How to Set-Up the Cortex Unit

Rack mounting the Unit

The Cortex 360 unit can easily be rack-mounted with the supplied rack-mount brackets and screws. Just install the brackets on the side of the unit by selecting the mounting holes that match with your rack-rail position.

The Cortex 320 can be installed in the equipment rack by using the Davicom Rackmount Tray (P/N DRMT-01), sold separately.

Power Requirements

Specifications Cortex 320Cortex 360*
Operating Voltage 12 Vdc10 to 30 Vdc
Current consumption Typically 200 mA
(275 mA with all relays energized)
Typically 300 mA @ 12 Vdc

*The Cortex 360 features a dual-input system that allows for power supply redundancy: two power supplies can be connected at the same time in order to provide automatic fail-over switching in case one of the power supplies fails.

The Cortex uses a 4-pin XLR connector for the power supply: male on the Cortex and female on the power supply side.

Connecting the Power Supply Unit

If you did not purchase your PSU from Davicom, you will want to make your own supply cable with the XLR pigtail supplied with your Cortex unit. The pinout is indicated directly on the back panel (Pin 1: GND, Pin 4: +V).


Once power is applied to the Cortex, the unit takes about 50 seconds to boot-up and be ready. During this period, the Cortex 360 front panel display will be blank most of the time, but “DAVICOM” will appear about 40 seconds in, and then the display will go blank again.  About 15 to 20 seconds after the Cortex is powered, the 3 blue LED’s will light at the same time for a few seconds.  The unit is ready once the “ACTIVITY” heartbeat light starts blinking.
