OPERATION

1. Power Up Sequence:

There is no separate power control for the switch. The switch derives its power when either one of the four PC's that are connected to the switch are powered up. A Power Jack marked "+5VDC IN" on the back panel of the Switch is provided in case an external power supply is needed. A separate power source may be required if the keyboard and PS/2 mouse being used draws more current than can be provided from a single PC source.

Note: Some of the new Internet keyboards on the market can draw as much as 500 ma of current. Also the new Optical PS/2 mice draw as much as 100 ma of current.

2. PC Selection:

a) Keyboard "Hot-Key" Selection (available on all models): To select an active PC, first hold down the Scroll Lock Key, then pressing and releasing the top row keyboard keys 1, 2, 3, or 4. The number keys must be released before the Scroll Lock key.

Switching takes place on the release of the Scroll Lock Key, which also rearms the keyboard selection mechanism. When selection of any of the PC's is completed, observe on the front panel of the switch that the appropriate green "SEL" indicator is on.

b) Front Panel Selection:

1) Next PC (available on Standard models only): To select another PC, press the "NEXT PC" pushbutton located on the front panel of the MegaSwitch.
2) Direct Entry (available on DE models only): To select another PC, press the "PC SELECTION" pushbutton for the appropriate PC desired.

3. Auto Scan (available on DE Models only):

Auto Scan Mode will scan all powered on PC's connected to the MegaSwitch. The Switch will stay connected to each powered on PC for 5 seconds at a time and will continue to do so until disabled. To start Auto Scan hold down the Scroll Lock Key and press and release the A key, then release Scroll Lock. Auto Scan will start on the release of the Scroll Lock key, which also rearms the keyboard selection mechanism. The first PC selected will be the lowest numbered powered PC on the Switch.

Auto Scan mode can be stopped by using the keyboard to select a PC, using the "PC SELECTION" pushbutton for the appropriate PC desired, or by the Stop Auto Scan keyboard sequence (Press and hold down Scroll Lock, then press and release the S key, and then release Scroll Lock).
