1 INTRODUCTION

This document details the installation requirements of the DSE892 SNMP Gateway. The manual

forms part of the product and should be kept for the entire life of the product. If the product is passed

or supplied to another party, ensure that this document is passed to them for reference purposes.

This is not a controlled document. You will not be automatically informed of updates. Any future

updates of this document will be included on the DSE website at www.deepseaplc.com

DSE892 SNMP Gateway is used to connect with an SNMP V2c Community Based system to give

monitoring and control functionality.

DSE892 SNMP Gateway communicates to the connected controller(s), monitoring the instrumentation

and operating state. If this data changes, SNMP TRAP information is generated and sent to the

SNMP Manager. Additionally emails can be configured to be set to one or two email addresses.

DSE892 SNMP Gateway also supports GET functionality to read information from the host controller

and SET functionality to allow the SNMP manager to mimic button presses on the host controller.

Additionally, DSE892 SNMP Gateway contains a protocol conversion function.

For details on configuring the ‘host controller’ you are referred to the relevant configuration software

manual.

2 SNMP

Simple Network Management Protocol (SNMP) is an internet standard protocol for managing devices

on IP networks. It is used to monitor network-attached devices for conditions that warrant

administrative attention.

An administrative computer (SNMP manager) monitors one or more DSE892 devices.

Each DSE892 monitors a number of DSE controllers using a variety of connection methods (detailed

elsewhere in this manual).

Should an ‘event’ occur, the DSE892 Gateway reports information via SNMP TRAP messages to the

manager.

Additionally, the DSE892 responds to GET / SET messages from the SNMP manager to allow the

host controller’s operating mode to be changed, or instrumentation values to be retrieved.

Many third party SNMP managers exist. DSE do not produce or supply SNMP managers.

2.1 PRINCIPLE OF SNMP COMMUNICATION

2.2 MIB FILE

SNMP does not specify the type of information and functions supported by the DSE892. This

information is contained in the Management Information Base (MIB) file.

NOTE: DSE Stock a 2m (2yds) Ethernet Cable –Part number 016-137. Alternatively they

can be purchased from any good PC or IT store.

As the Gateway is autosensing, either a ‘straight through’ or ‘crossover’ cable can be used.

The diagram above shows a ‘straight though’ cable.

For the advanced

Engineer, this cable

has both ends

terminated as T568A

(as shown below) or

T568B.
