3.8. Locating server
3.8.1. Overview
If users want the Pro Series to work as a server (TCP or UDP), the host acting as a client has to know
the IP address of the Pro Series. However, under the dynamic IP address environment such as DHCP,
arbitrary IP address can be assigned to the Pro Series, which means special consideration is required
to access the current IP address of it. To tackle this problem, the Pro Series can be configured to send
its IP address information whenever it is assigned a new IP address or periodically to a specific server
called locating server. You can operate a specific host as your locating server or you can use your
client host as a locating server simultaneously.
No special library or toolkit to implement locating server is provided. You have to implement your own
application by using the protocol provided below or contact us.
3.8.2. Locating server configuration
Locating server configuration screen is shown in Figure 3-17. You have to configure locating server
IP address, locating server UDP port number and connection time interval as well as to use locating
server feature or not. Initially locating server feature is configured as “Disabled”.
