Replace Nodes; Test Links Between Adjacent Devices - Digi DigiMesh XBee S2C User Manual

Network commissioning and diagnostics
2. All of the nodes internally update only their routing table information to contain a route to the
aggregator node.
3. None of the nodes update their DH and DL registers because none of the registers are set to
the 0xFFFE address.

Replace nodes

You can use the AG command to update the routing table and DH/DL registers in the network after
you replace a device. To update only the routing table information without affecting the DH and DL
registers, use the process in example two, above.
To update the DH and DL registers of the network, use example three, below.
Example three:
This example shows how to cause all devices to update their DH and DL registers to the MAC address
of the sending device. In this case, assume you are using a device with a serial number of 0x0013A200
4052C507 as a network aggregator, and the sending device has a MAC address of 0x0013A200
F5E4D3B2 To update the DH and DL registers to the sending device's MAC address:
1. Replace the aggregator with 0x0013A200 F5E4D3B2.
2. Send the ATAG0013A200 4052C507 command to the new device.

Test links between adjacent devices

It often helps to test the quality of a link between two adjacent modules in a network. You can use the
Test Link Request Cluster ID to send a number of test packets between any two devices in a network.
To clarify the example, we refer to "device A" and "device B" in this section.
To request that device B perform a link test against device A:
1. Use device A in API mode (AP = 1) to send an Explicit Addressing Command (0x11) frame to
device B.
2. Address the frame to the Test Link Request Cluster ID (0x0014) and destination endpoint: 0xE6.
3. Include a 12-byte payload in the Explicit Addressing Command frame with the following format:
Number of
bytes Field name
8 Destination
address
2 Payload size
2 Iterations
4. Device B should transmit test link packets.
5. When device B completes transmitting the test link packets, it sends the following data packet
to device A's Test Link Result Cluster (0x0094) on endpoint (0xE6).
6. Device A outputs the following information as an API Explicit RX Indicator (0x91) frame:

Description
The address the device uses to test its link. For this example, use the
device A address.
The size of the test packet. Use the NP command to query the
maximum payload size for the device.
The number of packets to send. This must be a number between 1 and
4000.
