interference that may cause

undesired operation.

Controls and Features

POWER On/Off Switch

The Power On/Off Switch is used to turn the DMTH4 on

(1) or off (0).

USB Port

Standard USB connector for the setup and control of a

DMTH4 from an Windows 2000 or Windows XP com-

puter system with USB interface.

Status LED

The DMTH4 is normally configured as the end slave

unit in a DM Series stack. In this configuration, the

Status LED glows steadily when power is applied and a

Master unit has been detected. The STATUS indicator

will blink to indicate that it has not found the Master unit

or some other error exists.

Note: The DMTH4 is shipped from the factory

configured as a Master unit. In this mode, the

Status indicator glows steadily when power is

applied.

Mode Switch

If a unit configured to run in Slave mode doesn’t detect

a master unit on powerup, it will refuse to boot up and

the Status LED will blink rapidly. In this case, pressing

the Mode switch will force the unit to boot up tempo-

rarily in Master mode to allow settings to be examined

or changed. Cycling the power returns the DMTH4 to

Slave mode.

Pressing the Mode switch while powering up the

DMTH4, places the unit in Software Update mode. The

Status LED blinks slowly while the firmware is updated,

then extinguishes when the process is complete.

Cycling power exits Software Update mode.

Installing the DM system into a rack

The DMTH4 occupies a single space. There are no

special ventilation requirements. Mount with 4 rack

screws using the appropriate mounting holes. It is

recommended to use nylon washers to prevent damage

to the front panel’s finish when tightening the screws.

For North American installations, connect the Power

Cable supplied with the unit between the DMTH4 and a

stable power source. All DM processors have internal

switching power supplies that can tolerate voltages

ranging from 100 VAC to 240 VAC. Use an approved

power cable for installations outside North America.

Cables

It is recommented to use lacing bars for cable strain

relief when mounting in a rack. Use only professional

audio cable with proper shielding - typically, two con-

ductor plus ground/shield.

Audio Connections

The analog audio inputs and outputs are connected

through 5 pin de-pluggable connectors. Strip the

insulation back 1/8 to 3/16" but do not tin (apply solder

to) the leads. Insert the wire into a de-pluggable

connector, leaving less than 1 mm of bare wire ex-

posed, then tighten the retaining screw.

Caution: Do not over tighten the retaining

screw.

Note the labeling on the DMTH4 Chassis for the

positive and negative leads. Ground is shared between

two connections (the center pin).

Note: The DM Series does not have a “pin 1

problem.” Inputs and outputs are true differential

connections.

Audio Inputs (AUX and CODEC)

Unbalanced Sources

Unbalanced audio sources (positive and ground)

include items such as consumer VCR’s, DVD players,

etc., and may use both two wire and three wire cables.

In either case, the positive output from the source

should be connected to the appropriate positive (+)

input on the DMTH4. The shield or negative (–) output

should be connected the DM’s negative (–) input. Two

wire cables should have a jumper between the DMTH4

negative input and ground. Three wire cables should

have the shield connected to the DMTH4’s ground input

and the shield and negative (–) leads joined together at

the unbalanced source end.

Balanced Sources

Balanced differential sources from external equipment

and microphones should be wired according to Bal-

anced source to DM input (3-Wire). (See illustration.)

When connecting balanced sources to the DMTH4, it is

important to not connect chassis ground (shield) to

either signal conductor.

Rear Panel Ctrl tab in the Control Panel software Help

for setting all programmable input parameters.

Programmable Outputs

Programmable outputs are used to indicate the current

state of a programmable input, monitor activity on

telephone or codec interfaces, and monitor active

preset changes. 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 40 V

and they will safely conduct up to 100 mA DC continu-

ous. Following are some typical uses for the program-

mable outputs.

Audio Outputs (AUX and CODEC)

The AUX and Codec outputs are a balanced differential

configuration and include an attenuator to reduce the

signal to mic level. Wire these outputs as indicated in

the following illustration.

Telephone Line Jack

Connect a standard telephone cable with RJ11 connec-

tors between the back panel Telephone Line Jack and

the host telephone system.

Programmable Inputs

Programmable inputs are provided to enable external

control over a variety of parameters. Each input can

respond to a contact closure, a DC voltage source, or

the variable voltage output from a potentiometer. The

following illustrates common connections to the pro-

grammable input pins. (See also Programmable

Inputs and Outputs Wiring Example.)

No external pull-up resistors are necessary because

each programmable input is internally pulled up through

a 100K resistor to +5V. When using a continuous

voltage with one of the programmable inputs, the

function of the programmable input must be set to

Note: The diagram shows an external DC source

powering the relay coil. This is necessary

whenever coil voltages exceed 5 V.

Both LEDs and 5V relay coils can be powered by the +5

V DC pins on the programmable input connector, as

long as the maximum combined current for all LEDS

and relay coils does not exceed 100 mA.

Expansion I/O ports

The four RJ45 connectors on the rear panel are used to

interconnect LecNet2™ units together. These ports are

only used to transfer digital audio information via the

Digital Audio Network Interface (DANI) between the

units.

WARNING:

The Expansion I/O connectors are

NOT

Ethernet, CobraNet or any other network

based device interconnects. Connecting them

to Ethernet, CobraNet or other network based

device may cause damage to either unit.

In a stacked configuration, one unit must be configured

as the Master unit and the others as Slave units. The

DMTH4 is normally configured as the last Slave unit in

a DM Series chain.

To connect the Master/Slave units, plug one end of a 12

inch Cat5e cable (two are supplied with each with unit)

to the transmit (TX) port on the Master unit, and con-

nect the other end to the corresponding receiver (RX)

port on the Slave unit immediately below the Master.

Repeat this procedure with the second Cat5e cable.

CAUTION: Do not connect these ports to each

other on a single unit, and to not cross the

cables between the units.

Installing LecNet2™Software and USB Driver

LecNet2™ is a Graphic User Interface (GUI) designed

to allow easy setup and monitoring of DM components

using Windows®2000 or XP computer systems.

LecNet2™ includes the necessary Control Panels to

configure and monitor all the DM series products plus

the Venue Modular Receiver system.

Installing LecNet2™Software

1. Use the computer system’s 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

your system into the computer system’s CD-ROM

drive.

3. The CD should automatically start the installation

procedure. If it doesn't, click "Start" on the

WIndows Task Bar then click "Run..." Enter the

Drive number followed by "Setup.exe" then click

OK.

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 conve-

nience 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 a DM system 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

First Time Installation

When a LecNet2™ device is connected to the PC for

the very first time, the Windows Found New Hardware

Wizard automatically opens. Use the following proce-

dure to install the LecNet2™ USB driver using the

Wizard.

1. Place the LecNet2™ Installation Disk in the PC’s

CD-ROM drive.

2. On the first page of the Wizard, select the option

Install from a list or specific location (Ad-

vanced) and click Next> to continue.

3. Select "Search for the best driver in these

locations", then check "Search removable media

(floppy, CD-ROM...)" and click Next> to continue.

4. Windows searchs the CD for the driver and when it

has found it, it is likely that a dialog will open

warning you that the driver has not passed Win-

dows Logo Testing, click Continue Anyway.
