MXR-505 Communication
Communication with the MXR-505 is accomplished through a universal asynchronous receive/
transmit (UART) peripheral interface. The UART uses 8-bit, non-parity, LSB, 1200bps baud
format. The maximum number of data bytes that can be transmitted or received in one packet is 50.
The user will transmit data through the UART on the MXR-505 via pin 24, URXD. The MXR-505
will packetize and wirelessly transmit the data. Once the data is received on the other side, the
MXR-505 will demodulate the data and send the received data out to the user via pin 23, UTXD.
The data being sent through the UART should follow a specific protocol.
The communication protocol is outlined below:
Byte #1
Number of Bytes – The number of bytes is one byte containing the total number of
data bytes. This byte should not be included in the number of bytes. Therefore, the
number of bytes should be one less than the total number of bytes being sent or
received. The maximum number of data bytes that can be transmitted or received is
50; therefore, the number of bytes should not exceed 50.
Bytes #2-51
Data Bytes – The data bytes are the actual data byte values being transmitted or
received by the MXR-505. The MXR-505 can send or receive a maximum of 50
data bytes per packet. The first two bytes are used as preamble bytes by Radios,
Inc. to differentiate the detection of data from noise. They can be set to any value,
but to work with the HHDS-ML they must be set to 0xFF and 0x00, respectively.
When the first byte is received through the UART on the MXR-505, the user will have one second
to send the remaining data bytes to the MXR-505. If the MXR-505 does not receive all of the data
bytes within that second, the data the MXR-505 did receive will be dumped. For example, if the
user sends a 10 for the number of bytes and then only sends five more bytes within one second, the
MXR-505 assumes this is corrupted data and does not transmit the packet. The five bytes the
MXR-505 did receive will be discarded and the MXR-505 will wait for a new packet of data to be
received.
