Digital 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).

RS-232 connector — Two stacked 3-pole 3.5 mm captive screw connectors,
labeled RS-232 (1) and RS-232 (2), are available for bi-directional RS-232 (±5 V) serial
control. Default baud rate is 38400.

LAN (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.

Reset 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).
