A 2.1 mm jack accepts 12 VDC power for the unit from the power supply provided
with the unit (SBE, Model No. SP1805A). The center must be positive, and the
nominal current consumption is 300 mA, but the supply must be capable of
providing 12 VDC @ 0.5 A.

RS485 serial data is provided at this terminal block and is used to control Pan Tilt
Zoom (PTZ) cameras. The PTZ protocol and serial port settings are configured
via the web interface.

devices. The contacts are closed when active and are rated for 12V at 200 mA.
Future releases of the DVM system will be able to control this output.

A single digital input is provided at the terminal block to accept control signals
from an external device such as a door bell. The input is active when the two
