Communications
Transparent (Auxiliary Port Mode)
Usage:
A common application, in conjunction with handheld readers, is one that
employs an auxiliary readout to detect mis-applied symbols.
Definition:
In
Transparent
mode data is passed between the auxiliary port and the
host. The reader buffers data from the auxiliary port and echoes the keyed
data on the auxiliary port.
• Auxiliary port data is passed through to the host
whenever a return key is pressed at the auxiliary
port or whenever symbol data is sent. If sent with
symbol data, it is processed on a first-in/first-out
basis.
• Auxiliary port data to the host is always sent with
a preamble and a postamble.
• If the reader is in a polled mode to the host, auxiliary
port data will still pass through.
•
<D>
is the only command accepted by the reader from the auxiliary port.
All other commands will pass through to the host.
Data initiated from the Verifier
• Transmission to the auxiliary port occurs immediately
upon a good read.
• Data sent to the auxiliary port does not include a
preamble or a postamble.
• Communications with the auxiliary port is always
in Point-to-Point protocol, even if the host is in a
polled protocol mode.
Data initiated from the Host
• All host data is echoed to the auxiliary port in
unpolled mode.
