Strobe Polarity; Response Polarity - Printronix P9212 Setup Manual

Response Polarity

The Response Polarity parameter can be set to Standard or Inverted. It must
be set to match the Response Polarity of your host computer.
•
Standard: The printer does not invert the response signal.
•
Inverted: The printer inverts the response signal it sends to the host
computer.

Strobe Polarity

The Data Strobe Polarity parameter can be set to Standard or Inverted. It
must be set to match the Data Strobe Polarity of your host computer. When
the host computer sends a data strobe signal to the printer, this enables the
printer to read the data bus.
•
Standard: The printer does not expect the data strobe signal to be
inverted.
•
Inverted: The printer expects the host computer to invert the data strobe
signal.
Latch Data On
The Latch Data On parameter can be set to Leading Edge or Trailing Edge,
and is dependent on your host computer. To latch data means to read the data
bus. This feature determines whether data on the bus will be read at the
leading or the trailing edge of the data strobe.
Leading edge refers to the time at which an electronic signal changes from a
"false" to a "true" condition.
Trailing edge refers to the time at which an electronic signal changes from a
"true" to a "false" condition.
