To provide a wireless link for a wide variety of
lighting controllers utilizing the industry
standard DMX-512 protocol.

• Range The desired range between the control
  unit and the power pack(s) should be a minimum of
  one hundred feet.
• Protocol The data will be transmitted using the
  industry standard protocol DMX-512.
• Frequency The frequency of operation will be in
  the VHF range at 433 MHz. This choice is to
  eliminate possible interference with other
  devices in the close proximity.
• XLR Data Port The XLR data port is the industry
  standard for lighting controller ports. Pin
  1-neutral, pins 2 3 carries the DMX signal,
  and pins 4 5 are unused.
• Power Requirements The power supply will be 9
  volts dc. This will supply the power for the
  transmitter/receiver and accompanying circuitry
  which requires 5 vdc and 3 mA.
• Receiver / Transmitter Input Output Levels
  The input levels will range between 0 5 volts.
• Antenna Characteristics In order to meet the
  size and technical requirements, a quarter-wave
  monopole antenna will be used.
• Cost The cost should be held to a minimum. Our
  goal is to keep the retail price less than
  150.00 for each individual unit.
