All Aux control panels are “MPK Bus” devices. The panels sit on our message-per-
keystroke “MPK Bus” for control panel communication. This serial data bus can
support up to sixteen 300-series panels daisy-chained on a single serial port of the
switcher mainframe or control panel. Looping connectors are provided to simplify
daisy chaining connections.
The rear panels of each CP-300 and CP-330 control panels are identical. Each one
has a power receptacle on the left side for input from the +5V DC supply. Two MPK
bus connectors are adjacent for looping the common control panel cable from unit
to unit and to the switcher mainframe or main panel.

The CP-3021 expansion panels are connected directly to the CP-3020 main control
panel module on a proprietary parallel bus. Two connectors are provided to easily
daisy-chain multiple expansion modules (max. 4) to the main panel. The CP-3021
expansion panels need no separate power supply.
