using the Extron Expansion Bus with DMP 128 at Devices

A DMP 128P AT model can be connected to a non-AT model by the Expansion (EXP)
ports with the following exceptions:

Two AT models cannot be connected together using their EXP ports.

AT models are always the primary unit. The non-AT model must be set as the
secondary unit.

The sixteen EXP outputs from the non-AT secondary unit connect to the AT primary
unit at inputs 41 through 56.

The secondary DMP 128 or DMP 128 C EXP inputs are routed as they normally
would be.

DMP 128 AT devices are set as the Primary unit by default. This setting cannot be
changed because the expansion bus primary and secondary selections in Device Settings
are not available on AT models (see

Dante Network Audio Setup

on page 113). When

an AT device is connected to a non-AT device by the Expansion port, the non-AT device
must be set as the secondary unit.

to configure Expansion port connectivity using a DMP 128 at:

1.

Power on both units. Open DSP Configurator and connect Live to the non-AT

model DMP 128.

2.

From the menu, select Tools > Expansion Bus > Secondary
Unit.

3.

Connect the DMP 128P AT EXP port to the non-AT model DMP 128
EXP port using the included shielded one foot CAT 6 or similar
CAT 6 cable. When connectivity is established, the front panel EXP
LED on the primary unit (AT) lights solid and the EXP LED on the
secondary unit blinks.
In DSP Configurator, EXP bus channels appear as EXP Inputs
41 through 56 on AT models, and 1 through 16 on non-AT models.

notE: When two non-AT models are connected, channels received on the

Expansion bus appear as Expansion Inputs 1 through 16.

Configuration of the EXP channels can be done at this time. You can also add additional
AT models to the digital audio network. Always make the Expansion port connection
between the two units before adding AT units to the digital audio network (see

Dante

Network Audio Setup

on page 113).

notE: The Dante Controller software is required for configuration of the AT expansion

bus (see

Dante Controller Software Installation

on page 113).

When connected to a non-AT device, all 56 receive channels of the DMP 128 AT still
appear on the Dante digital audio network. However, Expansion inputs 41 through 56 are
connected to the secondary (non-AT) device by the EXP bus, and are not operational on
the Dante audio network.

Viewing at channels with at Meters

The AT meters allow the user to see the signal levels of any attached Dante device. See

view

on page 22 for information on accessing the meters.

A connected Dante device is selected and all active transmit and receive channel real-time
signal levels for that device are monitored.
