ON CARD INSTALLATION
4.1 P RE - INSTALLATION NOTES
The user can install ISA bus or PCI bus add-on cards such as network or fieldbus cards in
the device. The card slots are accessed by taking off the back cover (only one slot in
511X). The screws on the back of the control system should be removed for this purpose.
Warning:
The components in the device are highly sensitive products, which can be destroyed or
impaired by improper handling. The same applies to the PC add-on cards to be installed.
Therefore the appropriate measures have to be implemented in all cases to avoid
electrostatic shock to the components upon contact.
4.2 N OTES ON CONFIGURING THE ADD - ON CARD (P N P)
The Ethernet and IDE controllers on the adsX board are connected via an internal PCI bus.
Therefore the addresses and IRQs are automatically assigned by the BIOS.
The following should be considered when installing or reconfiguring ISA cards:
• Install and switch on device without ISA cards and then note down the assigned IRQs
and addresses.
• Install additional ISA cards in such a way that the IRQs assigned to PCI controllers are
not used again.
• Reserve IRQs for ISA cards in the BIOS.

ON CARDS
• Switch off the device and all units connected to the PC and disconnect them from the
power supply.
• Unscrew the cover screws using a matching screwdriver and carefully remove the
cover.
Warning:
The cover may be connected to mechanical parts in the device by a grounding wire!
Do not remove the cover with force.
• Reduce electrostatic charge by implementing the appropriate measures (see above),
remove the add-on card from the packaging, place it in the slot and bolt it to the card
mount.
• Each ISA card should be fastened in the matching slot with a clamp to prevent the card
from falling out.
• Reconnect the grounding conductor if it has been removed and replace the cover while
paying attention to the side clips as the case may be.
• Tighten all of the screws on the cover again.
