Note the following hints on changing the default I/O base address of
dSPACE boards:
n The I/O address ranges of dSPACE boards in your system must not
overlap. If your expansion box is connected via Ethernet, this
applies also to the address ranges of the slot CPU and the
FlashDisk.
n There are other devices like network boards or SCSI controllers
using the same I/O address range.
This does not apply if the expansion box is connected to the PC via
Ethernet or via the link boards DS815, DS817, DS819, DS821 and
DS814. In this case, only the link boards (PC) need resources in the
PC. These resources are assigned automatically by the link boards’
plug & play feature.
n If you want to install the DS1103 in an expansion box, the plug &
play circuit on the DS1103 must be disabled. This is done
automatically, when the board’s I/O base address is set to an
address other than “000H”.
n Suppose you have connected several expansion boxes to your host
PC via one of the link boards (PC) DS815, DS817, DS819 or
DS821, or via a MultiLink Panel DS830. If two (or more) of these
boxes contain a dSPACE board of the same type, you have to set
them to different I/O base addresses to allow the identification in
ControlDesk Next Generation.
n
Within an Ethernet multiconnect group, the I/O base addresses of
all included dSPACE boards must be unique.
For detailed instructions on changing the I/O base address, refer to

How to Change I/O Base Addresses
The I/O base address, meaning the port address, is selected via three
rotary switches on the DS1103.

Before you check and change this address, you should first read the
basic information in Basics on Changing I/O Base Addresses
