Front and Rear Panel Descriptions (Cortex 360)

Front Panel

The Cortex 360 front panel provides easily accessible site and equipment-status information without requiring the use of a computer.

OLED Display – Under normal operation, the display is blank to conserve power. To turn it on, push any of the four menu buttons.

Menu buttons – Four push buttons allow navigation through the different OLED menus.

POWER LED – Indicates status of the unit’s power. It is on when the unit is under rated power.

ALARM LED – Shows the Alarm status. If there is one or many alarms, the LED will be on.

COMMUNICATIONS – Shows the unit’s call-out status. It will turn on every time the unit makes an outside call (telephone, email, SNMP Trap, etc.)

USER ONLINE – Indicates if one or more users are connected to the unit.

ACTIVITY – Indicates the health status of the CPU. This “heartbeat” flashes at a rate of one (1) pulse per second when the unit is operating correctly.

PAUSE and LOCAL buttons – The PAUSE button stops transmission of Alarms to the outside, while the LOCAL button blocks outside actions and control when staff is on-site for maintenance or repair work.

Headphone jack – Provides audio for monitoring purposes. It is active when audio is applied on the unit’s rear connector audio input pins. A powered speaker can also be connected to this port.

USB port – Provides a means of connecting to the unit using a computer with the DavLink 6 software.

Ethernet ports – An embedded 4-port network switch gives networking flexibility and versatility. Along with providing IP access to the unit, these ports can also be used to connect Davicom expansion modules, networked equipment, or networked accessories. Of particular interest is the connection of on-site SNMP-enabled equipment. This switch is powered by the Cortex’s 12 VDC power which should remain active during a site power-failure.

USB ports – An embedded 4-port USB hub allows connection of USB accessories like memory sticks, a mouse, a keyboard, Davicom Expansion devices or Modbus-compatible equipment and accessories.

INPUT / OUTPUT connectors – Two 50-pin connectors provide interconnection from the unit to the outside world. They allow access to the unit’s physical inputs and outputs (Metering, Status, Relays). They also provide auxiliary supply outputs (+5 Volts and +12 Volts) for sensors and accessories. See Pinout in Appendix C.

Audio jacks – The first audio jack outputs whatever audio has been selected for audio monitoring, or the audio that will be fed to the PTT type of alarm. The second audio jack is an input and is for audio streaming over IP or via dial-up. The third audio jack is a microphone input that can be used to remotely listen to site noises such as equipment fans.

Clock input – This future option will allow connection of GPS clock-type signals for ultra-precise RTC control.

IOIOI – The IOIOI 9-pin male connector is a serial port that can be used for an external modem, for equipment reach-through, for Modbus interfacing as well as for serial backhaul communications. It can be configured for RS-232 or RS-485 operation.

Ground screw terminal – This terminal is used to connect the unit to the site’s electrical ground. It is of utmost importance to provide an excellent ground to the unit in order to avoid or limit damage caused by lightning strikes or electrical problems.

Telephone line (requires a Davicom modem installed inside the unit) – Connects the unit to a phone line for remote access by computer or by using DTMF tones. It also allows the unit to send alarm calls by modem or voice.

Power Fail (P.F.) – Monitors the presence of the main AC utility power through the use a small external AC adapter. When the voltage derived from the main AC utility power falls below a specific level, this input will change level from normal to 12 active. It can be set to trigger alarms and advise users that a power outage occurs at the site. THIS IS NOT THE UNIT’S POWER SUPPLY INPUT.

Protection fuse – 3-amp fuse protection on power supply inputs.

DC input power jacks – Redundant 4-pin XLR connectors provide power to the unit. Any one of the two inputs can be used at any time to power the unit, or both at the same time. These two power inputs allow for power redundancy. The power rating is either 12 VDC @ 3 Amps, OR 24 VDC @ 1.5 Amps, but any voltage between 10 and 30 VDC can be used. VERY IMPORTANT: Do not mix different power supplies on these inputs (for example, do not use 12 volt and 24 volt power supplies at the same time). Only use power supplies having the same output voltage.
