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 AdderView Prism front panel features a set of
eight mini switches which are used to determine a
number of options:

Note 1: Switches 4, 5 and 8 are reserved for future use.
Note 2: When changing switch positions the Prism can be powered on or off.
Power source selection (switch 1)
This switch determines how the AdderView Prism derives its power.
OFF Draw power only from the power adaptor.
ON Draw power from power adaptor, if present, or alternatively use power
from the host system keyboard port.
Note 3: The AdderView Prism 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 adaptor must be used.
Note 4: The power adaptor must be used if the AdderView Prism 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
Reset AdderView Prism (switch 3)
Use this option to reset the AdderView Prism. Change the switch to the ON
position momentarily and then OFF again to achieve the reset.
OFF Normal operation.
ON Reset AdderView Prism (change back to OFF position to complete the
reset).
Enter configuration mode (switch 6)
Allows you to alter key aspects of AdderView Prism operation. Within
configuration mode you can use any connected keyboard to enter specific
key combinations. See
Using configuration options
for a full list of key
combinations.
OFF Normal operation.
ON Enter configuration mode (change back to OFF once configuration options
have been entered).
Enter upgrade mode at power on (switch 7)
Places the AdderView Prism into a special state whereby you can rewrite its
internal operating software. After placing this switch into its ON position, you
need to cycle the power input or briefly use switch 3 to reset the AdderView
Prism. See
AdderView Prism software upgrade
for full details about the
upgrade procedure.
OFF Normal operation.
ON Enter upgrade mode following the next reset or power on.
