M-S Output Parameter
Configurations
Parameter 26 - [M-S Output] has the following five configurable bits.
Figure E.2 Parameter 26 - [M-S Output] Bits and Corresponding I/O
When you enable Cmd/Ref or Datalink in the adapter, you must set the
corresponding bit in Parameter 26 - [M-S Output] if you want the output
data to be sent to the scanner or master device.
Table E.C
and Table E.D list possible configurations for Parameter 26 -
[M-S Output] and the possible data size allocation associated with each
value depending on the method of data transfer.
