1 Operating Options
The transmitter is controlled using the R&S NetCCU800. The R&S NetCCU800 can be operated in the following ways:
– Local operation via the display and menu keys on the front panel of the R&S
NetCCU800
– Operation via the web browser
– Monitoring and control via SNMP
If the unit is operated via the web browser of a connected PC/client computer, two modes
are possible:
– Remote operation via a directly connected PC (connector on front panel)
– Remote control via a remotely connected network client (connector on rear panel)

Chapter 5 Operating
1.1.2.2 Selecting and Editing Entries
The possibility of changing settings is controlled by a user administration facility with authorization system (see the section "User Administration") and a local/remote concept which is
valid for the entire transmitter.
Local and Remote operating modes
Local means the transmitter can be configured on site. Local access is available via the display on the front panel of the R&S NetCCU800 or by PC via the local Ethernet port.
Remote means the transmitter can be configured offsite. Remote access is available via the
remote port on the transmitt e r.
Since local and remote operation are mutually exclusive, configuration work carried out onsite cannot collide with settings entered remotely. However, it is always possible to view
transmitter settings.
The Local key on the R&S NetCCU800 is used to switch b etween the local and remote operating modes.
Locked and variable settings
Depending on the user rights concerned and the type of access (local or remote access)
some or all processing parameters can be locked. These include restrictions ar ising from
the actual constellation chosen. An appropriate symbol in front of the parameter value
shows whether or not a parameter can be changed at this time.
Symbol Meaning
The present user can change the setting. A change takes effect straight away.
The present user can change the setting. For the change to take effect, a restart
of the R&S NetCCU800
The setting cannot be changed at the present time. Possible reasons:
– The user does not have the necessary rights.
– Access is via the remote port when the R&S NetCCU800 is in local mode.
– Access is local when the R&S NetCCU800 is in remote mode.
Setting is not possible in this constellation.
- none - This parameter value is for a display; it cannot be set.
a)
(and possibly the exciter
b)
) must be carried out.
c)
a) To restart the R&S NetCCU800, run the Restart command in the SW Maintenance context menu.
b) If the parameter identified in this way is a setting for the exciter (Exciter ..... menu path), the exciter must be
restarted and then the R&S NetCCU800. To restart the exciter, run the Reboot Tx command in the Tx Setup
context menü (Exciter menu).
c) The Info command from the context menu gives information on the necessary user rights among other
things.
Examples:
2098.0720.72 - 5.4 - E-2
Chapter 5 Operating
1) Setting can be changed, but the R&S NetCCU800 needs to be restarted
2) Setting can be changed; a change takes effect straight away
1) Due to insufficient user rights, the selected parameter cannot be changed at this time
2) Operation access rights are needed in order to change this setting
Selecting entries
The Edit ... selection window is displayed as soon as you click OK to confirm a field that
provides a choice.

1.4 Monitoring and Control via SNMP
SNMP (Simple Network Management Protocol) is used for monitoring and controlling a
wide variety of different units in a network. Detailed information about this topic can be
found under http://www.wikipedia.org/.
A description of the unit - the MIB (Management Inform ation Base) - must be load ed in the
central unit ("manager") from which the transmitters are monitored.
A monitored unit contains a program ( "agent") which can answer querie s from the manager
and execute commands. Furthermore, the agent may of its own accord generate a message and send it to the manager. In this way, the central unit can be informed of a fault.
1.4.1 Installation
The MIBs required for monitoring and controlling a transmitter are stored as a ZIP archive
directly in the transmitter control unit and can be downloaded from there using any networkcompatible unit. All of the information required for configuration is contained in the MIBs
themselves.
When the transmitter is put into operation, both the agent in the tr ansmitter and the manager must be configured. Additional steps may be necessary if the transmitter is connected
via routers, firewalls or similar devices as they may block data packets.
The XX8000 transmitter family supports the versions SNMPv1 and SNMPv2c.
Alarms can be sent as v1Traps, v2Traps or v2Informs.
2098.0720.72 - 5.21 - E-2
Chapter 5 Operating
Several destinations can be set for fault messages (alarm sinks).
Several communities can be set with Read Only auth orization and Rea d/Write author i-
zation.
1.4.1.1 Settings on Transmitter Side
You can make settings yourself via the local disp lay (if available), the web se rver or SNMP.
The menu windows of the SNMP menu contain all the settings tha t are required for accessing a transmitter.
Note Changes to these settings are adopted immediately. The device does not need to be re-
started.
2098.0720.72 - 5.22 - E-2
Chapter 5 Operating
Note Detailed information about the individual parameters can be found in the descriptions of the
respective menu windows.
1.4.1.2 Settings on Manager Side
To be able to monitor and control a transmitter with SNMP, the MIB of the device and a program which can interpret the MIB must be available on the manager side.
You can load all available MIBs from any device using a web browser.
1. Log on using the web browser and select the SNMP Administration menu.
MIBs from Rohde&Schwarz and IRT are available. MIBs from IRT allow transmitters to
be linked using SNMP irrespective of the manufacturer. They are, however, limited with
respect to their functionality. When using IRT MIBs, you can select the "Inhibit Status"
for local operation (in the same way as for the parallel contacts). If this function is activated, no alarms/traps are sent when the transmitter is in l ocal mo de. You can activate/
deactivate this function using Inhibit Status in the SNMP > General menu window.
The MIBs have the naming convention RS-XX8000-<TV/Radio Standard>-<Standby
Concept/Option>-MIB. An example is RS-XX8000-ATV-TX-MIB for signal transmitters
for analog TV.
Examples of MIBs and contents:

2. Save the required ZIP file to your PC.
3. Load the following MIBs:
a) RS-COMMON-MIB
b) RS-XX8000-COMMON-MIB
c) MIB of the standby concept or option
A detailed description of the MIBs, the information that they cont ain and th e associated options is given below.
1.4.1.3 Testing SNMP Communication
SNMP communications is properly set up if you have loaded the MIBs in your program and
you are using the correct IP address of the transmitter and the correct commu nity. For queries and settings you must set the SNMP version in your manager; the transmitters detect
the used protocol automatically.
The following query can be used as a simple test:
In the example above, a transmitter with the IP address 10.123.10.7 queries the OID (ObjectIdentifier: unique designation of a data point) serialNumber
(.1.3.6.1.4.1.2566.127.1.2.167.1.1.1.2). The reply from the agent is 100111.
