The following diagram shows the principle of addressing two racks at the same address.            
NOTE:              
- 
TSX RKY 12EX racks cannot have a second rack at the same address.            
 
- 
TSX RKY 8EX/6EX/4EX racks can be intermixed.            
 
- 
Two TSX RKY 8EX/6EX/4EX racks at the same address will not necessarily be linked one after the other. The order of physical distribution is not important.
