GENERAL INFORMATION VS-1200: The VS-1200 is a Digital Signal Processor (DSP) based Frequency Domain voice scrambler offering a high level of voice privacy. The DSP converts the analog signal into quantitized digital data. It then converts the “Time Domain” signal into the “Frequency Domain”. This results in an audio “frequency spectrum”, which is then partitioned into bins that are encrypted by the non-linear key generator. The digitized data is converted back to the analog realm using a digital to analog converter. The above technique and the lack of synchronization result in excellent audio quality, high security and enable the VS-1200 to be used in virtually any type of radio system. These systems include HF SSB, Conventional Two-Way, Trunking, Voting and Simulcast. In addition to the scrambling functions the VS-1200 offers ANI and Emergency ANI encode in the following formats: Motorola’s MDC-1200 Kenwood’s FleetSync Harris’ G-Star (aka GE-Star) DTMF 5-Tone (all formats) VS-110: Midian’s VS-110 is a rolling double inversion scrambler that offers 1020 possible codes (4 groups with 255 codes per group). Of these codes the scrambler may be programmed with up to 4 of these codes. The VS-110 series is compatible with Icom’s UT-110. VS-1100: Midian’s VS-1100 is a double inversion scrambler (aka split-band scrambler) that offers 32 possible codes. Of these 32 codes the scrambler may be programmed with up to 4 of these codes. The VS-1100 series is compatible with Midian’s VPU-6, Icom’s UT-109 or Inysa’s XPTO. VS-1000: Midian’s VS-1000 voice inversion scrambler provides an entry level of voice security for two-way radio communications. The VS-1000 provides up to 4 different inversion frequencies that are button selectable. These inversion frequencies are programmable. The VS-1000 is compatible with Midian’s VPU series voice inversion scramblers. VS-1050: Midian’s VS-1050 is a voice inversion scrambler with multi-format ANI encode. The VS-1050 has the same scrambling features as the VS-1000, but adds ANI and Emergency ANI encode in the following formats: Motorola’s MDC-1200 Kenwood’s FleetSync Harris’ G-Star (aka GE-Star) DTMF 5-Tone (all formats)

RADIO PROGRAMMING NX-200/300: Note: The radio firmware must be at least 2.00.00.01 and the radio programming software must be KPG-111D version 2.00 or higher. 1. Under the “Edit” menu select “Extended Function” and set “Optional Board” as “Voice Scrambler”. OPT11

should be set as COR or TOR and Echo PTT should be checked. The Echo PTT should only be unchecked if using Emergency ANI. To program the unit through the radio the Optional Board Programming must also be checked.

2. If scrambling on a per channel basis is desired or a combination of a mode button and per channel, then from

the “Zone Information” screen click on the “Channel Edit” button. Under “Scrambler Setting” enable the “Voice Scrambler”. For scrambling on a per channel basis, this will need to be done for each channel where scrambling is desired. If the box is checked, the radio will power up in coded mode & when that channel is selected. When per channel scrambling is used, it is still possible to toggle in and out of scramble mode.

If the scrambler will be used with multiple codes, then select which code (1-4) that is desired for that channel under “Scrambler Setting” “Scrambler Code”. 3. When using a button to turn the scrambler on and off program the desired button to “Scrambler/Encryption”.

4. If using Emergency ANI, under Edit > Key Assignment set the AUX button to None.

PRODUCT PROGRAMMING Note: Greater details of the VS series products can be found in the VS Series Technical Reference Manual. Midian’s VS-1xxx-KW3 is programmed through the radio using the radio’s programming cable (KPG-36 or KPG-46) and Midian’s MPS programming software. From the product selection screen in the MPS software, select the desired product from the list and click OK. Note: The radio firmware must be at least 2.00.00.01 and the radio programming software must be KPG-111D version 2.00 or higher. Set the parameters of the scrambler software to fit the application. If any clarifications on a feature are required, move the mouse cursor over the feature name until the question mark appears and right click, a definition of the feature will be shown. Note: On the General settings tab the “Program Through Radio Enable” box must be checked. After entering the parameters, save the file by going to File - Save As. Enter the file name in the File Name block and click Save. Saving the file will allow for quick and easy reprogramming of units. Important Note: Upon entering through the radio programming mode, the scrambler needs to be read or programmed within 15 seconds or the scrambler will go into sleep mode. With the radio programming cable connected (KPG-36 or KPG-46) to the radio, press and hold the > button (Right/Home button) while turning power on to the radio. The radio’s LCD will display “OPT Board Prog”. Select ProgramUnit or ReadUnit in the MPS software. Note: The VS-1200’s security pass phrases can use any 8-bit ASCII keyboard characters. These include the characters on a typical English keyboard such as 0-9, A-Z (upper and lower case), *, #, @, $, etc. Spaces are also allowed. Midian does not recommend using international language character such as ñ, ä, ß, ü, é, etc. as these have not been tested. Please also note that the pass phrases are case sensitive. Important Note: Do not attempt to ‘clone’ the scrambler by reading one and then programming another. When the scrambler is read, the pass phrases will be read out as “<undefined>”. If another scrambler is then cloned with this information, the scramblers will be incompatible because they have different pass phrases. To ensure scramblers communicate with each other, program them from a saved file.

