UsingUsingthe STthe-nXmST-U-HDnXmSwitch-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	CPU:	1	2	3	4
							ESC	USR	6	7	8	9	0
0 - 3 - 0 - 5		USR:	1	2	3	4
							MENU	CPU	1	2	3	4	5

ENTER

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.
