3.1 MAIN PC BOARD
3. CIRCUIT DESCRIPTION EO6-11056
3.1 MAIN PC Board
This circuit is used to control the receipt printer, journal printer, etc.
The receipt printer is connected to CN4, and the journal printer is connected to CN5.
IC20 and IC21 are Buffer ICs which buffer the various control signals and the print data output to the
receipt printer and the journal printer.
The P-DATA signal which synchronizes the P-CLK signal is output to the printer. The /P-LAT signal
latches the print data.
The /P-STB1, /P-STB3, /P-STB4 and /P-STB5 are strobe signals. When the signal is on, the printing
operation is performed.
The /PRJSEL, PRJSEL, and /STB-ON signals are enable signals for IC20 and IC21.
When the /PRJSEL and /STB-ON signals are at a low level, the buffer on the receipt printer side
becomes active.
When the PRJSEL and /STB-ON signals are at a low level, the buffer on the journal printer side
becomes active.
IC1 and IC2 are driver ICs for the stepping motor.
IC1 controls the stepping motor in the receipt printer and IC2 controls that in the journal printer.
The MT-A, MT-/A, MT-B, and MT-/B signals which are output from the driver ICs will be the pulse
signals for the receipt printer and the journal printer.
The DC motor which takes up the journal paper is connected to CN3. The MOT-ON signal which is
output from the CPU performs an on-off control of the DC motor. When this signal is at a high level,
the DC motor works.

RS-232C interface connector and its driver IC
PK-2 keyboard connector
Real time clock
LCD connector and brightness adjustment volume connector
Buffer for data transmission from various peripheral devices
The PK-2 keyboard is connected to CN11.
When the /PK2CS signal output from the CPU is at a low level, the PK-RXD, PK-CLK, and /PK-INT
signals output from the PK-2 keyboard are input to the CPU via IC7 (buffer IC).
The /PK-INT signal is an interrupt signal to the CPU. When receiving an interrupt request, the CPU
outputs the /PK2CS signal then inputs the serial data of the PK-RXD signal in synchronization with the
PK-CLK signal.
IC8 is a real time clock which controls date and time. The 32.768-KHz clock signal generated from X1
is used as standard.
When the /RTCS signal output from the CPU is at a low level, IC4 will be enabled. The serial data of
the RT-TXD signal is input to IC8 in synchronization with the RT-CLK signal.
CN1 which is embedded with the CPU is an RS-232C serial interface connector.
IC3 is a driver IC for this serial interface, which sends the S1-TXD and S1-RXD signals between the
CPU and the RS-232C interface.
The 192 x 64-dot LCD display is connected to CN9.
The LCD brightness adjustment volume is connected to CN8.
The LCD display is controlled by the CPU data bus D0 to D7. The data bus D0 to D7 is used to
generate the display data, chip select signals CS1 to CS3, etc.
