I-Class 119Appendix DGPIO Port DescriptionWith the optional GPIO PCB, the printer can easily be programmed to interfacewith most applicator devices. The GPIO functions are enabled and configuredusing the menu system of the printer (see Section 4.1.4). These parameters arestored in non-volatile memory and saved for subsequent power-ups.When the GPIO is enabled, the printer will not print a label unless the Start ofPrint signal is active. When a label is ready to print and the printer is waiting forthe Start of Print signal the printer will display “WAITING FOR SIGNAL”.GPIO Port ConnectionsThe GPIO Port interface connector (see next page) is a 9-pin Mini-DIN femaletype (e.g., Kycon KMDG-9S-BS) requiring a 9-pin Mini-DIN plug (e.g., KyconKMDA-9P). Each GPIO pin function is detailed in the table below:GPIO Pin FunctionsPin#SignalNameSignalStateSignalDirection* Description1 Vcc +5 VDC Output Printer +5 VDC2 RibbonFaultLow Output Goes low when the printerdetects a ribbon fault.3 PaperFaultLow Output Goes low when the printerdetects a label movement fault.4 PrinterFaultLow Output Goes low when any printer faultis detected.5 Spare Reserved Output N/A6 End of Print Programmable Output Programmable7 Spare Reserved Input N/A8 Start ofPrint SignalLow Input When ready to print a label, theApplicator should set this signallow for at least 50ms or until theEnd of Print signal goes notactive.9 SignalGroundGround N/A N/A*Signal direction is given relative to the printer.
