Appendix I — Auxiliary Monitor
An auxiliary monitor, connected to the scanner can:
1. Echo data from the scanner or host.
2. Send data to the host.
3. Access and make changes to the scanner's configuration menus.
The monitor can be configured to operate in one of three modes:
• Transparent
• Non-Buffered Full Duplex
• Non-Buffered Half Duplex
Note: Transparent can be used with all protocols. Full Duplex and Half
Duplex operations can be used with any protocol except polled protocols
(Polling Mode D, Multidrop, User Defined, and User Defined Multidrop).
Transparent Mode
Used to batch data from the monitor to the host. The scanner buffers data
from the monitor and displays the keyed data on the monitor. The scanner
transmits monitor data to the host when a label is scanned or a carriage
return is entered from the monitor.
Data Initiated from the Monitor
• Monitor data is passed through to the
host whenever a return key is pressed at
the monitor or whenever bar code data is
sent. If sent with bar code data, it is pro-
cessed on a first-in/first-out basis.
• Monitor data to the host is always sent
with a preamble and a postamble.
• If the MS-7100/7180 is in a polled mode
to the host, monitor data will still pass
through.
• The <D> and <t> commands are the
only commands accepted by the scan-
ner from the monitor. All other com-
mands will pass through to the host.
