First Steps

Give it some power

First, give your device the power it needs through the power supply unit!

Onto the net

Connect the unit to your local network using the twisted pair cable. Please check the position of the node/hub switch: 'Node' is the correct position when connecting the unit to a network. Switch to 'Hub' when connecting the unit directly to a workstation.

The wire to the world

Connect the ELSA MicroLink Cable to the TV cable network using the coaxial cable or the adapter and a normal antenna cable. Data is transmitted through the cable TV network in accordance with the MCNS (Multimedia Cable Network System)/DOCSIS standard.

The connection to the cable TV network must provide a certain signal level. This value will be checked by your cable network operator and adjusted as required.

And we're off

Switch the device on at the back. The 'Power' LED on the front panel lights up after a short self-test. The 'LAN Link' LED indicates that the unit is correctly connected to the LAN and that the Node/Hub switch is correctly set.

If this LED is not lit, change the position of the Node/Hub switch. If the LED still does not light up, there may be a problem with the network adapter or the cabling.

Software installation

The ELSA LANconfig configuration software for Windows 95, Windows 98 or Windows NT 4.0 may be used to configure the unit as required or to set it up for other applications. Alternatively, you can perform the configuration via telnet from any other TCP/IP capable computer (e.g. Linux, Solaris). Install the TCP/IP network protocol, followed by the ELSA LANconfig on the computer that will be used to set up the device. If the setup program does not start up automatically after insertion of the CD, start Windows Explorer, click on 'autorun.exe' on the ELSA MicroLink Cable and follow the instructions in the install program.

Configuring the ELSA MicroLink Cable

The first time ELSA LANconfig is run, the new modem is automatically detected on the TCP/IP network and can immediately be configured.

When configuring the router with ELSA LANconfig, you can use the setup wizards to quickly and conveniently guide you through the required settings.
