RCM Professional is the ultimate software for time-keeping and race management and is based on RCM Ultimate but is limited in some ranges. RCM Professional is the ideal and cheap solution for a club or also an individual not running international championships (European Championship / World Championship).
The concept of RCM Professional is a client-server architecture. To avoid that RCM Professional is overloaded with complex and partly customer specific needs, special functions not related to the time keeping have been realized in client-programs, which connect to RCM Professional. To use those clients, you have to use a network. RCM Publisher (result publishing in the drivers area), RCM Voice (separate Voice announcements) and RCM Signal (signal control) support RCM Professional and can help you with the race organization.
