8.3 Description of Input/Output Signals

(1)Input/Output Signals

a)Input Signals (To Printer)

*DATA					: 8 bit parallel signal. (Positive logic)
					: A strobe signal for reading in 8 bit data. (Negative logic)
		*STB

*RESET					: A signal which resets the entire printer. (Negative logic. 1 ms or more)
b) Output Signals (From Printer)

*ACK					: This is a pulse signal for requesting 8 bit data, issued at the end of a BUSY signal.
					(Negative logic)
*BUSY					: This signal indicates that your printer is in a BUSY state. New data should be input
					when this signal is "LOW". (Positive logic)

*FAULT					: When your printer is in an alarm state, this signal is "LOW". At this time, all control
					circuits of your printer are interrupted. (Negative logic)
*PE					: When the paper is near its end, this signal is issued. (Positive logic)
					Note: An alarm condition occurs when the timing of the print head movement sensor is abnormal.
c) Power Source
*+5V DC					: The same +5V output as that of the power source which actuates the control circuits.
					This should be less than 30 mA.
*GND					: The common circuit ground.
*FRAME GND					: Equivalent to "case ground".
