3.1.6
Device Display for Dynamic IP Address Mode
For a device instance configured in the Dynamic IP Address Mode,
Dynamic IP Configuration
, will
be displayed above the current encoder selection, indicates that the IP Address or Printer Name
must be supplied at the time that the encoder session is established.
When in the Dynamic IP Address Mode, the associated Printer Serial Number is not available and it
is not embedded within the Encoder Device Name String. As shown above, the serial number
component of the Encoder Device Name String is simply replaced by the
Encoder
text label. In the
Dynamic IP Address Mode, the Instance Enumeration Index value is appended to the end of the
Encoder Device Name String as in the previous two modes.
When using the Dynamic IP Address Mode, it may be desirable to install multiple OMNIKEY 5121
Ethernet Encoder device instances on a single server or workstation, with each device instance
configured in this mode. Doing so will enable simultaneous access to multiple OMNIKEY 5121
Ethernet Encoder devices and each device will be independently addressed at the time its encoder
session is established (via IP Address or Printer Name). In this scenario each individual OMNIKEY
5121 Ethernet Encoder device instance will be identifiable by its unique Instance Enumeration Index
value.
3.1.7
Failure to Establish a Temporary Encoder Session
If the newly installed encoder instance has been configured in Fixed IP Address Mode or Fixed
Printer Name Mode then the OMNIKEY 5121 Ethernet Encoder Utility will attempt to establish a
temporary session with the encoder device to retrieve its device configuration information.
If the attempt to establish this temporary session fails, then the device configuration process will
be terminated and an error message dialog similar to the following will be displayed.
After the error message dialog is dismissed control will return to the main window of the
OMNIKEY 5121 Ethernet Encoder Utility. The new encoder device instance will still be displayed in
the Encoder Selection drop-down list.
