    Default Becker 6 Preset Algorithm (5 digit code)

    I am interested in the mathematics of the algorithms behind the various radio code calculators (from SERIAL NUMBER ) and am currently looking at the readily available Becker Code calculators

    Does anyone on here know (and is willing to explain fully ) the details behind the common BECKER 6 Preset Algorithm (5 digit code)


    If this information is not to be discussed on the open forum then please send me a PM

    I am willing to offer a few beer tokens to anyone who can provide any explanation that allows me to understand more fully the method used.

    Thanks

    Thanks for the replies

    My question is NOT a code request.(I already have a Becker calculator )

    It is also NOT an EEPROM Dump reading request either.(I know how to do that)

    I want to discover the mathematical method used in the actual algorithm used for calculating these Becker Preset 6 ( 5 digit codes codes ) using the SERIAL NUMBER

    Okay, I also am interested but you have to upload the dump with the code to tell where is the encryption

    Sorry...this is not an electronics question about EEPROM dump reading an existing code for one particular radio..

    I am trying to discover the fundamental mathematics used to create an algorithm that decodes the original code for the radio using digits taken from that radio`s unique Serial Number.

    There are already a collection of these Becker Calculators available that have working algorithms to calculate the working code from the Serial Number and I want to discover the mathematics used in these programs producing the working code.

    Unfortunately , I do not have the knowledge to "reverse engineer" any of these working calculators` software in order to discover the maths being used....so that is why I`ve asked the question on this forum as I understand there are people on here that may have this knowledge

    in the 4 digit code the codes go up in batches of 64 (each number increases code by 8 ie 0001 = 0008 and 0002 = 0016)in the following sequence



    0001 to 0063 = number *8 ........ serial 0063 = 0504 ..... then 0064 jumps to 4096

    0064 to 0127 = 4096 + (number - 64) *8 ........ 0127 = 4600 ..... then 0128 jumps to 8192

    0128 to 0191 = 8192 + (number - 128) *8 ....... 0191 = 8696
    ..
    0192 to 0255 = 2288 + (number - 2288) *8 ....... 0255 = 2792

    0256 to 0319 = 6384 + (number - 6384) *8 ....... 0319 = 6888 EDIT : 0256 should read 6385

    0320 to 0383 = 480 + (number - 480) *8 ....... 0383 = 0984 EDIT : 0320 should read 0482

    carrying on this sequence should give all codes

    0320 to 0383 = 480 + (number - 480) *8 ....... 0383 = 0984

    carrying on this sequence should give all codes



    Unfortunately , I don`t think the above explanation is correct as


    1... The fundamental basis of this explanation is a number multiplied by 8......but some of the actual correct codes for Becker 4 digits are not divisible by 8


    2...There are also some typo errors .

    For example


    0064 to 0127 = 4096 + (number - 64) *8 ........ 0127 = 4600

    The correct code for 0127 = 4610 which is not divisible by 8

    --------------------------------------------------------
    Also typos plus wrong codes

    0192 to 0255 = 2288 + (number - 2288) *8 ....... 0255 = 2792

    should be

    0192 to 0255 = 2288 + (number -0192) *8 ....... 0255 = 2792
    .....correct code for 0255 = 2793 (not divisible by 8 )

    --------------------------------------------------

    0256 to 0319 = 6384 + (number - 6384) *8 ....... 0319 = 6888

    should be

    0256 to 0319 = 6384 + (number - 0256) *8 ....... 0319 = 6888......correct code for 0319 = 6989 ( not divisible by 8 )

    -------------------------------------------------------
    0320 to 0383 = 480 + (number - 480) *8 ....... 0383 = 0984


    should be

    0320 to 0383 = 480 + (number - 0320) *8 ....... 0383 = 0984 ......correct code for 0383 = 0986 (not divisible by 8 )

    ---------------------------------------------------------

    It does appear that the "multiply by 8" could be a major basis used in a working calculator for these Becker 4 digit codes, but there must be additional factors to be taken into consideration when calculating

    Possibly something like adding an extra "tens" digit if the number goes into double figures.


    Anyone have any further ideas or suggestions...either on this 4 digit calculator or other calculators including the Becker 6 digit?

    Do what I did. Get a Becker calculator and remote control it sending in key presses and then extracting each code for each serial number. Why make it difficult. You then have a table of all codes for all serial numbers. :-)
