Trap Relay 64 Overview

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

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 to legacy alarm systems, operating visual/audible notification systems, and rebooting jammed equipment.

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

  1. Granular mode: Allows the user to configure each relay to operate or release based on the enterprise, generic-trap, and specific-trap information of a SNMP v1 trap or the trap OID of a SNMP v2c trap.
  2. Cisco-VMS mode: The unit will ignore each relay's SNMP trap configuration and will momentarily operate relays when it receivers either a 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 mode created just for you.

Trap 48RA.

Trap 48RA - Medium Capacity Option.

The Trap 48RA is a device that operates up to 48 relays and 16 audio outputs using received SNMP trap information. Currently there are two supported trap processing modes of operation. Granular mode allows the user to configure each relay to operate or release based on the enterprise, generic-trap, and specific-trap information of a SNMP v1 trap or the trap OID of a SNMP v2c trap. Each SNMP trap can also be defined by an optional variable binding. In Cisco-VMS mode, the unit will ignore each relay's SNMP trap configuration and will momentarily operate relays when it receives either a mediaStreamDeviceUnreachable, mediaStreamConnectionLoss, or mediaStreamConfigFailure VMS 6.3 SNMP Trap. A relay in Cisco-VMS mode will only operate if its description matches the VMS trap's mediaStreamName value. This telco-grade remote is housed in a durable aluminum chassis that will require the use of two standard rack units for mounting.
