4.1 Jumper Positions for I/O Address
Selection
To install the Controller it may be necessary to change
the I/O address from the factory setting of 300, for
instance, if other hardware components use this ad-
dress.
The I/O address is changed by moving a jumper on the
ISDN-Controller card, then entering the new address in
the ISDN-Controller driver software or operating system
configuration. This section describes the hardware
adjustment: moving the jumper. The procedure for
adjusting the software configuration is described for
each operating system in Chapter 3, Driver Software
Installation.
The ISDN-Controller has one jumper row containing one
jumper. To locate the jumper row, hold the board in front
of you with the component side up. The controller
sockets are at the right side, the contact fingers are at
the bottom (see illustration):

The position of the jumper determines the I/O address.
The following diagrams show the jumper settings and the
corresponding I/O addresses. To change the I/O ad-
dress, pull the jumper off and slide it onto the contacts at
the corresponding position.
