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. If a parity error is de-
tected, PARITY ERROR message will be displayed 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 without parity bits.
