Inputs

  • IN_A: OUT_A - Outgoing data on channel A
  • IN_B: IN_A - Incoming data on channel A
  • IN_C: SWITCH - a HIGH signal switches the output relay ON and connects the outputs to the connector
  • IN_D: ID - Used to set the module ID
  • IN_E: CTRL_B - A HIGH signal sets channel B to an output and a LOW signal sets it to an input
  • IN_F: CTRL_A - A HIGH signal sets channel A to an output and a LOW signal sets it to an input
  • IN_G: OUT_B - Outgoing data on channel B
  • IN_H: IN_B - Incoming data on channel B

Outputs
