112Chapter 4 Config MenuData PolarityThe Data Polarity parameter must be set to match the data polarity of yourhost computer.• Standard (default). Does not expect the host computer to invert the data.• Inverted. Expects the data received on the data lines from the hostcomputer to be inverted. Ones become zeros, and vice versa.Resp. PolarityThe Resp. Polarity parameter must be set to match the response polarity ofyour host computer.• Standard (default). Does not invert the response signal.• Inverted. Inverts the response signal sent to the host computer.Busy On Strobe• Enable (default). Asserts a busy signal after each character is received.• Disable. Asserts a busy signal only when the print buffers are full.Latch Data OnSpecifies whether the data is read on the leading or trailing edge of the datastrobe signal. The default is leading.Prime Signal• Enable (default). The parallel port will perform a warm start (reboot) if thehost asserts the prime signal.• Disable. The parallel port will not perform a warm start (reboot) if the hostasserts the prime signal.TOF Action• Reset (default). A form feed is performed before a warm start when theprime signal is asserted from the host. This setting is used only if theprime signal parameter is enabled.• Do Nothing. Nothing occurs before a warm start when the prime signal isasserted from the host.Buffer Size in KConfigures the amount of memory allocated for the Centronics parallel portbuffer. You can specify between 1 and 16 Kbytes, in 1-Kbyte increments.The default is 16K.
