CDBUS Bridge

cdbus_bridge

cdbus_bridge_pcb

CDBUS Bridge has two types of communication ports, which are 3 serial ports and 2 RS485 ports:

  • Only one of the three serial ports will be in use at the same time. Inserting USB will switch over to the configuration-free USB serial port (the communication rate will not be affected by the selected baud rate);
  • The two RS485 ports are internally connected for easy wiring (or pull up, pull down, and termination resistors).

The CDBUS Bridge has two modes, which are selected by the switch:

Bridge Mode (Serial to RS485)

bridge_mode

Raw Mode (Serial passthrough)

raw_mode
