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

This chapter defines the set of update notifications concerning SI send by the CCU. Each description is 
according to the definition given in section 4.1.1. 

As for the SC application, update notifications for SI are also the results of user actions done on the actual 
units. This section gives a unit/user event matrix for the SI application in which the possible user events are 
linked with the corresponding update notification(s). For some events also the required remote functions to 
continue the System Installation process are given. 
The update notifications themselves are described in the remaining sections of this chapter.

Notifies the remote controller that during global installation (which implies that the CCU is in config mode, see 
SI_C_START_INSTALL section 5.2) a soft key is pressed on a installable unit. A installable unit is a unit 
which can be assigned with a seat number.  
An overview of installable unit types is given in section 5.4. 
The remote controller should use this update to assign a seat number to the unit identifier given with this 
update notification. 

The update comes with the following structure: 

typedef struct 
{ 
 WORD 

wUnitId; 

 BYTE 

byUnitType; 

} SI_T_UNIT_STRUCT; 

The unit identifier of a unit. Also called unit-number. 

The type of the unit. The different unit types possible are given 
in section 3.6.
