The Telnet configuration port (9999) is disabled within the device server security settings. 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 are sure that the serial port setting is correct, then you may not be connecting to the correct socket of the device server.

12: Troubleshooting
Problem/Message
Reason
Solution
You can ping the device server,
but not Telnet to the device
server on port 9999.
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.
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.
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.
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.
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.
When connecting to the Web
Manager within the device
server, the "No Connection
With The Device Server"
message displays.
Your computer is not
able to connect to port
30718 (77FEh) on the
device server.
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.
