Input Function - Hitachi IJ RX2 Technical Manual

4.3.3 Input function

The IJ printer can be controlled by inputting print stop, remote operation ("Startup", "Shutdown", "Reset",
"Deflection voltage control") and reciprocative print switching to pins 4, 5, and 14 to 18 of TB1 by switch or
contact signal from the outside.
