  • Page 10: Overview

    When properly configured and installed, long range communications at very high speeds can be achieved. Pico P2400 Series modules are a 2.4 GHz Frequency Hopping modem, providing flexible wireless data transfer between most equipment types which employ a serial interface. The modem type of the module is software selectable using AT commands.
