DMTH4

LECTROSONICS, INC.

Network - One or more DMTH4 devices may be made

available for network connections by connecting

them to a gateway computer system. A gateway

PC, or gateway server acts as a middleman,

receiving commands for a DMTH4 over a network

connection, and forwarding them to the DMTH4,

which is connected to it via USB. To work as a gate-

way server the PC must be a member of some local

area network (LAN) or the internet, by means of an

Ethernet connection, and be running the Lecnet2

“Net Server” program.

Extron IPL T S - One or more DMTH4 devices may be

made available for network connections by connect-

ing them to an Extron IPL T S ethernet control in-

terface. The IPL T S interface acts as a middleman,

receiving commands for a DMTH4 over a network

connection, and forwarding them to the DMTH4,

which is connected to it 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 serial port for RS-232 communica-

tions between the DMTH4 and the computer.

Note: The control panel will list any COM ports

available on the computer system.

Serial->COM2 - Same as above.

Go Ofﬂine - No Connection Made, this mode can be

used to conﬁgure the DMTH4 off line and is the

default mode.

The DMTH4 can be conﬁgured on site or a conﬁgura-

tion ﬁle can be created in advance, then downloaded

into the unit in the installation. The minimum required

setup to pass audio includes: Inputs, Matrix and Out

Source. Input and output ﬁlters and compressors are

used to tailor the system for speciﬁc audio situations.

Master/Slave Conﬁguration

When stacking multiple DM Series units, one unit is

always set as the Master and all subsequent units are

set as Slaves. The DMTH4 is normally conﬁgured as

a Slave unit and placed at the end of the DM Series

chain.

The DMTH4 leaves the factory conﬁgured as a Master

unit to facilitate initial setup. If the unit has been con-

ﬁgured as a slave, it can be temporarily set to Master

mode via the front panel MODE button. If the front

panel MODE button is used, the unit will return to Slave

Mode the next time the DMTH4 power is cycled.

Using the DMTH4 Control Panel

to Change Master/Slave Mode

Changing the Master/Slave Mode can be easily accom-

plished through the DMTH4 Control Panel.

To do this, select Connect on the DMTH4 Control Panel

Menu Bar, then click “Connect >USB” to open the

“Select Lecnet2 Device” dialogue. Highlight the DMTH4

and click “OK.”
