DMP128 • Setup Guide (Continued)
f
Digital I/O connectors — Connect up to four 6-pole 3.5 mm captive screw connectors. Each
connector provides ve congurable digital input or output ports allowing connection of up to
twenty devices such as motion detectors, alarms, lights, LEDs, buttons, photo (light) sensors, and
temperature sensors.
Digital I/O ports can monitor or drive TTL level digital signals. The inputs are congured to
operate in one of two modes: digital input or digital output. In output mode, the device sources
up to 250mA at +5 V. In input mode, voltages greater than 1 V indicate a logic ‘high’ signal while
voltages less than 1 V indicate a logic 'low'.
Digital I/O ports are tied to a common ground (one common ground for each 6-pole connector).
g
Connect a control system — There are three options to connect a control system to the DMP128: LAN, RS-232, and USB
(front panel only). Extron recommends using the LAN port for conguration and remote control of the DMP128.
RS-232 — Connect the host RS-232 cable to the rear panel of the switcher (
å
) using the
provided 3-pole captive screw connector for bi-directional RS-232 (±5V) serial control. The
default baud rate is 38400. Use the wiring diagram at right.
LAN — Using a standard Ethernet cable, connect to a network via the LAN port (
ç
). The
table at right shows the default network settings. The control system and DMP128 must be
connected on the same network.
NOTE: To connect the DMP128 directly to a computer Ethernet port, use a
crossover Ethernet cable.
USB — Connect the host USB port to the front panel conguration port, (notshown), using a
USB A to mini-B cable. The USB connection is used only for conguration. Use the RS-232 or LAN port for remote control of
the DMP128.
h
EXP port connector — One RJ-45 jack for digital audio connection to an additional DMP128 using the Extron proprietary
protocol. Use the included one foot long shielded CAT6 cable to connect two DMP128 units to form a larger matrix system.
The expansion bus supports 16bi-directionalchannels of audio; eight assignable channels that are mixed from any of the
input and virtual paths, and eight channels directly connected to the virtual return path outputs. See the DMP128 User Guide
for operation details.
i
Reset button and LED indicator — The reset button returns the DMP128 to different tiers of default states and places the
unit into an event recording mode for troubleshooting. The LED ashes to signify the different tiers (see “DMP128 Hardware
Reset Modes” in the DMP128 User Guide).
j
AT ports (AT models only) — Four RJ-45 jacks form a 4-port Gigabit switch that interfaces with the ATbus. The
ATexpansion bus uses the Dante™ protocol for digital media networking allowing connection of multiple DMP128AT
models to form a larger matrix. See the DMP128 User Guide for operation details.
NOTE: The Dante Controller software is required for configuration of the AT expansion bus (see Dante Controller
Software Installation (AT models only) on the next page).
k
Telephone ports (P models only) — Two RJ-11 jacks for incoming line (LINE) and telephone (PHONE) connection.
The telephone interface follows all applicable US standards and international standards for select countries. A phone dialer is
available in the DSPCongurator control software to assist with setup and testing.
When all connections have been made, power up the input and output devices, then apply power to the DMP128.
