Operation 
Operation can be performed locally on the built-in front panel control unit or 
remotely via the USB or Ethernet − LAN interface. Operational parameters 
such as setting the frequency, changing the channel spacing or activating 
presets can be controlled. In addition, the current status Information and 
indicators such as GO, ACTIVE, SQ, CARRIER or VSWR can be received 
from the transceiver and displayed. 
Maintenance 
Maintenance status parameters can be read out via the USB or 
Ethernet  − LAN interfaces, and the built-in front panel control unit. The 
transceiver delivers the result of the continuous built-in test (CBIT) and the 
event list, which saves all events with the time information of occurrence. 
Maintenance activities can be performed and controlled via the built-in front 
panel control unit and remotely via the USB or Ethernet − LAN interface. 
The transceiver provides commands for switching over from main to 
standby (and vice versa) and for performing a test transmission. In addition, 
the device can be reset or the real time clock (RTC) can be initialized locally 
or remotely. 
Performance values 
Performance values can be read out over the built in front panel control unit 
or over the Ethernet − LAN interface. Parameters such as 
modulation depth, temperatures, voltages, power levels, receive signal, 
audio level and VSWR can be measured. 
Configuration 
Configuration of the transceiver can be performed with the Service and 
Maintenance Tool R&S ZS 4200, which runs on a standard PC or laptop. 
Connected via service PC, the radio provides easy and fast configuration of 
the radio basic parameters such as IP address, PTT timeout, power audio-
levels and preset pages. 
The configuration files can be saved and loaded to the transceiver. The 
configuration process is very convenient and allows you to quickly configure 
an entire rack. In case of service, the defective radio can be “cloned” and 
the parameters loaded to a replacement radio. 
Preset loading 
Up to 200 preset pages can be loaded via the USB or Ethernet − LAN 
interfaces. 
Inventory 
All hardware and software components can be read out on all the USB or 
Ethernet − LAN interfaces and are visible on the built-in display. 
Software update 
The R&S DS 4200 software is delivered as a CD ROM and contains all 
software components, which are automatically loaded to the radio modules 
via the USB interface. The Service and Maintenance Tool R&S ZS 4200 
provides a software download manager, crosschecks the hardware and 
software and ensures a proper software download.
