System Overview
The Ghostband system is a wireless, wearable, LED lighting system controlled via a DMX lighting console. The
lighting console is connected through a Pathfinder processor to the GMT Transmitter which wirelessly
communicates to the Ghostbands. System connections are covered in Chapter 2, the configuration 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 3. Pathfinder processor.
Cables:
• The Pathfinder 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’).

Connections
The following paragraphs describe the connections of the Ghostband system.
Pathfinder Power - AC power is supplied to the Pathfinder 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.
Pathfinder LAN - Three Gigabit Ethernet ports exist on the rear of the Pathfinder and one on the front. All three
access the Pathfinder LAN. Use the Pathfinder LAN to access the web UI or to send ArtNet to the Pathfinder. For
newer consoles that support DMX control over Ethernet, the Pathfinder accepts Artnet II.
Pathfinder Inputs - In GMT mode, the Pathfinder accepts an ArtNet signal over the Pathfinder 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.
Pathfinder Output - Most of the time the DMX Output of Pathfinder 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 Pathfinder 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 Pathfinder 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 specific frequency to be used varies according to local conditions and ordinances and
must be coordinated with the Ghostbands. See Chapter 3 for the specifics of adjusting this setting.
Ghostband Wireless Input - When powered on, the Ghostband units will respond to the commands received from
the GMT Transmitter.

Configuration
Overview
Once all of the system components are physically connected, they must be configured. The three components to
configure 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 configuration is
done via a web UI running on the Pathfinder.
Transmitter Setup
In order to make a Pathfinder 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 Pathfinder 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 Assignments
Assigning Ghostbands to groups allows large numbers of devices to be controlled by a single fixture 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 Pathfinder’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
configured. When a Simple Fixture (Dimmer + RGB) profile is used, Ghostbands are controlled only by Block
Addresses.
Ghostband USER GUIDE
Ghostbands can simultaneously have both a Block Address and a Short Address. This becomes important when a
lighting console is configured 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 fixture 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 specific 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|ArtNet
Pathfinder accepts an ArtNet signal over the Pathfinder LAN or DMX 512 over the 5 pin XLR connector on the rear.
The settings in the Pathfinder must correspond to the settings of the lighting console. In other words, if the lighting
console outputs DMX on 5 pin XLR, the Pathfinder must be set to receive the signal on 5 pin XLR. The same holds
true for the starting address setting in Pathfinder and the ArtNet subnets and universes. If in doubt, check the
settings of the lighting console and set the Pathfinder 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 configured in the web UI of Pathfinder, we need to discuss the fixture types in more detail.
Simple Fixture
Blocks are controlled from a lighting console by two Simple Fixtures. Two fixtures 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.
Ghostband USER GUIDE
Advanced Fixture
The Advanced Fixture is used to create complex effects such as ripples, waves, and the FOLLOW ME effect
discussed earlier. The first Advanced Fixture that is patched in a lighting console is a broadcast fixture 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 first Advanced Fixture in the system can send broadcast messages to all Ghostbands. Additional Advanced
Fixtures control specific 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 Assignment
Figure 8 on the facing page, shows how the DMX channels are assigned in a five block system with a starting
address of one (1). Sixteen fixtures 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.

Pathfinder Web UI
In addition to the front panel, a Pathfinder can also be configured using the web UI. The web UI contains
Ghostband system specific settings that are not available on the front panel interface. The web interface can be
accessed by any web browser connected to the Pathfinder LAN via either the front or the rear Ethernet ports. The IP
address of the Pathfinder is reported by the front display of the Pathfinder as part of the status report banner that
cycles on the front display. Use the front panel interface of the Pathfinder if the IP address needs to be changed.
A Pathfinder processor can be configured to target several different types of systems, one of which is the
Ghostband system. The home page that is served by the Pathfinder will be the unique page for the target device
that the Pathfinder is currently configured for. Setting the target device for the Pathfinder can be accomplished
with the web UI of the Pathfinder or from the front panel interface. Figure 10 below, shows the GMT Transmitter
home page.
Figure 10. Pathfinder’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 Pathfinder. 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).

The Setup page of the Pathfinder shown in Figure 11 below, allows for configuration of Pathfinder specific settings
which also includes setting the target device. The baud rate setting is ignored in the case of the GMT Transmitter.
Numerical field values are sent to the Pathfinder each time the user exits a field. The web UI page will reload each
time a value is sent.

Scan 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.

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 identified by block address and by short address. Block addresses relate to the
simple (dim+RGB) fixtures 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 fields. The desired address is then entered into the address field. 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 field 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.

Lighting Up Ghostbands for Testing
1.
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 flash 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 Pathfinder. In order to
have such a Transmitter send commands to Ghostbands, a DMX console must be connected, patched and sending
commands to the Pathfinder.

Maintenance
Proper 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.

DMX Channels
The 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 fixture types.

Transmitter Emissions
The GMT Transmitter has roughly a 60º radiation pattern. The figure 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.