HARDWARE ALIGNMENT

This section describes how to determine and set the audio levels. Audio Levels Overview: To ensure the best audio quality, the scrambler must be configured to match the audio levels used by the radio. The scrambler uses programmable gain amplifiers to accomplish this. Determining the gain settings for these amplifiers is an involved process, so Midian simplified this process by developing an algorithm that requires the technician to make only four voltage measurements. From these four measurements, all of the many internal settings are determined. Still, getting the best audio quality will likely require a bit of trial and error. The scrambler only has control of audio voltage levels, not input and output impedances. These impedances can dramatically influence the levels. The Four Voltage Measurements: An oscilloscope and a communications test set/service monitor are required for the measurements. It is recommended that the measurements be recorded in units of mV peak-to-peak. Each measurement must be taken with system modulation at either 60% or 100%, but Midian recommends using 60% These measurements must be taken within 15 seconds of powering the scrambler on. This is because the scrambler may enter power saving mode after that time. Measurements made while the scrambler is in power saving mode will not be valid. The unit ships with the power save feature enabled by default. The power save feature can be disabled via the MPS programming software so that it will not interfere with taking measurements, if desired. Please note that the levels provided to the option board may be different between narrow band and wide band. TX Alignment Set-Up: A method for controlling transmit modulation is required for accurate measurements in the TX mode. A small speaker held in place near the microphone by a rubber band can serve this purpose in most cases. Use a sine-wave generator to inject a 1000 Hz tone into the speaker. Adjust the output of the sine wave generator so that the transmitter produces 60% of rated modulation while PTT is pressed. Note that if the audio source (such as a speaker) is moved even slightly, the TX modulation may change significantly. Care must be taken to avoid changing the TX modulation while taking the measurements. RX Alignment Set-Up: Using a service monitor send a fully quieting signal (-50 dBm) to the receiver with a 1000 Hz tone at 60% modulation, adjust the volume of the receiver to a comfortable listening level and measure the audio level at the speaker using an AC coupled oscilloscope. Once the volume is adjusted and the measurement taken do not adjust the volume control during the remainder of the alignment. 1. TX Input: The goal of this procedure is to determine the audio level that the scrambler board will see at the

TX audio pickup point after it is installed. The scrambler must be installed and powered-on while making this measurement. Use the TX Alignment Set-Up procedure and measure the audio level at TP1 on the scrambler.

2. RX Input: The goal of this procedure is to determine the audio level that the scrambler board will see at the

RX audio pickup point after it is installed. The scrambler must be installed and powered-on while making this measurement. Use the TX Alignment Set-Up procedure and measure the audio level at TP2 on the scrambler.

3. In the VS-1xxx programming software under audio levels set the TX In to the same level as measured in step

1 and for a preliminary adjustment set the TX Out for the same level. Set the RX In to the same level as measured in step 2 and for a preliminary adjustment set the RX Out for the same level. Program the VS-1xxx.

4. RX Output: The goal of this procedure is to determine the audio level that would normally appear at the RX

audio insertion point in an unmodified radio. Using the same RX Alignment Set-Up procedure verify the audio level at the speaker is still at the same level measured initially in the RX Alignment Set-Up procedure. If not adjust the RX Out level accordingly.

13

5. TX Output: The goal of this procedure is to determine the audio level that would normally appear at the TX audio insertion point in an unmodified radio. Using the same TX Alignment Set-Up procedure verify the modulation is still at 60%, if not adjust the TX Out level accordingly.

Programming the Audio Levels: After determining the audio levels at the audio hookup points, it will be necessary to program the scrambler to match these levels. In the programming software, there is a slider control on the Audio Levels Screen for each of the four audio hookup points. Locate the column that corresponds to the modulation and units of measurement for each of the audio hookup points. Adjust the slider bar such that the value appearing in the appropriate column matches what was measured as closely as possible. The following table shows Midian’s recommended levels for the VS-1200 and VS-1100 at 60% modulation (mVpp) for tested models of radios:

Radio Model RX In TX In RX Out TX Out NX-200, NX-300 642 222 648 222 NX-700, NX-800 800 126 678 126 The following table shows Midian’s recommended levels for the VS-1000 and VS-1050 at 60% modulation (mVpp) for tested models of radios:

Radio Model RX In TX In RX Out TX Out NX-200, NX-300 648 222 630 246 NX-700, NX-800 660 114 660 114

OPERATION

Mode Selection: Mode selection means a method of turning the scrambler on and off. In the VS-KW3 series there are two ways of doing this: Per-Channel Scramble On/Off: If scrambling on a per channel basis is being used, then switching between a scrambled or non-scrambled channel will cause the symbol to appear or disappear. Scramble On/Off Button: Press the radio key that was assigned in the radio programming. A tone will be emitted from the radio and the symbol will appear on the display of the radio indicating scramble mode. Code Selection: The VS-1200-KW3 can have up to 3 different codes programmed and the other VS-KW3 series scramblers support up to 4 codes. The codes can be selected on a per-channel basis. Different codes can be accessed by setting the desired scrambler code (1-4) for a radio channel using the “Scrambler Setting” under the “Zone Information” screen’s “Channel Edit” button. Switching to the various channels can supply the user with the desired code. The scrambler should be programmed with the same number of security codes as are programmed into the radio. The scrambler should be programmed as “Binary Select Enable” under the “Security Settings” or “Inversion Codes” tab. ANI Encode: When the PTT button is pressed, the unit will assert the PTT Output and send the programmed ANI tones out the TX Tone Output. ENI Encode: When the Emergency button is pressed, the unit will assert the PTT Output and send the programmed Emergency ANI tones out the TX Tone Output. Note: On the portable radios the emergency from the external mic is not supported.

TECHNICAL NOTES

Radio Compatibility: Midian has taken the utmost care to ensure the option board integrates into the radio with minimal impact to the features of the radio. However, some features may not be available in the radio when an option board is used. If a feature is not available, please contact Midian to see if the feature can be added. Beeps: Go-Ahead beeps, emergency warning beeps and locator beeps are not supported in these radios.
