CHAPTER 3. MASTER RESET AND PROGRAM RESET
1. MASTER RESETTING
2. PROGRAM RESETTING (INITIALIZATION)
Master resetting clears the entire memory and resumes initial values.
This resetting resumes the initial program without clearing memory.
Master resetting can be accomplished by using the following procedure:
This resetting can be operated at below sequence in PGM mode.
Procedure A:
Procedure:
1)
Unplug the AC cord from the wall outlet.
1)
Unplug the AC cord from the wall outlet.
2)
Set the mode switch to the PGM position.
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.
3)
While holding down both JOURNAL FEED key and
RECEIPT FEED key, plugin the AC cord to the wall
outlet.
The master reset can also be accomplished in the following case.
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.
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.)

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.
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.
FRONT:
IPL from COM:
Data from the PC is written to flash ROM through
the COM port. (Max. 38.4 kbps)
POP UP:
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.
• Display DIGIT signal
The above ST0 ~ ST6 are display digit signals.
The driving time for the DRAWER solenoid are as follows: 50ms (max)
45ms (min)
ST0: 1st digit ~ ST6: 7th digit
• Display SEGMENT signal
The LED segment signal is outputted by writing SEGMENT data in
the /CS3 space.

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 POWEROFF 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.)
