System OverviewThe Ghostband system is a wireless, wearable, LED lighting system controlled via a DMX lighting console. The lighting console is connected through a Pathnder processor to the GMT Transmitter which wirelessly communicates to the Ghostbands. System connections are covered in Chapter 2, the conguration of each components is covered in Chapter 3. Finally, best practices for getting the most out of the Ghostband system is covered in Chapter 4.The major components of a Ghostband system are:Figure 1. Ghostband wristbands.Figure 2. GMT Transmitter.Figure 3. Pathnder processor.Cables:•The Pathnder power input cable is a standard C14 (IEC) connector (female) , terminated in any suitable male connector on the opposite end. •GMT Transmitter receives power and data on XLR 5 pin cables. These cables must have all 5 conductors. The maximum length of this cable is 200m (660’).11Ghostband USER GUIDE

GhostbandThe Ghostband is a silicone wristband. It houses an LED module and diﬀusion material in a central cavity. The LED module is a small rectangular battery powered device with 2 SMD LEDs. All Ghostbands have a unique serial number.Figure 4. Ghostband components.GMT TransmitterThe Transmitter is a lightweight plastic enclosure for the transmission circuitry of the Ghostband system. A bracket at the top holds a trigger clamp for mounting the device. A small push button addressing switch, power and data indicators and the input and output connectors all live above the label plate. The GMT Transmitter broadcasts in a 60 degree beam width from the base of the enclosure. See Appendix B for details regarding emissions. Figure 5.

Connections25The following paragraphs describe the connections of the Ghostband system.Pathnder Power - AC power is supplied to the Pathnder on a C14 style connector. Adjacent to the power input connector is a toggle switch. At the point that power is turned ON, the blue power indicator on the front panel will be lit and the system will begin to boot. After about 5 seconds the unit will be fully booted and the front panel display will begin to cycle through various status reports. Pathnder LAN - Three Gigabit Ethernet ports exist on the rear of the Pathnder and one on the front. All three access the Pathnder LAN. Use the Pathnder LAN to access the web UI or to send ArtNet to the Pathnder. For newer consoles that support DMX control over Ethernet, the Pathnder accepts Artnet II. Pathnder Inputs - In GMT mode, the Pathnder accepts an ArtNet signal over the Pathnder LAN or DMX 512 over the 5 pin XLR connector on the rear. See Appendix A for the full list of DMX channels and functions. Pathnder Output - Most of the time the DMX Output of Pathnder is electrically a straight pass-thru. When the GMT Transmitter is set as the target device, the DMX Output connector is electrically disconnected from the DMX Input connector and the Pathnder sends both power and data to the GMT Transmitter through the DMX Output port. All 5 pins of the XLR cable must be connected for the system to operate.GMT Transmitter XLR Input - The GMT Transmitter receives the power that it needs to operate (24VDC) and a data signal from the Pathnder on an XLR 5 pin connector. GMT Transmitter XLR Output - The GMT Transmitter can be serial chained via the XLR output to up to three additional units (a system total of four GMT Transmitter(s). Always terminate the last Transmitter’s XLR output connector with a standard 5 pin XLR terminator. GMT Transmitter Wireless Output - The frequency that is used for communication to the Ghostbands is in the 770MHz-934 MHz range. The specic frequency to be used varies according to local conditions and ordinances and must be coordinated with the Ghostbands. See Chapter 3 for the specics of adjusting this setting.Ghostband Wireless Input - When powered on, the Ghostband units will respond to the commands received from the GMT Transmitter.

