SNMP Appliance

Powerful & Versatile SNMP Appliance for Your Remote Site

Cortex units have a built-in SNMP Agent to allow monitoring and control from a central SNMP manager. When activated, this agent allows remote SNMP management systems to perform GETs, SETs and to receive traps from Davicom units.

A unique feature is that Cortex units also have a built-in SNMP Manager. It allows the units to take readings, set controls and receive alarms from SNMP enabled devices. This monitoring and control is achieved over a simple TCP/IP connection between devices, thus greatly facilitating interface wiring. Otherwise incompatible devices can therefore be made to “play well together” and achieve greater operational versatility for remote sites.

With its SNMP Agent and built-in SNMP Manager, Davicom’s Cortex is a dedicated SNMP appliance. As an appliance, it is not a PC running Windows® that will spontaneously decide it is time to perform a system update or crash into a blue screen. It is running an embedded Manager and Agent that continuously monitors its SNMP inputs and outputs to detect critical activity.

The Cortex’s SNMP Agent can convert analog readings or contact closures provided by legacy equipment into SNMP-compatible OID’s that can be sent to, or read by, an external SNMP Manager.



The Cortex’s Manager can take readings, make settings and receive alarms (via its built-in TRAP receiver) from other, on-site SNMP-compatible devices, and depending on the situation, it can then take action locally, or even concentrate the information from all the devices and pass it along to a remote SNMP Manager at the Networks Operations Center (NOC).



Thanks to their multiple inputs, outputs and interfaces, Cortex units can convert between different protocols and means of communications:

  • SNMP to Modbus
  • Modbus to SNMP
  • SNMP to relay outputs
  • SNMP to vocal telephone call
  • Telephone (DTMF) to SNMP
  • Telephone (PPP) to SNMP



Since Cortex units are equipped with both an SNMP Agent and an SNMP Manager they can perform a unique feat of self-control. A Cortex unit can actually change its configuration on-the-fly depending on various input conditions.

A real-life example from a customer is that they have set the Cortex to auto-disable its modem for a pre-set time, so it doesn’t answer phone calls during this period. This allows another piece of equipment at the site to answer the phone and communicate its data.
