Installing the DMP 44 LC1. 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 c above (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 d above (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.

z 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 flow control (see the wiring diagram on the right).

z Config port (front panel) — Connect a USB cable (USB-A to Mini-B) between a USB port on your computer and this port (a on the front panel illustration shown on the right).

6. Digital input connector. Up to three configurable input ports (see f on 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.
