CHAPTER 2
Setup and Configuration
Power Hub to Projector
The power hub RS-232 connection to the projector allows DMX control of the projector's
shutter, lamp, focus and zoom function.
Power Hub to Orbital Head Connection
The Power Hub provides data and power to the Orbital Head through the two meter, 4-pin XLR
cable provided. This cable should not be lengthened.
Note: The cable has 1.5 mm
Head. Do not substitute a microphone or similar cable.
DMX Data Connection
The Power Hub connects to a DMX controller or another fixture on a DMX 512 link using a 5-
pin DMX512 data connector compliant with the USITT standard. See Connecting to a DMX512
Link for detailed instructions on data cable construction and connection.
Connecting to a DMX512 Link
The Orbital Head System can be controlled with a DMX console on a DMX512 link for real time
image manipulation and positioning.
The Orbital Head System can also operate without the server as a standalone fixture on a DMX
link to position projector output utilizing the moving Orbital Head.
Required Data Cabling and Connectors
To link one or more fixtures to a controller and/or to each other, obtain data cabling. Cabling
can be purchased from High End Systems® (see Accessories on page 2) or constructed
according to the following specifications.
High End Systems® recommends data-grade cable. Data-grade cable is designed to carry a
high-quality signal with less susceptibility to electromagnetic interference.
DMX Data Cables: Use Belden
applications) data cables with the following characteristics:
• Two twisted pairs (4-conductors) plus a shield
• Maximum capacitance between conductors: <15 pF/ft.
• Maximum capacitance between conductor and shield: 55 pF/ft.
• Maximum resistance: 20
• Nominal impedance: 120
Cable Connectors: The Power Hub accepts 5-pin XLR cable connectors. Cabling must have a
male XLR connector on one end of the cable and a female XLR connector on the other end.
Pin one is the common (cable shield), pin two is the data complement (negative), pin three is
the data true (positive). Pins four and five are not used, but they allow a secondary data link
to pass through the fixture, (see ).
