Initial Setup
The initial setup of a DM84 system is a relatively simple
three step process: connect the unit to the computer,
turn on the computer and select the appropriate control
panel, preset the input, matrix and output. This process
assumes that LecNet2™ and, if necessary, the USB
driver have been previously installed. If they have not
been installed, please refer to Installing LecNet2™
Software and USB Driver.
1) Connect the computer system to the DM84 unit us-
ingeithertheBLACKDB9tostereomini(TRS1/8”)
cable for RS-232 communications or the USB cable
for USB control. (Both cables are included with the
unit.)
NOTE: Only one DM84 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.
2) Turn the computer system on. After the boot se-
quence is complete, click Start, then All Programs.
3) Select LecNet2, then select the DM84 control panel
from the list.
5) If the “Just a Reminder” dialog appears, click OK
to continue.
6) Click Connection on the Main Menu bar, then
select the type of connection between the computer
system or external control system and the DM84
unit.
The choices are:
USB - used when the computer is connected
to the DM84 unit via the front or rear
panel USB port.
Network - One or more DM84 devices may be
made available for network connections
by connecting them to a gateway server
acting as a middleman, receiving
commands for a DM84 over a network
connection, and forwarding them to the
DM84 device connected via USB.
Extron IPL T S - One or more DM84 devices
may be made available for network
connections by connecting them to
an Extron IPL T S ethernet control
interface. The IPL T S interface acts as
a middleman, receiving commands for a
DM84 device over a network connection,
and forwarding them to the device via an
RS232 port. To work as a gateway server
the IPL T S interface must be a member
of some local area network (LAN) or
the Internet, by means of an Ethernet
connection.
Serial->COM1 - An RS-232 port for RS-232
communications between the DM84 and
the computer sytsem, or for connecting
the DM84 to an external control system
such as those made by Crestron
®
or
AMX
®
.
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.
 GoOfine-NoConnectionMade,thismode
can be used for off line configuration and
is the default mode.
