2.8.4 Parameter assignment data of the printer driver
Introduction
You can use the parameter assignment data of the printer driver to generate the
transmission-specific parameters and the message texts for printout.
Parameter assignment data of the printer driver
With the CP 341: Point-to-Point Communication, Parameter Assignment parameter
assignment interface, you can specify:
● The parameters for the physical layer (layer 1) of the printer driver
● The message texts for printout
● The page layout, character set, and control characters for the message texts
You will find a detailed description of the parameters below.
Baud rate/Character frame
The table below contains descriptions of and specifies ranges of values for the relevant
parameters.
Table 2- 16 Baud rate/Character frame (printer driver)
Parameters Description Range of values Default value
Baud rate Data transmission rate in bit/s
• 300
• 600
• 1200
• 2400
• 4800
• 9600
• 19200
• 38400
• 57600
• 76800
• 115200
9600
Start bit During transmission, a start bit is prefixed to each
character to be sent.
1
(fixed value)
1
Data bits Number of bits to which a character is mapped.
• 7
• 8
8
Stop bits During transmission, the stop bits are appended
to every character to be sent; this signals the end
of a character.
• 1
• 2
1
Parity A sequence of information bits can be extended
to include another bit, the parity bit. The addition
of its value ("0" or "1") brings the value of all the
bits up to a defined status. This improves data
integrity. "No" parity means that no parity bit is
sent. "Any" parity indicates that the CP 341 has
set the send parity to a value of "0".
• None
• Odd
• Even
• Any
