5: Changing the UBox's Settings

 

 

 

 

 

Subnet Mask

A subnet mask defines the number of bits taken from the

 

 

IP address that are assigned for the host part. Enter the

 

 

subnet mask as xxx.xxx.xxx.xxx.

 

 

Example: 255.255.255.0

 

 

 

 

 

Gateway

The gateway address, or router, allows communication to

 

 

other LAN segments. The gateway address should be the

 

 

IP address of the router connected to the same LAN

 

 

segment as the unit. The gateway address must be within

 

 

the local network. Enter the gateway as xxx.xxx.xxx.xxx.

 

 

Example: 192.168.20.100.

 

 

Note: If there is no gateway on the network, use the same

 

 

IP address as the UBox or the IP address of your PC.

 

 

 

 

 

UDP Port and

These fields allow you to specify which port numbers on

 

TCP Port

which the UBox communicates. This communication

 

 

happens between the UBox hardware and software. By

 

 

default, these ports are set to 10010.

 

 

UDP Port: Change this setting to change the UDP port

 

 

number on which the UBox broadcasts. Other computers

 

 

configured to use this UDP port number will be able to see

 

 

this UBox. This setting is useful if you wish to limit the

 

 

number of people connecting to a particular UBox or if you

 

 

want to hide a UBox from other users on your network.

 

 

If you change the UBox's UDP port number, you must tell

 

 

the UBox software to “listen” to the new port. To do this,

 

 

change the local UDP port number. (See Updating Server

 

 

Access Settings on page 46.)

 

 

TCP Port: Change this setting to change the TCP port

 

 

that the UBox uses to transmit and receive USB data.

 

 

If you change the UBox's TCP port number, you must tell

 

 

the UBox software to “listen” to the new port. To do this,

 

 

change the local TCP port number. (See Updating Server

 

 

Access Settings on page 46.)

 

 

Note: Most users will not need to change the UBox's UDP

 

 

and TCP ports. However, certain firewalls may block traffic

 

 

to the default UDP and TCP ports. In these instances, you

 

 

can either change the port numbers or configure your

 

 

firewall to allow connections using UBox's configured UDP

 

 

and TCP ports.
