GENERAL INFORMATION

TVS-2 Series:

The TVS-2 series is a high-level hopping code scrambler. The TVS-2 uses hopping type rolling code encryption
for higher security rather than sweeping code type and offers 4 user-programmable hop rates and is down
gradable to voice inversion. The scrambler is capable of features such as ANI, ENI, OTAR, Deadbeat Disable,
Spy, and more when using Midian’s Kryptic Signaling format with the CAD-300/DDU-300/TRC-300. For more
information on the TVS-2 please read the TVS-2 Technical Reference Manual.

Note: The TVS-2-VX by Midian is the same module as the FVP-35 sold by Vertex Standard (Yaesu).

VPU-15 Series:

The VPU-15 series is an entry level voice inversion scrambler with Midian’s Kryptic Signaling. The scrambler is
capable of features such as ANI, ENI, OTAR, Deadbeat Disable, Spy, and more when using Midian’s Kryptic
Signaling format with the CAD-300/DDU-300/TRC-300.

PRODUCT PROGRAMMING

Midian’s TVS-2-VX and VPU-15-VX are programmed via Midian’s KL-4 programming interface and the MPS
software.
Go to our website midians.com and under downloads> software download the latest MPS software version. If
using the supplied CD-ROM insert it into the PC’s CD-ROM drive. In the browser that will pop-up, install the MPS
programming software. Be certain that the “Install KL-4 USB Driver” box is checked during the installation
process.

Open Windows’ Control Panel and go to Device Manager.

Open Ports (COM& LPT) to identify the port assignment issued by computer. Plug in the KL4 programmer to the
USB port and the screen will flash and show the device location.

Open the software and choose product from product tree then set appropriate comport selection in the MPS
software as needed.

After the latest MPS has been installed default programming files for specific radio models can be found at:
C:\Apps\Midian\MPS\MPS_vX_xx\Additional Default Files\ TVS2_VPU15\Vertex

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.

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.

Programming: Plug the board onto the KL-4 and connect the green clip lead to the Prog In* hole. Push and hold
the power button on the KL-4 and click “Program Unit” in the MPS software. The ACK LED on the KL-4 will flash
if programmed successfully.

Reading: Plug the board onto the KL-4, connect the green clip lead to the Prog In* hole, and connect the yellow
clip lead to the Prog Out* hole. Push and hold the power button on the KL-4 and click “Read Unit” in the MPS
software.

NOTE: When the scrambler is read, the security codes will be read out as zeroes. If another scrambler is then
cloned with this information, the scramblers will be incompatible because they have different security codes.

*Please reference the pictorial at the end this manual for location of programming connections.*
