Modify Settings | Global Settings | Messaging | Protocol Index
Use the Protocol Index/Aux Message window to configure Protocol Index parameters.
Protocol Index/Aux Message allows the Host to transmit a string that it has associated to a
pack contained within the tracking area.
It is possible to manage several different Protocol Index/Aux messages (one per available
communication interface), within the same reading phase (for the same pack). If more than
one Index message is received on the same communication interface, only the last one will
be accepted.
These strings will be received by the DS8110/DX8210 Master or SC5000 and included within
its output message according to the following order:
1. Built-In Ethernet User Socket 1
2. Built-In Ethernet User Socket 2
3. Built-In Ethernet User Socket 3
4. Auxiliary Serial Port
5. Main Serial Port
The general output format is: <Header>Index1<Data Packet Separator>...IndexN<Data
Packet Separator>Standard Message<Terminator>
The Index field has the following format: <Index Header>Index Message<Index
Terminator>
NOTE: This parameter is only available for scanners configured as
Standalone or as Master when working in On Line or PackTrack
operating modes.
In On Line mode, the Protocol Index must arrive during the active
reading phase otherwise it will be discarded.

In PackTrack mode:

148
If the Distance from Protocol Index to Trigger Line
parameter = 0, the Protocol Index must arrive during the
active reading phase otherwise it will be discarded.
If the Distance from Protocol Index to Trigger Line
parameter is not = 0, the Protocol Index will arrive at the
specified distance.
