ISM4 INSTALLATION & PROGRAMMING MANUAL

system upon detection of a change of state on any 

Source Sense Input

.  This feature can be enabled/disabled 

via the 

Enable/Disable Automatic Source Power Notification Commands

 explained in the 

ISM4 RS232 

Command Strings Table

 above. 

 
The 

Source Power Notification Data String

 contains 

Power Status

 information for all four 

Sources

.  The 

Notification Data Structure

 is 

preceded

 by the ‘

#

’ character prefix and 

terminated

 with the ‘

+

’ character. The 

Notification Data String

 is parsed into four fields.  Each field holds one 

Source Component State Data 

Structure

 (one per Source Component).  Each 

Source Component Data Structure

 holds information that 

identifies the particular 

source

 component and its 

power state

, as indicated by the definition of {0/1}, a ‘

0

’ 

indicates the 

OFF

 condition.  A 

‘1’

 indicates an 

ON

 condition. 

 
Example 
 
 
  #SS{S#} PR{0/1}      SS{S#} PR{0/1}      SS{S#} PR{0/1}      SS{S#} PR{0/1}+ 
 
The 

SS{S#} 

field indicates which 

Source

 is being reported.  All data that follows will pertain to 

that

Source

.  The 

end of the current field will be flagged by the presence of another 

SS{S#}

 field (next Source) or the 

‘+’

 termination 

character (end of report). 
 
The 

PR{0/1}

 field indicates the 

Power State

 of the reported 

Source

.  That is, it indicates the 

Power State

 of the 

Source

 identified by the 

SS{S#}

 field that immediately precedes it. 

 
The string below is an example of a string that might be sent out by the ISM4: 
 
#SS1 PR1 SS2 PR1 SS3 PR0 SS4 PR0+ 
This string indicates the following: 
Source 1 Power State = ON 
Source 2 Power State = ON 
Source 3 Power State = OFF 
Source 4 Power State = OFF 
 
The 

System Info Query

 can be useful in determining the build of a particular ISM4. On occasion, Xantech 

Technical Personnel may ask for this information should a problematic situation occur.
