Table 16 - Problems and Error Messages

Problem/Message
When you issue the ARP –S
command in Windows, "The
ARP entry addition failed: 5"
message displays.
When you attempted to assign
an IP address to the
UDS/CoBox via the ARP
method, the "Press Enter to go
into Setup Mode" error
(described below) displayed.
Now when you Telnet to the
UDS/CoBox, the connection
fails.
When you Telnet to port 9999,
the message "Press Enter to go
into Setup Mode" displays.
However, nothing happens
when you press Enter, or your
connection is closed.
When you Telnet to port 1 to
assign an IP address to the
UDS/CoBox, the Telnet window
does not respond for a long
time.
When you try to assign an IP
with Device Installer, you get
the following message:
"No response from device!
Verify the IP, Hardware
address and Network Class.
Please try again."
UDS-10 User Guide
Reason
Your currently logged-in user
does not have the correct rights
to use this command on this PC.
When you Telnet into port 1 on
the UDS/CoBox, you are only
assigning a temporary IP
address. When you Telnet into
port 9999 and do not press Enter
quickly, the UDS/CoBox will
reboot, causing it to lose the IP
address.
You did not press Enter quickly
enough. You only have 5
seconds to press Enter before
the connection is closed.
You may have entered the
Ethernet address incorrectly with
the ARP command.
The IP address you are trying to
assign is not on your logical
subnet.
The UDS/CoBox may not be
plugged into the network
properly.
The cause is most likely one of
the following:
The Hardware address you
specified is incorrect.
The IP address you are trying to
assign is not a valid IP for your
logical subnet.
You did not choose the correct
subnet mask.
Troubleshooting
Solution
Have someone from your IT
department log you in with
sufficient rights.
Telnet back into Port 1. Wait for it
to fail, then Telnet to port 9999
again. Make sure you press Enter
quickly.
Telnet to port 9999 again, but
press Enter as soon as you see
the message "Press Enter to go
into Setup Mode."
Confirm that the Ethernet address
that you entered with the ARP
command is correct. The Ethernet
address may only include
numbers 0-9 and letters A-F. In
Windows and usually in Unix, the
segments of the Ethernet address
are separated by dashes. In some
forms of Unix, the Ethernet
address is segmented with
colons.
Confirm that your PC has an IP
address and that it is in the same
logical subnet that you are trying
to assign to the UDS/CoBox.
Make sure that the Link LED is lit.
If the Link LED is not lit, then the
UDS/CoBox is not properly
plugged into the network.
Double-check the parameters that
you specified. Tip: You cannot
assign an IP address to a
UDS/CoBox through a router.
