DH (Destination Address High)

This command applies to the XBee 3 802.15.4 RF Module.

Set or read the upper 32 bits of the 64-bit destination address.

When you combine DH with DL, it defines the 64-bit destination address that the device uses for outgoing data transmissions in Transparent mode (AP = 0) and I/O sampling. This destination address corresponds to the serial number (SH + SL) of the target device.

To transmit using a 16-bit address, set DH to 0 and DL less than 0xFFFF. When associating to a coordinator as an end device (CE = 0, A1 | 0x04), the destination address is automatically set to address the coordinator.

Reserved 802.15.4 network addresses:

• 0x000000000000FFFF is a broadcast address (DH = 0, DL = 0xFFFF).

Parameter range

0 - 0xFFFFFFFF

Default
