RS-232 connector — One 3.5 mm,
G
3-pole captive screw connector, labeled
RS-232, for bi-directional RS-232 (±5 V)
serial control. Default baud rate is 38400.
The RS-232 port is not intended to be
used for configuring the DMP 128.
EXP port connector — One RJ-45 jack for connection to an additional DMP 128 EXP
H
port connection.
NOTE: A one foot shielded CAT 6 cable is provided for the EXP connection.
A shielded Cat 6 cable wired in a straight through configuration up to 35 feet
(10 meters) can be used.
LAN connector — An RJ-45 jack accepts a standard Ethernet cable for network
I
connection. The control system and DMP 128 must be connected to the same
network.
NOTE: To connect the DMP 128 directly to a computer Ethernet port, use a
crossover Ethernet cable.
• A yellow LED indicates data activity on the connection.
A green (Link) LED indicates the jack is connected properly to the network.

Ethernet cabling.
Reset button and LED indicator — The reset button returns the DMP 128 to
J
different tiers of default states and can place the unit into an event recording mode for
troubleshooting. When using the reset function, the LED blinks to signify the different
tiers (see DMP 128 Hardware Reset Modes
the LED operates as a power indicator, duplicating the front panel LED operation.
AT connections (AT models only) — Four RJ-45 jacks for Ethernet connection form
K
a 4-port Gigabit switch that interfaces with the AT bus. The AT port expansion bus
uses the Dante protocol for digital media networking allowing connection of multiple
DMP 128 AT models to form a larger matrix.
The AT bus supports 56 channels of audio input (Rx) per DMP 128 AT model.
Output channel support (Tx) includes the eight line outputs, eight virtual returns (post
processing), and eight expansion outputs for a total of 24 channels. Audio from an
AT port is placed on a network and the audio channels assigned to the network are
available to any Dante-compatible device on the network, such as another DMP 128 AT.
NOTE: The Dante Controller software is required for configuration of the AT
expansion bus (see
Telephone connections (P models only) — These optional connections provide
L
telephony access.
The plain old telephone system (POTS) interface provides two RJ-11 telephone jacks
to connect to the incoming phone line (LINE) and to the telephone (PHONE). The
telephone interface follows all applicable US and International standards.
ATTENTION:
• For telephone and network cabling, to reduce the risk of fire, use a minimum
conductor size of 26 AWG, UL Listed or CSA Certified Telecommunication Line
Cord.
• Concernant le câblage téléphonique et réseau, afin de réduire le risque
d'incendie, utilisez une taille de conducteur de 26 AWG minimum, listée UL ou
un cordon de ligne téléphonique certifié CSA.
