DESCRIPTION

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) Unplug the AC cord from the wall outlet.

2) Set the mode switch to the PGM position.

3) While holding down both the JOURNAL FEED key and [CL] key, 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) Set the mode switch to the PGM position.

3) While holding down both JOURNAL FEED key and

RECEIPT 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.

The A401 has an LCD display, 5 x 7 dots, 2 lines, at the front side and a

7-digit LED at the pop-up side.

FRONT:

7. REWRITING FLASH MEMORY

IPL from EP-ROM: After IPL SW is set to ONA the program is started from EP-ROM by turning on the power.

The program on EP-ROM is transferred to flash

ROM by switching the banks through S-RAM.

IPL from COM:

Data from the PC is written to flash ROM through the COM port. (Max. 38.4 kbps)

POP UP:

• Display DIGIT signal

The above ST0 ~ ST6 are display digit signals.

ST0: 1st digit ~ ST6: 7th digit

• Display SEGMENT signal

The LED segment signal is outputted by writing SEGMENT data in the /CS3 space.

Correspondence of DATA ~ SEGMENT

8. DRAWER

The A401 has a 1 channel of drawer port. (+ 1 channel is reserved for the CPU PORT) O R No open sensor is provided.

The driving time for the DRAWER solenoid are as follows: 50ms (max)

45ms (min)

12. RESET

The RESET signal is generated when:

1) The mode key switch is turned from SRV to a position other than

SRV’(excluding OFF).

2) The power is turned ON more than 10 seconds after the power is turned OFF. (The reset signal may not be issued if the POWER-

OFF time is short.)

3) The mode key switch is turned from OFF to a position other than

OF (excluding the SRV position). (If the power-off time is less than 5 seconds, the reset signal may not be issued.)
