This manual is designed to assist the user with installation, setup and operation of the NDS ZeroWire®
G2 Wireless HD video system.
A numbered tab on the side of the page denotes the beginning of a section.
The functional descriptions in this manual are representative of:
Part Numbers:
90T2071 = ZeroWire G2 Receiver
90T2072 = ZeroWire G2 Transmitter (Input: DVI and 3G-SDI)
Manual Part Number: 60A0571 Rev A 27 February 2015
The ZeroWire G2 transmitter and receiver pair 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 millimetre-wave (mmW) portion of the electromagnetic
spectrum. At any time, a minimum separation of 20 cm must be maintained from the operating device and
the user or patient.
The system is composed of a transmitter (Tx) and a receiver (Rx) pair. The Tx and Rx are designed to be
mounted on the top rear edge of a display on a surgical cart. The Tx may obtain its
input video signal from either an endoscopic camera processor or the display’s DVI or SDI re-drive outputs.
The Rx’ output is connected to the display’s DVI input The units are powered from the provided 24 VDC
power supply (“wall-wart”) or through the optional ‘Y’ adapter cable*. The ‘Y’ adapter cable is described on
page 4. A typical installation is shown on page 8.
*Note: The ‘Y’ adapter cables are for use with displays that are powered by 24 VDC and whose
power connector accepts one of the J2 connectors shown on page 4.
The NDSsi ZeroWire G2 Wireless HD Video System is a paired transmitter and receiver, intended for
delivery of video signals over a radio-frequency link to a video display during endoscopic and general
surgical procedures. The ZeroWire G2 Wireless HD Video System is a non-sterile reusable device not
intended for use in the sterile field. It is intended for use by qualified physicians having complete
knowledge of these surgical procedures.
Contraindications:
1. These units are non-sterile reusable devices and are not intended for use within a sterile eld.
2. This equipment may not be used in the presence of ammable anesthetics mixture with air, oxygen or
nitrous oxide.
No part of this product may come in contact with a patient. Never touch the product and a patient at the
same time.
For mission critical applications, we strongly recommend that a replacement ZeroWire G2
transmitter and receiver pair, and a DVI cable be immediately available. Additionally, we
recommend that a display that is hard wired to the video source be immediately available
whenever a surgical procedure is in progress. See typical installation drawing on page 10.
OR rooms whose walls and/or ceiling are constructed with metal sheets, may reduce ZeroWire G2
performance. This condition can be mitigated by moving the Tx and Rx closer to each other, setting
their line-of-sight to 0 degrees (see item 1 on page 12), and ensuring that there are no obstructions
between the Tx and the Rx.

We recommend that the bend radius of metallic cables be no less than 2.5 inches (63 mm) or 7 times
the diameter of the cable whichever is greater. Sharper bends may damage the cable and / or
degrade the video signal.

Note:
The transmitter and receiver are not limited to line-of-sight operation, i.e., the pair will operate
despite the presence of intervening obstacles. However, neither unit should be completely surrounded by
metallic objects.
Passing Video:
Before attempting bonding, connect a DVI or SDI video source to the Tx unit and a display to the Rx unit
via its DVI output (Figure 2). Once the bonding completed, the indicator LED’s should turn blue and the
source image should appear on the display. This completes the basic setup.
Bonding the Transmitter (Tx) and Receiver (Rx)
Before the ZeroWire G2 wireless system can be put into service , the Tx and Rx pair must be
bonded. Connect an included power supply or a ‘Y’ Adapter cable to a Tx and an Rx unit. See pages 4
and 5 for ‘Y’ Adapter cable information and Power Connector location.
Once a Tx and Rx pair is bonded, they remain bonded until the Tx is explicitly bonded to another Rx or
the Rx is explicitly bonded to another Tx. Note: If a bonded pair is turned off they will automatically
bond to each other when they are turned on again.
Bonding Procedure:
1. Press and hold the “bond” button (see Figure 1 for location) on the Tx unit for 5 seconds, then release.
Next press and hold the “bond” button (see Figure 1 for location) on the Rx unit until for 5 seconds,
then release.
2. When the bonding process is complete each unit’s LED will be steady blue.
ZeroWire G2 Tx and Rx units are not compatible with earlier ZeroWire Tx and Rx units.

NDSsi recommends ZeroWire G2 for primary and secondary displays. However, for patient
safety a display that is cable connected to the video source shall be immediately available
whenever a surgical procedure is in progress.
Detailed Installation and Setup information starts on the following page.
Performance:
ZeroWire G2 Wireless HD Video System products are intended and optimized for use in a
surgical operating room (OR). Use outside of an OR 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, the distance between transmitter and receiver should be 15 feet (5 m) or less .
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 Tx and Rx be located no more than 6 feet
(1.8 m) from the walls of the OR.
8

Due to the shape of the antenna’s signal eld (image 1), both Tx and Rx units should be installed so they
are vertical within + or - 10°, and horizontal within + or - 10°.
Vertical Alignment:
Vertical alignment should be within + or - 10° of vertical.
Horizontal Alignment:
Horizontal alignment should be within + or - 10° of horizontal.
Positioning and Orientation is continued on the following page.
9

Elevation:
The Tx and Rx should be positioned at least 5 feet (1.5 m) above the oor, be at the same height, and,
preferably, with the gray (front) surfaces of the Tx and Rx facing directly at each other.
Separation:
ZeroWire G2 operates correctly with a Tx and Rx separation of up to 30 feet (10 m). However, in the case
of most OR environments, best results are achieved with a Tx and Rx separation distance of up to 8 feet
(2.4 m).
Positioning and Orientation is continued on the following page.

(2.4 m)
At least 5ft.
(1.5 m)

Test results indicate that ZeroWire G2 achieves a better signal-to-noise ratio when the Tx and Rx are
oriented at certain angles relative to one another.
Optimum link quality is achieved when the Tx and Rx are aligned at 0° relative to each other.
Acceptable link quality is achieved when the Tx and Rx are aligned at angles between 0 to 45°, 90° and
180° relative to each other.
Aligning the Tx and Rx at 180° relative to each other provides the least acceptable link quality.

The ZeroWire G2 system can maintain a wireless link with partial obstructions. However, best
performance is realized with a clear line-of-sight. 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 RF signals if they obstruct the line-of-sight between the Tx and Rx (see image 1 below).
Preferably, the 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 Tx and the
Rx.
OR rooms whose walls and/or ceiling are constructed with metal sheets, may reduce ZeroWire G2
performance. This condition can be mitigated by moving the Tx and Rx closer to each other, setting
their line-of-sight to 0 degrees (see item 1 on the previous page), and ensuring that there are no
obstructions between the Tx and the Rx.

If the ZeroWire G2 deployment is a typical one-system per room, there is essentially no restriction. The transmitter’s
Channel Selection feature picks the channel that is least susceptible to interference from the available six channels
based on the result of its scan at power on.
Some of the factors affecting how well the ZeroWire G2 channels are isolated are listed below.
1) The thickness and material of the room walls.
2) The opening and closing of room doors.
3) The room’s ceiling structure and the materials used in its construction.
*Notes:
ZeroWire G2 Tx / Rx pairs must be installed in the same room. Cross room operation is not supported
When multiple Tx /Rx pairs are installed in a given room, each pair must be powered up separately.
