Reconfiguring a USB coordinator

This procedure is to reconfigure a USB coordinator (wireless Sedona Framework Jennic USB adapter) that was previously added using the New Jennic Wireless Adapter tool in Workbench (see Installing a new USB coordinator (New Jennic Wireless Adapter) for related details). The Jennic Serial Port Tool lets you change its Jennic PAN Id and channel, as well as its Diag Level (level of debug messaging output to Workbench’s console window).

Reconfigure USB coordinator

You may need to reconfigure a USB coordinator’s Panid and/or channel so it can communicate to some new Jennic-based device, or to a device with its Panid changed (perhaps from loading its “fallback app”).

  1. Insert the USB coordinator into a USB 2.0 port on the Workbench PC, if not already inserted.

  2. From the Workbench menu bar, select Tools->Jennic Serial Port Tool.

    The tool’s “Configuration View” displays, with Ports shown in the top pane “Port table”.

    NoteIf no ports are listed, the tool is stopped. Click the start control to start it, so ports list in the table. The USB coordinator LED remains blinking blue at a fast rate if it is stopped (not ready to run a network), or else blinks green, at a one second rate if it is ready and available for network connections from Jennic-based Sedona Framework devices.

  3. Click the COM port row of type adapter.

    The firmware version number and (editable) configuration of the coordinator appears in the view.

  4. As needed, change one or more properties, described as follows:

    • Panid

      Jennic PAN ID (Personal Area Network identifier), in hexadecimal, range 0x0000 to 0xFFFE for the network. The wireless USB adapter acts as the Jennic coordinator for this network.

      CautionDo not use the identical Panid as any other nearby Jennic coordinator, for example a JACE with Sedona Jennic option card. This applies if using Niagara Workbench enabled for Sedona Framework TXS, and you have such a JACE as well as a USB coordinator. Each coordinator must use a unique Panid.

    • Channel

      RF 2.4GHz channel number to use, from 11 to 26.

    • Diag Level

      Level of Jennic/Sedona-related debug messaging to include in the Workbench console window, where value of 0 provides the smallest level. See the Getting Started with the Sedona Framework Developer Kit document for related details.

    NoteChanging the value of the coordinator’s Panid or Channel, after a save, causes a restart of the coordinator.

  5. Click the Save button to make changes effective.

    A popup Writing Jennic Network Config dialog briefly appears, showing progress in writing to and then (typically) restarting the coordinator. During this time, LED activity on the USB coordinator changes color (blue, red) and blink pattern before returning to green, at one second rate.

  6. When the coordinator restarts, it sends a beacon message out on the wireless network. Devices that are configured to use that PAN ID (and include that channel in their channel map) should respond within a minute or so—and appear “ghosted” in Workbench’s Nav tree, listed by IPv6 address.

    To Sox connect to such a device, right-click it and select Open Sedona (sox), and in the Open Sedona popup dialog, enter its credentials (Username and Password).

Note other buttons are available in the Configuration View of the Jennic Serial Port Tool. For related details, see Buttons.