Configuration37OverviewOnce all of the system components are physically connected, they must be congured. The three components to congure are: Transmitters, Ghostbands, and DMX/Artnet settings. Transmitters need to be discovered and set to match the frequency of the Ghostbands. Ghostbands need to be grouped to make large numbers of them easier to manage within the lighting console. Finally, DMX/Artnet settings need to be aligned with the lighting console so that the system integrates with the rest of the lighting being used in the production. All of this conguration is done via a web UI running on the Pathnder.Transmitter SetupIn order to make a Pathnder aware of a connected Transmitter, the system must be told to scan for any available Transmitters. The system is being designed to have a maximum of four Transmitters, however at the time of this writing only one Transmitter is fully supported. Once the Pathnder is aware of the connected Transmitter it will report back the settings it gets from the unit. In order for the Ghostbands to receive the Transmitter's signals the operational frequency needs to be the same as the one the Ghostbands are set to. To meet emissions regulations, the power setting must be set to an approved power level for the frequency in use. Later on in this chapter, the frequencies and power settings are listed as a table.Ghostband Group AssignmentsAssigning Ghostbands to groups allows large numbers of devices to be controlled by a single xture on a lighting console. This is useful as there are usually thousands of Ghostbands in a show environment, compared to dozens or hundreds of lights. Putting all of the Ghostbands into a single group makes them easy to deal with, but limits the visual eﬀect by having all of the bands running the same eﬀect. So, Ghostbands are usually broken up into about 5 diﬀerent groups.Grouping Ghostbands is done from the Pathnder’s web UI well in advance of the show time. Ghostbands can be grouped in two ways. Groups can be created by either Block Addresses or Short Addresses. The decision of whether to use a Block Address or Short Address for Ghostbands, stems from the way the DMX lighting console is congured. When a Simple Fixture (Dimmer + RGB) prole is used, Ghostbands are controlled only by Block Addresses. Ghostband USER GUIDE

8Ghostband USER GUIDEGhostbands can simultaneously have both a Block Address and a Short Address. This becomes important when a lighting console is congured so that the same group of Ghostbands are controlled by both a Simple and an Advanced Fixture. Appendix A has the full tables of DMX channels and function values for both xture types. The Short Address is an addressing mode with priority over Block addressing. For a Ghostband to receive a Short Address radio message, the message must contain either the specic short address of the Ghostband or have the message sent as a broadcast. A group of Ghostbands can be assigned the same Short Address or the Short Address can be assigned to only a single device. For example, if a Ghostband that a performer is wearing is assigned an individual Short Address, this device can be controlled separately from the group of audience Ghostbands. The Ghostband system then allows the audience Ghostbands nearby to react to the performer’s Ghostband, creating spatial visual eﬀects around the performer. This is called the FOLLOW ME mode.DMX|ArtNetPathnder accepts an ArtNet signal over the Pathnder LAN or DMX 512 over the 5 pin XLR connector on the rear. The settings in the Pathnder must correspond to the settings of the lighting console. In other words, if the lighting console outputs DMX on 5 pin XLR, the Pathnder must be set to receive the signal on 5 pin XLR. The same holds true for the starting address setting in Pathnder and the ArtNet subnets and universes. If in doubt, check the settings of the lighting console and set the Pathnder to correspond.In order to assess the quantity of Simple Fixtures and/or Advanced Fixtures that need to be patched on the lighting console and congured in the web UI of Pathnder, we need to discuss the xture types in more detail.Simple FixtureBlocks are controlled from a lighting console by two Simple Fixtures. Two xtures are used because the block is split by serial number, with all even-numbered bands on one Simple Fixture, and all odd-numbered bands on the other. The minimum number of Simple Fixtures on the lighting console will always be two. As an example, when Ghostbands are used in a pre-arranged order in a stadium type application, each seating section can be assigned to a Block Address to enable chases around the stadium where each section lights up in turn. In order to light an entire block, both of the Simple Fixtures controlling the block would be used.When the Ghostbands are used in a random audience situation like a festival, Blocks help create lighting eﬀects limited to sections of the audience rather than having eﬀects always light the whole audience.

9Ghostband USER GUIDEAdvanced FixtureThe Advanced Fixture is used to create complex eﬀects such as ripples, waves, and the FOLLOW ME eﬀect discussed earlier. The rst Advanced Fixture that is patched in a lighting console is a broadcast xture and the commands it sends will be received by all Ghostbands (as long as the short address is set to 65535). Eﬀects can also be limited to just one block of Ghostbands if multiple Advanced Fixtures are patched into the lighting console. Only the rst Advanced Fixture in the system can send broadcast messages to all Ghostbands. Additional Advanced Fixtures control specic blocks. For instance, the second Advanced Fixture controls Ghostbands assigned to Block 1. If three Advanced Fixtures are patched, then only Ghostbands assigned to Block 2 will respond to the messages from the third Advanced Fixture. This hold true for each additional Advanced Fixture. NOTE: Short addressing and Block addressing can be combined to control groups within groups.DMX Channel AssignmentFigure 8 on the facing page, shows how the DMX channels are assigned in a ve block system with a starting address of one (1). Sixteen xtures are required in this case because both Simple Fixture control and Advanced Fixture control are desired. Advanced Fixtures will always appear after the Simple Fixtures in the console patch. Blocks are divided into odds and evens when controlled by Simple Fixtures. Advanced Fixtures use Short addresses to control entire blocks.

