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 Port – Provides IP access to the unit. Expansion modules can also be added to the CORTEX 320 by connecting this port to an external Ethernet switch (sold separately).

USB ports – An embedded 2-port USB hub allows connection of USB accessories like memory sticks, Davicom Expansion devices or Modbus-compatible equipment and accessories.

INPUT / OUTPUT connectors – Two 25-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). One of the connectors also provides auxiliary supply outputs (+5 Volts and +12 Volts) for sensors and accessories.

Audio jack – The audio jack can be configured as an input (line-in) or output (line-out) using on-board jumpers inside the unit.

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 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 input.

DC input power jack – An XLR connector provides power to the unit. The power rating is either 12 VDC @ 3 Amps, but any voltage between 10 and 15 VDC can be used.
