Problem/Message
Reason
Solution
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.
