Product Description

The MultiConnect device server is a complete, ready to deploy serial-to-Ethernet device server for conne c ting legacy
devices to an IP network for remote monitoring, control and configuration. The MultiConnect provides a high
performance Ethernet bridge as well as a complete TCP/IP protocol stack. MultiConnect can make your existing and
next generation device, machine, or system IP-ready while you focus on developing its core features.

Serial-to-Ethernet Technology. MultiConnect provides the powerful ability to IP-enable legacy serial devices

allowing more options for data acquisition, device management, and industrial control than would otherwise be
available. The MultiConnect includes a processor, operating system, TCP/IP stack, Web server, and a network
connection to provide a complete serial-to-Ethernet bridge.

Internet-Enable Any Device. MultiConnect allows you to network-enable virtually any serial device. Using

embedded Internet protocols and a connection to an IP network, MultiConnect sends and receives data over the
Internet or Intranet connection.

Reduces Development Time. MultiConnect can make your existing and next generation serial device IP-ready

without requiring hardware changes to its design. MultiConnect actually provides faster time-to-market because it
relieves the burden and expense of writing and maintaining Internet applications. The complete, ready-to-integrate
MultiConnect device server allows you to enhance your product while you focus on deve loping its core features.

Management and Configuration. MultiConnect has several means of management and configuration built into the

design. It supports remote configuration, which means you can have central site setup and control of the remote
Adapters via the command line interface or telnet.

Chapter 2 – Installation

Attaching the MultiConnect to a Fixed
Location

The MultiConnect is design to be used on the desktop or to be panel-mounted. To attach the bracket for panel­mounting, following these steps:

1. Typically, the MultiConnect is mounted against a flat surface with two mounting screws. Drill the mounting holes
at the desired location. The mounting holes must separated by 4 - 15/16 inches center-to-center.

2. To attach the brackets to the MultiConnect, slide the mounting brackets into the corresponding slots on the back
of the MultiConnect chassis.

3. Attach the device to the surface with two screws.

Chapter 5 – Auto-Discovery Manager

Chapter 5 – Auto-Discovery Manager

Introduction

The Windows-Based Auto-Discovery Manager for the Serial-to-Ethernet
MultiConnect

The Auto-Discovery Manager is a mechanism for remotely monitoring the IPModule. It also provides support for
configuring several key parameters, such as DHCP Status (enable/disable), IP Address, and the Hostname of a
Serial-to-Ethernet Device Server.

The Auto-Discovery mechanism is utilized by running a Windows-based Server Application that can
monitor/configure the Serial-to-Ethernet Device Server. Communication between the Serial-to-Ethernet Device
Server and the Windows-based Server is through MAC level broadcasts on a configured UDP port.

Auto-Discovery Components

The Auto-Discovery Manager is composed of two components:

• The Client Component – The Client component periodically broadcasts its current configuration over

the network.

• The Server Component – The Server component receives the broadcasts from the client.

Client Component

The Auto-Discovery Client component is integrated with Serial-to-Ethernet Device Server. It broadcasts
its current configuration over the network on a specific UDP SERVER-PORT. By default the SERVER­PORT is set to 1020. The configuration parameters broadcast are

• Version details

• MAC Address

• Static IP Address

• DHCP Status

• DHCP Assig ne d IP Address

• Host Name

• Broadcast interval

• Port number on which the client listens

How to Disable the Client Auto-Discovery Broadcasts

#set auto-discovery disable

Note: By default it is enabled

How to Change the Periodic Timer of Client's Broadcast

#set auto-discovery broadcast-timer <t secs>

Note: By default it is 10 seconds.

How to Change the Server-Port

#set auto-discovery server-port <port number>

Multi-Tech Systems, Inc. Serial-to-Ethernet Device Server User Guide (S000344E) 14

Server Component

The Server component listens on the SERVER-PORT. It receives the broadcasts from the client and
updates the list of configuration parameters. This list can be viewed by the administrator through the
User Interface:

How to View the Detailed Information

New entries are appended to the list shown on the screen above. Only the first ten entries are

on an entry displays the detailed information about that entry.

How to Edit the List and Make the Changes Permanent

1. Double-click on the entry you wish to edit.

Multi-Tech Systems, Inc. Serial-to-Ethernet Device Server User Guide (S000344E) 15

Chapter 5 – Auto-Discovery Manager

Continued: How to Edit the List and Make the Changes Permanent

2. After clicking the desired entry, a new dialog box displays showing the curr ent configuration.

3. Enter the new parameters and click the SET button. The server sends the modified parameters
to the client.

Upon receiving the broadcast from the Server, the Client validates the packet. The Client
determines whether the packet is destined for its own MAC Address. If so, it sets the modified
parameters that are different from its current configuration, and it broadcasts the newly
configured parameters.

The Client Status is set to Active upon the receipt of a broadcast packet.
The Client Status is made Inactive if there is no request from the client for a stipulated period.

(3 * periodic timer value).

How to Set the Parameters to the Previous Configuration

When the RESET button is clicked, the parameters are set to the defaults received. In other words,
RESET is similar to UNDO (it sets the modifications to the previous ones).

Supported Feature – Saving the Log

The logs can be saved to a file. They are spooled into the third part of the window in the main dialog box. To save the
log:

Chapter 6 – Upgrading the Firmware and Flash

Upgrading the Flash

Serial Flash Upgrade

The following steps explain the procedure to upgrade a flash using the serial COM port (serial flash upgrade).

Connect the Device Server to a PC COM Port.

• Open an application through which we can access the serial device(e.g., Meterm, zoc, hyperterm).

• Reboot the Device Server.

• Wait for the boot message and prompt “press d to download” to appear.

• Press d when prompted.

• Select the XMODEM Protocol from the Terminal application.

• Choose a file (MTXCSEM-TFTP-…) file to be uploaded.

• Perform a file upload.

The Device Server reboots and will be up after a few seconds (10-15 secs).

Ethernet Flash Upgrade

The Device Server can be remotely upgraded over a network. Make sure a TFTP client is already installed on
the machine.

The following steps explain the method to perform flash upgrade from Ethernet.

• Make sure the Device Server is reachable on the LAN.

• Perform a TFTP to the Device Server from a TFTP client.

– Set binary mode on (Note: This step is very important)
– Binary

Appendix C – WEEE Statement (Waste Electrical & Electronic Equipment)

Appendix C – WEEE Directive (Waste

Electrical and Electronic Equipment)

Introduction

The WEEE directive places an obligation on EU-based manufacturers, distributors, retailers and importers to take­back electronics products at the end of their useful life. A sister Directive, ROHS (Restriction of Hazardous
Substances) complements the WEEE Directive by banning the presence of specific hazardous substances in the
products at the design phase. The WEEE Directive covers all Multi-Tech products imported into the EU as of August
13, 2005. EU-based manufacturers, distributors, retailers and importers are obliged to finance the costs of recovery
from municipal collection points, reuse, and recycling of specified percentages per the WEEE requirements.

Instructions for Disposal of WEEE by Users in the
European Union

The symbol shown below is on the product or on its packaging, which indicates that this product must not be
disposed of with other waste. Instead, it is the user’s responsibility to dispose of their waste equipment by handing it
over to a designated collection point for the recycling of waste electrical and electronic equipment. The separate
collection and recycling of your waste equipment at the time of disposal will help to conserve natural resources and
ensure that it is recycled in a manner that protects human health and the environment. For more information about
where you can drop off your waste equipment for recycling, please contact your local city office, your household
waste disposal service or where you purchased the product.
