3. Using the AdderView
This section explains the general operation of the AdderView. We recommend that
you read this section before starting to use the product.
3.1 Power on status
At power on the AdderView selects computer number 1 and displays '1' on the front
panel numerical display.
3.2 Front panel key
The front panel key is used to select which channel (1 to 4) is currently connected to
the user ports (coloured green on the rear panel) and which is currently controlled by
the shared keyboard, mouse and monitor. Pressing the key during normal operation
will cause the next computer channel to be selected.
Depending on the position of option switch 8, pressing the front panel key will either
select the next active computer channel or the next computer channel in numerical
sequence (1,2,3,4,1,2,3 etc.).
Using the front panel key you may cycle through the available computer channels
until you find the required port. When the AdderView detects that no new key
presses have occurred for a second it will start the channel lock-on process. During
the lock-on process the display will flash to indicate that the AdderView is currently
waiting for the enumeration guard period (see section 2.4.1). The channel may not
be changed again until this process is complete and the display stops flashing.
The front panel key may be used to select autoscan mode. Autoscan mode is
activated by holding the key down for more than 5 seconds until the display starts to
show a rotating segment. Autoscan mode may be cancelled by pressing the front
panel key whilst within autoscan mode.
