Serial Parameters
The PT40 is pre-configured at the factory with the parameter settings for serial
communications found in
Ta bl e E - 7.
Table E-7. Default Parameter Settings for Serial Communications
Ta bl e E - 8 specifies serial parameters. Refer to Serial Parameters starting on
page D-12 for bar codes to set serial parameters.
Table E-5 on page E-8 includes Code 39 and ASCII equivalents for serial char-
acters. Use the Code 39 equivalents when creating bar codes for programming.
For a complete listing of parameters and defaults, refer to
Programming Param-
eters on page E-1.

ID # Parameter Description
C1 Baud rate
Determines the communication speed. The setting for the
PT40 must match the setting that the host computer uses.
C2 Data bits Specifies the number of data bits in each character.
C3 Parity Specifies the parity of the data characters.
C4 Stop bits Selects the minimum space between data characters.
C5
Xon/Xoff hand-
shaking
Used for software data-flow control. With this option enabled,
the PT40 transmits an Xoff character when its serial input
buffer has fewer than ten characters of free space. Once all the
data in the serial buffer is processed, the PT40 transmits an
Xon character.
