Problem/Message
Reason
Solution
You may have entered
the Ethernet address
incorrectly with the ARP
command.
Confirm that the Ethernet
address that you entered with
the ARP command is correct.
The Ethernet address may
only include numbers 0-9 and
letters A-F. In Windows and
usually in Unix, the segments
of the Ethernet address are
separated by dashes. In some
forms of Unix, the Ethernet
address is segmented with
colons.
The IP address you are
trying to assign is not on
your logical subnet.
Confirm that your PC has an
IP address and that it is in the
same logical subnet that you
are trying to assign to the
XPort Direct.
When you Telnet to port 1 to
assign an IP address to the XPort
Direct, the Telnet window does
not respond for a long time.
The XPort Direct may
not be plugged into the
network properly.
Make sure that the Link LED is
lit. If the Link LED is not lit,
then the XPort Direct is not
properly plugged into the
network.
When you try to assign an IP with
DeviceInstaller, you get the
following :
"No response from device!
Verify the IP, Hardware
Address and Network Class.
Please try again."
The cause is most likely
one of the following:
The hardware address
you specified is
incorrect.
The IP address you are
trying to assign is not a
valid IP for your logical
subnet.
You did not choose the
correct subnet mask.
Double-check the parameters
that you specified.
Note:
You cannot assign an
IP address to an XPort Direct
through a router
.
The XPort Direct is not
communicating with the serial
device to which it is attached.
The most likely reason
is the wrong serial
settings were chosen.
The serial settings for the
serial device and the XPort
Direct must match. The default
serial settings for the XPort
Direct are
RS-232
,
9600
baud,
8
character bits,
no
parity,
1
stop bit,
no
flow control.
When you try to enter the setup
mode on the XPort Direct using
the serial port, you get no
response.
The issue is most likely
something covered in
the previous problem, or
possibly, you have
Caps Lock
on.
Double-check everything in
the problem above. Confirm
that
Caps Lock
is not on.
