NTI UNIMUX SINGLE-USER HIGH DENSITY VGA USB KVM SWITCH

When switching to a new port the port name is displayed by OSD in the left upper corner of the monitor for 5 seconds or until a key is pressed or the mouse is moved, whichever comes first. The scan dwell time is programmable from 2 to 255 seconds (default time-out period is 5 seconds). While using the mouse, keyboard or touchscreen the scanned port becomes active and scanning is stopped. The switch will resume scanning after a period of user inactivity determined by the scan dwell time. See Settings Menu on page 15 for configuring the scan dwell time.

To return to the Settings menu, press <Esc>. The scan selection list is automatically saved.

Note: The scan dwell time set by the user only affects that user and has no effect on other switch users.

Note: The keyboard, mouse and touchscreen must remain idle for the full scan dwell time before the switch selects the next active port.

Broadcast Mode

To activate or deactivate Broadcast Mode press <B> from the Command Mode menu. The text shown in the menu

(Figure 11) will toggle between “BCast=N” and “BCast=Y”, each time the <B> key is pressed. When “BCast=Y” is shown, Broadcast Mode is active. When “BCast=N” is shown, Broadcast Mode is OFF.

Broadcast Mode enables the user to type characters to more computers simultaneously. From the Settings menu (see page 15) press <B> to access the “Broadcast List” where the user can edit the list of ports that receive data in Broadcast Mode.

The “Broadcast List” is a check list with all the port numbers displayed

•unchecked box = the corresponding port is not in the broadcast list

• checked box = the corresponding port is in the broadcast list

From the “Broadcast List” the user can:

•select all ports to be broadcasted to (press <A>)

•deselect all ports so that none are broadcasted to (press <N>)

•select only a limited number of ports to be broadcasted to

•find a specific port to either select or deselect (press <F> ,

then any alphabetical or numeric character to locate the desired port).

Figure 17- Broadcast List

A port doesn’t receive broadcast data if one of the following conditions is true:

-the port is not in the Broadcast List

-Security Mode is enabled and the user does not have access rights to the port

Note: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the <Backspace> key.

Note: The mouse and touchscreen will be disabled while in Broadcast Mode.

To return to the Settings menu, press <Esc>. The broadcast selection list is automatically saved.

Normal Mode

When the UNIMUX switch is not in Command, Scan, or Broadcast mode and the OSD control is not active on the monitor, the user is in Normal Mode, controlling the CPU to which the user is connected through the UNIMUX switch.
