4.2.2 Receive
Diagnostic
Receive Diagnostic consists of four radio buttons which allow the selection of frequency, the “Set RX
Diag” button which activates the module’s receiver and begins a bit error test, and the result box, which
shows the number of bit errors recorded in the last test.

shows the number of bit errors recorded in the last test.
The “Set RX Diag” button switches on the receiver using the channel and mode selected in the channel
selector and transceiver mode controls. The module stops hopping frequency and stays stationary. It will
wait for a “10101010...” bit pattern at the RF interface. If one is not received, the module could remain in
an infinite loop waiting for this start condition. If this happens, simply cycle the power to return the
module to normal operation.

The Receive Diagnostic mode can be used in conjunction with another module operating in “Tx 1-
Channel Diag” mode. Both transmitting and receiving modules must be on the same frequency and have
the same baud rate selected for proper operation of the bit error test.

5 Notes
5.1 Microsoft Windows / Hilgraeve HyperTerminal
The RK-Wi.232FHSS-25-FCC
™ 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.
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.

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.
