Example
The following example represents a possible Route Information Packet. A device receives the packet
when it performs a trace route on a transmission from one device (serial number 0x0013A200
4052AAAA) to another (serial number 0x0013A200 4052DDDD).
This particular frame indicates that the network successfully forwards the transmission from one
device (serial number 0x0013A200 4052BBBB) to another device (serial number 0x0013A200
4052CCCC).

0x12 = Trace route
5
The number of bytes that follow, excluding the checksum. If the
length increases, new items have been added to the end of the list
for future revisions.
6-9
System timer value on the node generating the Route Information
Packet. The timestamp is in microseconds. Only use this value for
relative time measurements because the time stamp count restarts
approximately every hour.
The number of MAC ACK timeouts that occur.
10
The number of times the transmission was blocked due to reception
11
in progress.
Reserved, set to 0s.
12
The address of the final destination node of this network-level
transmission.
21-28
Address of the source node of this network-level transmission.
29-36
Address of the node that generates this Route Information packet
after it sends (or attempts to send) the packet to the next hop (the
Receiver node).
37-44
Address of the node that the device sends (or attempts to send) the
data packet.
