Highlight changing numbers in column

Dear Experts:

I got a row of alphanumerical strings in Column A. Whenever the alphanumerical string changes to another the first occurrence is to be highlighted in some way. The best would be: cell fill red and cell font white.

Help is much appreciated. Thank you very much in advance. Regards, Andreas

I have attached a sample  file for your convenience.

Example:

O/243
O/243
O/243
S/374

G/192
G/192
K/334
L/419
S/342
F/224
F/224
T/343
T/343
etc.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can use conditional formatting with below formula
=COUNTIF(A$1:A1,A1)=1
