• Manufacturer Part Number: RPC-UHF
• Description: Radio Packet Controller
• Manufacturer: RADIOMETRIX [Radiometrix Ltd]

Data is transferred between the RPC and the H
asynchronous protocol. The nibbles are always sent in pairs to form a byte, the Least Significant
Nibble (bits 0 to 3) is transferred first, followed by the Most Significant Nibble (bits 4 to 7). Two pairs
of handshake lines, R
