Wireless Zoom Unit WZU-3
The WZU-3 controls the zoom axis. It connects to the camera through a WMU-3 or a
WHA-3.
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 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.
15.3 Lens Data Display LDD-FP
The Lens Data Display for Focus Pullers LDD-FP can be used to display lens
information. Connect it to the LDD port of the Plus module.
15.4 Plus Camera Controls
The ALEXA SXT Plus has an additional function button labeled WRS (Wireless
Remote System). It gives access to the WRS screen, from where all camera settings
related to the Plus camera features can be handled.
The WRS screen gives an overview of radio status, camera level, LDS status, and
CLM status. The screen buttons lead to screens containing more detailed info on
these topics and where settings can be changed.
