To control media using push-buttons, connect Easy Plug push-buttons to each position. Compatible push-buttons are available in several colors; shown to the right is the button illuminated with blue LED ring.

MicroSD Card Slot

Serial Communication

Control Port (RS-232)
The MH2-4K can send and receive serial commands via RS-232 at any Baud rate selected via BrightAuthor. The port may be set for Null or Straight using the switch located beside the RS-232 port. The port is a modular RJ-45 jack; adapter cables are available for 3.5mm or DB-9 serial ports.

Control Bus (RS-485)

The RS-485 control bus allows the MH2-4K to interact with devices such as the Audio Authority TouchSelect panels or the 1895 Visual Volume knob. The MH2-4K can also control switch modules or amplifiers that are linked via the Control Bus.

The MH2-4K is unit ID 0, all on-board push-button positions respond to commands addressed to ID 0. All commands are echoed on the RS-232 control port and RS-485 control bus, regardless of ID.
