4.1. Addressing
Each RF packet contains addressing information that is used to filter incoming RF data. Receiving
modules inspect the Hopping Channel (HP parameter), Vendor Identification Number (ID parame-
ter) and Destination Address (DT parameter) contained in each RF packet. Data that does not pass
through all three network security layers is discarded.

4.1.1. Address Recognition
Transmissions can be addressed to a specific module or group of modules using the DT (Destina-
tion Address) and MK (Address Mask) commands. A receiving module will only accept a packet if it
determines the packet is addressed to it, either as a global or local packet. The receiving module
makes this determination by inspecting the destination address of the packet and comparing it to
its own address and address mask [refer to the figure below].

TX_DT ? = ? Destination ? Address ? of ? transmitting ? module
RX_DT ? = ? Destination ? Address ? of ? receiving ? module
RX_MK ? = ? Address ? Mask ? of ? receiving ? module
RX_MY ? = ? Source ? Address ? of ? receiving ? module ?
The transmitting module determines whether the packet is intended for a specific node (local
address) or multiple nodes (global address) by comparing the packet's destination address (DT)
and its own address mask (MK) [refer to the figure below]. It is assumed that the address masks
on the transmitting module and receiving module have been programmed to the same value for
proper operation in each RF Communication Mode.
