READY/BUSY INTERFACE SIGNALS

DB-9	14 PIN	DIRECTION	SIGNAL DEFINITION
PIN	CENTRONICS
			When Mode1 on the LCD is selected High Voltage = Online Print Job
	9	To Host	Waiting.
			When Mode2 on the LCD is selected High Voltage = Online. This goes
			low (0V) when the printer is offline.
	11		Reserved.
	12	To Host	+24V +/- 10% @2A - Power for external devices.
	14		Frame Ground

NOTE: The signals on pins 1, 3, 4, and 10 each have an open collector output. These pins normally measure +.07V maximum when a true condition exists. If a false condition occurs, the voltage will drop to 0V. To achieve a signal level of +5V, a 330 ohm, 1/4 watt pull-up resistor between the open collector output pin and Vcc (pin 13) as illustrated. This will provide a signal level of +5V for a true condition and 0V when a false condition exists. The maximum voltage that can be applied to these pins is +50V and the maximum current they can sink is 500 milliamps.
