Device Application problem with collation

Dear Sirs,
I am writing a device application that connects to SQL 2005 srever (collation is Arabic_CI_AS on the server), it is working just fine, but when I tried the same application on aonther device that has a different collation it does not connect to the server because of the collation, when I change the collation (as a test) for the server and all used columns in the tables to Latin1_General_CI_AS it works.
is there a solution for this problem without changing the collation to all database tables columns?

Are you using unicode data types if not use unicode...
And also check the following article article...

I am using unicode date types (nvarchar), but the collation of the column is <database default> which is Latin, but I do not want to change it.

Try this thread,

But, its always good to have all the servers running with same collation.
