Network testing and troubleshooting
1
If the GEN series is connected to the Ethernet correctly, the LINK LED on
the front panel will illuminate within a few seconds to indicate that a
hardware interface has been detected. If the LINK LED does not illuminate,
the Ethernet cable is not connected or is wired incorrectly (straight instead
of cross
-
over or vice versa). Hold the two ends of the cable side by side
with the retainer tab facing downward. A straight cable has orange wires
on the left
-
hand side at both ends. A crossover cable has orange wires on
opposite sides. Also check that all eight conductors are present in the
connector. Some inexpensive cables contain only four conductors. These
cables are not compatible with the GEN series.

If the LINK LED is illuminated but the Perception software cannot find the
GEN series system, check the TCP/IP network settings on the GEN series
and on the PC. On the Windows PC, select Start in the task bar, click Run…
and type "CMD" (without quotation marks). This opens a command window.
In the command window type, IPCONFIG or IPCONFIG /ALL to view
settings. Some of the most common problems are:
l
IP addresses that are not in the same range. Normally, the first three
octets are the same and the fourth one varies, such as 169.254.10.252
and 169.254.10.200.
l
Identical IP addresses. The PC and the GEN series must have at least
one different digit in the fourth octet.
l
IP addresses that use the reserved numbers 0 or 255. All digits should
be between 1 and 254.
l
The subnet masks are not completely identical.
