For other encryption modules, check with a Tait Service Centre, or www.taitworld.com/.
Modules listed can be fitted to either TOP or T2000 radios, with the exception of the Midian
TVS-2 modules (see above). However, the modules will require some customisation to suit the
radio type. Details are included in the module manufacturer’s documentation, but differences
include:
removal of snap-off sections to fit a module into a TOP radio. Note that these snap-offs
include screw holes necessary to fit the module into a T2000 radio, so should not be
removed for T2000 application.
some modules require module-specific link settings on the Encryption Upgrade Flex PCB,
depending upon the radio type and the system configuration. These settings are described
in the module manufacturer’s documentation.
2.4 Radio Hardware Compatibility
Tait Orca Portable Radios
The TOP Encryption Upgrade Flex PCBs described in this manual are suitable for use in most
TOP 5000 radios (5010, 5020, 5035, 5040). The flexes can be retrofitted to most radio models,
but this should first be verified by providing the serial numbers to a Tait Service Centre for
confirmation.
T2000 Radios
The T2000 Encryption Upgrade Flex PCBs described in this manual are suitable for radios which
contain the Enhanced HC11 Control PCB (IPN 220-01344-XX). This can be verified by
providing the serial numbers to a Tait Service Centre for confirmation.
2.5 Radio Firmware and Software Compatibility
Tait Orca Portable Radios
Encrypted TOP radios require specific encryption-capable radio firmware. This is fitted during
manufacture of encryptable radios, but will need to be programmed separately where an
encyption upgrade kit is used. Contact the Tait Strategic Sales Team for confirmation of
encryption firmware support.
T2000 Radios
Encryption-capable T2000 radios require no firmware change to support encryption function.

Copyright TEL Encrypted Radio Programming and Service Manual
3 System Operation
Encrypted radios provide increased privacy for conversations by jumbling speech so that only
radios with the right hardware and settings can reconstruct it. The diagram below shows a typical
radio system comprising portable radios, mobile radios, base stations or repeaters and an OTAR
(Over-the-Air Reprogramming) programming station.
Whether or not a radio transmission is encrypted is the user’s choice. When the encryption mode
is selected, the radio sends and receives encrypted calls to and from other radios with compatible
encryption module and settings (keys or codes). However, even when encryption is not selected,
an encryption-enabled radio will always decode encrypted communication from any radio with
compatible modules and settings.
When modules or settings are incompatible, communication is reduced to unintelligible noise.
3.1 Configuration
Both encryption modules and radios have many settings which affect encryption. You will need
to refer to the installation and programming manuals provided with all your encryption hardware.
This manual describes how to connect your hardware for setup, testing and maintenance, but
does not describe how to determine the settings you should use. These should be determined
during system design by technical personnel trained in the relevant Tait and third-party products.
Contact your Authorised Tait Service Centre for further assistance.
3.2 Compatibility
Some combinations of encryption hardware, software, radio versions and configurations,
accessories and programmable features may not be supported. In particular:

14 System Operation M2259-00-200-812

Encryption modules from different manufacturers are not compatible
Features available in a Tait Encryption-enabled radio are not necessarily the full list of
features specified by the module manufacturer.
The system designer should confirm that the system meets user requirements.
3.3 Tait Encryption Interface Signal Specifications
For TOP Encryption Interface Signals, see page 15. For T2000 Encryption interface signals, see
page 48.

M2259-00-200-812 Tait Orca Portable (TOP) Encryption 15
Copyright TEL Encrypted Radio Programming and Service Manual
4 Tait Orca Portable (TOP) Encryption
Tait Orca Portable (TOP) radios can be encryption-enabled at a Tait Authorised Service Centre
using the TOP Encryption Upgrade Kit (IPN TOPA-EA-001) and a supported Transcrypt or
Midian Encryption Module. This kit comprises a flex circuit which brings all the required
connections for encryption to a single connector for plug-in encryption functionality. Full fitting
instructions for the flex are included in this manual.
Note: Module component values change between TOP and T2000 radios. Ensure the module
fitted has been configured for the TOP radio. See the encryption manufacturer’s service
manual for more information.
User Interface
This is a hardware and firmware solution. It offers:
user control of Encryption state (On or Off) by any Function button, programmed by the
user, with either short or long press activation
menu access to Encryption state (where menu function is available)
Where the radio has both a display and a keypad, it also provides:
encryption state by text on the radio display
user control of up to 16 encryption codes by keypad
continuous display of the currently selected encryption code
programmable control of the number of user accessible codes
display of the ‘accessory triangle’ indicating when transmitting or receiving encrypted
signals (Transcrypt modules) or if the encryption state is ON (Midian modules).
4.1 Circuit Operation
Functions of the interface are:
Transmit and receive audio is intercepted by the flex, where C572 and C567 are removed.
Audio passes through the encryption module and is encrypted or not according to the
encrypt state.
Links (not shown on the block diagrams, see the circuit diagram on page 21) allow the radio
to function as a standard, unencrypted radio when an encryption flex is fitted with no
module. To enable the radio to operate when a module is not fitted (-06 flex version only),
solder-short Link-6 and Link-7 to loop the audio back to the normal radio path. Radios with
-07 (or later version) flexes fitted do not require these links fitted.
The existing flex circuit that connects the Main PCB to the User Interface PCB is discarded,
and is replaced by the encryption flex circuit.The low voltage reset from the radio is used
to reset the module circuit.

