Component Objects

Mic/Line Inputs:

These four plug-in barrier strip connectors provide balanced input for

microphone or line level signals. For unbalanced input, wire high to (+) and ground to both ( ) &
(-). Settings for these inputs are accessed by double-clicking the

PM Input 4 Channel

block in the

Layout.

Stereo Line Inputs:

These six RCA jack pairs provide unbalanced input for stereo line level

signals. Settings for these inputs are accessed by double-clicking the

PM Input (Stereo) 12

Channel

block in the Layout.

Outputs:

These six plug-in barrier strip connectors provide balanced output of line level signals.

For unbalanced output, wire high to (+) and ground to ( ), leaving (-) un-connected. Settings for
these outputs are accessed by double-clicking the

PM Output (Stereo) 6 Channel

block in the

Layout.

NexLink:

These two RJ45 jacks provide the NexLink Tx (transmit) and Rx (receive) connections.

Up to four NEXIA devices may be linked together to share digital audio signals. Tx on one NEXIA
device is connected to RX on the next device. NexLink utilizes straight through shielded CAT5
cabling, with a maximum recommended length of 5 meters per cable. When multiple NEXIA
devices are placed in the Layout,

NexLink

blocks allow routing of digital audio between linked

devices.

Ethernet:

All NEXIA devices use Ethernet, both for system programming and control.

Programming is accomplished using the NEXIA software provided with each unit. NEXIA software
is for PC computers, with Windows® XP Professiona/Vistal operating system required. The PC
computer must have a network card installed, which supports 10/100BaseT Ethernet. A
10/100BaseT Ethernet switch (not hub) is required when networking multiple units (see

System

Network Considerations

). Ethernet utilizes standard CAT5 cabling, which has a specified

maximum length of 100 meters. However, Ethernet switches which provide fiber-optic interface
can be used to extend the physical distance between units within a network.

Serial Control Port:

After initial programming and configuration, NEXIA systems may be

controlled by

RS-232 or Telnet

communications from third-party control systems such as AMX®

or Crestron®, using the Serial Control Port. Also, external devices may be controlled via the
Serial Control Port, by utilizing

Command String

blocks within the NEXIA system design.

Remote Control Bus:

The Remote Control Bus provides connection for
