The 3U MACRO Station can be configured in either of two fundamental assemblies – “UMAC MACRO” and 
“MACRO Stack”: 

 

• 

• 

UMAC MACRO – In this configuration (once called 
"Pack") the 3U-format boards are put together to 
communicate through a backplane bus called the UBUS.   
All boards are installed in a Euro-card rack.  In this 
configuration, all 3U-format boards or modules can be 
installed or withdrawn from the pack individually, 
providing ease of installation, debugging, and repair.   

The photo at the upper right shows a UMAC rack with power 
supply and I/O boards that are connected through a backplane.  
This system allows for an easier integration of the 3U 
MACRO-CPU for larger (up to 8 axes) applications. 

MACRO Stack – In the Stack configuration the 3U-format 
boards are put together as a stack of piggyback boards, 
(right, below).  This configuration is ideal for compact, 
cost-sensitive embedded applications.   

 

 

The Stack boards and related breakout boards can be installed in a Euro-card rack, 
creating a hybrid “stack/pack” configuration.  This requires a special backplane 
configuration that makes removing stack boards difficult.   

This hybrid configuration is now recommended for existing “legacy” systems only.
