Interfaces Serial interface (option)
B-13
Data rates
The interface supports the following data rates.
• 4800 bps
• 9600 bps
• 19200 bps
• 38400 bps
Supported protocols
This interface will also support the following:
• 7 or 8 Data Bits
• Even, Odd, None Parity
• 1 or 2 Stop Bit(s)
• Ready/Busy or XON/XOFF handshaking
Data Transfer
A data frame consists of a start bit, seven or eight data bits, 0 or 1 parity bit(s) and 1 or
2 stop bit(s). With these combinations, 9, 10, 11 and 12 bit frames are available:
Parity
There are three possible parity settings: Even, Odd, None.
} When Even parity is specified, the interface expects to receive data frames with even
parity and will transmit data with even parity.
} When Odd parity is specified, the interface expects to receive data frames with odd
parity and will transmit data with odd parity.
} Parity will be checked whenever Even of Odd parity is selected. When a parity error
is detected, printer will indicate warning status on the lights. Printer will continue to
receive data.
} When None parity is specified, the interface does not accept data frames to include a
parity bit, and the interface transmits data without parity bits.
