User Guide Manual
e  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 250mA 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 page75 for additional information).

f  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 (±5V) serial 
control. Default baud rate is 38400.

g  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 page92 for additional information on 
Ethernet cabling.
h  Reset button — The reset button is used to return the DMP64 to different tiers of 
default states and to place the unit into an event recording mode for troubleshooting 
(see DMP64 Hardware Reset Modes on page138).
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 page17 for USB driver installation details).
