How it works
1. Multi-Drop ModeOne master and up to 4 slaves can communicate with one another simultaneously in both direction.  2. Node Switching Mode Up to 4 slaves remain connected to the master, but only one slave communicates with the master at a time. The master selects a slave to communicate with using AT commands. Application Example: One Parani-SD1000 acts as a master to connect to two slaves. One slave Parani-SD1000 is connected to a barcode reader and the other is connected to a serial printer by serial. Step 1 : First, Master SD1000 receives data from the barcode reader. Then the data is transferred to the application software running on the PC.  Step 2 : Once the the barcode reader data transfer is complete, the application software on the PC sends the AT command to the master SD1000 to change the slave to the one connected to the serial printer, and sends the data to be printed on the serial printer.
