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 display-
ed on the LCD. 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 wit-
hout parity bits.
