communications, the user must have host software that can send and receive
ASCII characters. Red Lion's SFPAX software can be used for configuring the
PAXI (See Ordering Information). For serial hardware and wiring details, refer

parity bit for outgoing data. If no parity is selected with 7 bit word length, an
additional stop bit is used to force the frame size to 10 bits.
