  • Page 7: Introduction

    Overview This document describes the Printronix General Purpose Input/Output (GPIO) function available for the Printronix T5000 series Thermal printers and the P5000 series Line Matrix printers. GPIO is both hardware and software. The hardware is the I/O board to be mounted in the printer the Printronix Remote Management Software Advanced Tool Kit.
  • Page 8 SPDT relays are used as isolated outputs. Each of these outputs can be activated as an action in response to some event. The board is connected into the printing system through the printer’s expansion port. None of the inputs or outputs is connected to any voltage source; it is the user’s responsibility to make those connections.

  • Page 23: Entry Control Buttons

    This action transmits a report to either the host computer through a selected interface or to the printer front panel LCD. For the LCD the user can select the upper or lower display line and the time the message will be visible.

  • Page 24: Multiple Actions

    Chapter Entry Control Buttons Multiple Actions If required, GPIO can execute a number of actions on a single event. Multiple actions specified for a single event will be executed in the order they are entered in the mapping table. Figure 18 shows a mapping table where the first action is to enable GPIO events by making the Input Opto-coupler event active.

  • Page 25: The On Flag

    The ON Flag The ON Flag You can use the On flag to temporarily disable entries in the GPIO mapping table. This is useful if an extensive mapping table is generated with many events leading to the same action. The On flag allows you to test each event reaction separately without confusion.

  • Page 26: Data Fields

    For example, if the data field contains a label count of 10,000 and that after printing 1,200 forms the printer is turned off due to error, with Non Volatile selected, the printer prints another 8,800 forms when the printer goes online again.

  • Page 27: Data Field Events And Actions

    An example is provided to better understand how Data Field Actions work in correlation to Data Field Events. For this example, we have a printer with a forms count defined in a data field in which after each form prints, the count is updated to reflect the correct number of forms still to be printed.
  • Page 28 Chapter Data Fields To decrement the label count by one each time a form prints, specify this event to happen in the Data Field parameter block when a label printing occurs. Operator Data Field Settings are defined in Table 3. Operator D = S D = D + S...

  • Page 29: Data Field Events

    Data Field Events To have a message sent to the front panel display when the printer count reaches zero, we need to keep track of the forms count. For this we use the Data Field Changed event. Each time the data field changes, a specific event generates.
  • Page 30 Chapter Data Fields The Source drop down menu is the data field for which the event is active. The Value field allows you to specify the number you want the Source to be compared. The Condition field indicates when exactly the related action takes place.

  • Page 31: Defining Reports

    Defining Reports Reports are messages that can be sent to a number of destinations in the printer. A report is created by specifying one or more sections and by indicating the sequence in which these sections should be combined to form the report.
  • Page 32 2. Click the Sections tab (Figure 30). We will use this tab to define all sections needed to make the full report. The printer front panel LCD is has a maximum of 16 characters available per line to display the message.

  • Page 33: Sections
