5. Notes
5.1. Microsoft/ Hilgraeve HyperTerminal
5.2. Loopback Mode
The RK-Wi.232DTS-FCC-R 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 moduSle 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.
The RK-Wi.232DTS-FCC-R kit can be operated in a loopback mode by configuring the COM jumpers in such
a way as to link together the TXD and RXD lines to and from the module in the remote evaluation board.
Using this mode, the user can send data from their local
evaluation board and have it re-transmitted back to them
by the remote evaluation board. The maximum baud rate
allowed in loopback mode is 38400 baud for point to
point communications only.
