rs485 sniffing |

Hi everyone. I have a piece of hardware that continuously sends data using rs485 communication protocol. What I want to do is get the data that it is sending, my problem is that I don't know what address it sends its data. The code I have can only get the data if it knows the address beforehand. Is there a way to get around this problem? Please help. Thanks in advance. |

If the transmitted data is ASCII I make a RS485 monitor with the receive half of a 485 transceiver and send the resulting TTL output to a serial com port and a terminal monitor program like teraterm or hyperterminal. You will see everything transmitted on the 485 bus. |
