Useful when the user wants symbol data
displayed on an auxiliary menu close to the Imager.
Definition:
In Half Duplex Mode all auxiliary port data and symbol
data is sent directly to the host. Symbol data is displayed on the
auxiliary port menu at the same time the data is sent to the
host.
Data Originating from the Auxiliary Port
Auxiliary port data to the host is ignored if the Imager is in
a polled mode.
Auxiliary port data or read data is sent to the host whenever
it is received.
Auxiliary port data is not echoed.
Auxiliary port data to the host is always sent without a
preamble or postamble.
Data Originating from the Imager
Data is transmitted to the auxiliary port at the same time it
is transmitted to the host.
Data transmission conforms with all parameters specified in the
configuration menu (e.g. Preamble, Postamble, End of Read
Cycle).
Data Originating from the Host
All host data is echoed to the auxiliary port in unpolled
mode.
