2.1 Configurations
This wireless transmission system combines with an HD LDK camera head to form a HD
Digital Wireless Camera system. The camera head with the attached Wireless Camera Adapter
(WCA), communicates wirelessly with the Antenna Management Unit (AMU). The AMU is
connected to the Wireless Control Unit (WCU) via a Triax cable.
For different RF frequency ranges, different wide band RF modules are available which cover
the ranges 2.2 to 2.4 GHz, 2.0 to 2.2 GHz or 2.5 to 2.7 GHz using 18 MHz bandwidth.
Output video signals
The WCU delivers three SDI video signals for the studio system. Each group (1&2/3) of signals
can be selected in the WCU Video menu to be HD or SD signals. SDI outputs 1 and 2 are
always the same (HD or SD) but SDI output 3 can be set independently.
Two analog CVBS and a digital monitoring signal (SDI output 3) are available from the WCU.
When used in HD mode, SDI1 & 2 group never contain OSD and when used in SD mode,
SDI1 & 2 group may contain OSD. SDI3 always contains OSD (in either SD or HD mode)
The OSD can be automatically switched off when Tally signal is active. This setting can be done
in the MONITORING
> MENU > MENU ONAIR
Control
Remote control of the camera is achieved through the C2IP network that can be connected to
the WCU. Control panels such as the OCP 400 can be used to gain full access to the camera.
Set the parameters for the control network in the WCU System menu.
Increased range
To expand the operating range of the camera an additional AMU with antenna set can be
added to the system. The WCU selects automatically between the two receiving sets without
a picture break (roaming).
