UBox User Guide 54

Status Condition Suggestions

Is Not Listed The UBox software cannot

find the UBox hardware. 1. Verify that the UBox software's local UDP

port is set to match the UDP port used by

the UBox hardware. The default is 10010.

(See Updating Server Access Settings on

page 46.

2. If you do not know the UDP port that your

UBox software is using, set the Local

UDP Port to 10010.

3. If this does not work, reset your UBox

hardware (see page 55).

4. If you still cannot see your UBox, proceed

to Troubleshooting: Network Issues

below.

Is Listed This is normal and indicates

that the UBox hardware is

working.

Troubleshooting: Network Issues

Communication Between your PC and the UBox

If you have determined via the status LEDs that the UBox is communicating with a

specific network, but network communication between the computer and the UBox is

not established, you can ping the UBox from the PC trying to communicate with the

UBox:

To ping the UBox:

1. From the Windows Start menu, select Run, type cmd, and click OK.

A command window opens.

2. At the prompt, type ping xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is the

IP address of the UBox). If the UBox replies, the physical and logical (IP subnet)

network communications are good. Proceed to step 4.

3. If you do not receive a reply from the ping, the problem is network related. Make

sure:

 IP addresses of the PC and UBox are on different subnets

 Physical network connections of the PC and UBox are established:

− Check network cable connections.

− Verify that switches/hubs are powered up.

− Verify that you have a network link light on the PC and UBox.

Note: Some Ethernet hubs/switches may not properly route UDP and

TCP traffic when connected to other hubs and switches. This is

especially true when your UBox is using Zeroconfig to obtain an IP

address. To avoid these issues, connect your UBox and your computer

to the same Ethernet hub/switch.
