• ON PORTIN.STARTPRINT GOSUB nnn
PORTIN
This command is a version of the PORTIN(PORT) command and checks the
current state of a specified signal. This command returns -1 if the signal is
asserted, or 0 if the signal is de-asserted.
Note: This command is supported by Fingerprint and Direct Protocol.
Examples:
• PORTIN.STARTPRINT
or
• PORTIN.RIBBONLOW
PORTOUT
Supports manually modifying the dataready signal. PORTOUT is not allowed
when the applicator port style is set to S-Style.
Note: This command is not supported by Direct Protocol.
Example
• PORTOUT.DATAREADY ON
• PORTOUT DATAREADY OFF
where on asserts the dataready signal low and off de-asserts the dataready
signal high.
ON PORTOUT
This command allows a Fingerprint application to detect when out signals have
been reset to default values. The command moves to a specified subroutine
whenever the applicator port status is enabled, and whenever the applicator
port style is changed.
Example:
• ON PORTOUT.RESET GOSUB nnn
Using External Applicator Signals
The printer responds to external applicator port signals differently, depending
on whether your application is using Fingerprint or Honeywell Direct Protocol.
Fingerprint and Applicator Signals
When you use Fingerprint, all in signals and the Data-ready out signal are
handled by Fingerprint. Other out signals are handled by firmware.
