When you enable multiple symbologies, the JANUS 2050 may, on rare
occasions, decode bar code labels in a symbology other than the label’s actual
symbology. Row clicks may also occur, indicating that the label was decoded
as a row in a two-dimensional symbology. To avoid this problem, only enable
the JANUS 2050 to decode the bar code symbologies that you are using. If the
problem does occur, scan the label again. MSI and Plessey configurations are
disabled by default.
Defining Communications Parameters
The communications configuration parameters include the communications
ports, protocols, and the parameters that define the individual protocols. The
communications port designates the port for which you are configuring the
protocol. The communications protocol and its parameters determine how the
JANUS 2050 talks to the device to which it is connected.
You can configure more than one protocol for a port. However, only one
protocol at a time can be active for each port. The JANUS 2050 can
communicate using the following protocols and parameters. Each protocol has
certain parameters that can be set for that protocol.
