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.
