Intended Use and Contraindications
Overview
The ZeroWire G2 System allows wireless delivery of video signals from the DVI or 3G-SDI output of an
endoscopic camera processor or other video source to the DVI input of a video display. It operates as a
60Ghz-based wireless HD system in compliance with FCC (Part 15) rules governing the unlicensed 57-64
GHz band which is located in the millimeter-wave (mmW) portion of the electromagnetic spectrum.
A System is composed of a Transmitter and Receiver pair. The Transmitter and Receiver are designed to be
mounted on the top rear edge of a display. The Transmitter may obtain its input video signal from either
an endoscopic camera processor or the display’s DVI or SDI re-drive outputs. The Receiver’s output is
connected to a display’s DVI input The units are powered from an NDS 24 VDC power supply or through
the ‘Y’ adapter cable*.
The ‘Y’ adapter cable is described on page 6. A typical installation is shown on page 9.
*Note: The ‘Y’ adapter cables are only for use with NDS displays that are powered by an NDS 24
VDC power supply.
The NDS ZeroWire G2 is a paired wireless video communication transmitter and receiver, intended for
delivery of video signals from a source such as an endoscopy camera/processor, or other video source over
a radio-frequency link to a ZeroWire Receiver for display of images during endoscopic and general surgical
procedures. The ZeroWire G2 wireless video system is a non-sterile reusable device not intended for use in
the sterile eld.
Contraindications:
1. These units are non-sterile reusable devices and are not intended for use within a sterile field.
2. This equipment may not be used in the presence of flammable anesthetics mixture with air, oxygen or
nitrous oxide.

Note: The Transmitter and Receiver are not limited to line-of-sight operation, i.e., the pair will operate
reliably despite the presence of intervening obstacles. However, neither unit should be completely
surrounded by metallic objects.
Passing Video:
With the linking completed, the status LEDs should turn blue and the source image should appear on the
display. This completes the basic setup.
Setup
Linking the Transmitter and Receiver
Prior to placing the ZeroWire G2 system in service, the Transmitter and Receiver pair must be linked.
Once a Transmitter and Receiver pair is linked, they remain linked until the Transmitter is explicitly linked
to another Receiver or the Receiver is explicitly linked to another Transmitter.
Note: If a linked pair is turned off they will automatically link to each other when they are turned on again.
Linking Procedure:
1. Connect a DVI or SDI video source to the Transmitter unit and a display to the Receiver unit’s DVI
output (See Figure 1).
2. Press and hold the “LINK” button (see Figure 2) on the Receiver unit until its linking LED begins ashing
blue rapidly, then release. At this point, the user has 60 seconds to move to the other unit and press
the LINK button on that device.
3. Next, press and hold the “LINK” button (see Figure 2 for location) on the Transmitter unit until its
linking LED begins ashing blue rapidly, then release.
4. When the Transmitter and Receiver units identify each other and begin to link, both the Status LED and
Link LED on both units will ash rapidly for several seconds. Once the link is established, each unit’s
linking LED turns off.
Note: ZeroWire G2 Transmitter and Receiver units are not compatible with earlier ZeroWire
Transmitter and Receiver units.

that a display that is hard wired to the video source be immediately available whenever a surgical
procedure is in progress.
Typical Installation
Performance
Performance:
ZeroWire G2 HD Wireless Video System is intended and optimized for use in surgical or procedure rooms.
Use outside of a clinical environment is not recommended.
The following steps will help you to achieve optimal performance of the ZeroWire G2 system:
1. Mount both components at least 5 feet (1.5 m) from the oor.
2. Ideally, both the transmitter and receiver should be at the same height.
3. For a reliable video link, please follow the setup guidelines under Positioning and Orientation on pages
10 and 11.
4. The transmitter and receiver should be facing each other and be visible to each other in free air space.
5. For non line of sight applications, we recommend that the Transmitter and Receiver be located within
6 feet (1.8 m) or less from the walls.
Transmitter Receiver

10
Positioning and Orientation
Due to the shape of the antenna’s signal eld, both Transmitter and Receiver units should be installed so
they are aligned vertically and horizontally within ±10°.
Vertical Alignment:
Vertical alignment should be within ±10° of vertical.
Horizontal Alignment:
Horizontal alignment should be within ±10° of horizontal.

Elevation:
The Transmitter and Receiver should be positioned at least 5 feet (1.5 m) above the oor, be at the same
height, and, preferably, with the Transmitter and Receiver front edges parallel and facing each other.
Separation:
ZeroWire G2 operates correctly with a Transmitter and Receiver separation of up to 30 feet (9.1 m).
However, in the case of most OR environments, best results are achieved with a Transmitter and
Receiver separation distance of up to 8 feet (2.4 m).

Non Line of Sight Operation
The ZeroWire G2 System can maintain a wireless link with partial obstructions. However, best performance
is realized with a clear line-of-sight between units. In an OR environment, the ceiling mounted boom
system and its spring arm junctions, along with surgical light heads, are large metal structures that can
potentially block the wireless signals if they obstruct the line-of-sight between the Transmitter and
Receiver (see illustration below). Preferably, surgical lights should be positioned out of the way or raised
above the line-of-sight. If an object must obstruct the line-of-sight, the best option is to position it half way
between the Transmitter and the Receiver.
OR rooms whose walls and/or ceiling are constructed with metal sheets may reduce ZeroWire G2
performance. This condition possibly can be mitigated by moving the Transmitter and Receiver closer to
each other, setting their line-of-sight to 0 degrees (see page 10), and ensuring that there are no
obstructions between the Transmitter and the Receiver.
