Lens Data Display Ldd-Fp - ARRI ALEXA Series User Manual

172 ALEXA Plus
Wired Hand Adapter WHA-3
The WHA-3 allows both WFU-3 and WZU-3 to connect to the camera via
cable.
Zoom Main Unit ZMU-3
The ZMU-3 controls the the zoom axis. It can be connected to the
camera via cable to an LCS port, or via cable through an LCS port of an
WCU-3, or wirelessly by using a WZE-3.
Wireless Zoom Extension WZE-3
The WZE-3 is a radio system that enables direct wireless connection of
a ZMU-3 and a camera.
Hand Unit Priorization
Different priority levels are assigned to the hand unit devices to ensure
only one device has control over a motor at a time.
A device's knob that is assigned to an axis has a higher priority than a
device's slider assigned to the same axis. When steering items of the
same type are assigned to the same axis, the one connected via WRS
has highest priority, second highest priority has a device cable on the
upper LCS port, the lower LCS port has the lowest priority. Of two radio
devices with the same steering items assigned to the same axis, the
one that connects to the camera first gains control.
Cabled devices can gain control of an axis at the time of connection.
Wireless devices must be rebooted if an axis has become idle before
they can gain control.
An exception to the rule are devices on the zoom axis. Here the cabled
devices have the highest priority, with LCS port 1 having priority over
LCS port 2.
