Interfaces 7-2
Ready Line - A high true level from the printer indicating ac power and dc voltages are preĆ
sent, paper is loaded properly, and the printer is not in a check condition.
On Line - A high true level from the printer indicating the Ready Line is true and the ON
LINE switch on the control panel has been activated.
Data Request - A high true level from the printer to synchronize host data transmission with
printer timing.
Data Strobe - A high true pulse from the host to indicate that data is ready. The data strobe
remains high until the Data Request line goes false.
Data Lines - Eight high or low levels from the host that specify character data, plot data, or a
control code. Sensing Data Line 8 is controlled by printer configuration.
+5 Volt Test - +5 Vdc output for operating the Printronix test exerciser.
Paper Instruction (PI) - Optional high true level EVFU signal from the host with the same
timing as the data lines. Sensing the PI line is controlled by printer configuration.
Interface Verification - Two pins on the interface connector jumpered together to allow the
user to verify proper installation of the interface connector.
