Is there a location To find proper wiring configuration for these two boards ( other than the circuit boards themselves ) ? I fear they may be configured incorrectly for the serial port of BSS BLU 100 . Not responding to logic

Should be:

  • - VCC--VCC
  • - GND--GND
  • - RX--TX
  • - TX--RX

    • Double check the pinout on your device as well, you might need a null modem between the shifter and your device.
