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.

4.4 TYPICAL CONNECTION TO DSE CONTROLLERS
This section shows how to connect DSE controllers to the gateway device.
4.4.1 ADDING THE CONTROLLER TO THE DSE892
To ensure newly added controllers are recognised by the DSE892, the following steps must be
followed. Failure to do so may result in communications failure, indicated by a RED communications
port LED.
The DSE892 is factory set to accept connection via the USB port. If this is not the port to be
used, you must configure the DSE892 for the required port as detailed elsewhere in this
document.
Remove the DC supply from the DSE892 AND the connected controller(s).
Connect the new controller to the chosen communications port.
Apply the DC supply to the controller being connected (and any other controllers in the
system).
Reapply the DSE supply to the DSE892 Gateway.
