TA2020B & IR2110B Installation Guide

1 Introduction

The TA2020B and IR2110B facilitate the transmission of data over ISDN networks.

The units can be configured either by using commands entered at the serial port (much

like a modem), or via the built-in Web interface. We recommend that you use the Web

interface whenever possible.

1.1 Front Panel Features

The front panel of the unit incorporates number of LED indicators depending on the model

as shown in the following illustration (IR2110B):

Status Indicators

The status indicators operate as follows:

Illuminates steady red when power is applied.

LAN

On the IR2110B illuminates steady when there is a network

connection to the LAN port and flashes when data is transmitted

or received.

ISDN:

D, B1, B2

Flash when data is transmitted/received over the ISDN D, B1 or

B2 channels.

DTE 0, 1

Illuminate steady if a terminal is connected to the respective

serial port and the DTR signal is on. Flashes when data is

transmitted or received. DTE 1 is only present on the TA2020B.

TA2020B & IR2110B Installation Guide

Rear Panel Features

The functions of these connectors are described in the following table:

12V DC

This jack socket is used to connect the unit to the power supply

using 12V DC mains adapter.

SERIAL 0

This 25-way D socket provides a synchronous/asynchronous

RS2322 serial port which may be used to connect the unit to a

compatible serial device. The unit is supplied with a suitable 2

metre serial cable. To comply with EMC requirements it should

not be used with a longer cable.

SERIAL 1

On the TA2020B this 9-way D socket provides an asynchronous

RS2322 serial port which may be used to connect the unit to a

compatible serial device. The unit is supplied with a suitable 2

metre serial cable. To comply with EMC requirements it should

not be used with a longer cable.

On the IR2110B, this port is disabled.

LAN

On the IR2110B this socket is used to connect the unit to a

10/100-BaseT LAN using the 2-metre STP (Shielded Twisted

Pair) cable supplied or a suitable alternative. This port is auto-

sensing for speed and wiring (straight-through or cross-over). To

comply with EMC requirements it should not be used with non-

STP cable.

ISDN

This socket is used to connect the unit to an ISDN line.

Reset switch

This is located on the underside of the unit near the front. Pressing the switch gently with

the tip of a pen or other suitable implement will generate a hardware reset.

TA2020B & IR2110B Installation Guide

2 Installation

The TA2020B and IR2110B are designed for indoor use (office or home). The router

should be positioned on a smooth, level surface making sure that there is adequate

ventilation. Do not expose the router to extremes of heat or cold, strong magnetic fields or

liquids.

Step 1 –Connecting the serial cable

For connection to a serial terminal device, connect the 25-way D plug on the serial cable

provided to the SERIAL connector on the rear of the unit. Connect the other end of the

cable (9-way D socket) to the terminal. If the serial connector on the terminal is not a 9-

way D plug, you will need a suitable adapter.

Step 2 –Connecting the LAN cable (if applicable)

Plug one end of one of the supplied 2 metre CAT5 cable into the RJ45 socket labelled

LAN 0. Plug the other end into the LAN socket on your PC or notebook.

Step 3 –Connecting the power supply

Plug the jack plug on the mains adapter into the socket labelled 12V DC. When power is

first applied, the ON indicator will illuminate and the unit will initiate a series of diagnostic

self-tests. During this process one or more of the other indicators, will flash to show that

the unit is busy. When the flashing stops, the unit is ready to use.

3 Configuration

Once the TA2020B or IR2110B has be installed and powered up, you must now configure

the unit so that it can communicate with your network and the Internet.

3.1 Configuring the TA2020B

The TA2020B is configurable only through its serial port.

To access the web interface through the unit's serial port (using Windows dial-up

networking) follow the steps below.

Note: To use Dial-up Networking you must have the TCP/IP >Dial-up adapter installed in

the Network Configuration for Windows. Check this by selecting Settings >Control Panel

>Network >Configuration.

Step 1 –Installing the driver file

You will need to install the “DIGI_MULTI_PORT.INF” driver file and create a Windows

PPP Dial-up Networking connection (DUN) for the unit as described below. This driver is

available from the Digi International website (www.digi.com). It is assumed that you

already have a basic knowledge of Windows networking concepts and terminology.

The precise procedure for installing the .inf driver file for the unit will vary slightly between

different versions of Windows. The following description applies to Windows XP. Start by

selecting Start >Control Panel >Phone and Modem Options. You must be in Classic

View. Select the Modems tab and you will see a dialog similar to the following:

Click on Add… to install a new modem driver.

TA2020B & IR2110B Installation Guide

Check the Don't detect my modem, I will select it from a list option before clicking

Next > to display the following dialog screen:

This screen lists the manufacturers and models of modem currently available on your

system. Click on Have Disk….

Use the Browse button to locate the DIGI_MULTI_PORT.INF file that was downloaded

earlier. A list of routers will appear in the Models list.

Each entry in the list is the same driver, set up for a different COM port. Choose the entry

corresponding to the COM port your router is connected to, and click Next >. The wizard

will ask you which COM port you wish to install the modem on.

Select the appropriate port and click Next >, and Windows will install the driver. Once

installation is complete click Finish to return to the Phone and Modem Options dialog,

where your unit will be listed:

Click on the OK button if you are satisfied with the installation.

Note: During the installation you may receive a warning that the driver is not digitally

signed. Click on Continue Installation to install the driver.

TA2020B & IR2110B Installation Guide

Step 2 –Creating a new Dial-Up Network connection

You now need to create a new DUN connection through which you can access your unit.

If you are planning to connect the unit directly to your PC for configuration purposes,

connect it to the appropriate COM port now using a suitable serial cable.

If you wish to configure a remote unit, make sure it is connected to a suitable ISDN line

and make a note of the ISDN number.

From the Windows Start menu, select All Programs >Accessories >Communications >

New Connection Wizard. You will be presented with the New Connection Wizard

introduction screen. Click on Next > to proceed to the Network Connection Type dialog

box.

Select the Connect to the network at my workplace radio-button then click on Next >:

Select the Dial-up connection radio-button then click on Next >.

From the Select a Device dialog, select the unit you have just installed and make sure that

any other devices in the list are unchecked. Click Next >.

You must now enter a name for the connection. It is helpful to choose a name that you will

easily remember such as “My Local TA” or “TA2020B - Bristol Office”. Click Next >. The

next dialog allows you to fill in the phone number for the connection.

If the connection is being created for direct local access using a COM port, you should set

the phone number to 123. This number will be intercepted by the unit and recognised as

an attempt to connect locally.

If the connection is being created for remote access, enter the correct ISDN telephone

number (including the area code) for the remote unit.

When you have done this click Next >. The final dialog screen will confirm that the

connection has been created and includes a check box to allow you to create a shortcut

on your desktop if necessary. Click on Finish to complete the task.
