C2G 22391 One-Console KVM Switches - Manual (Page 14)

26
Operation
On power up, the KNV2108D and KNV2116D are in Idle mode
broadcasting VGA signal from the selected computer and detecting
for keyboard and mouse activity. User LEDs (marked with reverse
white
A
and
B
) are both red indicating the KVM Switch is not in use.
When keyboard or mouse activity is detected at one CONSOLE, the
KVM Switch immediately disables the other CONSOLE from
accessing the computer. Only one User LED, at the front panel,
remains lit indicating the KVM Switch is under user operation. In
the mean time, keyboard LEDs (Num/Caps/Scroll Lock) of the other
CONSOLE start to flash as its access is denied and the monitor is
blocked from VGA signal for security reason. After the user has
finished his operation for a period of time (i.e., User Timeout), the
multi-access KVM Switch returns to Idle mode. User Timeout has
four options, 5 sec, 30 sec, 60 sec and HOLD. Select HOLD when
you plan to access the KVM Switch for a long time. Pressing the
<Scroll Lock> twice forces the KVM Switch return to Idle mode
immediately regardless of the User Timeout setting.
The User Timeout is available in the OSD menu by pressing the
Function key <F4>, under the sub-menu More. Note: Keyboard
Speed option is not available for multi-access models.
Configuration
To expand the number of computers under control, you may connect
CONSOLE port of another KVM Switch to "PC 1" ~ "PC 8" port.
Refer to the chapter Cascade Configuration for more detail. There
are rules to apply for Master/Slave configuration. When KNV2108D
is a Master, its slave includes KNV104, KNV104D, KNV108 and
KNV108D. When KNV2116D is a Master, its slave includes all the
above and KNV116D. These multi-access KVM Switches already
come with OSD menu, their Slaves do not have to be OSD equipped.
