5. Communications
6. Device Command overview
The RFID modules are configured by means of using a TTL level RS232 bus. This protocol requires a start bit, eight
data bits and a stop bit.
The baud rate for the modules is set to 9600, with no parity, and there is also a flow control, CTS, line that can be
used.
Here is a functional diagram of the timing required by the RFID modules. The module is ready to receive data when
the CTS line drops to logic zero. After sending the data you have to then wait at least 100ms before data will be
transmitted back from the module.
