EWD-900-HDTC 128 Channel FSK Data Transceiver
Data Sheet
A unique feature of the module is the on-board EEPROM. The EEPROM contains a
unique 32-bit serial number and calibration data. The calibration data is used to correct
for frequency errors generated by the crystal and by temperature deviation from 25
degrees C. For more information on using information from the EEPROM, please refer
to “EWD-HDTC USER’S MANUAL”.
The EWD-HDTC provides a very simple microcontroller interface. The module is
programmed by a 3-wire serial interface, and data is sent and received to and from the
module using a 2-wire serial interface. The RSSI pin provides an analog voltage that is
proportional to the incoming received signal in dB.
Programming the EWD-HDTC is very simple. We provide a complete API for most
microcontrollers that is written in C. For details on the API please refer to “EWD-HDTC
USER’S MANUAL”.
