PRODUCT DESCRIPTION Doug Fleenor Design specializes in customizing, so your particular unit may differ in some respects from the product described in this Owner's Manual. This manual will describe the standard product and call attention to common customized features. The Rotor-Router is a DMX512 distribution system featuring up to 12 inputs and an unlimited number of outputs. A system typically consists of an input module and one or more output modules. Both modules are 1.
SPECIFICATIONS Input module Input circuit: Data. Input connectors: Output circuit: EIA-485 receiver with 120 ohm termination resistor between +Data and - Gold plated 5 pin male Neutrik D-1 series (terminal connections optional). EIA-485 transmitter with 60 ohm series (source) termination (DMX512 signals on a non-standard connector). Output connector: DB-25P. Output module Input circuit: EIA-485 receiver.
connector, input 2 is to the left of input 1, input 3 is to the left input 2, etc. This way the connectors are in the same order as the indicator LEDs when viewed from the front. DMX512 Standard Pinouts 1 - Common 2 - Data Complement (-Data) 3 - Data True (+Data) 4 - Auxiliary Data (No Connection) 5 - Auxiliary Data (No Connection) OPERATION The Rotor-Router Input Module has no operator controls. The Rotor-Router Output Module has one twelve position rotary switch associated with each output.
TECHNICAL DETAILS For those technical types out there, here is a brief description of how the DMX512 combine unit works. DMX512 uses a "differential" digital signal. A differential signal is a pair of signals which are inverse from one another. That is, when one is high, the other is low. Differential signals are common in both analog processing (balanced microphone cables) and digital processing (digital communications such as EIA-485).
TROUBLESHOOTING We hope your DMX512 combine unit never needs service. If it does, the information presented here may be of assistance. Access to the inside of the unit is accomplished by removing four top cover screws and removing the top cover. There is a 1/2 amp fast blow fuse inside the unit. If the POWER indicator does not illuminate when the line cord is plugged in, check the fuse. Board Level Troubleshooting Notes Power supply. The entire combine unit runs on +5 volts.
