5.3 Selecting the radio channel (“White Radio“)
The new “White“ radio has, aside from being available,
the advantage of offering more robust transmission
through direct sequence spread-spectrum and adjacent
channel rejection technologies. Thus the “White“ radio is
less prone to interference from other wireless devices
and can better co-exist with WLAN devices on the set.
The “White“ radio modem in the WCU-3 utilises a different
transmission scheme compared to the “Yellow“ radio,
therefore it is connecting to other “White“ radio equipment
only.
To establish a connection of one or more Wireless Hand
Control Units* (a maximum of three per radio channel is
possible), the WCU-3 must be set to the same radio
channel as the camera or the Motor Control Unit.
Please refer to Section 3.2 for unit‘s compatibility.
It is not possible to control more than one motor control
unit with one WCU-3.
Select the radio channel by pushing the jog-wheel at the
unit‘s lower side and select the Channel Menu . Refer to
Section 4.1 for details.
* WCU-3, WMU-3
Frequency range is the ISM 2.4 GHz. Modulation
scheme used is DSSS (Direct Sequence Spread Spec-
trum).
ARRI Ch. Nr. Frequency
0 2,410 GHz
1 2,415 GHz
2 2,430 GHz
3 2,435 GHz
4 2,450 GHz
5 2,455 GHz
6 2,470 GHz
7 2,475 GHz
In case two remote systems with white antenna washer
must work side by side on different channels, it is
recommended to set one of the systems to even channel
and the other system to a neighbor - odd - channel
number.
