Particle XBridge How-To

Please see our Particle How-To page for an overview as well.

Here is our page on the XBridge infrastructure at hcilab.org.

Before starting, make sure that your XBridges do have the necessary software and firmware running on them. See the first link of the references for a detailed XBridge upgrade how-to. On the TecO pages, there is also the C code for the XBridge Particle.

Basic Configuration

There are several methods for initially configuring the XBridges.

Lantronix Device Installer

The latest version of the Lantronix Device Installer for configuring the XPort on the XBridge can be found at http://www.lantronix.com/device-networking/utilities-tools/device-installer.html. We sometimes experienced problems using this tool, so we recommend using the telnet configuration using the device IP and Port 9999. A detailed setup guide on how to use the Lantronix utility can be found on the TecO page on the XBridge configuration.

Telnet Configuration

We prefer to configure the XBridges using telnet. For this, open a telnet program and connect to the XBridge IP using port 9999.

 

Problems

The XBridge cannot be found when plugging it into a different network?!

  • Plug both your computer and the XBridge into one network hub/switch/.... Don't connect the hub to the new network. Configure your computer's network to use the IP and subnetmas you used when the XBridge was working in your home network.
       
     
  • Now you should be able to connect to the bridge by telnet (see description above). Configure the Server Address to be the new settings (new local IP address, ...).
  • Save and exit.
  • Connect again by telnet and configure the broadcast address to be 255.255.255.255.
  • The connection will probably be terminated, otherwise save and exit.
  • Plug your computer and the XBridge (or the hub) into the network. You should now be able to find the XBridge with the Lantronix Device Installer or connect to it with telnet.


The LEDs on the XBridge are going havoc?!

  • Green: flashing means the PIC on the FIFO board is running.
  • Red: either the input or output buffer (one LED for each buffer) of the FIFO experienced an overflow. The LED will be then permanently on to indicate this situation.
  • Yellow: error in the serial communiation between XPort and FIFO board (probably a misconfiguration of the serial speed on the XPort -> telnet and check for entry 1 in the menu)
  • Blue: data transfer between XPort and FIFO board (one LED for each direction). The LEDs will flash sometimes very short.