The diagram that follows shows the encryption circuit operation for both a TOP encrypted radio
and a TOP radio as a programming radio.
Note: When using a TOP radio as an OTAR programming radio, ensure encryption mode is
turned off.
An addressable latch on the radio UI board is replicated on the encryption flex and driven by the
same serial data bus. The radio micro uses four outputs of this latch to control the encryption
code select bus. Two other outputs provide the PTT and Mode drives to the module. The
remaining two pins function as normal for the UI board and are unused on the flex.
The external PTT and internal PTT are combined within the radio software to provide the PTT for
the module.
The radio LED is under normal micro control, and provides no indication of encryption status.

The module IND (status) output is fed to the SENSE-1 input to the radio micro. This allows the
software to display the status on the LCD accessory annunciator.
Encryption code control is achieved by keypad entry. Encryption Mode can be assigned to a
function key when the radio is programmed or through a menu. (On most radios, this function is
user-programmable.) This can be a long or short press of any valid function key, usually a long
press of Function-2 key.

a computer with OTAR programming software
a Transcrypt Programmer
a TOP or T2000 Lead (part of the TOPA-EA-002 Encrypted Radio Programming and
Service Kit) for OTAR programming
or
a direct programming cable (TOPA-EA-008G) for direct programming
a TOP or T2000 radio to use as a programming radio (OTAR only)
Transcrypt modules fitted to a TOP radio can be programmed using Over-The-Air-
Reprogramming (OTAR). The OTAR programmer allows a computer to alter a radio's encryption
module settings remotely, within the coverage range of the radio system.

M2259-00-200-812 Tait Orca Portable (TOP) Encryption 19
Copyright TEL Encrypted Radio Programming and Service Manual
For direct programming, the module is programmed directly, using a TOPA-EA-008G cable
connected to the radio’s accessory connector.
Note: Any TOP radio can be used for OTAR programming. However, if an encryption
module is fitted, it is important that the encryption function is turned off when
programming.
Note: If a T2000 radio is used for OTAR programming, a T2000 Encryption Flex must be
fitted to the radio. A module is not required, however, if one is fitted, it is important
that the encryption function is turned off when programming.
Refer to the following publications for detailed programming instructions
Transcrypt OTAR Programmer Manual
Transcrypt Module Manual
Transcrypt Programming section (page 69) of this manual
4.2.1 Midian Module Programming
The Midian VPU-12 module is preprogrammed by the manufacturer and does not normally
require programming. Its programmable functions can be programmed by open-radio direct
programming. It does not support OTAR programming. The Midian TVS2 module supports
OTAR programming of encryption codes only. However, the TVS2 supports direct programming
of all programmable functions.
Refer to the following manuals for detailed programming instructions
Midian Programming instructions
Midian Module Manual
Midian Programming section (page 79) of this manual
Important Additional Information
Once encryption is enabled, set the function buttons to:
turn encryption ON and OFF
access Code Change mode (optional)
set the number of user-accessible codes (optional)
Economy mode is the factory default, but is not recommended with
encryption-enabled radios as it will cause loss of sync pulses. This may result
in failure to decode some encrypted calls after a period of inactivity.
If the flex version is -06 (or earlier), to enable the radio to operate as a
standard, unencrypted radio when a module is not fitted, solder-short links
Link-6 and Link-7on the flex. This modification will loop the audio back to
the normal radio path. See the PCB layout section on page 21 of this manual
to locate the links.
If radios have no display, ensure no other function (eg incoming selcall or
repeater talkaround) is programmed to utilise the orange LED, or it will be too
difficult to determine encryption status.
4.3 Programming the Encryption Module

Encrypted Radio Programming and Service Manual Copyright TEL
Equipment setup and programming instructions are described in the Transcrypt Programming
section on page 69 or the Midian Programming section on page 79, depending upon the origin of
the encryption module. Refer also to programming and service manuals with your Transcrypt or
Midian encryption module and programmer.

4.4 Testing the Encryption Module
Equipment setup and testing instructions are described in the Transcrypt Programming section on
page 69 or the Midian Programming section on page 79, depending upon the origin of the
encryption module.
With encryption off:
Check normal power-up of the radio, with the normal display messages and confirmation
tones.
Check that receive and transmit audio are functioning, using a service instrument or another
radio on the same channel.
With encryption on:
Check that receive and transmit audio are functioning, using another T2000 or TOP radio
with the same encryption module, programmed with the same codes, on the same channel.
Where a code hopping module is fitted, confirm encryption is active by listening for the
initial sync burst on the receiving radio
Where a code inversion module is fitted, confirm encryption is active by pressing any
function key - the confidence tone will be a higher frequency than normal.
Check the Encryption User Interface features – status indicators, encryption settings etc.
