OPE (05W) Circuit Diagram
1.
Block diagram
Figure A3.2.1 shows a block diagram of OPE (05W).
The O5WH (operation unit) circuit consists of the following blocks:
1)
IC1 (one chip MOS-CPU)
•
Output ports
Setting LEDs on and off: 8 ports
Specifies the row during key switch matrix scanning: 8 ports
•
Input ports
Detect the column whose key is pressed: 8 ports
2)
Key switch matrix (8 rows x 8 columns)
3)
LEDs (8 LEDs)
4)
LCD unit
2.
Key switch scanning
Output ports (KSCAN0 to KSCAN7 signal) corresponding to 8 rows of key matrix are
scanned sequentially by the software. In the case 1 is any of output from KSCAN0 to
KSCAN7 signal which corresponds to the row 8 in the block diagram, the software reads
input port, KSENS0 to KSENS7, and determines which in the row 8 is pressed.
3.
LED drives and LEDs
Eight LEDs (ALARM, PHOTO, LIGHT, etc.) on the control panel are driven by output of
IC1 via resistors R1, R4-9 and R11 respectively. An LED lights on when a port output is
1.
4.
In case sub-power supply is applied to the fax machine: when PC1-N, HUP-N or RIINT
signal is input to OPE unit, OPE unit controls the main power supply (120/230 board) by
outputting the MP/OFF (ACON) signal.
•
PC1-N:
Presence of document on hopper
•
HUP-N:
OFF-Hook detection for TEL 1 and TEL 2 terminal
•
RIINT:
Ringing detection signal
