Trap Relay 64

Mediate and process inbound SNMP traps with the Trap Relay 64.

Key Features

  • 64 control relay outputs
  • 64 ping targets
  • Easy-to-use web interface

The Trap Relay provides a cost-effective and critical way to link inbound SNMP traps with a relay output. This device is the first of its kind from DPS. Typically, SNMP traps are forwarded from an RTU to an SNMP Manager. This device will receive inbound SNMP traps and use this information to operate or release one of the device's control relays. Traps received by the Trap Relay can be identified by either IP address, Trap ID, or by an additional variable binding.

With the 64 relays, you'll be able to remotely control any device that you normally operate with a button or a switch. The relays will latch or release a contact closure based on the commands it receives. Relays are perfect for turning on small devices, opening doors, interfacing with legacy alarm systems, operating visual/audible notification systems, and rebooting jammed equipment.

The Trap Relay RTUs can be operated in one of two modes:

  • Granular mode
    Allows the user to configure each relay to operate or release based on the enterprise, generic-trap, and specific-trap information of an SNMP v1 trap or the trap OID of an SNMP v2c trap.
  • Cisco-VMS mode
    The unit will ignore each relay's SNMP trap configuration and will momentarily operate relays when it receivers either one of several VMS 6.3 SNMP Traps. A relay in Cisco-VMS mode will only operate if its description matches the VMS trap's mediaStreamName value.

If you have a specific device you want the Trap Relay to interface with, contact the engineers at DPS to have a specific device created just for you.
