4. Multiple Connection Mode
4.1 Overview
WCS-232 supports multiple connection up to 1:4. There are two supported modes: Multi-Drop mode and Node
Switching mode.
Figure 4-1 Multi-Drop mode
Multi-Drop mode supports real-time two-way communication between one master and up to four slaves
simultaneously, as shown in figure 4-1(Please refer to 3.8.3 1:4 Connection for connection method).
Figure 4-2 Node Switching mode
Node Switching mode maintains all slave connections but the actual communication is made in 1:1 as shown in
Figure 4-2. Once the connection with slave is complete, it operates in command mode, and slave-master
communication changes will be made using AT Commands.