Pathnder Web UIIn addition to the front panel, a Pathnder can also be congured using the web UI. The web UI contains Ghostband system specic settings that are not available on the front panel interface. The web interface can be accessed by any web browser connected to the Pathnder LAN via either the front or the rear Ethernet ports. The IP address of the Pathnder is reported by the front display of the Pathnder as part of the status report banner that cycles on the front display. Use the front panel interface of the Pathnder if the IP address needs to be changed.A Pathnder processor can be congured to target several diﬀerent types of systems, one of which is the Ghostband system. The home page that is served by the Pathnder will be the unique page for the target device that the Pathnder is currently congured for. Setting the target device for the Pathnder can be accomplished with the web UI of the Pathnder or from the front panel interface. Figure 10 below, shows the GMT Transmitter home page. Figure 10. Pathnder’s home page for the GMT Transmitter.If the page that is being displayed is not the home page of the Ghostband system shown above, it will be necessary to change the target device of the Pathnder. This can be done on the Setup page. In order to reach the Setup page press the Setup button at the top right corner of the home page (outlined in red in Fig. 10 above).12Ghostband USER GUIDE

The Setup page of the Pathnder shown in Figure 11 below, allows for conguration of Pathnder specic settings which also includes setting the target device. The baud rate setting is ignored in the case of the GMT Transmitter. Numerical eld values are sent to the Pathnder each time the user exits a eld. The web UI page will reload each time a value is sent. Figure 11. Processor setup page.Ghostband Home PageScan Antennas - In order to begin the setup of a GMT Transmitter press the Scan Antennas button. The line below will be populated with the details of the Transmitter(s) that are found. At the time of this writing the system only fully supports a single Transmitter set to address one (1).Name - The Transmitter can be named anything that makes sense for the system being setup. Frequency - The frequency of the transmission should be set to match the frequency that the Ghostbands are set to*. At the time of the writing of this guide, all Ghostbands are set to 916 Mhz. TX Power - Possible settings are 0-36. The Transmit power should be set as per the following table. The power will diﬀer depending on the frequency in use and the region of operation.Ghostband Regional Frequency Ranges* The frequency that Ghostbands operate on is currently set in the rmware of the Ghostbands.13Ghostband USER GUIDEFrequency(MHz)RegionBandApproved Power Setting780-786ChinaChinese WPANTBA864-869EuropeEU SRD 26903-927USANorth America ISMTBA916-929JapanJapanese BandTBA916-927AustraliaISMTBA

Test Mode - This is a range test that can help with the layout and design of the system. The Ghostbands will illuminate either GREEN, AMBER or RED depending on the received signal strength (red being the weakest).Energy Scan - This button will display a new page where a BAND4 (769Mhz-832MHZ) or BAND5(833-935MHz) scan can be selected. A list of energy levels in dBm will be displayed for each frequency from -99dBm to -14dBm. A value of -99 means that the channels is clear.LBT - Listen Before Transmit, this function ensures that any other transmissions on the same frequency as the Ghostband system, are not stepped on. This function is required to meet European radio regulations.Assignments - Ghostbands can be identied by block address and by short address. Block addresses relate to the simple (dim+RGB) xtures while short addresses relate to the Advanced Fixture. When creating assignments, if Ghostband serial numbers are all known, the start and end serial number of each block is entered into the respective numerical elds. The desired address is then entered into the address eld. Select, Assign Block Address or Assign Short Address to choose how the value will be assigned. If Ghostbands serial numbers are not known, simply turn on the units one block at a time and use the maximum address range of 0 for the start address and 9999999999 for the end address to broadcast the address assignment.Show Start Show End Frequencies - This is an experimental feature that must be used with Ghostbands in auto scan mode. It allows the operator to narrow down the number of frequencies that the Ghostband must scan. Contact a GMT eld application engineer before using this mode.DMX | Artnet Settings - DMX mode toggles between receiving DMX over Ethernet via Artnet or via 5 pin XLR. If Artnet is to be used, set the Subnet and Universe to the appropriate values. DMX address is the starting address for the channel blocks. The quantity of Simple Fixtures needed is determined by the number of blocks in the system. Add Advanced Fixtures if the functionality is required.14Ghostband USER GUIDE

