Remote Out-of-Band Access in the World’s Deepest Underwater Observatory

(thanks to by Brian Chee, Senior Contributing Editor, InfoWorld Test Center)

Imagine the world’s deepest observatory at 3 miles below the sea surface. Now think about what a challenge it would be to monitor equipment for such a remote location. This was the problem encountered by Aloha Cable Observatory (ACO), as they sought to replace an old power distribution unit (PDU) with a solution that would supply remote power management, control and configuration for critical seawater systems.

Enter SLB! The Secure Lantronix Branch (SLB) Office Manager from Lantronix was selected to securely manage remote servers and IT infrastructure equipment over the Internet and control devices that only had serial remote access. ACO technical staff deployed SLB to perform last-resort power reboots of various control computers in the power and control section of the dry land portion of ACO.

“We needed to replace a failing PDU that was too old to provide encrypted remote access – an issue that threatened to put us in violation of acceptable use policies,” said Brian Chee, IT specialist, University of Hawaii at Manoa. “The SLB solved that issue while supplying more control in less rack space since the SLB provides the functionality of three different devices in a single RU.”

SLB provided ACO with secure, remote out-of-band access while offering more flexibility and power control. If SLB can accomplish these feats 3 miles under the surface of the ocean, think about what it could do for your business!

Sending data from Lantronix to Google Analytics

Google and Lantronix

The following is a copy of a guest post from Kurt Busch, CEO, and Mariano Goluboff, Principal Field Applications Engineer at Lantronix as originally posted on Google’s corporate blog at:


Google Analytics makes it easy to create custom dashboards to present data in the format that most helps to drive business processes. We’ve put together a solution that will make several of our devices (networking and remote access devices) easily configurable to enable delivery of end device data to Google Analytics. We use the Lantronix PremierWave family of devices to connect to an end device via a serial port like RS-232/485, or Ethernet, intelligently extract useful data, and send it to Google Analytics for use in M2M applications.

What you need

To get started, grab the Pyserial module, and load it on your Lantronix PremierWave XC HSPA+. You’ll also want a device with a serial port that sends data you want to connect to Google Analytics. A digital scale like the 349KLX is a good choice.

Architecture overview

With the Measurement Protocol, part of Universal Analytics, it is now possible to connect data from more than web browsers to Analytics.

Lantronix integrated the Measurement Protocol by using an easy to deploy Python script. By being able to natively execute Python on PremierWave and xSenso devices, Lantronix makes it very easy to deploy intelligent applications leveraging Python’s ease of programming and extensive libraries.

The demonstration consists of a scale with an RS-232 output, connected to a Lantronix PremierWave XC HSPA+. The Python script running on the PremierWave XC HSPA+ parses the data from the scale, and sends the weight received to Google Analytics, where it can then be displayed.

The hardware setup is show in the picture below.

The technical details

The Python program demonstrated by Lantronix uses the Pyserial module to parse this data. The serial port is easily initialized with Pyserial:

class ser349klx:
# setup the serial port. Pass the device as '/dev/ttyS1' or '/dev/ttyS2' for
# serial port 1 and 2 (respectively) in PremierWave EN or XC HSPA+
def __init__(self, device, weight, ga):
  while True:
    serstat = True
    ser = serial.Serial(device,2400, interCharTimeout=0.2, timeout=1)
   except Exception:
    serstat = False
   if serstat:
  self.ser = ser
  self.weight = weight = ga

The scale used constantly sends the current weight via the RS-232 port, with each value separated by a carriage return:

def receive_line(self):
  buffer = ''

  while True:
   buffer = buffer +
   if '\r' in buffer:
    lines = buffer.split('\r')
    return lines[-2]

The code that finds a new weight is called from a loop, which then waits for 10 equal non-zero values to wait for the weight to settle before sending it to Google Analytics, as shown below:

# This runs a continuous loop listening for lines coming from the
# serial port and processing them.
def getData(self):
  count = 0
  prev = 0.0
  #print self.ser.interCharTimeout
  while True:
    val = self.receive_line()
    if (prev == weight.value):
     count += 1
     if (count == 10) and (str(prev) != '0.0'):"{:.2f}".format(prev))
     count = 0
     prev = weight.value
   except Exception:

Since the Google Analytics Measurement Protocol uses standard HTTP requests to send data from devices other than web browsers, the ga.send method is easily implemented using the Python urllib and urllib2 modules, as seen below:

class gaConnect:
def __init__(self, tracking, mac):
  self.tracking = tracking
  self.mac = mac
 def send(self, data):
  values = { 'v' : '1',
     'tid' : self.tracking,
     'cid' : self.mac,
     't' : 'event',
     'ec' : 'scale',
     'ea' : 'weight',
     'el' : data }
 res = urllib2.urlopen(urllib2.Request("",

The last piece is to initialize get a Google Analytics connect object to connect to the user’s Analytics account:

ga = gaConnect("UA-XXXX-Y", dev.mac)

The MAC address of the PremierWave device is used to send unique information from each device.


