DMP 64 Plus • Installation
5
AT ports (AT models only)
on page 4)— Two RJ-45 ports form
a Gigabit switch that interfaces with the AT bus. The AT expansion bus uses Dante
®
protocol for digital audio networking and allows DMP 64 Plus AT models to connect
with other Dante-enabled devices to form a larger matrix (see
page 21 for details on the software required to configure the AT expansion bus).
The 2-port switch can be configured as two primary and secondary ports for redundant
Dante configurations. In redundant configuration, audio traffic is duplicated. Port 1
is the primary port (PRI) and Port 2 is the secondary switch (SEC) (see
on page 27 for details on configuring the DMP 64 Plus in redundant
mode).
NOTE:
Connecting an external power supply is not necessary when using PoE+ for
power.
ACP port
— Use a 4-pole 3.5 mm captive screw connector to connect an ACP control
device for configuration (see figure 3 for wiring details and
page 17 for details on configuring the ACP).
NOTES:
•
The DMP 64 Plus rear-panel ACP port provides 6 W of power.
•
Use an Extron PS 1220EB power supply or Extron 12 V desktop power supply
when additional power is required.
•
Refer to the applicable Audio Control Panel (ACP) setup guides, available at
www.extron.com
, for wiring details.

RS-232 port
— For bidirectional RS-232 (±5V) serial control of the DMP, connect a
host device, such as a computer or control system, via the 3-pole 3.5mm captive screw
port. The default baud rate is 38400.

LAN (Ethernet) ports
— One RJ-45 port (non-V models) or two RJ-45 ports (V
models) are available for control network traffic (all models) and VolP network traffic
(V models only) (see
TP Cable Termination for Ethernet Communication
page 11 for wiring details). The host PC or control system and the DMP 64 Plus must
be connected to the same network. The ports have two LEDs:
•
Link LED
— Lights green steadily to indicate a LAN connection.
•
Signal LED
— Blinks amber to indicate LAN signal activity.
NOTE:
Only the DMP 64 Plus V-models have two LAN/VoIP ports. Non-V-models
only have one LAN port.
