Interface PROTOCOL Control System Accessories

To interface Audio-Visual equipment, PC's, alarm systems, Cinema projectors and other control systems to the Protocol dimming system Digital Lighting Systems,Inc. offers a line of accessories for interfacing the Protocol to timers, audio, A/V, alarm systems and others.

Also using the PROTOTIMER software, the PROTOCOL dimming system could be controlled from a computer creating timed events using the computer's internal clock. Requires the RAU-96 interface.


The PROTOCOL system may be controlled from anywhere via the internet using the RAU-96 remote system interface and an Ethernet adapter ( by others ) . For more information on products and availability please contact the factory.

Another easy way to connect to Audio Visual equipment is through infrared.  The PROTOCOL uses an RCA VCR standard code to mimic the pushing of buttons on a wall station. All that is needed is to put the VCR code in your IR transmitter.
