This is also the section in which to set any change of password you need to limit read/write access. To
limit read access, change the Public (Read) Community entry; to limit write access, change the P rivate
(Write) Community
entry. But be aware: alongside any changes you make here, you will also need to
update your SNMP manager to work with these new passwords.
Programming the Control Device
The task of programming the Control Device can be anything from running a commercial MIB Browser
to running a dedicated application.
See the "Automating a Test Procedure" section for more information about preparing a
dedicated application.
Exporting and uploading the Ultra MIB file
To obtain a copy of the MIB, you need to be driving the Ultra using its web-based user interface. The
MIB file for the Ultra is then available for export to disk from the System page of the Configuration
window. Each version of the Ultra software that is released can be expected to generate a new version
of this file which you need to move over to using in order to access any new features introduced in the
release.
A copy of the MIB file can be exported from the ‘Files’ area of the System page of the Configuration
window. The MIB file is downloaded as OmniTekUltra.mib. The steps to use are given below.
Once you have saved the MIB file on disk, you need to do whatever is needed to upload this file to the
SNMP Manager you are using.
Download the MIB file by selecting the symbol next to SNMP MIB
in the Files area to the right of the System page.
The file is downloaded to the Downloads directory associated with
the web browser you are using.
Omnitek OID’s
The best way to discover about the OIDs used by the Omnitek Ultra, their meanings and their possible
values is to load a copy of the MIB file into a ‘MIB Browser’ such as that provided by iReasoning. Even
the ‘free’ version of their MIB Browser provides sufficient information for you to readily determine the
OIDs and values you need to give to your SNMP Manager.
Once the MIB file has been uploaded (using the Load MIBs function in the File menu), the private/
enterprises section of the MIB tree will include an entry for omnitek/ultra , under which will be a list of
the categories into which the MIB file divides the OIDs associated with the Ultra. For most purposes,
the sections of interest will be:
viewer which is concerned with the tiles displayed in the Viewer window
connections
which contains details of the current input and output connections
timing which is concerned with timing of the input relative to the different signals
available as references
videoStatus which accesses values contributing to the Status and Gamut Meters displays
eyeJitter
which accesses a range of Eye and Jitter parameters
presets which is concerned the various presets that have been defined
pictureCage
which accesses the Cage settings made on the System page of the Configuration
window.
