How to connect

Connect the master and slave devices by setting jumper pins for each pattern of power supply and signal voltages on the master and slave sides as shown below.

• ① Power: 5V, Signal: 5V → Power: 3.3V, Signal: 3.3V
  • Power supply voltage conversion direction selection jumper (J4・J5): 5V->3V3
  • Signal voltage selection jumper of 5V system side (J9): 5V
    
    
    
• ② Power:5V, Signal:3.3V→Power:3.3V, Signal:3.3V
  • Power supply voltage conversion direction selection jumper (J4・J5): 5V->3V3
  • Signal voltage selection jumper of 5V system side (J9): 3V3
