PORK CHOPPER

model: PCHOP
technical data sheet

Pork Chopper [PCHOP] is an economical way to increase the total number of control channels from a Flying Pig Systems, Wholehog II console. It does this by decoding the special "Overdrive" signal that three of the four output ports are capable of producing into two DMX512 universes. Connecting Pork Choppers to three output ports increases Wholehog II channel capacity from 2048 to 3584 channels. That's an additional 1536 channels!

DMX isolator mode allows Pork Chopper to act as a DMX512 isolated splitter when the "Overdrive" signal is not present. LEDs indicate the presence of DMX512 or "Overdrive" signals on the input port, as well as mimic the intensity of channels 1 and 513 to aid in troubleshooting. The 1/10 inch powder coated aluminum chassis is built tough for years of service. One or two Pork Choppers can be mounted in a single rack space with optional rack kits.
