Installation Guide
Rio Rancho, NM 9
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.

Outputs Wiring Example
Three Programmable Inputs:
2 - 10 K linear potentiometers
for volume control
1 - Tobble switch for muting
3 Programmable Outputs:
LEDS for function indicators
(380 to 500 Ohm resistors in-line
to avoid burning out LEDS)
NOTE
Common Connections can be used for
all voltage and ground connections
among all devices.
CODEC and TEL Remote Control Ports
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.
