For mission critical applications, we strongly recommend that a replacement ZeroWire Ultra 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 9.
Overview The ZeroWire Ultra 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. 1

Display Mounted Rx Wiring diagram
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. 7
Setup Bonding the Transmitter (Tx) and Receiver (Rx) Before the ZeroWire Ultra 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. First, verify that a ZeroWire Ultra channel is available. If the Tx’s LED is alternating between blue and yellow, then all ZeroWire Ultra channels are in use. See All Channels In Use Indication section on page 9 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. ZeroWire Ultra Tx and Rx units are not compatible with earlier ZeroWire Tx and Rx units. Attempting to bond a ZeroWire Ultra unit to an earlier ZeroWire unit will cause the ZeroWire Ultra unit’s LED to blink Yellow twice, then turn steady Yellow for one second, after which the pattern is repeated.

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. 8
Typical Installation Detailed Installation and Setup information starts on the following page.
Transmitter
Receiver
Display hardwired to image source (processor). NDSsi recommends ZeroWire Ultra 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.
All Channels In Use Indication Tx Indication: 1. When all channels are in use and a new ZeroWire Ultra 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.
Performance Performance: ZeroWire Ultra 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 Ultra 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. 9
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.
10
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 Ultra 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 continues on the following page.
5 inches (127 mm) minimum
5 inches (127 mm) minimum
Up to 8 ft. (2.4 m)
At least 5 ft. (1.5 m)
11
At least 5 ft. (1.5 m)
Test results indicate that ZeroWire Ultra 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.
12
Non Line of Sight Operation The ZeroWire Ultra 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.
13
Avoiding Co-Channel Interference If the ZeroWire Ultra 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 nine channels based on the result of its passive scan at power on. 3 Channel Operation: Operating more than three ZeroWire Ultra pairs in one area may result in co-channel interference. In order to avoid the potential of co-channel interference, a 75 foot (23 m) separation should be maintained between any two ZeroWire Ultra pairs that are operating on the same channel. The 75 foot (23 m) separation is a general guideline, the actual separation required to avoid co-channel interference may vary greatly. 9 Channel Operation: Up to 9 systems, may be operated within 75 feet (23 m) radius, with a maximum of 3 Tx / Rx pairs per room. The groups and the channels assigned to each group are listed below. Group Channels GR0 CH13, CH74, and CH9 GR1 CH14, CH73, and CH11 GR2 CH15, CH72, and CH10 The drawings below may be used as references for actual installations. For 3 channel installations use drawing 1. For 9 channel installations drawings 1 and / or 2 may be used. Some of the factors affecting how well the ZeroWire Ultra channels are isolated are listed below. These factors apply to both 3 channel and 9 channel operation. 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. Note: ZeroWire Ultra Tx / Rx pairs must be installed in the same room. Cross room operation is not supported

Advanced Features Overview: The Update Channel / Power Utility software and its usage instructions are on the CD included in the ZeroWire Ultra shipping box. The utility allows the user to configure some of ZeroWire Ultra transmitter and receiver parameters. The parameter settings are discussed in the following paragraphs. Note: These settings can only be changed using a computer to connect to a ZeroWire Ultra unit and running the Update Channel / Power Utility software. Channel Selection (Tx only): The user may select either the 3 channel or 9 channel option. The channel list for the 3-channel option is: 13 14 15, and the list for the 9-channel option is: 13 74 9 14 73 11 15 72 10. 9-channel is the default for ZeroWire Ultra. Note: ZeroWire Ultra Tx and Rx units are not compatible with earlier ZeroWire Tx and Rx units. Deep Sleep Selection (Tx only): The ZeroWire Ultra Tx goes into Deep Sleep after 3 minutes if no video input is detected, or if its corresponding Rx unit is powered off, or disconnected from the receiving display. Restoring video will “wake up” the Tx. The Deep Sleep feature is always ON and cannot be turned OFF Note: When the TX unit is in the Deep Sleep state, its LED’s cadence will be: blinking yellow for 1 second, then off for 3 seconds. To wake the Tx unit, press its bonding button and the TX’s LED switches to blinking amber. Also, restoring video will bring the Tx out of the sleep state. ATPC Selection (Tx & Rx): When ATPC set to OFF, the system will operate at maximum transmit power, making the wireless link more robust when obstructions to the line-of-sight are introduced. When ATPC is set to ON, the system transmits at a lower power level determined by the relative distance and signal quality between the Tx and Rx units. The advantage of having ATPC ON is that it allows more ZeroWire Ultra systems to operate in the same area by minimizing the transmit power and decreasing the potential for co-channel interference. The RX unit’s ATPC setting automatically matches the TX unit ‘s ATPC setting.
