Beginning in November 2003, a revised logic 

board began shipping in 5300 models. This board 
utilizes a new control logic design similar to that used 
in the 5100 portable. This board is available in the 
following configurations. All versions are FIPS 
approved.

SEM Version - This version has the EFJohnson 
SEM (Security Encryption Module) soldered to the 
board. It is used whenever DES, DES-OFB, or 
AES encryption is required. It does not provide 
DES-XL encryption.

UCM Version - This includes a plug-in Motorola 
UCM encryption module. It is used whenever 
DES-XL Motorola proprietary encryption is 
required. It also provides DES, DES-OFB, or AES 
encryption. 

No Encryption Version - If encryption is not 
required, either the earlier logic board (see 
following) or the UCM version without the UCM 
module is used. 

This version is Part No. 035-1800-4xx and is 

being replaced by the above versions. This board has a 
jack for plugging in Motorola encryption modules that 
provide DES/DES-XL/DES-OFB and AES 
encryption. It does not use the SEM module. 

PCConfigure programming software, Version 

1.21.2.5 or later is required to program radios with the 
revised board. This software can also be used to 
program radios with the unrevised board. The “5300” 
Radio Series is selected for both boards. The software 
automatically detects which board is used when 
parameters are written to the radio.

Radios with the revised and unrevised logic 

boards use different firmware (operating/Flash soft-
ware) as follows. When downloading code using the 
PCConfigure software (such as when purchasing new 
operating features), the radio must be powered up 
when the password is entered so that the logic board 
version can be detected.

Models with Revised Board - A single code file is 
used similar to the 5100 portable. SEM code has a 
2.xx version number, and UCM code has a 3.xx 
version number. 

Models with Unrevised Board - Two code files 
are used, one of which programs DSP parameters 
and the other which programs ARM processor 
parameters. These code sets have a 1.xx version 
number.

Refer to the radio Serial Number on the label on 

the bottom cover to determine if it is a version with the 
revised logic board. Radios with the new revised logic 
board have a Revision Letter (letter following 53xx0) 
of “G” or higher. Radios with an A-F Revision Letter 
have the early unrevised -4xx logic board just 
described. 

The board version can also be determined by 

noting the software version number that is briefly 
displayed when power is turned on. The version 
numbers are as follows:

Ver 1.xx

Early unrevised

Ver 2.xx

SEM version

Ver 3.xx

UCM version
