USING THE NTI MULTI-USER USB KVM SWITCH
Basic Operation
The ST-
n
X
m
-USBV-U switch enables a user or several users (with sharing enabled) to access any CPU at any time. A CPU can
be shared so that more than one user can use a CPU and work on the same project – each from their own console. Resolution is
1900x1200 with no degradation –
guaranteed
. An LCD indicates the port to which each user is attached. The ST-
n
X
m
-USBV-U
can be controlled by three methods:
•
keypad control with LCD via front panel
•
OSD control via the user input devices
•
RS-232
control
Keypad Control
The front panel keypad and LCD (see Fig. 6) display allow the user to monitor switch status and route any user to any CPU on the
switch. Along with the routing of the CPUs to the input devices the keypad and LCD allow the users to configure the RS-232
control interface. The keypad buttons perform the following functions:
Key

Display next 4 users and the CPUs they are connected to.
Display previous 4 users and the CPUs they are connected to.
MENU
The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 2400, 1200 or 300 baud and the unit
address to be set to 1 - 15. See RS-232 control on page 21.

Note: By default, the display will show all connections between CPUs and users, displaying 4 at a time, from the first to
the last, and repeating the cycle indefinitely. If the user presses either the up or down arrow to manually view
connections, the display will freeze on the chosen view. To resume the default cycle of displaying all connections, the
user must press and hold either the up or down arrow for 3 seconds, and then release it.
The following examples show various methods of routing user 3 to CPU 5. CPUs and users can be entered as a two digit number
or a one digit number followed by ENTER.
