English Manual

Special Configuration

For many installations, no further configuration will be required once the host system and user consoles are connected. This chapter covers the various special configuration options that may be required in certain cases.

Configuration switches

The LINDY Console Switch front panel features a set of eight mini switches which are used to determine a number of options:

Action	Switch
Power source selection	1
Video signal boost	2
Reset LINDY Console Switch	3
Enter configuration mode	6
Enter upgrade mode at power on	7

Note 1: Switches 4, 5 and 8 are reserved for future use.

Note 2: When changing switch positions the LINDY Console Switch can be powered on or off.

Power source selection (switch 1)

This switch determines how the LINDY Console Switch derives its power.

OFF	Draw power only from the power adapter.
ON	Draw power from power adapter, if present, or alternatively use power from the host
	system keyboard port.

Note 3: The LINDY Console Switch is fitted with an auto-resettable fuse rated at 500mA. If the total power drawn by the connected keyboards and mice is approaching, or exceeds 400mA, then the power adapter must be used.

Note 4: The power adapter must be used if the LINDY Console Switch is to be cascaded with other similar units or interface-powered KVM switches or extenders.

Video signal boost (switch 2)

This switch selects video boost mode which gently amplifies the video signal and is particularly useful for improving picture quality when long video cable lengths are used.

OFF	No video boost
ON	Apply video boost
