Bosch Security Systems B.V. | 2003 December | SC & SI Remote Interface Description 

The function returns the following structure: 

WORD 

 wNrOfInstances 

The value of the update use count for the SC application at the 
end of the function handling. It contains the number of times a 
remote PC has been connected over the same communication 
medium. E.g. the first time the function SC_C_START_DCN is 
called, it contains the value 1. 

SC_E_NOERROR 

SC_C_STOP_DCN 

Indicates the CCU that the remote controller no longer requires updates from the SC application inside the 
CCU. After receiving this function the CCU decrements the update ‘use’ count. As long as the update use 
count is greater than zero, the CCU remains sending the update notifications to the remote controller. 

Note that: 

Upon communication lost this function will be activated, if SC_C_START_DCN was 
activated. The activation of this function is repeated till the update use count 
becomes zero. 

This function is available in CCU system modes config and congress. 

The function has no additional parameters.
