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. 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.
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.
