VS-1200-HS1™
H-250 Handset with Frequency Domain Tactical Level Voice Scrambler for Military Manpack Radios

Tactical Voice Scrambler H-250 Handset for Manpack Radios

Description

Midian's VS-1200 series is a Digital Signal Processor (DSP) based Frequency Domain voice scrambler offering multiple tactical levels of voice security. Unlike rolling code voice scramblers the VS-1200 does not require synchronization. The lack of synchronization enables the VS-1200 to be used in virtually any type of AM/FM SSB military manpack radio.

The built in ANI enables the dispatcher or system administrator to monitor fleet communications and to identify and stop system abusers. When the user keys their radio the VS-1200 transmits an ID. This ID can then be displayed on Midian's CAD, DDU, ADD and TRC series display decoders.

When used with the CAD-800 additional features are available including:

  • Over the air data encrypted with a unique System ID using Midian's 1200 baud Fleet Management Protocol, FMP-1200™
  • Unit mutes speaker during incoming Midian FMP-1200™ data packets
  • Leading and/or trailing PTT ANI and Emergency ANI (ENI) displays on the CAD-800
  • Selective call for Individual, Group and All Call
  • Querying a unit to transpond back to the CAD-800 when called to see if the radio is working or in range
  • Spy mode where the CAD-800 can eavesdrop on a lost or stolen unit
  • Disable and re-enable (Stun) a lost or stolen unit from the CAD-800
