Appendix E: More about how the encoder finds
the server (Visionline only)
Introduction
This appendix describes the process of how the encoder finds the server. The solution is
based on DNS (Domain Name System) as well as on announcement broadcast, which is a
proprietary implementation of zero config; see section 4.1.1 for details about zero config.
Note: For more information about setting up DNS entries etc, contact the hotel IT
department. A general description of this cannot be made in this document, since this
varies with the type of DNS server that is used.
There are three challenges when the encoder is connected to the network:
1. A new encoder must be able to find the server even if it is located on a
separate subnet.
2. The encoder must be able to locate a backup server in case the primary server
fails. The backup server is assumed to have the latest database from the
primary server.
3. The above must be fulfilled even if there are multiple Visionline servers on the
same network.
To commission encoders:
Single server - to commission encoders with DNS
Multiple servers - to commission encoders with DNS
To commission encoders without DNS
To switch to backup server
Single server - to switch to backup server with DNS
Multiple servers - to switch to backup server with DNS
To switch to backup server without DNS
