Installation Specific Information Only
This guide covers only installation related matters. See the Reference Guide additional details and explanations of the DM Series digital processors.
Unpack the unit and inspect the contents
Included in the box:
Reference Manual
Power cable
5-pin de-pluggable connectors:
20 each for the DM1624 14 each for the DM1612 10 each for the DM812
CAT-5e cables (2 each) 12" with shielded RJ45 connectors
Lectrosonics screwdriver
DB9 to TRS (Stereo mini) cable – BLACK - for laptop setup
DB9 to TRS (Stereo mini) cable – RED - for touch panel control systems
USB cable
CD-ROM with LecNet2 software and documentation in Acrobat PDF files
Remove all packaging and make certain all the above materials are enclosed in the box. If not, IMMEDIATELY call 1-800-821-1121 to report the missing components so we can get any needed replacements on their way to you. Ask for anyone in sales or service.
Installing the hardware into the rack
The DM1624 and DM1612 occupy two rack spaces. The DM812 occupies a single space. There are no special ventilation requirements. Mount with 4 rack screws in the appropriate mounting holes – We recom­mend using nylon washers to prevent damage to the finish when tightening the screws.
Power is connected via the included IEC power cable. DM processors have internal switching power supplies that can tolerate voltages from 100-240VAC. Use an approved power cable for installations outside the United States.
Cabling
We recommend using lacing bars for strain relief when mounting in a rack. Use professional audio cable with proper shielding - two conductor plus ground/shield.
Audio connections
The analog audio inputs and outputs are connected through 5 pin de-pluggable connectors. Strip the
insulation back only 1/8 to 3/16" and do not tin (apply solder to) the leads.
When tightening the connector do not over tighten and do not leave more than 1mm of exposed wire beyond the edge of the connector.
Note the labeling on the unit for the positive and nega­tive leads. Ground is shared between two connections (the center pin). For balanced connections, all three leads can be connected.
The DM1624 does not have a “pin 1 problem”.
Unbalanced and balanced input connections use the following guidelines.

Audio Outputs
All outputs are a balanced differential configuration. Some outputs include an attenuator to reduce the signal to mic level. Wiring is the same for either line or mic level, as indicated in the following illustrations.
NOTE:
USING A LINE OUTPUT WITH THE DIGITAL ATTENUATION
APPLIED WITH THE CONTROL PANEL TO ACHIEVE MIC
LEVEL WILL RESULT IN ADDED NOISE
Use the outputs marked as MIC/LINE OUTPUTS for mic level applications. Using the other outputs marked LINE OUTPUTS with control panel attenuation can result in up to 40 dB off additional noise.
When the DM output is connected to a balanced input, wire it as indicated in this illustration.
Select Mic or Line either from the front panel LCD interface or via the software GUI.

Programmable Inputs
Programmable inputs are provided to enable control over a variety of parameters. Each input can respond to either a contact closure or a continuous voltage. The diagram below shows common connections to the programmable input pins.
Each programmable input is internally pulled up through a 100K resistor to +5V, so no external pull up resistors
are necessary. When using a continuous voltage with one of the programmable inputs, the Function of the programmable input must be set to either Analog In Control or Analog Out Control on the Programmable Inputs control tab in the GUI. See the Programmable Input tab in the Control Panel software for setting all programmable input parameters.

Programmable Outputs
Programmable outputs are used to indicate either channel activity or the current state of a programmable input. Each programmable output is the electrical equivalent of a contact closure to ground. When a programmable output is “active”, it conducts current to ground. When the programmable output is “inactive”, no current flows to ground. The maximum usable voltage for the programmable outputs is 40V, and they will safely conduct up to 100mADC continuous. The diagram on the right shows some typical uses for the program­mable outputs.

It is permissible to run LEDs from the +5VDC pins on the programmable input connector, as long as the total LED current for all LEDS on does not exceed 100mA. Similarly, 5V relay coils may also be run from the +5VDC pins on the programmable input/output connec­tor, as long as the total coil current for all relays on does not exceed 100mA. Note that the diagram shows an external DC source powering the relay coil. This will be necessary if coil voltages above 5V are needed.

SLAVE
Expansion I/O ports
The four RJ45 connectors on the rear panel are strictly for interconnecting LecNet2 units together and are NOT EtherNet, CobraNet or any other network based device interconnects.
In a stacked configuration, one unit must be configured as the Master and the others as Slaves. This can be done with the front panel LCD or the GUI interface (after it is installed).
The transmit (TX) port from the bottom row of connec­tors on the Master connects to the RX on the top row of the first Slave unit below it. The RX port from the bottom row on the Master unit connects to the TX port on the top row of the Slave below it. Connect them only as shown.
DO NOT CONNECT THESE PORTS TO EACH OTHER ON A
Master/slave Configuration
When stacking multiple units, one unit is set as Master and subsequent units are all set as Slaves. The LCD interface is normally used to do this. Refer to the Reference Guide LCD instructions for details on config­uring units for stacking.
Control system interconnections
If connecting to a serial control system such as a CrestronTM or AMX® system use the RED TRS (tip ring sleeve or stereo mini) to DB9 cable.

