FCC Compliance Statements
WARNING: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
Note: The PhaseSpace Impulse system is delivered with shielded Ethernet
cables. Shielded Ethernet cables are required to comply with emissions
limits. It is the responsibility of the user to use the supplied cables.
Note: This equipment has been tested and found to comply within the
limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at their own
expense.
Industry Canada Compliance Statement
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du
Canada.
CE Compliance Statement
WARNING: This is a class A product. In a domestic environment this
product may cause radio interference in which case the user may be
required to take adequate measures.
WARNING: DO NOT connect or disconnect devices to the HUB while the
server computer is on. The LED Base Station is considered a device and
should only be connected or disconnected while the server computer is off.
WARNING: Only use standard shielded Ethernet cables with the
PhaseSpace system. DO NOT use crossover cables.
WARNING: The six-pin port on the LED Base Station is only to be used to
connect to LED Driver Units. DO NOT use this port to connect to any other
device.

1: LED System Description
The PhaseSpace LED (Light Emitting Diode) system can be classified as
the data-generating side of the PhaseSpace Impulse system. The individual
components of the system are described in this section.
1.1 LED Base Station
Figure 1.1.1: LED Base Station
The LED Base Station functions as the primary link between the
PhaseSpace HUB and the LED system. The base station is connected to
the HUB by connecting one end of an ethernet cable to a port on the HUB
and connecting the other end of the cable into the ethernet (RJ45) port on
the base station.
The LED Base Station has these functions:
5

• Transmission of timing signal to the LED Driver Unit(s)
• LED programming
The base station also has the capability to drive LED strings
independently.
The interfaces on the LED Base Station are:
• One 6-pin (RJ11) port
• One 8-pin ethernet (RJ45) port
• LED string ports
• External RF antennae
The LED Base Station transmits a timing signal via the RF antennae (or
directly through a 6-pin connection) to the LED Driver Unit. This signal is
sent once per frame.
1.2 LED Driver Unit
The LED Driver Unit is the driver of the LED modules. The unit consists of
a battery pack as well as an RF receiver, which receives a timing signal
from the LED Base Station. The interfaces on the upper edge of the driver
unit are (refer to Figure 1.2.2):
• A power/reset button
• A 6-pin (RJ11) port
• A 14-pin LED string port
In tetherless mode the LED driver unit is turned on by quickly depressing
the power/reset button. In tethered mode, the unit automatically turns on
when connected to the base station. To turn off the unit, the button should
be held down for at least a second.
IMPORTANT NOTE: If the power button is held down too long when
turning the unit on, the unit will not power up and it will be necessary
to wait a few seconds before the unit can be turned on.

Figure 1.2.1: LED Driver Unit
The battery pack is charged by connecting the driver unit to the LED driver
charger. From a completely discharged state the battery pack should take
two to three hours to fully charge.
Figure 1.2.2: LED Driver Unit connector view
A total of six LED strings can be connected to the 14-pin connector using
a six-wire breakout adaptor or a six-port breakout box.
The face of the LED driver unit has a set of function indicator lights (Figure
1.2.3).

Figure 1.2.3: LED Driver Unit indicators
The indicators give the following information:
• Battery Power - The leftmost column of four lights indicates battery
power
• Signal Power - The rightmost column of four lights indicates signal
power (tetherless mode)
• Driver Number – The numeric indicator shows the driver number
assigned to the unit. During calibration this indicator will display the
letter “C”.
• Mode / Profile – The bottom two lights of the group of four lights
near the center of the face of the unit show the mode / profile that
the system is using (refer to Figure 1.2.4).
• Signal / Streaming – The upper right light of the group of four lights
is on when the system is streaming data and a signal is being sent
to the unit.
• Charging – The upper left light of the group of four lights is on when
the unit is charging.

The LED driver unit is encoded by connecting it to the LED base station.
Within five seconds of connecting to the base station all the driver unit
indicator lights will turn on (refer to Figure 1.2.5). This is an indication that
the unit is ready to be encoded. For more information about encoding refer
to the PhaseSpace Impulse: Configuration Manager document.

1.3 LED Strings
An LED String consists of:
• The LED cable
• The LED cable connectors
The LED cable consists of two wires, one of which is colored. The
connector has two sockets, one for each wire of the LED cable.
A total of six LED strings can be attached to a single 14-pin connector,
which connects to the 14-pin LED string port on the LED Driver Unit. Each
LED string is capable of having up to 12 LED modules attached to it using
the proper LED connectors. Each LED module on a particular LED string
must have a unique LED designation, i.e. two LEDs with the same
designation should not be connected to the same string.
9

1.4 LED Modules
The LED modules contain the actual light sources that are tracked by the
PhaseSpace cameras. Along with the light source is a microprocessor that
controls the modulation of the LED’s pulse duration and amplitude.
Each LED has one of 12 LED designations (labeled A through L). This
designation along with the identifier of the LED driver gives each LED a
unique identifier.
Connecting an LED module to an LED string is illustrated in Figure 1.4.1.
The prongs of the LED module should be pushed completely into the
connector on the string. There is only one way to push the module into the
connector, so care should be taken not to force the connection.
Figure 1.4.1: Connecting LED Module to LED String
IMPORTANT NOTE: A maximum of 12 LED modules can be
connected to a single LED string and there cannot be any repeat of
LED designation on a single string.
