MSRGs,b8,b7,
b6,b5,b4,b3,
b2,b1
Create Room Grouping, where:
• ‘s’ is the source which to associate the rooms, (1-8)
• ‘b8’.... ‘b1’ is a binary room selection bitmap where all rooms to
be grouped have a binary 1 in the room position. The most
significant bit in ‘b8’ is for room 64 and the least significant bit in
‘b1’ is for room 1.
Notes:
A room grouping will be considered invalid if there are not at least
two rooms selected for the group.
Only one room group can be associated with any given source.
Example:
MSRG,1,0,0,0,0,0,0,0,37
Groups zones 1, 3, and 6 to source 1.
Note: The number 37 is calculated by applying a binary mask on
the bits to be grouped.
• Zone 1 represents the Least Significant Bit and zone 8, the MSB.
• The binary bitmask for 1,3, and 6 is 0010 0101 which is 37 in
decimal.
