GENERAL INFORMATION

The MOT-TVS-2-PRO series is a high-level hopping code scrambler that plugs into the Motorola Professional
series radios. Midian’s TVS-2 uses the 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 Midian’s CAD-300 and DDU-300.

The MOT-VPU-15-PRO series is an entry level voice inversion scrambler that plugs into the Motorola
Professional series radios. The scrambler is capable of features such as ANI, ENI, OTAR, Deadbeat Disable,

RADIO PROGRAMMING

MOT-TVS-2-PRO-M & MOT-VPU-15-PRO-M for Motorola MDC-1200 capable mobile radios
CDM-750, CDM-1250, GM-140, GM-160, GM-328, GM-338, GM-398, PRO-3100, PRO-5100, PRO-7100
Programming Instructions

It is necessary to program the radio before installing the scrambler. This is because the Option Board Feature
of the radio must be enabled in order to program the scrambler using a RIB box and to hear confirmation beeps
from the radio after programming the scrambler.

1. In the Radio Configuration Window under the Option Board Tab, select Advanced Option Interface as the
Option Board Type. Do not check the Option Board Configuration Download box.

2. When programming the “Conventional Personality”, Pre-Emphasis may be enabled, but De-Emphasis must
be disabled. This is because De-Emphasis will prevent the scrambler from decoding synchronization data.
Compression should not be used with the scrambler. No, or Low Level expansion may be used. Check the
Option Board Feature box for all channels if using a button to control the mode of the scrambler. If doing
scrambling on a per channel basis, then check Option Board Feature only for scrambled channels. It will be
necessary to set the power up state of the scrambler to Scramble for per channel scrambling.

The following two steps apply to the accessory connector and may be skipped by most users.

3. An accessory pin may be used to control the transmit mode of the scrambler between scramble and clear.
This is useful in remote control applications. To enable this feature, one of the radio accessory pins must be
assigned to Option Board 1 (Input) via the CPS programmer.

4. An accessory pin may be used to initiate an emergency ANI. This allows for an external emergency foot
switch or button, and frees-up one of the radio front buttons. To enable this feature, one of the radio
accessory pins must be assigned to Option Board 2 (Input) via the CPS programmer. The switch must be
held in the active state for about 2 seconds before an emergency ANI will be sent.

Note: Accessory pin features do not require any special scrambler programming.

GM-339, GM-340, GM-360, GM-380, GM-399, PRO-7200 Programming Instructions

It is necessary to program the radio before installing the scrambler. This is because the Option Board Feature
of the radio must be enabled in order to program the scrambler using a RIB box and to hear confirmation beeps
from the radio after programming the scrambler.

1. In the Per Radio Miscellaneous Window under the Global Tab, select “Advanced” as the “Option Board Type”

and set the RX Audio (Accessory Connector) to “Filtered Squelched”. Note: The Accessory Connector is the
rear accessory connector, but this setting also affects the audio going to the options connector.

2. For each personality, under the Miscellaneous tab, the “Option Board” must be enabled. Check the Option

Board box for all channels if using a button to control the mode of the scrambler. If doing scrambling on a per
channel basis, then check Option Board Feature only for scrambled channels. It will be necessary to set the
power up state of the scrambler to Scramble for per channel scrambling.

3. For each personality, under the “Audio” tab, the “Voice Pre-emphasis/De-emphasis” must be disabled.

CDM-1550-LS+, GM-338-LS Programming Instructions

It is necessary to program the radio before installing the scrambler. This is because the Option Board Feature
of the radio must be enabled in order to program the scrambler using a RIB box and to hear confirmation beeps
from the radio after programming the scrambler.

Conventional Programming:

1. In the Radio Configuration Window under the Option Board Tab, select Advanced Option Interface as the

Option Board Type. Do not check the Option Board Configuration Download box.

2. When programming the “Conventional Personality”, Pre-Emphasis may be enabled, but De-Emphasis must

be disabled. This is because De-Emphasis will prevent the scrambler from decoding synchronization data.
Compression should not be used with the scrambler. No, or Low Level expansion may be used. Check the
Option Board Feature box for all channels if using a button to control the mode of the scrambler. If doing
scrambling on a per channel basis, then check Option Board Feature only for scrambled channels. It will be
necessary to set the power up state of the scrambler to Scramble for per channel scrambling.

LTR Programming:

1. In the LS Trunking Personality window, check the Option Board Feature box for each personality. Check the
Option Board Feature box for all channels if using a button to control the mode of the scrambler. If doing
scrambling on a per channel basis, then check Option Board Feature only for scrambled channels. It will be
necessary to set the power up state of the scrambler to Scramble for per channel scrambling.

2. In the LS Trunking Site window Pre-Emphasis should be enabled, but De-Emphasis must not be enabled.
This is because De-Emphasis will prevent the scrambler from decoding synchronization data. The scrambler
by its very nature performs De-Emphasis function. Compression should not be used with the scrambler.
Expansion should also be disabled.
