4-3-4 I/F PBA Detect Block Diagram
When the printer is ON, the printer checks what kind of the I/F PBA is installed. After detection, the CPU
specify the I/O port properly. The following is the method of I/F PBA detection.
First, the CPU sends a “I/F Sel” signal (P7.0) to I/F PBA. The I/F PBA has the three return Signal (DIP 1~3).
The CPU recognize the I/F PBA by the value of the three return signal.
