The MSP-TRF4903-DEMO kit is preconfigured to function under the following assumptions:
•
North American ISM frequency band, 902-928 MHz
•
NRZ (non-return to zero) coding
•
FSK (frequency shift keying)
•
38.4 Kbps
•
On-board PCB antenna
The kit can be reconfigured to a limited extent. These options are covered in this section.
