FHSS Transmit Diagnostic switches on the transmitter in Frequency Hopping mode, using the hop set
and power mode selected. A “…1010101010101…” bit pattern is transmitted. This mode cannot be used
as an excitation source for the receive diagnostic and is provided for testing purposes only.

The RK-Wi.232FHSS Evaluation Kit can be used with HyperTerminal to receive and transmit RS-232 data
and send files using file transfer protocols such as ZMODEM. HyperTerminal and many other terminal
programs assert RTS by default. On the evaluation board, the RTS line is tied to the CMD pin on the
module. When the CMD pin is held low, which is the case when the RTS line is asserted, the module will
be placed in command mode.
In command mode, all UART data sent to the module will be interpreted as commands and will NOT be
sent to the RF engine for transmission. Additionally, if an evaluation board is switched on in the presence
of an asserted RTS line, it will perform a full hardware and flash reset to the factory defaults.
To use the evaluation board with HyperTerminal or other terminal program, you must first remove the
jumpers from pins 7+8 of JP2, if you are using an RS-232 connection to your PC, or JP3, if you are using
a USB connection to your PC. Removing this jumper will disconnect the RTS line from the CMD pin on
the module, allowing normal operation.
