program 3 and Program 1 help to make your

programming simple and accurate. We recommend that you fill out the pertinent worksheet before
attempting actual programming.

1) Carefully read each definition and specify a selection.

Each definition is following by a Specification column which contains numeric values(Usually to

indicate a simple YES or NO answer). Determine the correct value according to your need and

enter it in the Selection column to the right.

2) Total each set of selections to calculate each program code digit.

Three selections(a,b,c) make up a set. Add up each set of selections and fill in the totals in the

Program code column for data items D8 through D1.

3) Program the feature or function.

Be sure that you have filled in all of the selections and program code digits for the entire worksheet,

and follow the procedure noted for the feature or function you are programming.

4) Check the printed program receipt against the worksheet.

Perform program read operation in each program mode to print setting which you have

programmed, to check then against the worksheet. We recommend that you do so and keep a copy

on record to help out should it become necessary for you to change the program.
10-3. Clearing a machine lock up
If you make a mistake in operation, the cash register may lock up to avoid damage to programs and

preset data. Should this happen, you can use the following procedure to clear the lock-up without
losing any memory data.

11. OPERATION

Operation of your cash register is designed to be simple enough to master without any special techni­cal knowledge. Anytime you make a mistake in operation, an error tone sounds and further operation
becomes impossible to protect your valuable data. Whenever this happens, you can resume normal
operation after pressing the “C” key.

Printing of the symbol “—” can be programmed when the “C” key is operated in the REG1, REG2, and
RF modes. The number of the “C” key operations can also be programmed for printing on the general
control Read/Reset reports.

As you become familiar with the key layout of the cash register, you may find that your keyboard
entries are getting ahead of the receipt and journal printer. But you never need to worry that the cash
register will miss anything. A built-in key input buffer memory holds entries for up to eight keys to let
the cash register catch up when you slow down or stop.

Another thing you don’t need to worry about is power outages. Your register features built-in recharge­able lithium batteries that return such information as program data, registration records, data, item, and
consecutive number.

These and other features and functions of the CE-3700 series electronic cash register make it a
welcome addition to any retail environment.

• Performing daily cash register operations
