Figure 186. Power-Up Settings – GPIO Control Tab
Within the Power-Up Settings tab are two tabs, GPIO Control and IO.
NOTE: Settings made GPIO Control and IO predefining the output levels of
GPIO will only be functional when the advanced GPIO features are
enabled in the printer.
The GPIO Control tab allows the specification of the GPIO power-on
configuration. This can be either the printer configuration or a predefined one.
If “Use Printer Configuration” is selected, initial GPIO settings will be as
specified in the Printer Power-On Configuration. See Figure 186.
If “Use Predefined” is selected, you can specify the following options:
• GPIO – Enable or disable the GPIO at power-on.
• GPIO Monitor – Switches the GPIO monitor on or off. The GPIO monitor
is the reflection of the opto-coupler inputs in the lower line of the LCD.
• Power-Up Table – specifies the mapping table to use following power-on.
• UCP – Universal Control Port is an offline available TCP port. To enable
the UCP port, check mark the Enable option.
NOTE: Enabling the UCP port disables the PXML port.
• Enable PAA Control – When enabled, PAA control matches from the
active CST table is reported to GPIO by the Data Field Changed event.
The predefined data field PAA State is used to generate the event. GPIO
can check this data field for changes. See “Data Field Events” on
page 245. PAA delays further data processing until GPIO acknowledges
the event. GPIO acknowledges the event by setting the PAA State field to
either NACK or ACK. When GPIO replies with NACK, PAA ignores the
match and sends the data to the emulation it is bound to. When GPIO
replies with ACK, PAA executes the match as defined in the CST.
