Extron electronic DMP 64 USB Configuration Port Front Panel, Digital I/O Wiring, RS-232Wiring

EDigital I/O output connectors — A double-stacked 4-pole 3.5 mm captive screw connector provides six configurable digital input or output ports allowing connection to various devices such as motion detectors, alarms, lights, LEDs, buttons, photo (light) sensors, or temperature sensors.

Digital I/O ports are used to monitor or drive TTL level digital signals. The inputs can be configured to operate in one of two modes: digital input or digital output. In OUTPUT mode, the device can source up to 250 mA at +5 V. In INPUT mode, voltages greater than 1 V indicate a logic 'high' signal while voltages less than 1 V indicate a logic 'low'.

All digital I/O ports are tied to a common ground (one common ground for each

4-pole connector), but can be individually configured to operate in one of two modes: digital input or digital output.

NOTE: These ports can be configured via the DSP Configurator (see Digital I/O Ports on page 75 for additional information).

GLAN (RJ-45) connector — A standard RJ-45 jack accepts an RJ-45 plug for Ethernet connection.

•A yellow (ACT) LED indicates data activity on the connection.

•A green (Link) LED indicates the jack is connected properly to the network. See SIS Programming and Control on page 92 for additional information on Ethernet cabling.

HReset button — The reset button is used to return the DMP 64 to different tiers of default states and to place the unit into an event recording mode for troubleshooting (see DMP 64 Hardware Reset Modes on page 138).

USB Configuration Port (Front Panel)

A front panel configuration port uses an Extron USB A Male to USB Mini B Male Configuration Cable (part number 26-654-06) for connection to a PC computer and the USB port (see Install the USB Driver on page 17 for USB driver installation details).
