  • Page 21: Quickstart

    If the module is connected to a PC or non 3.3 Volt logic level, a converter cable/IC (e.g. 3.3 V TTL to USB) is necessary to achieve interface compatibility. The Themisto-I-EV already im- plements such a USB converter to be connected to a PC. Not interpreting the /RTS line of the module as described in this manual may cause undefined behavior and data loss.

Quickstart example Sending and receiving: Hello World Connect the two devices (modules, EV-boards or USB dongles) to a PC. You may need to install FTDI VCP drivers manually (see FTDI) or using windows update. A minimum distance of 2 meters between the two devices should be kept at all time to avoid over modulation of the receiver.
