Data Bit 8
•
Enable (factory default). Allows access to the extended ASCII character set.
•
Disable. The printer interprets bit 8 of each incoming data character as a zero, regardless of its
actual setting.
PI Ignored
The PI (Paper Instruction) signal is used to control vertical paper motion.
•
Enable (factory default). Ignores the PI signal and treats the data as characters or control codes.
•
Disable. Causes the printer to interpret the eight data lines as VFU commands when the PI signal is
true.
Data Polarity
The Data Polarity parameter must be set to match the data polarity of your host computer.
•
Standard (factory default). 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 vice versa.
Resp. Polarity
The Resp. Polarity parameter must be set to match the response polarity of your host computer.
•
Standard (factory default). Does not invert the response signal.
•
Inverted. Inverts the response signal sent to the host computer.
