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
congure and control the DMP via Simple Instruction Set (SIS™)
commands.
• RS-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 ow control (see the
wiring diagram on the right).
• Config 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).
Digital input connector. Up to three
congurable 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).
6. 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.
7. Connect power to the DMP 44 LC by connecting the included 12 VDC external power supply
to the rear panel power connector (see a in the rear panel diagram). The wiring diagram is
shown on the right.
