  Product BOB-09822 about 8 years ago

  I bought 1 SparkFun FTDI Basic Breakout - 3.3V, 1 SparkFun Transceiver Breakout - RS-485 and 1 SparkFun USB to RS-485 Converter .

  I connect:

  PC1 -> FTDI Basic Breakout -> Transceiver -> USB to RS-485 -> PC2.

  To communicate PC1 to PC2, I connect TXDEN (FTDI Basic Breakout ) to RE/DE (Transceiver). If I send "Hello PC2" message, in PC2 I receive " Hello PC2<0>".

  To communicate PC2 to PC1, if I send "Hello PC1" message, in PC1 I receive " Hello PC1" but in PC2 I receive many bytes of trash. The same trash come if RS485 modules are not connected.

  I suspect that SparkFun USB to RS-485 Converter is damaged, but its new...

  Anyone else had this issue?

No public wish lists :(
