TruLink™ 4-Port USB 2.0 and PS2 KVM Switch
10
4. Operation
The
KVM Switch supports three methods to switch between computers:
Pushbutton
,
Hot Keys,
and
OSD
. Due to the refresh of the video and re-synchronization of the
mouse and keyboard signal, it can take up to 3 seconds before control is re-established
after switching to ensure proper signal synchronization.
Note for users with connected USB devices (other than keyboard/mouse):
The drivers for most USB devices (Mass Storage device, CCD Cameras, Scanners,
Card Reader, Printers, e.g.) require the device to be disabled before you disconnect
the device. Follow the “
Safely Remove
” process provided in Windows before you
disconnect the device to avoid system freezes or other problems. When you switch
computers via the KVM, it is the equivalent of disconnecting the device. Therefore, if
you have peripheral devices (other than a second keyboard and mouse) connected to
these ports, you must be sure to shut down or safely remove the USB driver for them
before switching computers.
1. Manual Switch by pushbutton:
You can switch to any other available active USB host connection by simply pushing
the appropriate switch button on the
KVM Switch. The LED will be lit to indicate
which port is currently selected.
2. Two Step Hot Key Switch by PS/2 keyboard:
You can switch to any available PC by entering a two step Hot Keys sequence directly
from the PS/2 keyboard. To send commands to the
KVM Switch, [Scroll] must be
pressed twice (Step 1). Then you can press [1] to [4] (Step 2) to switch between ports.
Note: Hot keys are supported by
PS/2 Keyboard only. USB keyboard users must use
manual switch method or OSD.
*After invoking the Hot Key function with the [Scroll] , [Scroll] , you must press
the corresponding final command (Step 2) within 3 seconds for each key press.
(The Scroll Lock LED on the keyboard will start blinking and wait for the final
command. After completing the hot key sequence or 3 seconds have elapsed, the
keyboard LED will revert back to its original state.)
