Colour/Encoding
Auto select
When ticked, this option will
examine the speed of your
connection to the AdderLink IP
Gold 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 AdderLink IP Gold 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.
Appendix 2 - VNC viewer connection options
When you are connecting to the
AdderLink IP Gold using the VNC
viewer, a number of options are
available.
There are six tabbed pages of
options:
Colour level
This section allows you to select the most appropriate colour level for the speed
of the connection to the AdderLink IP Gold. Where the connection speed is slow
or inconsistent there will be a necessary compromise between screen response
and colour depth.
• Full – This mode is suitable only for fast network connections and will pass
on the maximum colour depth being used by the host system.
• Medium (256 colours) – This mode reduces the host system output
toa256colourmodeandismoresuitableforISDNandfastmodem
connections.
• Low (64 colours) – This mode is suitable for slower modem connections
andreducesthehostsystemoutputto64colours.
• Very low (8 colours) – This mode provides very rudimentary picture

recommended not to use this mode.
IMPORTANT: If you make any changes to the options given here and wish to
retain them for successive connection sessions, you must save the changes.
To do this, change to the ‘Defaults’ tab and click the ‘Save as defaults’ button.
