2 Hardware Installation

2.1 Instructions for Various Operating

Systems

The AVM ISDN-Controller A1 can be operated on a

variety of software platforms. The exact installation

procedure for the ISDN-Controller varies according to the

operating system in question.

If you work with Windows NT, Windows 3.x or MS-DOS,

first check which I/O address is available in your PC and

change the jumper position on the Controller if necessary

(see Section 2.2). Then install the Controller and the

driver software.

A different sequence of steps is valid for installation in

Windows 95/98. See the instructions for these operat-

ing systems in Chapter 3, “Driver Software Installation”.

2.2 Adjusting the I/O Address

In order to manage and use the ISDN-Controller, the

system must communicate with it through an I/O (input/

output) address.

The default values set on the AVM ISDN-Controller A1 are

an I/O address of 300 and an interrupt (IRQ) level of 5.

If the I/O address is already being used by another

adapter, change the setting before installing the Control-

ler. The ISDN-Controller has one jumper row; the position

of the jumper determines the I/O address. The I/O

address corresponding to each jumper position is listed

in Chapter 4, “Technical Specifications”, and also is

marked beside the jumper contacts on the ISDN-Control-

ler itself. The interrupt can be changed using the A1

Setup program after completion of the software installa-

tion.
