connector ( ). 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).
Config port (front panel) — Connect a USB cable (USB-A to

a
port ( on the front panel illustration shown on the right).
Digital input connector. Up to three
configurable input ports (see
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).
Reset button. The recessed reset button is used to access various modes of resets. The
6.
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.
