12.5.3. THE ANALYZER DOESN’T APPEAR ON THE LAN OR INTERNET
Most problems related to internet communications via the Ethernet card option will be due to problems external
to the analyzer (e.g. bad network wiring or connections, failed routers, malfunctioning servers, etc.) However
there are several symptoms that indicate the problem may be with the Ethernet card itself.
If none of the Ethernet’s cards four status LED’s (located on the analyzer’s rear panel) is lit, it is possible
that the card is not receiving power or is suffering from a massive failure.
Under the Setup – CFG menu (refer to Section 6.5) the firmware revision of the iChip processor on the
Ethernet card
shoul
d be listed. It will appear something like:
SAMPLE iChip Rev. IL702P16 1.3
NEXT PREV EXIT
If “????”appears as the revision number, something is preventing the iChip from being initialized.
On initial start up after iChip driver is enabled the analyzer’s COMM port driver tests the iChip to determine
the baud rate at which it is set to function. This test occurs when the instrument is approximately 75%
though it’s boot-up procedure and takes about 90 seconds to complete.
This test should only occur on the initial start up of the analyzer after the Ethernet card is installed and
activated (usually at the factory). A 90 second pause at this point in its boot process every time it is
turned on could indicate that a problem exists with the iChip itself, the Ethernet card or the analyzer’s
Disk-on-Chip memory that is preventing it from holding the proper baud rate setting for the COM2 port in
memory.
