Linux and Mac OS X drivers

The native USB drivers for Linux and Mac OS X have merged into a single driver: the Exodriver. Download the Exodriver source code from GitHub, and refer to the README and INSTALL files for more information. Note that the Exodriver is built on libusb-1.0, which can be downloaded from SourceForge.

Mac OS X users can use the pre-built installer rather than building the Exodriver from the source. The installer includes an unmodified copy of libusb 1.0.6 (source code). We also provide a simple Xcode project to make getting started with the Exodriver easier.

Python

LabJack actively develops Python code to communicate with its devices.

If you’re new to Python, start with Dive Into Python. It’s great.

If you know Python and want an easy way to talk to you LabJack, start with our Python module, LabJackPython.

FAQ

Modbus

tags:

Modbus is an industry standard command-response protocol for data acquisition and control equipment. This document assumes that the user is either familiar with the Modbus protocol or a software package which handles most of the Modbus details is being used. For detailed information about Modbus, visit the Modbus website.

Beta Modbus support was first added to the UE9 with comm. firmware 1.41 and control firmware 1.70. Both the control and comm. firmware are required for Modbus functions. The U3, U6, and UE9 all support Modbus over USB. Upgrade to the latest firmware for the best support.

Modbus Map

We've made the latest Modbus map available as a spreadsheet (opens in new window). The spreadsheet may refer to alpha, beta, or unreleased firmware. Contact us for assistance.

Firmware

All LabJack devices, except the U12, have upgradable firmware. From time to time, we release a new firmware to fix any issues that are discovered or add new features.

You can find all firmware files at firmware.labjack.com.

To upgrade the firmware on Windows, please use LJSelfUpgrade that comes bundled with the installer for the UD driver. The LJSelfUpgrade download provided here is a newer version than the one bundled with the latest installer. In order to run, LJSelfUpgrade version 1.24 requires the installation of UD driver 3.15 on your system.

Linux and Mac users, or adventurous Windows users, can use a Python firmware upgrader for Python 2.5. (For Python 2.6) If you have UE9 Control firmware older than 1.78, you must use LJSelfUpgrade.

Windows, Linux, and Mac OS X users can all use CloudDot Grounded to upgrade LabJack firmware.

Note: The Python Firmware Upgrader requires httplib2. It can be downloaded from its Google code page. Python 2.5 also requires simplejson, which can be downloaded here.

SkyMote

 

New SkyMote family.

Bridges:
SMB-ETH SkyMote Ethernet Bridge (Spring 2010)
SMB-USB SkyMote USB Bridge (Spring 2010)
SMB-REP SkyMote Repeater (Spring 2010)

Motes:
SM-TLB Temp/Light/Bump SkyMote (Spring 2010)
SM-TLB-RH Temp/Light/Bump plus Humidity SkyMote (Availability TBD)
SM-DVM Digital Voltmeter SkyMote (Availability TBD)

SkyMote devices create a 2.4 GHz 802.15.4 based Wireless Sensor Network (WSN).  Our network has control capability also, so Wireless Sense & Control Network (WSCN) might be a better term.

All wireless communication is secured with 128-bit AES encryption.  A password can be used to lock a mote so it will not join unauthorized networks.

A SkyMote network has a tree topology:

 

 

Bridge:  A bridge is used to connect the wireless network to a host via Ethernet or USB.  Each network has only 1 bridge.  The wireless tranceiver on a bridge is always on.  A bridge can have up to 16 children (repeaters and motes).

Repeater:  Creates a wireless link between 1 parent and up to 16 children.  The wireless tranceiver on a repeater is always on.

Mote:  End-device with sensors and actuators.  Generally operated in sleeping mode, where the device (including wireless transeiver) is shut down most of the time, and wakes up periodically.  A sleeping mote cannot have children.

 

The network device limit (bridge + repeaters + motes) is currently set at 128.
