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.
