How to Handle the Card
Take these precautions to guard against ESD damage:
•
Touch a grounded object to discharge any built-up static.
•
Do not touch the connector or connector pins on the card.
•
When not in use, store the card in the anti-static packaging in which it was
shipped.
Set the Node Address
You must set two switch assemblies to configure the daughtercard with its unique
network address. Figure 1 (next page) shows the location of the switches. These
switches are read on powerup to establish the network address of the card.
Set the node address to a value between 1 and 99. For optimum throughput, assign
addresses to your ControlNet nodes in a sequential order starting with 01.
Node address 00 is not a valid ControlNet address. You should only use node
address 00 if the product that uses the ControlNet daughtercard has the ability to set
the node address using the host device interface.
This feature is typically used on products that do not provide easy customer access
to the node address switches. If you set the node address switch to 00, it lets the
host in which the daughtercard resides set the node address, rather than letting the
daughtercard read the node address from the switch settings.
ATTENTION
ÿ
The card uses CMOS technology, which is highly sensitive to
electrostatic discharge (ESD). ESD may be present whenever you
are handling the card. Handling the card without any ESD
protection can cause internal circuit damage that may not be
apparent during installation or initial use.
