Problem/Message
You can ping the device server,
but not Telnet to the device
server on port 9999.
The device server appears to be
set up correctly, but you are not
communicating with your device
attached to the device server
across the network.
When connecting to the Web-
Manager within the device
server, the "No Connection With
The Device Server" message
displays.
XPort Direct+ User Guide
Reason
There may be an IP
address conflict on your
network
You are not Telneting to
port 9999.
The Telnet configuration
port (9999) is disabled
within the device server
security settings.
If you are sure that the
serial port setting is
correct, then you may
not be connecting to the
correct socket of the
device server.
Another possibility is that
the device server is not
set up correctly to make
a good socket
connection to the
network.
Your computer is not
able to connect to port
30718 (77FEh) on the
device server.
Troubleshooting
Solution
Turn the device server off and
then issue the following
commands at the DOS prompt
of your computer:
ARP -D X.X.X.X (X.X.X.X is
the IP of the device server).
PING X.X.X.X (X.X.X.X is the
IP of the device server).
If you get a response, then
there is a duplicate IP address
on the network. If you do not
get a response, use the serial
port to verify that Telnet is not
disabled.
You can check to see whether
there is a socket connection to
or from the device server by
checking the state of CP1, if it
has been configured for LED1
functionality.
If the state of CP1 is blinking
consistently, or is completely
off, then there is a good
socket connection.
If the state of CP1 is low, use
the Connect Mode option C0
for making a connection to the
device server from the
network. Use Connect Mode
option C1 or C5 for a
connection to the network
from the device server. See
the full list of Connect Mode
options in Connect Mode
page 43.
Make sure that port 30718
(77FEh) is not blocked with
any router that you are using
on the network. Also, make
sure that port 77FEh is not
disabled within the Security
settings of the device server.
