OF5750/5950 Series January 2001
A3 - 61
A3.8 G3A-PCB
This PCB board is optionally available. Using this board allows the system to be ready for
additional G3 line. This board is connected to the MCNT board through the OKI's original
MUPIS interface.
And this board is connected to the NCU board through the DM2 board.
The block diagram of this board is shown on the next page.
This board is connected to the MCNT board with an 80-pin connector (CN1). One pin of this
connector (RM2) is signal line dedicated to the G3A board, and fourteen pins of this connector
are signal lines shared with the option G4A board, and the remaining 64 pins are signal lines
shared with the optional G4A board and LAN network board. It is connected to the NCU board
through the DM2 board with 30-pin connector (CN2).
Data is transferred to/from the CPU on the MCNT board via the 2KB dual port RAM. When
data is sent, the MCNT board causes an interrupt to the G3A board using a CUREQ-N signal
and writes data into the 2KB dual port RAM.
The G3A board reads the data from the dual port RAM in the DRAM, and sends the data to the
NCU board via the DM2 board.
When data is received, the G3A board causes an interrupt to the MCNT board using an
OPREQ signal and writes data from DRAM into the dual port RAM. The MCNT board reads
data from the dual port RAM, expands the data in the DRAM on the MCNT board, and sends
the data to the LED head via the IOGA5.
