    DESCRIPTION

    The TVS-2 series of tactical high-security rollingcode scramblers offers protection against even determinedlisteners. By using true frequency hopping rather thanfrequency sweeping, TVS-2 offers higher security thancompetitive rolling code scramblers. While competitive rollingcode scramblers claim up to 1,000 hops per second, each ofthese hops are only a cycle or two in length. Midian's TVS-2hops 6 to 12 times per second in standard mode and 13 to 25times per second in advanced mode. Each hop is severalhundred cycles in length.

    The TVS-2 Series CAD-300 Computer-AidedDispatch also offer features such as Over-The-Air-Reprogramming (OTAR) of the primary security code, DeadbeatDisable, selective calling, spy, ANI, and Emergency ANI usingKryptic signaling format.

    APPLICATIONS

    Midian's scramblers are ideal for government (i.e. military),public safety, fleet and private use.

    INSTALLATION

    The TVS-2 VX is a plug-in module for Vertex's VX-600/800/900 portable radios. The TVS-2 does not require anymodifications to the repeater and have no effect on the rangeof the radio. Our voice scramblers are well known in theindustry as offering the best audio quality and speakerrecognition.
