23 – Output Channel Function Indicators

Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the DC-One, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two adjacent LED are displayed to indicate all possible output bandpasses. (Full range is indicated by no lit LED’s.)

24- A.C. Inlet

The DC-One features a standard IEC A.C. inlet that will accept universal power cords. The DC-One power supply is auto-ranging and can accept voltages from 100 - 240VAC, 50 – 60Hz. Only A.C. cords approved for use in your country should be connected to the DC-One.

25 – A.C. Fuse

The A.C. inlet includes a fuse holder that contains the mains fuse as well as a spare fuse. If necessary, replace the fuse only with a specified 5x20mm, T800mA, L250V replacement. Disconnect A.C. power before replacing a fuse. Before turning the unit back on, assess the condition of the A.C. receptacle powering the DC-One. If fuses continue to blow, refer servicing of the DC-One only to qualified service personnel.

26 – A.C. Power Switch

The A.C. power switch turns power to the DC-One On and Off.

27 – Link/Relay Interface

The operating mode of this dual purpose interface is selected in the Setup menu. Operating modes are:

RS-232 Interface – Used to link two DC-Ones together in a Master / Slave setup. Connection is made via a standard 9-pin null-modem serial interface cable with female connectors.

Contact Closure Port – Eight contact closure pins plus ground for interfacing to 5v contact closure systems. Each pin can be assigned a preset that is recalled when voltage on that pin is detected. The lowest pin number takes priority in multiple controller systems.
