WI.USB-DTS-R DATASHEET
5. Notes
5.1. Microsoft/ Hilgraeve HyperTerminal
The Wi.USB-DTS-R™ 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. In the Wi.USB-DTS-R™, the RTS line is tied to the CMD pin on the module inside the Wi.USB-DTS-R™.
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 a Wi.USB-DTS-R™ is powered 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 Wi.USB-DTS-R™ with HyperTerminal or other terminal program, you must remove the cover, locate
the jumper “JP2”, and remove it. Removing this jumper will disconnect the RTS line from the CMD pin on the
Wi.232DTS-R™ module inside, allowing normal operation. It must be noted that while this jumper is removed,
commands cannot be sent to the Wi.USB-DTS-R™. Everything sent to the Wi.USB-DTS™ will be sent over RF.
