CMC 356 Reference Manual

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.
5.2.5 Status LED A, B
The status LED A and B are of interest in case of troubleshooting.
A : yellow status LED
• A lit yellow LED indicates that the test set is ready to be controlled by a
computer. The hardware checks in the test set are finished, and the test
set is properly connected to a computer or a network.
• The LED is off when the test set is waiting for an "emergency software
image download". This is the case when pressing the ! button while
powering-up the CMC test set.
B : green LED
If the yellow LED A is off, the green LED B signals the following conditions:
• LED B blinks slowly: CMC test set waits for the TFTP download ( T rivial
F ile T ransfer P rotocol) of a software image.
• LED B is lit: The TFTP download of the software image is in progress.
• LED B blinks quickly: The computer writes, e.g., the software image to
the flash memory of the CMC test set. Do not turn off the CMC test set as
long as the writing is in progress.
