Appendix 4 - Browser viewer options
When you are connecting to the CPU IP using a Web browser, a number of options are available.
Click here to access the options 
There is a single page of options:
Encoding and colour level
Auto select
When ticked, this option will examine the speed of your connection to the CPU IP and apply the most suitable encoding method. This option is suggested for the majority of installations.
Preferred encoding
There are three manually selectable encoding methods which are accessible when the Auto select option is unticked.
•ZRLE – This is a highly compressed method that is best suited to slow modem connections.
•Hextile – This method offers better performance than the ZRLE when used over a high speed network because there is no need for the CPU
IP to spend time highly compressing the data.
•Raw – This is a primitive, uncompressed method that is mainly used for technical support issues. You are recommended not to use this method.
Colour level
The colour level is fixed at Medium (256 colours) for almost all browsers.
