SETUP AND CONNECTIONS
The Rotor-Router is designed to be rack mounted in a standard 19" equipment rack. Each Rotor-
Router module is one rack space high.
Plug the Rotor-Router's line cord into a grounded electrical outlet. The unit requires between 100
and 120 volts, 50 or 60 hertz. It requires less than 1/10 amp (12 watts). It should be grounded for
maximum electrical noise isolation and safety. The earth ground is connected only to the chassis.
All circuitry is isolated from the chassis and the power cord's ground pin.
The input and output connectors are 5 pin "XLR style" connectors as specified in the DMX512
standard (terminal block and three pin XLR connectors are optional). Plug the DMX512 signal
sources into the male connectors. Plug the DMX512 receivers into the female connector. The
mating connector for the input is a 5 pin female connector such as the Switchcraft model A5F or
Neutrik model NC5FX. The mating connector for the output is a 5 pin male connector such as the
Switchcraft model A5M or Neutrik model NC5MX.
When viewed from the rear of the unit, the inputs are installed right to left: input 1 is the rightmost
