WiBox® 2100E Device Server User Guide 85
Problem/Message Reason Solution
The device server is not
communicating with the serial
device it is attached to.
The most likely reason is the
wrong serial settings were chosen.
The serial settings for the serial
device and the device server must
match. The default serial settings
for the device server 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 device server via 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.
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
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.
WiBox 2100E only:
You are using the correct serial
cable, and the WiBox 2100E
should be set up correctly, but
you are not communicating
with your device attached to
the WiBox 2100E across the
network.
If you are sure that the serial
cable is correct, then you may
not be connecting to the
correct socket of the WiBox
2100E.
Another possibility is that the
WiBox 2100E 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 WiBox 2100E by
looking at the Status LED.
If the Status LED is blinking
consistently, or is completely
off, then there is a good socket
connection.
If the Status LED is solid
green, then the socket
connection does not exist. Use
the Connect Mode option C0
for making a connection to the
WiBox 2100E from the
network. Use Connect Mode
option C1 or C5 for a
connection to the network from
the WiBox 2100E
