Applicator Interface Kit Installation Guide 21
Handling Internal System Errors
For internal system errors, the system error signal status can be read at any
time within the application so appropriate measures can be taken. When any of
these errors occur, the appropriate out signal (including the error) is asserted:
• Ribbon low
• Ribbon out
• Media low
• Media out
• RFID tag error
Example
• 10 IF PORTIN.RIBBONLOW GOTO 200
...
200 perform error handling
210 RETURN
Resetting Out Signals
Out signals are reset to their default values when certain options are changed
by using the SETUP menu. When the reset is detected, the application moves to
a specified subroutine and performs the tasks necessary to reinitialize the print
engine.
Example
• 10 ON PORTOUT.RESET GOSUB 150
...
150 perform initialization
160 RETURN
Direct Protocol and Applicator Signals
In Direct Protocol, all in and out signals are handled by the Direct Protocol
firmware.
Feed
There are two ways to trigger blank label feeding:
• by manually pressing Feed on the printer front panel. The printer feeds a
single blank label.
• by using the Feed in signal. When this signal is detected, the printer feeds
blank labels as long as internal applicator flag indicates that the Feed
signal is asserted.
