Serial Communications
Control Port (RS-232)
The MH2-HD can send and receive serial commands via RS-232 at any Baud rate
selected via BrightAuthor. The port is a modular RJ-45 jack; adapter cables are
available for 3.5mm or DB-9 serial ports. The port may be set for Null or Straight
using the switch located beside the RS-232 port.
Control Bus (RS-485)
The RS-485 control bus allows the MH2-HD to interact with devices such as the
Audio Authority TouchSelect panels or the 1895 Visual Volume knob. The MH2-HD
can also control switch modules or amplifiers that are linked by the Control Bus.
The MH2-HD 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.
