4 digit addressing

I have quite a few proto 2000 diesels I want to address with their engine numbers. Evidenrly there is a formula around to figure out the variables to be able to do this. Does anyone have a link to the formula. Quantum engineering or sum such. Thanks in advance Bwchaney

what dcc system are you using? some older systems don’t support 4 digit addressing. new systems do it automatically. a quantum engineering degree is not required.
