True RS232 IR

Our true RS232 IR products are arduino based and allow you to send or receive infrared codes via a true RS232 Serial port or USB emulated serial port. This allows for IR transmission and reception without specialized software like LIRC. Commands can be sent via hex code or raw codes. On the receive side we can provide hex codes, raw codes, or a unique hash.

 IR Codes are sent with the following command set: IR_CODE_TYPE,IR_CODE_LENGTH,IR_CODE_HEX_DATA

The following values are acceptable for IR_CODE_TPYE:

  - NEC
  - SONY
  - RC5
  - RC6
  - PANASONIC_OLD
  - JVC
  - NECX
  - SAMSUNG36;
  - GICABLE
  - DIRECTV
  - RCMM
  - CYKM
