It appears the last two bytes (BF BE & 23 0F) are a checksum of some sort for the serial number...anybody have an idea? 004A C4A2 = #4900002 CS=BEBF? 0048 DC58 = #4775000 CS=0F23? John :-#)# At 07:38 AM 19/09/2002 +0000, steve@coule.freeserve.co.uk wrote:
So what I have is two 32 byte data streams, the first one (old base) is serial number 4900002 (unknown Site Code) is: A2 C4 4A 00 42 03 FF FB 01 00 0A 00 03 50 08 40 00 00 00 00 00 03 00 00 FE 02 00 00 00 00 BF BE
And serial number (NOS) 4775000 "Site Code 1" is: 58 DC 48 00 42 00 FC 00 FC 00 00 00 03 50 08 20 00 00 00 00 00 00 00 00 FE 02 01 00 00 00 23 0F
I suspect the first three bytes are the serial number...maybe...
The first three bytes are the serial number! Just put the hex numbers 004ac42a into calculator as a hex number, convert to decimal and it's 4900002 ... he other works too!
