∗
The signals which are hatched are added or revised to or from AL-1000.
(3) Expanded PWB interface section
The MCU PWB and the expanded PWB are connected by CN5 connector to make serial communication (UART).
The FAX PWB uses signals in Table A, and the PCL PWB uses signals in Table B.
Recognition of FAX PWB or PCL PWB:
If /FREADY is LOW, the FAX PWB expansion is recognized.
If /PREADY is LOW, the PCL PWB expansion is recognized.
