Access Description
If enabled, master must
acknowledge it is ready for
Get/Set next new data before 1734-
232ASC module sends the
new data.
Total number of bytes of I/O
data that are sent to the
master from the 1734-
Get
232ASC module. This
should be the RX size of
your scanner.
Serial data in the receive
Get
buffer
Number of characters in
Get
the receive data buffer
The receive record number
Get/Set
sent from the master
Maximum number of
characters the 1734-
Get/Set 232ASC module expects to
transmit out its serial port
to the serial device
Selects whether the End
Get/Set delimiter is included with
the received data
Character that identifies
the end of the transmit
Get/Set data string from Ethernet to
the ASCII device when the
length is specified as 0
Defines the format of the
Get/Set data string that is received
from the master
If enabled, the position of
the bytes in the serial
Get/Set
messages is swapped
every 2 bytes or 4 bytes
Selects the source of the
event that triggers the
Get/Set
transmission of data over
the serial link
Total number of bytes of I/O
data that are received from
Get
the master. This should be
the TX size of your scanner.
Serial data to be sent to the
Get/Set
serial transmit buffer
Length of the transmit
Get/Set
serial data
The transmit record
Get/Set number of the current
transmit data buffer
The combined status byte
for the serial port object,
Get the receive record object
and the transmit record
object.
