Model VSM-404

3. Operation

3.1 The Switch’s LEDs

The LEDs on the 4 x 4 Video Matrix Switch’s front panel indicate which of

the Switch’s outputs are displaying the video from which inputs.

3.2 Switching with the Keypad

To switch a given output to display a given input (or

to blank an output), press “[out][.][in][Enter]” on the

Switch’s keypad, where:

• [out] is the number of the output channel (1 through 4, or “*” for all

outputs);

• [.] is the keypad’s decimal-point/Delete key;

• [in] is the number of the input channel (1 through 4, or 0 to blank the

output); and

• [Enter] is the keypad’s Enter key.

For example, to display input #1 on output #3, press [3][.][1][Enter]. To

blank output #2 so that it doesn’t display anything, press [2][.][0][Enter].

To send input #4’s video to all outputs, press [*][.][4][Enter]. Remember

that any number of outputs can be switched to display the same input, but

no output can be switched to display more than one input at the same time.

After you press each key, you have five seconds to press the next one; if

you wait longer than that, the switching command is aborted. If at any time

you press an invalid key or a key that the Switch isn’t expecting, the

command is also aborted. For example, if you press [4], and then [.], but

then press [5], or [.] again, or any unused key, the command in progress is

discarded and the Switch resets itself.
