TM8000 Encryption
Note
At the time of printing, this section applied to TM8100 and
TM8200 series radios, with approved Midian encryption modules
fitted.
The TA2434-01 TM8000 encryption options board allows compatible
Midian encryption modules to operate in the TM8000. Mounted in the
options area of the TM8000, the board uses the same encryption modules
as the TOP radios. No link or programming changes are required to the
modules, so suppliers require only one version of each module.
The Encryption Options board provides all the required connections for
encryption to a single connector for plug-in encryption functionality. It
provides the following connections:
■
to the TM8000 radio main board SK102 options connector via an 18-
way micro-match loom
■
for module programming, external control etc, 15way high-density D
range external connector
■
to the encryption module mounted on the options board, a 20-way
connector via the flexible loom (IPN 219-02129-00 - supplied)
All encryption-enabled TM8000 series radios are factory-fitted with a
special version of radio firmware. However, programming software is
model-dependent as follows:
■
in TM8100 radios, standard programming software is required, with
encryption-specific I/O settings as default. These are documented
under “Programming the TM8000 radio” on page 52 of this manual.
■
in TM8200 radios, a custom version of the programming software is
required, with encryption-specific I/O settings as default. These are
documented under “Programming the TM8000 radio” on page 52 of
this manual.

User Interface
This is a hardware and firmware solution. It offers:
■
user control of Encryption state (ON or OFF) by any Function button
(default F1), programmed by the user, with either short or long press
activation
■
encryption state indicated by steady LED above F1
■
in code change mode, user control of up to 16 encryption codes using
the channel change buttons
■
control of the number of user-accessible codes
