Using the ST-nXm-U-HD Switch
Basic Operation
This unit enables any user to access any CPU at any time with no restrictions or limitations. Users can even share a CPU and
work on the same project – each from their own console. Resolution is supported through 1900x1200 with no degradation –
guaranteed. A Liquid Crystal Display (LCD) on the front panel indicates the port to which the user is attached. The ST-nXm-U-HD
can be controlled by three methods, front panel keypad control with LCD, keyboard control with on-screen display (OSD), and RS-
232 interface.
Keypad Control
The front panel keypad and LCD display allow the user to monitor switch status and route any user to any CPU on the switch.
Along with the routing of the inputs to the outputs the keypad and LCD allow the users to configure the RS-232 control interface.
The keypad buttons perform the following functions:
Key Action
ESC Escape back to the main display.
0 – 9 Used to enter numbers. (n )
USR The output user number can be entered (2 digits or 1 digit and ENTER)
followed by the desired CPU to be connected to.
CPU Used following single digit user entries.
ENTER Used following single digit entries.
 Display next 4 users and the CPUs they are connected to. (See note below.)
 Display previous 4 users and the CPUs they are connected to. (See note below.)
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 17.
* Activate Memory Function- 10 memory locations (0 – 9), 0 is the power ON default.
to Save current connections * - USR - n (0-9) - ENTER
to Recall connections * - CPU - n (0-9) - ENTER
The following examples show various methods of routing user 3 to CPU 5. Users and CPUs can be entered as a two digit number
or a one digit number followed by ENTER.
USR - 3 - CPU - 5 - ENTER
USR - 3 - ENTER - 5 - ENTER
USR - 0 - 3 - 0 - 5
0 - 3 - 0 - 5
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.
