Send binary commands

Example

Use XCTU's Serial Console tool to change the device's DT (Destination Address) parameter and save the new address to non-volatile memory.

This example requires XCTU and a serial connection to a PC.

To send binary commands:

  1. Set the RT command to 1 to enable binary command programming; do this in Command mode or configure it through XCTU.
  2. Drive pin 29 high to assert CMD by de-asserting the RTS line in XCTU. The device enters Binary Command mode.
  3. Send hexadecimal bytes (parameter bytes must be 2 bytes long). The next four lines are examples, not required values:
    00 (Send binary command DT)
    0D (Least significant byte of parameter bytes)
    1A (Most significant byte of parameter bytes)
    08 (Send binary command WR)
  4. Drive pin 29 low to de-assert CMD. After you send the commands, CTS (pin 25) de-asserts (driven low) temporarily. The device exits Binary Command mode.

The default flow control is NONE, so if you are using XCTU, CTS is not an issue. However, you can still observe the behavior of the CTS line by monitoring the CTS indicator in the terminal or console.