With these pieces put together, it’s quick and easy to get data from the device to Google Analytics, and then use the extensive custom reporting and modeling that is available to view the data. For example, see the screenshot below of real-time events:

Using Lantronix hardware, you can connect your serial devices or analog sensors to the network via Ethernet, Wi-Fi, or Cellular. Using Python and the Google Analytics Measurement Protocol, the data can be quickly and easily added to your custom Google Analytics reports and dashboards for use in business intelligence and reporting.

Lantronix + dweet + freeboard: Connecting a microcontroller’s serial port to the Internet of Things

XPico Wi-Fi Freescale Tower ModuleTalking to my customers, everybody is asking about the Internet of Things. There is so much information about the IoT, that it can be confusing to figure out how to solve your specific business problem with all the options available.

Where the rubber meets the road is putting hardware, software, and services together to get to a cogent solution. All while reducing costs and time to market, of course. So when I heard someone wanting to connect to Bug Labs’ I was intrigued. Here’s a service that claims to make the sending of data very easy. I don’t even have to sign up for a free account, I can just start sending data from my device? Let’s try this out.

I took a Lantronix xPico Wi-Fi Freescale Tower System connected with a Kinetis microcontroller. The xPico Wi-Fi manages the TCP connection to the server, so the microcontroller only needs to construct the message to be sent. The platform accepts data with standard HTTP requests, so the microcontroller just sends the following data to the UART port, and the rest is taken care of by the xPico Wi-Fi.

GET /dweet/for/<uid>?potentiometer=<value> HTTP/1.1\r\n
Connection: keep-alive\r\n
Accept: */*\r\n

The program running on the microcontroller sends new data any time that the potentiometer on the Kinetis Tower board changes. This video shows how it works:

Using, it couldn’t have been easier to view the information being posted. In literally 5 minutes, I had a dashboard that shows current and historical data:


There are many services and products to help get your device connected to the Cloud. Lantronix hardware and the software applications that run on it make it very easy to connect your device to the network. The and services from Bug Labs can take the data from the device and make it actionable quickly.

Figuring out how to use the Internet of Things to your advantage doesn’t have to be complicated. We can help you design and implement a total solution of hardware, software, and services to meet your needs.

xPrintServer: On the Road, Online, On TV, and In Print

Launching a new product is never easy, and it can even be more challenging when the product is one of a kind. It takes creativity, out of the box thinking, lots of elbow grease, a little bit of luck and persistence.

Little more than a year after its launch, you’d be hard pressed to find an iPad or iPhone enthusiast who has not heard about xPrintServer. While this product line – and the market opportunity for networked mobile printing– is in many ways still in its infancy, xPrintServer is well positioned to capitalize on the need for a cost-effective and easy to deploy networked mobile printing solution as more and more businesses adopt iPads in the workplace.

Our latest marketing blitz hit the market back in early November 2012, in preparation for holiday gift guides and promotions.

Lantronix and the xPrintServer were featured in more than a dozen national morning show segments on NBC, CBS, ABC, CNBC and more – thanks to Steve Greenberg, author of Gadget Nation and host of the TV show “Invention Hunters.”  From Chicago, Minneapolis, and Washington, to New York, Seattle, and Houston, the gadget-shows were seen by mobile Apple device users nationwide!

Key to holiday marketing success are “holiday gift guides” – and xPrintServer proved to be a popular stocking stuffer this year.  From British Airways in-flight magazine (Business Life) to Electronic House’s Back to School Cool list to Cult of Mac’s iPad Lover’s Gift Guides, we appeared in more than a dozen magazine and online guides. The result was that in the December quarter, Lantronix recorded increased sales in our device management product category – most of the growth in sales due to the xPrintServer product’s growing popularity.

Holiday Gift Guides and xPrintServer

Following our success formula from last year, we once again leveraged CES and MacWorld as platforms for launching and promoting the xPrintServer.  Prior to the events, we demonstrated the xPrintServer (Office and Home editions) to more than 1,000 members of the U.S. and EMEA press.   To complement the resulting hundreds of pieces of press coverage and product reviews, we also hit the market with print and online ads, building momentum for the live events.   MacWorld, iPhoneLife, MacDirectory, iBusiness Magazine, Network World,  and more all featured one to two page print ads – distributed and mailed to more than 2 million iPad and iPhone enthusiasts – from on-site distribution at CES and MacWorld, to newsstands, airports and electronics stores nationwide.  Not to be outdone by the xPrintServer, our president and CEO Kurt Busch and the Lantronix M2M story made the cover and feature story in EEWeb’s latest Pulse Magazine.

i.Business Magazine + Legacy Series Special Edition

To complement the on and off line print ads, the Lantronix xPrintServer took to social media.  Our award-winning “I Can Print!” commercials have been aired on CNBC and Google’s online network of video sites, on YouTube, and even made it to a premier showing during Fashion Week in Toronto.  To further capture gadget and trend influencers, xPrintServer is being featured on the new OraTV channel – exposing the brand to more than 1 million viewers in March and April of 2013.   No online or social media effort would be complete without the endorsement of technology guru Leo Laporte (go to minute marker 16.00) and his team’s support of the xPrintServer, which was highlighted on several dozen TWiT.TV podcasts over the past six months.