DO NOT CROSS THE CABLES BETWEEN UNITS!
IMPORTANT! – DO NOT USE THE BLACK CABLE for

Initial Setup
Connect your computer using either the BLACK DB9 to stereo mini (TRS 1/8”) cable for RS-232 communica­tions OR the USB cable for USB control. Multiple units may be connected using a USB hub (available at most electronic or office supply retailers). Both cables are included with the unit.
Select Start.
Select LecNet2.
Select DM1624 Control Panel.
The control panel will start with a connection reminder.
Click on OK.
Select CONNECT on the banner menu at the top of the control panel screen.
Select the type of connection you are using. Your choices are COM ports (serial), Network, USB or Extron IPL T S.
Upon connection you will be able to program and setup the DM1624. See the help files in the software for more complete instructions.
HINT 1 - The GUI interface is quite intuitive. As a recommended first step, we suggest you select Labels from the Menu Bar and type in all the input and output labels. This will simplify further setup steps because you will be able to easily keep track of which input or output you are adjusting.
HINT 2 - The right click is powerful in this interface. You can activate quick access to a number of setup func­tions (for example - right click in any input box in the INPUTS tab ). It also allows some powerful cut and paste capabilities - especially in the matrix setup and the filter (both input and output).
Hint 3 - Presets will take about 4 seconds to switch due to the many parameters in the unit - audio will switch off temporarily during a preset switch to avoid feedback. If you need quicker response with no interruption to the audio, use macros instead - try using the macro re­corder for making any changes. The only changes that cannot be made in a macro are filter adjustments such as EQ.

IMPORTANT
The minimum required setup is necessary before the DM processor will pass audio:
Inputs Setup - Matrix Setup - Outputs Setup
The minimum setup can also be accomplished using the front panel LCD interface.
IMPORTANT - ANY CHANGES MADE DURING SETUP MUST
BE SAVED IN THE UNIT VIA THE PRESET MENU!!!
The software control panel will default to the “Offline” mode. If a DM Series unit is connected to the computer, you will need to make a connection using the control panel as shown here.
Click on Preset, then click on “STORE SETTINGS TO DEVICE MEMORY AS... “, then select the preset where you you would like to store the settings you have created. You can also set that preset as the default, so when the unit powers up, it goes to that preset.
Do this after any changes are made (not before).

Installing LecNet2™ Software
1. Use the computer control panel to remove
any previously installed versions of LecNet2 software. (This will ensure you are using the latest release.)
2. Insert the LecNet2 program disk supplied with the Venue Receiver into the CD-ROM drive on the computer system that will be used to set up and control the Venue Receiver.
3. The CD should automatically start the installation procedure. If it doesn't, click "Start" on the WIndows Task Bar then click

2. On the first page of the Wizard, select the option Install from a list or specific
"Run..." Enter the Drive number followed by "Setup.exe" as shown below.
4. Follow the on-screen instructions to install the LecNet2 software.
Installing the LecNet2™ USB Driver
There are two methods of connecting a Windows®­based computer system to the DM component, either via a USB cable or an RS-232 cable. Although the USB port offers significantly increased speed and conve­nience over standard RS-232 links, it does require the installation of a LecNet2™ USB driver.
The LecNet2 USB driver is not part of the standard Windows® 2000 and XP driver libraries. As a result, connecting a computer system to the DM for the first time is different than subsequent installations. There are a few minor differences between installing the LecNet2 USB drivers on a Windows 2000 versus a Windows XP system.
USB driver installation Windows XP
When the DM is connected to a Windows XP computer system for the very first time, the Windows® "New Hardware Found Wizard" automatically opens.

Installation additional units (or Lecnet 2 devices)
The Windows XP operating system regards all Lecnet2 devices as separate USB devices because each has a unique serial number. Because of this, Windows XP will want to install the USB driver every time it encounters a Lecnet 2 device whose serial number it does not recognize. However, if the Lecnet 2 USB driver has already been installed at least once before on the computer system, the process is simplified because the Lecnet 2 installation disk is not required. Use the following procedure if the LecNet 2 USB driver was previously installed on the computer system.
1. On the first page of the Wizard, select Install the software automatically (Recommended) and click Next> to continue.
