GENERAL INFORMATION
1-10
The Revision Letter in the radio identification
number (see Section 1.5) can be used to determine if a
VHF radio has this new Version B board. Radios with
a Revision Letter of “B” or later have the new board
and PCTune 1.10.0 or later must be used.
Version C - These boards are a completely new
design. Highlights of this board version are as follows:
•
Because of different interface requirements, the new
Version C logic and UI boards described in the next
section must be used. This logic is PowerPC-based,
similar to Version A and B.
•
A new version of the PCTune software (2.0 or later)
is required to tune radios with these boards.
•
The new 800 MHz version of this board operates on
both 700 and 800 MHz channels instead of only 800
MHz channels like the A and B versions. Therefore,
radios with the Version C board can operate on
channels from 762-870 MHz, while radios with the
earlier Version A and B boards can operate only on
channels from 806-870 MHz.
Radios with this new 700/800 MHz RF board have
a “7” as the “F” character of the radio part number
(see Section 1.4), while radios with the older A and
B versions have an “8” for this character.
1.13.2 LOGIC AND UI BOARD CHANGES
As shown in Figure 1-1 and Table 1-4, there have
been three significant changes to the control logic used
in 51xx series radios. More information on these
changes follows.
NOTE: The firmware version number (1.x/2.x/3.x) is
briefly displayed when radio power is turned on.
Version A - This version of logic and UI boards
provides software generated encryption (Version 1 in
Table 1-4). DES-XL and FIPS 140-2 approval is not
available with these models.
Version B - This version began shipping in mid 2003
to provide FIPS 140-2 approved and DES-XL encryp-
tion. SEM and UCM versions of these boards are
available (Versions 2 and 3 in Table 1-4). These boards
have separate encryption modules to provide encryp-
tion instead of doing it through software. The SEM
and UCM versions are functionally the same except
only the UCM version provides DES-XL encryption.
Normally, the SEM version is used unless DES-XL
encryption is required.
Version C - This version of the logic and UI boards is
a new design that is required to interface with the new
Version C RF module. Only a SEM version will be
offered (similar to Version 2 in Table 1-4). This
version of boards has more Flash and RAM memory
to allow additional features to be added if necessary.
This logic version uses Version 4.x.x firmware.
