Note: The CTS signal needs to be activated in order for the fastening data to be output. If it is
not activated, up to 16KB of data will be stored in the output buffer. Once the buffer is full, the
data will be overwritten in a First In, First Out (FIFO) process. The CTS signal may be con-
nected to the RTS signal if data is to be “dumped” at every fastening.
