7: Interfaces Transmission Encoding Field Automatic Detection Preconfigured Manual Description This option uses an algorithm to try to determine what sort of connection is being used, and sets up parameters to match. These settings may change from login to login depending on the state of the network at that point. Establishes a set of parameters optimized for each of a number of connection types. The default transmission encoding is LAN (high color), which is uncompressed with a 16 bit color depth. Other data networks may be chosen from the Network speed drop-down list, and the compression and color depth will be configured accordingly. Allows the direct control of the compression factor and color depth. The simplest way to reduce bandwidth is to cut the color depth down to 8 bits; subtle color shades will be gone but the overall image is very usable. Dialing up the compression level also makes available even further reductions in color depth, all the way down to black and white (1 bit.) As compression level increases and/or color depth decreases, image quality and responsiveness to changes deteriorates but required bandwidth is reduced.

Transmission Encoding

KVM Console Type

Note:

Users have two ways to deploy the Remote Console program. Both provide the

same functionality and differ only in deployment method.

The default is Java Web Start.

Applet deployment is available in case the user cannot connect via Java Web Start. This

usually should not happen unless the user has a special proxy server or firewall that

blocks Java Web Start.

KVM Console Deployment

Miscellaneous KVM Console Settings

Field

Description

Automatic Detection

This option uses an algorithm to try to determine what sort of connection is

being used, and sets up parameters to match. These settings may change

from login to login depending on the state of the network at that point.

Preconfigured

Establishes a set of parameters optimized for each of a number of

connection types. The default transmission encoding is LAN (high color),

which is uncompressed with a 16 bit color depth. Other data networks may

be chosen from the

Network speed

drop-down list, and the compression

and color depth will be configured accordingly.

Manual

Allows the direct control of the compression factor and color depth. The

simplest way to reduce bandwidth is to cut the color depth down to 8 bits;

subtle color shades will be gone but the overall image is very usable. Dialing

up the compression level also makes available even further reductions in

color depth, all the way down to black and white (1 bit.) As compression level

increases and/or color depth decreases, image quality and responsiveness

to changes deteriorates but required bandwidth is reduced.

this user. This may be changed to interactive mode from within the Remote

Console window, if the user has appropriate permission.
