User select box
This selection box displays the user ID for which the values are shown and for which the
changes will take effect. You may change the settings of other users if you have the
necessary access rights.
Transmission Encoding
The Transmission Encoding setting allows changing the image-encoding algorithm that is
used to transmit the video data to the Remote Console window. It is possible to optimize
the speed of the remote screen depending on the number of users working at the same
time and the bandwidth of the connection line (Modem, ISDN, DSL, LAN, etc.).
Automatic detection
The encoding and the compression level is determined automatically from the available
bandwidth and the current content of the video image.
Pre-configured
The pre-configured settings deliver the best result because of optimized adjustment of
compression and colour depth for the indicated network speed.
Manually
Allows to adjust both compression rate and the colour depth individually. Depending on
the selected compression rate the data stream between the PS/2 IP-KVM switch and the
Remote Console will be compressed in order to save bandwidth. Since high compression
rates are very time consuming, they should not be used while several users are
accessing the PS/2 IP-KVM switch simultaneously.
The standard color depth is 16 Bit (65536 colors). The other color depths are intended for
slower network connections in order to allow a faster transmission of data. Therefore
compression level 0 (no compression) uses only 16 Bit color depth. At lower bandwidths
only 4 Bit (16 colors) and 2 Bit (4 gray scales) are recommended for typical desktop
interfaces. Photo-like pictures have best results with 4 Bit (16 gray scales). 1 Bit color
depth (black/white) should only be used for extremely slow network connections.
