!Button
The ! button enables you to recover from unsuccessful software image
downloads or other emergency situations. To start a new software image
download, press the ! button with a pointed tool or a paper clip while
powering-up the CMC. In that case, the test set will not start as usual but
wait for a new software image download.
Associate Button
The Associate button has the following functions:
• Associate with controlling computer
An Ethernet communication port enables you to communicate with any
CMC available on the network. This may lead to dangerous situations
where a user accidentally connects to a device located on a desk of
somebody else, emitting unsafe voltages and endangering the person
working there.
To prevent such a situation, a special mechanism is integrated into the
CMC test set that allows only “authorized” clients to control the test set.
By using the Associate button, the test set is registered for use with a
specific host computer. The test set will issue voltages and currents only
when it is associated to the client requesting this. The association
process can be initiated by the Test Set Association and Configuration
tool or by the OMICRON Device Browser. For more details about this
process, refer to the Help of the according tool.
For the association the Ethernet hardware address (MAC) of the
controlling computer is remembered. Consequently, if the network
interface on the computer has changed, the CMC test set has to be
associated whenever the MAC address changes.
Reset IP Configuration
If the Associate button is pressed while powering up the CMC test set,
the IP configuration of the network interfaces is reset to factory default,
which is DHCP/AutoIP for both network interfaces. It may be necessary
to reset the IP configuration in this way to recover from settings with
conflicting static IP addresses.
