48 ULTRAVIEW REMOTE 2 INSTALLATION AND OPERATIONS MANUAL
Appendix H – Browser viewer options
When you are connecting to the UltraView Remote 2 unit using a Web browser and the VNC applet, a number of
options are available.
Click the Options… button
There are four options pages:
Encoding and color level
Auto select
When ticked, this option will examine the speed of your connection to the UltraView Remote 2
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 un-ticked.
• 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 UltraView Remote 2 unit 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.
Color level
The color level is fixed at Medium (256 colors) for almost all browsers.
Inputs

When ticked, the viewer will not send keyboard or mouse information to the UltraView Remote 2
