Parani-SD1100 supports multiple connections up to 4 slave units. There are two types of multiple 
connection modes: Multi-Drop Mode and Node Switching Mode. 
 

 

 

In Multi-Drop Mode a master unit can connect to maximum 4 slave units at the same time and they 
transfer data bi-directionally as in Figure 4-1. 
 

 

 

 
In Node Switching Mode, the master unit maintains multiple connections with maximum 4 slave units 
but only one connection with one slave unit is active and data is transferred as shown in Figure 4-2. 
Active slave is selected by AT commands.