15Ghostband USER GUIDELighting Up Ghostbands for Testing1. Ensure that the bands have fresh batteries installed in the correct polarity. 2. The Ghostbands have a pushbutton at the center of the LED module. Press and hold the pushbutton until the LEDs of the Ghostband light green and then turn oﬀ (about two seconds). 3. As soon as the LEDs go out, let go of the pushbutton. The band is now on and active.If the center button is held down for a total of four seconds, the LEDs will ash red and the unit will be oﬀ.Once the bands have been powered on they are available to receive the signals from the Transmitter(s). Transmitters can be placed in a test mode where they will broadcast a cycling test message to illuminate all Ghostbands. There are two ways to place a Transmitter in test mode; 1. Address a Transmitter to zero with the address switch. 2. Tick on the Test Mode checkbox on the GMT home page of the web UI.When a Transmitter is set to an addresses 1-4 it is listening for commands coming from the Pathnder. In order to have such a Transmitter send commands to Ghostbands, a DMX console must be connected, patched and sending commands to the Pathnder.

Maintenance416Proper maintenance of the Ghostband system equipment involves periodically checking the hardware for any parts that may have come loose or become damaged. Connectors should be checked and replaced if housings have become damaged or pins are bent or deformed. The Ghostbands can be reused. Encourage the attendees of your events to return the bands. Cleaning of the Ghostbands involves removing the LED Module and the diﬀuser from the silicone band. Recycle the batteries and set the LED modules aside for functionality testing. The wristbands (with LED module and diﬀuser removed) can then be cleaned in a solution of water and mild soap, rinsed and air dried on racks. Alternately, the silicone bands (with LED module and diﬀuser removed) can also be cleaned in an ultrasonic cleaning tank.Ghostband USER GUIDE

DMX ChannelsA17Ghostband USER GUIDEThe Ghostband units can be controlled via DMX channels either as Simple Fixtures, an Advanced Fixture or both. A Simple Fixture has four channels (Dimmer + RGB) the Advanced Fixture contains 33 channels. When controlled by Simple Fixtures, Ghostbands react directly to the color and intensity assignments coming from the lighting console. The Advanced Fixture channels have a much more complex relationship. Multiple channels must be set simultaneously in order to program complex eﬀects. The Advanced Fixture for Ghostbands can co-exist simultaneously with Simple Fixtures. This is because the Ghostbands simply react to the last sent command. Tables 4 and 5 detail the channel assignments of both xture types.Simple FixtureChannelDescriptionDecimalDefaultComments1Dimmer0-2550Master level2Red0-255255Red intensity3Green0-255255Green intensity4Blue0-255255Blue intensity

Transmitter EmissionsB21Ghostband USER GUIDEThe GMT Transmitter has roughly a 60º radiation pattern. The gure below indicates the emission point is at the base of the enclosure. For ideal placement of the Transmitter, imagine a 60° cone projected from the base toward the audience. The Transmitter should be placed high enough that the entire audience is covered by this cone. To increase the coverage area, the Transmitter can be placed at the edge of a space and pointed diagonally down, but for optimal performance there should still be line of sight from the Transmitter to the position of each Ghostband. Placing the Transmitter at ground level and aiming it across the audience is not ideal, as closer patrons will block those in the distance.Figure 12. GMT Transmitter Emission PointThe following azimuth plots show the radiation patterns of the GMT Transmitter at two common frequencies.Figure 13. Antenna Gain dBi (868 MHz)60º
