Live results using ZViewer

Using ZViewer to follow up live results over internet is not the recommended way. You can still use it on large installations to publish information along several places over LAN.

You will see next a diagram of how ZRound/ZViewer work.

ZRound has the possibility of transmitting real time data to ZViewer by checking the “Activate Service” option in the “Remote” configuration page. You can use the TCP Port you want, by default 5000 is used. You must “open” the port used on your router/firewall to allow ZViewer clients to connect. If your PC has a LAN connection to reach internet through a router, you must enable NAT on the router to redirect the TCP Port ZRound traffic to the ZRound LAN IP address.

The connection is done peer to peer from ZViewer to ZRound, you don’t need any other server, only an TCP/IP (LAN or WAN) connection between them as you see on the picture. To prevent too many users trying to connect your server ZRound allows you to limit the amount of concurrent connection by using the “Max connections” option into the Remote configuration page.

If you have a domain registered, may by your DNS provider let you use dynamic IP for your domains. This is done by installing a little piece of software which updates the DNS entry with the public IP address that you have everytime.

At home, the users only need to know what is the public IP address (or server name resolved by a DNS) which grants the connection to ZRound and which port you are using. To start remote session you must use the File/Connect to ZRound menu …

Then you must write the ZRound server name and port with the sintax: “server : port”. If you only write “server”, the TCP default port (5000) will be used.

You can upload a ZRound Track Definition (generated with ZRound Track Desginer) to your website and ZViewer will simulate race on the track design.

In the example, ZViewer will connect to zround.myserver.com and it will download the track design from http://www.zround.com/track.zts.txt
