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.
If a parity error is detected, “PARITY ERROR” message will be dis-
played on the LCD. Printer will continue to receive data.
` When “No” parity is specified, the interface does not except data
frames to include a parity bit, and the interface transmits data with-
out parity bits.
