Installing the DMP 44 LC

1. Disconnect power from all equipment.

2. (Optional) Mount the unit to a rack or furniture.

3. Connect the audio input. Connect up to four balanced or

unbalanced mono line level input devices to line input

connectors cabove (see the wiring diagram on the right).

4. Connect the audio output. For balanced or unbalanced

audio output, connect up to four output devices to line output

connectors dabove (see the wiring diagram on the right).

5. Connect a control device. Connect a host device, such as a

computer, to one of the following DMP 44 LC ports to

conﬁgure and control the DMP via Simple Instruction Set (SIS™)

commands.

zRS-232 port (rear panel) — Connect a host device

to the Tx, Rx, and _(ground) pins of this 6-pole

captive screw connector (e). The default baud rate

for this port is 38400 baud, 1 stop bit, no parity,

8 data bits, and no ﬂow control (see the wiring diagram

on the right).

zCong port (front panel) — Connect a USB cable (USB-A to

Mini-B) between a USB port on your computer and this

port (aon the front panel illustration shown on the right).

6. Digital input connector. Up to three

conﬁgurable input ports (see fon the

rear panel diagram) allow connection

to various digital devices including

motion detectors, alarms, buttons,

photo (light) sensors, and temperature

sensors. This connector shares a

ground pin with the RS-232 connector (see the wiring diagram above).

Both the RS-232 and digital input connectors may be used simultaneously by using

a 6-pin captive screw connector with two wires sharing the same ground connector

(see the diagram on the right).

7. Reset button. The recessed reset button is used to access various modes of

resets. The green power LEDs on both the front and rear panels indicate

the reset mode that was accessed. The reset modes are detailed in the user guide.
