How the Dual-PAN works

• Maintains two sets of network parameters − PAN, MAC address, Network Address, Operation Channel

• Supports manual and automatic modes for switching between networks − Manual – controlled by software

− Auto – controlled by hardware

• Device can function as a coordinator, router or end device on each network.

External Use 28

Dual-PAN in Multiple Channels

2 PANs, 2 Channels

• Time to dwell on channel can be set from 0.5 ms to 3.2 seconds

− Dwell prescaler and dwell selector registers

• If PAN is active when timer expired, sequence will complete before

channel switch occurs

• Channel switch is 68 us

• Time to switch, poll, receive packet and switch back is <10ms

2 PANs, 1 Channel

• Address filtering is done simultaneously

• No channel switch is necessary
