4. CIRCUIT EXPLANATION
4-1. Power supply circuit
The power supply circuit provides the following voltage for the main circuit.
Output Pin No1-----VC1 (DC32.3V):To the VC line for the VFD Display power. (Not used for CE-6000)
Output Pin No.2----VC2 (DC24V):To the Vp line for the printer power.
Output Pin No.3----VLED (DC5.85V): To the Vcc,Vcc2 and Vdd for the logic circuit power.
Output Pin No.4----GND:Signal GND.
The power switch SW1 is located at the right side of the lowercase.
After connected the power plug into AC outlet and turn on the SW1, the transformer T1 will genarate the
about AC33V to secondary side. Then, after rectifier circut, the VC1 (DC32.3V) is supplied to the VC line
for display power (for the drive of display tube. Not for LED model.)
The IC2 is the shunt regulator for the control of Q1 transistor. This circuit is genarate the VC2 (DC24V)
for the printer power. The IC1 is regulator for 5V power supply.

Test procedure
1) Operate the send machine first. The send machine will wait the "C" signal (send request) reception
from the reception machine.
The send machine will wait the send request signal about 30 seconds. When it is over 30 seconds,
the time out error will be printed on the receipt.
2) Operate the reception machine. Then, the both machines are communicated each others. This time
first block data wait time is 5 seconds. The total resend request time is 5 time.
3) During communication waiting time, the display will show the "-" brinking on the most left side digit of
segment display. When the data is OK, the reception/transmission packet number will be displayed
on the segment display.
NOTE1: To stop this opeartion, press any or trun off the mode key switch.
NOTE2: The send packet data format is as follows:

ADDRESS INPUTS: Inputs for addresses during read and write operations.
Addresses are internally latched during a write cycle.
DATA INPUT/OUTPUTS: Inputs data and commands during CUI write cycles;
outputs data during memory array. status register, and identifier code read
cycles. Data pins float to high-impedance when the chip is deselected or
outputs are disabled. Data is internally latched during a write cycle.
CHIP ENABLE: Activates the device's control logic, input buffers, decoders,
and sense amplifiers. CE#-high deselects the device and reduces power
consumption to standby levels.
RESET/DEEP POWER-DOWN: Puts the device in deep power-down mode
and resets internal automation. RP#-high enabies normal operation. When
driven low. RP# inhibits write operations which provides data protection during
power transitions. Exit from deep power-down sets the device to read array
mode. RP# at VHH enables setting of the master lock-bit and enables
configuration of block lock-bits when the master lock-bit is set. RP# = VHH
overrides block lock-bits theredy enabling block erase and byte write
operations to locked memory blocks. Block erase, byte write. or lock-bit
configuration with VHH<RP#<VHH produce spurious results and should not be
attempted.
OUTPUT ENABLE: Gates the device's output during a read cycle.OE#INPUT
WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and
data are latched on the rising edge of the WE# pulse.
READY/BUSY#: Indicates the status of the internal WSM. When low, the
WSM is performing an internal operation (block erase, byte write, or lock-bit
configuration). RY/BY#-high indicates that the WSM is ready for new
commands, block erase is suspended, and byte write is inactive, byte write is
suspended, or the device is in deep power-down mode. RY/BY# is always
active and does not float when the chip is deselected or data outputs are
disabled.
BLOCK ERASE, BYTE WRITE, LOCK-BIT CONFIGURATION POWER
SUPPLY:For erasing array blocks, writing bytes, or configuring lock-bits. With
VPP ≤ V
, memory contents cannot be altered, Block erase, byte write, and
PPLK
lock-bit configuration with an invalid VPP (see DC Characteristics) produce
spurious results and should not be attempted.
DEVICE POWER SUPPLY:Internal detection configures the device for 2.7 V,
3.3 V or 5 V operation. To switch from one voltage to another, ramp V
CC
down
to GND and then ramp VCC to the new voltage. Do not float any power pins.
With VCC ≤ V
operations at invalid V
, all write attempts to the flash memory are inhibited. Device
LKO
voltage (see DC Characteristics) produce spurious
CC
results and should not be attempted. Block erase, byte write and lock-bit
configuration operations with VCC < 3.0 V are not supported.
GROUND: Do not float any ground pins.GNDSUPPLY
NO CONNECT: Lead is not internal connected: it may be driven or floated.NC
