Using the default communication parameters
When you forget the baud rate, parity bit, ID, etc. You can short circuit the INIT and DGND, and then power on. The module will use the initial values (9600, N, 8, 1, ID 1) to communicate with the master station.
When INIT and DGND pin is disconnected, the module will use user-defined parameters to communicate with the master station.
