5-8 OPE PBA
5-8-1 SUMMARY (WorkCentre Pro 412 & FaxCentre F12)
OPE Board is separated functionally from the main board and operated by the micom(Z8601) in the board.
OPE and the main use UART (universal asynchronous receiver/transmitter) channel to
exchange information. OPE reset can be controlled by the main. OPE micom controls key-scanning and
LCD and LED display. If there occurs an event in OPE (such as key touch), it sends specific codes to the
main to respond to the situation and the main analyzes these codes and operates the system. For exam-
ple, it the main is to display messages in OPE, the main transmits data through UART line to OPE accord-
ing to the
designated format and OPE displays this on LCD, LED. OPE’s sensing is also transmitted to the main
through UART line and then the main drives necessary operation.
OPE PBA consists of U1(MICOM, Z8601),LCD, key matrix, LED indicators. Refer to OPE Schematic
Diagram and Wiring Diagram sections of this manual.
•
Signals from the key matrix are delivered to U1 input pin group (D1 to D6)
•
U1 pin 48 (TX DATA) is the UART code sent to MAIN PBA.
•
Display from the controller is received at U1 pin 5(RX DATA).
•
LCD drive signals are sent from U1 P2-x pin group, P3-4 to P3-6 pins.
•
Machine status LED drive signals are sent from U1 LED1 to LED8.
