 Introduction

2 INTRODUCTION
This document details the installation requirements of the DSE855 USB to Ethernet Convertor. 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

DSE855 USB to Ethernet Convertor is used to give Modbus TCP connectivity to a number of DSE’s
range of USB enabled controllers. A list of compatible modules is included elsewhere in this manual.

This allows connection of supported controllers to external Modbus TCP Master devices in many
ways. A non-exhaustive list is given below.

• Connection over Ethernet to DSE Configuration Suite PC Software for configuration and
monitoring.
• Connection over Ethernet to third party Building Management Systems (BMS) with Modbus
TCP Master support.
• Connection over Ethernet to third party PLCs / HMIs with Modbus TCP Master support.

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

Operator Level Sets the level of access for the user.
The Operator Level of Admin cannot be changed.

A built in Admin account is provided (Factory set password: Password1234). The password is
changeable when logged into the account however the Operator Level for this account cannot be
changed.

The Admin account has full access to all features of the DE855 and is also able to create, edit and
remove user accounts.

Each user account has three possible access levels that allow or deny access to specific functions of
the DSE855 and the USB connected controller.

When granted the correct Operator Level, the functions perform the following actions:

Function Description
Monitor Allows the user to access the SCADA page of the DSE855 to monitor the
attached DSE module and to monitor the status of the DSE855.
Control Allows the user to access the SCADA page of the DSE855 to control the
attached DSE module (ie to use the ‘Control buttons’ in the SCADA page).
Configure Allows the user to change the settings in the DSE855.
Manage Other Users Allows the user to add new users, change existing users’ passwords and
delete existing users.
Change Own Password Allows the user to manage their own password.

 Utilising the DSE855

6 UTILISING THE DSE855

6.1.1 CONNECTING USING DSE CONFIGURATION SUITE PC SOFTWARE

To connect to a module via Ethernet, select the comport from the Connect Via list, for example:

Then click TCP/IP Settings to configure the Ethernet Port:

You must consult your network administrator for help in selecting
these settings.
They must match the settings in the DSE855 Lan configuration
page that you wish to communicate with.

Parameter Description
IP Addresss IP V4 address of the DSE855 you wish to communicate with.
IP Port TCP Port number that the DSE855 is configured to use.

DSE Configuration Suite is now correctly configured to communicate with the DSE Controller
connected to the DSE855 USB port.

For information in regards to setting up the DSE controller connected to the DSE855 USB port, refer
to the relevant Configuration Suite PC Software Manual which can be found on our website:
www.deepseaplc.com.

6.2 CONNECTING USING A THIRD PARTY MODBUS MASTER

The DSE855 Ethernet port is a modbus RTU Slave. The Modbus Master must be configured to
communicate with the DSE855 using the settings entered on the Lan configuration page.
Modbus queries from the master are received by this port, and relayed to the DSE controller
connected to the USB port.
This controller replies to the query which is received by the DSE855’s USB port, and returned back to
the Modbus RTU master by the DSE855’s Ethernet port.

The host DSE controller has addressable registers as defined in the DSEGencomm Document.
This and other DSEGencomm training documents are available from DSE Technical Support upon
request from support@deepseaplc.com.
