Data Polarity
The Data Polarity parameter must be set to match the data polarity of
your host computer.
•
Standard. Does not expect the host computer to invert the data.
•
Inverted. Expects the data received on the data lines from the host
computer to be inverted. Ones become zeros, and zeros become
ones.
Response Polarity
The Response Polarity parameter must be set to match the response
polarity of your host computer.
•
Standard. Does not invert the response signal.
•
Inverted. Inverts the response signal sent to the host computer.
Latch Data On
Specifies whether the data is read on the leading, middle, or trailing
edge of the data strobe signal.
Prime Signal
•
Enable. The parallel port will perform a warm start (reboot) if the
host asserts the Prime Signal.
•
Disable. The parallel port will not perform a warm start (reboot) if
the host asserts the Prime Signal.
TOF Action
•
Reset. A form feed is performed before a warm start when the
prime signal is asserted from the host. This setting is used only if
the Prime Signal parameter is enabled.
•
Do Nothing. Nothing occurs before a warm start when the prime
signal is asserted from the host.
