Hardware Installation
2. Hardware Installation
2.1 Before Starting Hardware Installation
During the hardware installation it may be necessary to change the PC/104-I/O-port address. The
default address is
0x1E0...0x1E7
. The CAN module covers 8 data bytes. Furthermore it is
necessary to set the interrupt during the following software installation.
Make sure that there will be no address conflict with other boards of the PC/104-systems
and that there will be no conflict with other interrupts!
Windows NT/2000/XP Users:
In order to avoid address and interrupt conflicts, the used address ranges should be checked
before starting the hardware installation.
This can be done in Windows NT 4.0 e.g. by selecting
Programs
/
Administrative Tools (Common)
/
Windows NT Diagnostics
. In the dialogue box
Windows NT Diagnostics
call
Resources
and there
select
I/O Port
. A list with the used and available address ranges appears.
Make sure that the default value of the CAN-PC104/331 is in a free memory area. If it is not, note
one free memory area (which corresponds to the choices stated in fig. 2.2.2) and change the
CAN-PC104/331 address by means of the coding switch during the hardware installation
described below.
In the same dialogue box call
Interrupts
. A list with the used interrupt lines appears. Note a free
interrupt, because you have to select an interrupt for the CAN module during the software
installation. (The complete
software
installation sequence is described in the software manual
‘NTCAN-API, Part 2: Installation Guide’.)
Windows 9x/ME Users:
If you use a Windows 9x/ME operating system
first read the software installation guide
in the
appendix of the manual ‘NTCAN API, Part 2: Installation Guide’ and then start with the installation
sequence!
