Transparent Mode
Usage:
Often used in conjunction with handheld readers. Employs an auxiliary
readout to detect mis-applied bar code 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. I
Data initiated from the Auxiliary Port
• Auxiliary port data is passed through to the host whenever a return
key is pressed at the auxiliary port or symbol data is sent.
• Whenever aux port data is sent with symbol
data, the aux port data will appear between the
preamble and the symbol data.
• 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.
Data initiated from the Reader
• Transmission to the auxiliary port occurs imme-
diately upon a good read.
• Scan data 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 and polled mode.
