Lectrosonics DM812 - Manual (Page 9)

DM Series Installation Guide
Rio Rancho, NM 9
In a stacked configuration, one unit must be configured
as the Master unit and the others as Slave units. Con-
figuring a unit as a Master or a Slave can be done using
the front panel LCD and controls or the Control Panel
GUI interface.
Note: In order to use the convenient Control Panel
GUI, LecNet2™ must be installed on the attached
computer system. (See Installing LecNet2™
Software and USB Driver.)
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.
(See Expansion Port Digital Audio Network Interface
Interconnection Diagram.)
CAUTION: Do not connect these ports to each
other on a single unit, and to not cross the
cables between the units.
Master/Slave Configuration
When stacking multiple units, one unit is always set as
the Master and all subsequent units are set as Slaves.
The LCD interface is used to do this.

for volume control
1 - Toggle switch for muting
3 Programmable Outputs:
LEDS for function indicators
(380 to 500 Ohm resistors in-line
to avoid burning out LEDS)
