6 MTASR2-201
Introduction
Welcome to Multi-Tech's new DSU RouteFinder, Model MTASR2-201, which provides secure and
seamless LAN-to-LAN routing capability and can also provide dial-up capability. This unit
supports multiple WAN services and supports a wide range of routing protocols including IP, IPX,
TCP, and RIP version 2. When the WAN 2 port is configured to support it, this unit also supports
a secondary capability of dial-up Remote Access Server (RAS) access for telecommuters and
mobile users from any Point-to-Point Protocol (PPP) or Serial Line Internet Protocol (SLIP)
networking client. Refer to the Chapter 4, DSU RouteFinder Software, and your on-line help
system for more details on RAS.
The DSU RouteFinder features a 10Base-T port for local LAN connection, a command port for
configuration, a 56K bps DDS 4-wire WAN connection, and an RS232/V.35 port for an optional
Data Communications Equipment (DCE) device (i.e., external modem, T1/E1 CSU/DSU, etc.).
System management is provided through the command port using bundled Windows®based
software which provides easy-to-use configuration menus.

Preview of this Guide
This guide describes the DSU RouteFinder and tells you how to install and configure the unit.
The information contained in each chapter is as follows:
Chapter 1 - Introduction and Description
Chapter 1 describes the DSU RouteFinder. Front panel indicators, and back panel connector
descriptions are provided. In addition, a list of relevant specifications is provided at the end of the
chapter.
Chapter 2 - Installation
Chapter 2 provides information on unpacking and cabling your DSU RouteFinder. The installation
procedure describes each cable connection and shows how to switch the shunt position if the
unit is to be used with V.35.
Chapter 3 - Software Loading and Configuration
Chapter 3 provides instructions for software loading and initial configuration. The DSU
RouteFinder software disks are Windows® based. Later chapters, and your on-line help program,
describe the DSU RouteFinder software in greater detail.
Chapter 4 - DSU RouteFinder Software
Chapter 4 describes the DSU RouteFinder software package designed for the Windows®
environment. This chapter describes the DSU RouteFinder software from an applications
standpoint, and in so doing, not every screen is shown, nor is each field within a screen defined.
For explanations and parameters of each field within a dialog box, refer to the on-line help
system provided within the software.
Chapter 5 - Remote Configuration and Management
Chapter 5 provides procedures for changing the configuration of a remote DSU RouteFinder.
Remote configuration enables you to change the configuration of a unit by simply connecting two
modems between the two DSU RouteFinders and remotely controlling the unit. Chapter 5 also
describes typical client applications (i.e., Telnet and Web-based management) used for remote
configuration of the DSU RouteFinder.
Chapter 6 - Warranty, Service and Tech Support
Chapter 6 provides instructions on getting service for your DSU RouteFinder at the factory, a
statement of the limited warranty, information about our Internet presence and user bulletin board
service, and space for recording information about your DSU RouteFinder prior to calling Multi-
Tech’s Technical Support group.

Front Panel Description
The front panel, shown in Figure 1-2, contains four groups of LEDs that provide the status of the
Ethernet connection, 56K DSU port, WAN port, and general status of the DSU RouteFinder. The
Ethernet LEDs indicate the status of the LAN activity, the 56K DSU LEDs indicate the status of
the internal DSU port (WAN 1), and the WAN Link LEDs indicate the status of the external DCE
device (WAN 2). There are also two LEDs which indicate whether the self test passed or failed
(Fail) and if the power On/Off switch on the back of the DSU RouteFinder is turned On (Power).

RS232/V.35 Connector
The RS232/V.35 (DB-25) connector is used to connect the DSU RouteFinder to an external
modem, DSU, or other Data Communications Equipment (DCE). This connection can be either
RS232C (default) or V.35. If the connection is V.35, then the shunt must be moved from the
default RS232 position to the V.35 position (for details on this procedure, refer to Chapter 2 - V.35
Shunt Procedure).
56K DSU Connector
The 56K DSU connector is used to connect the DSU RouteFinder to a Digital Data Service
(DDS) network connection. This connector is an RJ-45 jack.
10Base-T (Ethernet) Connector
The Ethernet 10Base-T connector is used to connect the DSU RouteFinder to a LAN using
unshielded twisted cable. This connector is an RJ-45 jack.
Command Connector
The Command connector is used to configure the DSU RouteFinder using a PC with an available
COM port and running Windows® software. The Command port connector is an RJ-45 jack and
an adapter cable is provided to plug into a standard 9-pin COM port on a PC.
Power Connector
The Power connector is used to connect the external power supply to the DSU RouteFinder. The
Power connector is a 6-pin circular DIN connector. Aseparate power cord is connected to the
power supply and the liveAC grounded outlet.

V.35 Shunt Procedure
If you are using an external DCE device on the WAN 2 RS232/V.35 port, and the connection will
be a V.35 connection, the internal shunt must be moved from the RS232C (default) position prior
to cabling and power-up. The following steps detail the procedures for switching the shunt.
Step Procedure
1 Ensure that the external power supply is disconnected from the DSU RouteFinder.
2 Turn the DSU RouteFinder over and remove the cabinet mounting screw (Figure 2-3) from
the chassis.

The following steps detail the procedures for connecting the cables to your DSU RouteFinder.
1. Connect one end of the power supply to a liveAC outlet and connect the other end to the
DSU RouteFinder as shown in Figure 2-5. The power connector is a 6-pin circular DIN
connector.
2. Connect the DSU RouteFinder to a PC using the RJ-45 to DB-9 (female) cable provided with
your unit. Plug the RJ-45 end of the cable into the Command port of the DSU RouteFinder
and the other end into the PC’s COM port. See Figure 2-5.
3. Connect a network cable to the ETHERNET 10BASET connector on the back panel of the
DSU RouteFinder. Connect the other end of the cable to your network.
4. Connect one end of an RJ-45 cable to the 56K DSU connector on the back of the DSU
RouteFinder. Connect the other end to your Digital Data Service (DDS) WAN connection.
5. If you plan to use the optional RS232 port for dial backup, connect one end of an RS232
cable to the RS232/V.35 connector on the back panel of the DSU RouteFinder and connect
the other end of the cable to an external DCE device such as a modem or T1/E1 CSU/DSU.
6. Turn on power to the DSU RouteFinder by setting the ON/OFF switch to the ON position.
Wait for the FAIL LED on the DSU RouteFinder to go OFF before proceeding. This may take
a couple of minutes to go OFF.
At this time your DSU RouteFinder is completely cabled. Proceed to Chapter 3 - Software
