Would you like to use your PC in a data acquisition or control application?  The USB Digital I/O Commander ("Digio") allows you to set digital outputs and read digital inputs.  In addition, it allows you to specify an action to occur when a specific trigger input or set of inputs change state.  For instance, you can configure the software to send a pre-determined e-mail message to a recipient when input bits 0 to 3 equal the value "14".  Or, configure to play a wav sound when bit 5 is "high".  You can do this and much more.  With 7 different notification types, the possibilities are limit-less.

New in version 5.11j - X10 Automation !!!   We've added an 8th notification type - X10 Automation.  Now you can perform powerful automation, control, and monitoring functions over your building's existing A/C wiring using X10 signals.  Activate appliances, lights, fans, and other devices - all under Digio control.  Compatible with X10 modules including lamp controllers, motion sensors, wall switches, plug-in modules, RF receivers, etc.  You can also specify X10 trigger events.  These events behave like other Digio triggers and generate one or more notification(s) when the specified X10 signal is received.  (Requires USB PowerLinc 1132U computer interface, available at SmartHome, Inc.).  There are a number of possible applications that can make use of X10 technology.  Here are just a few:

• Automation 
• Process control 
• Security 
• Research 
• Robotics 
• Motion Detection 
• Industrial Control 

• Set/read up to 16 digital I/O signals per USB module 
• Configure any combination of inputs and outputs
• Read, write, or test SPI slave device(s)  (U4x1 only)
• Write SPI data from a Tx file and capture data to a Rx file
• Configure input(s) as single-bit or multiple-bit event triggers
• Virtual LED displays with configurable color definitions
• Use time-triggers to generate notification(s) at specific time(s) of the day or week
• Use signal-triggers to generate notification(s) when an input or set of inputs change state
• 8 different notifications including email, sound, pop-up msg, set output, write SPI slave (U4x1 only), run application, system action, and X10 command
• Attach events and perform test preview 
• Configure any combination of inputs and outputs 
• Expandable up to 160 I/O signals by adding more modules 
• Configure notification delays to limit the number of notifications over a period of time 
• Compatible with multiple email client programs including Outlook, Eudora, & Netscape 
• Configurable device polling rate
• Control & monitor devices using X10 powerline signals

The USB Digital I/O Commander gives you full control of digital I/O for any application including robotics, industrial control, or hobby I/O.  The heart of the product is the USB I/O interface.  This module provides the  interface between your I/O and the PC computer.  Taking advantage of USB technology, the system is easily expanded to suit your needs.  A single USB module provides 16 I/O signals, configurable in any combination of inputs and outputs.  If you need more signals, simply add additional modules. 

Digio software is available for the USBmicro U4x1 and ActiveWire USB interface.

Serial Peripheral Interface (SPI) is a protocol allowing a master device to communicate with many slaves.  Now, USB Digio 4.0 gives you access to these devices with a few clicks of the mouse.  No microcontroller, firmware, or programming knowledge required. Great for rapid prototyping and proof-of-concept. (Requires USBmicro U4x1 USB interface).

Do you need a networked solution for accessing your digital I/O?  Digio for Local Area Networks (LAN) offers the same functionality as the single-user product with the same U4x1 compatibility.  But Digio for LAN goes a step beyond, allowing networked computers to monitor U4x1signals and events.  Ideal for applications where remote monitoring is needed including alarms, data acquisition, etc.  Uses a peer-to-peer configuration to allow device information and events to be shared across a network.  This powerful application allows you to monitor your system from remote locations.  Even receive ASCII messages when event triggers occur.  (Requires network interface card/adapter and one or more USBmicro U4x1 USB interface(s).)

Easily connect and disconnect to your target system from remote location(s)

Uses UsbMicro U4x1 hardware interface

Receive system status for up to 10 USB devices in the target system

Supports multiple remote users

Receive text event messages from the target system

Blinking message alert indicator
