Figure 1: Jumper locations
The base address is set with jumper bank J1.
The possible selections are listed in figure 2.
Jumper bank J2 determines the used interrupt
channel. The settings can be seen in figure 3
(IRQ 5 is set as an example). It is not allowed
to set more than one jumper on this bank.
Jumper J3 (optional) allows to supply + 12V
from the PC to the CAN on CPC-XTI card
configurations without galvanic decoupling. J3
may only be set if no other device supplies the
CAN power line and the PC has enough
capability on its +12V line. This feature does
not provide protections against overvoltage,
overload, short circuit or other error conditions.
The use of this option is in the resposibility of
the user.
