System Control
The Remote Control Bus Hub provides eight parallel ports for the connection of remote control
devices to an Nexia® system. Each port can accept multiple remote controls connected in a 5-
wire daisy-chain. A single Hub, connected to a single Nexia unit, allows multiple branches to be
added to the remote control network. Also, maximum cable length is calculated only across the
two longest network branches, thereby effectively extending the network range. The Remote
Control Bus Hub can be used with any combination of control devices, including
,

Third-Party Control
After initial programming & configuration, NEXIA systems may be controlled by RS-232
communication from third-party control systems such as AMX® or Crestron®, using the Serial
Control Port. See
RS-232 and Telnet Protocol
Overview
Nexia can be controlled via the control dialogs in the Nexia software, or via third-party controllers
using
For control of Nexia, Biamp created NTP (Nexia Text Protocol). This simply means that Nexia will
accept strings of ASCII characters to control and read settings of gain, mute, logic state,
frequency, audio levels, and other parameters of DSP Blocks in Nexia products.
NTP strings can be sent via third-party controllers using RS-232 (see
) or Telnet
via TCP/IP (see
). A line feed needs to be sent after each command string sent.
The NTP string is structured in the following order:
