This page only applies to the VS-1200 product.
Number of Keys:
The VS-1200 can have up to 3 codes programmed into the unit. The codes can be
programmed for either Frequency Domain or Voice inversion scrambling.
Power Up In Scramble Mode:
If selected the unit will start up in secure mode when the power is turned on. If it is
desired to have the unit always in secure mode, then check this box and do not assign a button for mode select.
Binary Select Enable:
Not used in the VS-1200-SM1G.
Binary Select Polarity:
Not used in the VS-1200-SM1G.
Equalization:
Selecting Bass will yield louder recovered audio with good low frequency response. Selecting Treble
increases the high frequency response resulting in recovered audio that sounds more crisp but is not as loud. This
setting is a matter of preference.
Note:
All scramblers in the system must have this field set the same.
High Security:
When High Security is selected the VS-1200 is using the Frequency Domain type of scrambling.
Security Level:
The VS-1200 has four levels of Frequency Domain scrambling; levels 0, 1, 2 and 3. Level 0
offers 8 shuffling bins, Level 1 offers 16 shuffling bins, Level 2 offers shuffling 32 bins and Level 3 offers 64
shuffling bins. As the level of security is increased the audio quality will decrease.
Inversion:
The VS-1200’s codes can also be programmed for basic voice inversion scrambling. If selected a
slider bar will appear. Merely scroll with the left/right arrows or grab the slider with the mouse and move to the
desired inversion frequency between 2100 to 4096 Hz.
