The USB-microDig is a thumb-sized easily configurable
hardware device that encodes upto 8 analog sensor and 8 digital actuator signals with high resolution using a variety of globally compatible digital protocols and transmits these messages through USB to any computer in real-time, where they are made available at a virtual serial port for analysis and/or control purposes.
Sensitive in real-time
It has 8 inputs of each 10 bits resolution (1024 steps of each 4.9 mV) that can sample at upto 5760 Hz with milliseconds latency to capture even the finest gestures and movements. Use it conveniently with our
sensors to create your interactive installation, ultimate controller, .. For hardware hackers, the USB-microDig features a hardware hacking area to add your own sensor circuit.
It's updateable firmware v7.1 enables it to operate in both "standalone" mode (sensor data is processed before it is transmitted through the USB cable) as well as host mode (raw sensor data is transmitted through the USB cable). Standalone mode includes various sensor processing and mapping features such as gesture recognition that can be conveniently configured using one of our editors. Configure it with the editor and it will remember the settings after power down (ie. unplugging it from the USB port). If you need raw sensor data or if you need more sensor mapping or analysis complexity, use it in host mode in combination with a programming or analysis environment to process the sensor data.
Compatible and versatile
Even though it encodes analog (0-5V) sensor signals to multimedia industry compliant MIDI messages, you don't need a MIDI interface to receive them. First, it transmits the MIDI messages through USB, which is a common and reliable protocol. The USB communication complies with the USB v2.0 (upto 480 Mbps) and USB v1.1 (upto 12 Mbps) standard.
Then, the MIDI messages appear on the computer at a virtual serial port (called "COM" port on a Windows computer) running at 125 Kbps, ie. much faster than MIDI speed at 31.25 Kbps. Our software takes the data from this serial port and allows you to route the data in a variety of ways to the software or device of your choice. Once configured using our editor you can use the USB-microDig with any software that communicates directly with devices through the virtual serial port. Our Link software has even more capabilities. And, on Windows, you can use our BlueMIDI application to map the data to/from the serial port from/to a virtual MIDI port.
The USB-microDig is compatible with most operating systems: Windows 2000/XP/Server 2003/Vista/7, MacOS 9 and MacOS X, Linux 2.4 and 2.6.
But wait, there is more ... !
The USB-microDig can also control actuators: the AUX row of the input/output connector contains 8 digital outputs dedicated to controlling actuators, enabling you to have both 8 sensor inputs as well as 8 actuator outputs. In order to use the outputs, you have to change the position of one pin in the housing of the actuator plug, and they cannot be used at the same time as the inputs unless you make a custom "splitter" plug adapter. The AUX outputs are for control only. To drive an actuator you need to install a transistor or similar, that is controlled by the AUX output, to enable/disable power supplied to the actuator.
Also note the USB-microDig's I2C capability which is one of the more common bi-directional communications protocols used in robotics for sensors and actuators - connect upto 4 I2C devices directly to it. But you can connect many more I2C devices, since they can be daisy-chained !. Finally, you don't need to connect a power supply to the USB-microDig since it's USB powered (up to 300mA for all the sensors and actuators together).
Far and beyond.
If you need to use the USB-microDig further away from the computer than the cable permits, regular/passive USB extension cables upto 6ft, longer ones that are powered/active or even longer ones that use CAT5 cables (as used for ethernet) work fine. Also, wireless USB devices or TCP/IP-based (WiFi or ethernet) USB device servers should work with the USB-microDig. Check our page with other products to use with I-CubeX for 3rd-party solutions. You can also use our ExtendCable-5 to place sensors further away.
Get it now !
It is sold as part of the USB-microSystem. Use the USB-microMIDICable to connect the USB-microDig, after having configured it in stand-alone mode, directly to your MIDI gear, and power the USB-microDig with either a USB-microGlobalAdapter, a USB-microBattery or simply a USB port on your computer.

The LED designated as "IN" blinks when data is sent by the USB-microDig, whereas the LED designated as "OUT" blinks when data is received by the USB-microDig.
Using the Advance-645, Loud, but especially the ReachClose or ReachFar with the USB-microDig may increase the noise of the sensor power supply. Hence, other sensors, especially the Reach, connected to the same USB-microDig may show more noise in their output.
