1) MEMORY BACK UP BATTERY

For memory back up, the dry battery AA (3 pieces) are needed.

1. Memory holding time: Approx. 1 year after New dry batteries are installed.

2. Battery exchange method: When the low battery symbol “L” lights up, replace the batteries (3

AA) by the following method;

1) Power on the ECR.

2) Mode switch turn to “REG” mode.

3) Remove the OLD dry batteries (3 pieces).

4) Insert the NEW dry batteries (3 pieces).

5) Confirm the low battery symbol “L” is off.

2) LOW BATTERY

Low battery indication will appear on the left side of display when the battery voltage is low.

CASE 1: W hen any nume ric entry & any item entry is not done or just

after finalization.

The machine can indicate the low battery condition. (Always)

CASE 2: W hen num eric entry or item entry is done.

Battery condition will not appear. Exceptionally, when the power is restored after a power failure, the low battery condition will appear on the display only when the battery is low. And the indicator will disappear after any key entry.

[Display sample]

“ 0.00”: Battery is OK. “L 0.00”: Low battery (You have to change the batteries.) “

L 0.00”: No battery (You have to change the batteries immediately.)

After finalization

“F 12.34”: Battery is OK. “L 12.34”: Low battery. (“L” indicate instead of “F”.) “

L 12.34”: No battery. (“L” indicate instead of “F”.)

CHAPTER 3. MASTER RESET AND PROGRAM RESET

1. MASTER RESETTING

Master resetting clears the entire memory and resumes initial values. Master resetting can be accomplished by using the following procedure:

Procedure A: 1) Plugin the AC cord to the wall outlet.

2) Set the mode switch to REG position.

3) Let the ECR be witout the memory backup battery.

4) Unplug the AC cord from the wall outlet.

5) Wait over 1 minute for discharging.

6) Plugin the AC cord to the wall outlet.

The master reset can also be accomplished in the following case.

In case power failure occurs when the machine has no battery attached to it, the master reset operation is automatically performed after the power has been restored.

(This is because if power failure occurs with no battery attached to the machine, all the memories are lost and the machine does not work properly after power recovery; this requires the master reset operation.)

2. PROGRAM RESETTING

(INITIALIZATION)

This resetting resumes the initial program without clearing memory. This resetting can be operated at below sequence in PGM mode.

Procedure: 1) Unplug the AC cord from the wall outlet.

2) Wait over 1 muinite for discharging.

3) Set the mode switch to the PGM position.

4) While holding down the FEED key, plugin the AC cord to the wall outlet.

Note: In case power failure occurs when the machine has no battery

attached to it, the master reset operation is automatically performed after the power has been restored.

CPU

XCOUT

Two oscillators are connected to the CPU. The basic clock X2 is supplied from a 12MHz oscillator. If the CPU was not operating properly, the signal does not appear on this line in most cases. The sub-clock X1 generates 32.768KHz which is primarily used to update the internal RTC (real time clock). During the standby mode, it keeps oscillating to update the clock and monitoring the power recovery.

P-OFF

The P-OFF signal detects two signals by two comparators and sent to the CPU.

V0 (24V) signal: If the power voltage V0 (24V) falls bellow the specified

2) Print circuit

Thermal head configuration

As shown in the equivalent circuit in the figure, thermal head consists of heating elements and head drivers which drives and controls those heating elements.

The serial print data input through the DATA IN (D1) is transferred to the shift register synchronizing with the CLOCK (CP) and stored in the latch register by the LATCH (LA) signal.

The head conduction signals (print commands 1 ~ 6) turn the gate on to conduct the heating element corresponding to the print data.

CHAPTER 6. IPL (Initial Program Loading) FUNCTION

The application program of the XE-A202 is written into the Flash ROM in the CPU.

Since the CPU supplied as a service part does not include the application program in it, the application program must be written when the CPU is replaced with a new one.

To write the application program into the Flash ROM, connect the PC and the XE-A202 with an RS-232C cable, and execute the PC software.

*Use a D-Sub 9pin cross cable employed in conventional communica-

tion between ECR-ECR (See APPENDIX: RS232C CABLE).

1) Connect the XE-A202 and PC with an RS-232C cable.

<XE-A202 side>

2) Turn off the AC Power. (& remove batteries.)

3) Open the cabinet.

4) Change the IPL JUMPER PIN (SP1) to the rear side.

7) Copy the following files in "PosUtilityTool3" into the hard disk of PC. Postool3.exe A202u.ROM

8) Boot "Postool3.exe."

9) Push [Add Files] in the screen.

10) Select the ROM DATA file. (File name: A202u.ROM)

11) By pushing [Send] in the screen, the ROM data is sent from PC to

ECR. The address counter is shown on PC and counts up.

12) After about 3-minuites, the message "Complete" is shown on PC.
