DMPA12 Installation Guide
Rio Rancho, NM 13
Initial Setup
The initial setup of a DMPA12 system is a simple four
step process:
• Set the unit to the Master mode, if necessary
• Connect the unit to the computer
• Select the signal Source
• Set the Gain / Level
LecNet2™ Software and the USB Driver must be in-
stalled before these steps can be completed.
Master/Slave Configuration
IMPORTANT: When operated as a “stand
alone” unit, the amplifier must be configured
as a Master before it will communicate with a
computer for setup.
First, connect ONLY the computer and a power cable
to the processor. Turn the power on and observe the
Status LED on the front panel. If the LED is blinking, the
unit is in the Slave mode and cannot start up because it
does not detect the presence of a Master unit.
If the STATUS LED blinks at power up, press the MODE
button to reset the unit temporarily to the Master mode.
The unit can then be connected to a computer and
configured as needed for operation.
Permanent changes to the Master/Slave status must
be made with the GUI interface. The front panel MODE
button is temporary only.
Connect
For simplicity, the instructions shown on this page
include only USB and RS-232 connections for setup
using a computer connected directly to the amplier. For
additional methods of connecting to the unit including
network and offline use, see page 17.
Connect the computer system to the DMPA12 unit us-
ing either the USB cable or the BLACK DB9 to stereo
mini (TRS 1/8”) cable for RS-232 communications.
(Both cables are included with the unit.)
NOTE: Only one DMPA12 unit at a time can be
connected to a serial port using the RS-232 cable.
Multiple units may be connected to a USB port
using a USB hub.
Turn the computer system on. After the boot sequence
is complete, click Start, then All Programs.
Select LecNet2, then select the DMPA12 control panel
from the list.
If the
“Just a Reminder” dialog appears, click OK to
continue.
Click
Connect on the Main Menu bar, then select the
type of connection between the computer system or
external control system and the DMPA12 unit.
USB - A standard interface that launches automatically
when the unit is connected and turned on. Front and
rear USB ports are provided.
Serial->COM1 - An RS-232 port for RS-232 com-
munications between the DMPA12 and the computer
sytsem, or for connecting the DMPA12 to an external
Crestron ® or AMX ® control system.
NOTE: The menu will list all serial ports detected
on the PC. However, many newer PCs have no
RS232 serial ports at all, so no serial connection
options will be listed.
For additional methods of connecting to the unit includ-
ing network and offline use, see page 18.
Connecting via a USB port.
The STATUS LED will blink if the
unit is turned on and in the Slave
mode and there is no DM Master
processor connected to it.
Use the GUI
to make
permanent
changes to the
Master/Slave
status.
