Overview
The ZeroWire 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 an unlicensed ultra-wideband (UWB) wireless system in compliance with FCC (Part 15) rules
governing UWB.
The system is composed of a transmitter (Tx) and a receiver (Rx) pair. The Tx unit is designed to be
mounted on the rear top edge of a display on a surgical cart, or on the cart itself. The transmitter may
obtain its input video signal from either an endoscopic camera processor or the display’s re-drive output.
The Tx unit is 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 6.
The Rx unit is designed to be mounted on the rear top edge of a display, it may also be mounted on a cart,
and is 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 6.
A typical installation is shown on page 9.
*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 6.

Cable Bend Radius
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.

8
Setup
Bonding the Transmitter (Tx) and Receiver (Rx)
Before the ZeroWire 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 page 7 for Power Connector
location and ‘Y’ Adapter cable information.
The status indicator LED of each unit should be yellow and blinking slowly. If the LED’s are steady yellow
then the Tx and Rx pair is already bonded, continue at the Passing Video section below. 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. If the Tx’s LED is alternating between blue and yellow, then all ZeroWire channels are in use. See
All Channels In Use Indication section on page 10 for details.
2. Press and hold the “bond” button (see Figure 1 for location) on the Tx unit until its LED begins flashing
rapidly, then release. Next press and hold the “bond” button (see Figure 1 for location) on the Rx unit
until its LED begins flashing rapidly, then release.
3. When the bonding process is complete each unit’s LED will be steady yellow.
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 bonding completed, connect a DVI or SDI video source to the Tx unit and a display to the Rx unit
via its DVI output (Figure 2). The indicator LED’s should turn blue and the source image should appear on
the display. This completes the basic setup.

Performance
Tx Indication:
1. When all channels are in use and a new ZeroWire pair or a new Tx is turned on: The LED on the Tx will
alternate between blue and yellow continuously or until it finds a free channel. If a free channel is
found, then the LED will behave as described in Bonding Procedure on page 8.
2. When all channels are in use and the bonding button is pressed on a new Tx: The LED on the Tx blinks
fast yellow, indicating that the device is attempting to bond. If no channel is found, then the LED blinks
alternately between blue and yellow until the bonding times out. If an available channel is found, then
the LED will behave as described in Bonding Procedure on page 8.
Rx Indication:
Rx is not aware that all channels are in use.

NDSsi recommends ZeroWire 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.
Typical Installation
Detailed Installation and Setup information starts on the following page.
Performance:
ZeroWire HD Wireless 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 system:
1. Mount both components at least 5 feet (1.5 m) from the floor.
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 30 feet (10 m) or less .
4. The black surfaces of the transmitter and receiver should be vertical, facing each other and be visible to
each other in free air space. We do not recommend orienting the modules horizontally.
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.

10
Positioning and Orientation
Due to the shape of the antenna’s signal field (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. See image 2.
Horizontal Alignment:
Horizontal alignment should be within + or - 10° of horizontal. See image 3.
Positioning and Orientation is continues on the following page.

11
Elevation:
The Tx and Rx should be positioned at least 5 feet (1.5 m) above the floor, be at the same height, and,
preferably, with the black (front) surfaces of the Tx and Rx facing directly at each other.
Separation:
ZeroWire operates correctly with a 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).
At least 5 ft.
(1.5 m)
Up to 8 ft.
(2.4 m)
5 inches (127 mm) minimum 5 inches (127 mm) minimum
At least 5 ft.
(1.5 m)
Positioning and Orientation is continues on the following page.

12
Test results indicate that ZeroWire 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°, 130° and
180° relative to each other.
Aligning the Tx and Rx at 90° relative to each other provides the least acceptable link quality.

13
Non Line of Sight Operation
The ZeroWire system can maintain a wireless link even with 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.
