1. Block diagram
The circuit diagram shown on page 15/17 consists of the following connector:
•
Connector CN13 that provides an interface between M17 board and optional memory board.
• Connector CN12 and CN17 that provides an interface between M17 board and CTR (PC
interface) board.
Figure A3.2.20 shows the interface between M17 and memory board.
Figure A3.2.21 shows the interface between M17 and PC interface board.
Note 1: One of 1 Mbyte or 2 Mbyte memory board can be added to the memory capacity for
OKIFAX 5500/5600.
1M byte for OKIFAX 5200/5300.
