ETH32 General purpose I/O Total of 34 I/O lines 8 Analog input channels Event monitoring Ethernet connectivity TCP/IP communications Software libraries for Windows and Linux

General Description

The ETH32 includes a variety of useful features for data acquisition, monitoring, and control purposes. In addition to digital I/O, certain I/O lines can function as analog inputs, digital counters, and pulse width modulation (PWM) outputs. One of the powerful and useful features of the ETH32 is its event monitoring capabilities. In a nutshell, event monitoring allows the ETH32 to monitor different input signals and send a notification to your application when that signal has changed or met your criteria. Since the monitoring is constantly performed directly by the ETH32, it provides a much better alternative to polling over the ethernet connection. It provides faster response, is very efficient with network traffic and CPU resources, and is typically much easier to implement in your application. Event monitoring capabilities are included for digital I/O ports, analog channels, and digital counters.

Hardware Features

• A total of 34 I/O lines
• All I/O lines can function as digital I/O, each being individually configurable as an input or an output
• Eight of the I/O lines support analog readings with a 10-bit ADC
• TCP/IP communication over 10BaseT Ethernet allows flexibility in placement and usage
• Event monitoring allows the device to monitor digital I/O lines, analog signal thresholds, and counter values and notify a PC when criteria has been met. This allows very fast monitoring of signals without introducing any network traffic until something significant happens
• 32 of the digital I/O lines support event monitoring
• Analog signals can also be monitored by the device, with events fired whenever the signal falls below or rises above user-defined thresholds
• Supports five simultaneous TCP/IP connections, allowing multiple computers to monitor and control the device
• Two user-controllable status LEDs directly on the ETH32
• Two of the I/O lines can be configured as digital counters, one 16-bit and one 8-bit. Hardware Events are also supported on the counters. A counter can be configured so that an event fires when the counter reaches a specified value.
• Two of the I/O lines can be configured as PWM outputs.

Software Features

• Comes with software libraries for both Windows and Linux, making it very simple to use the device.
• Includes support for Microsoft .NET languages, Visual Basic, C, and C++. A user-contributed REALbasic library is also available.
• The protocol used over the TCP/IP socket is documented for those who want to do the network programming themselves or are using an unsupported platform.
• Comes with a configuration application that allows the device's IP address, subnet mask, and gateway to be configured over the network connection. This uses UDP broadcast packets to detect all ETH32 devices on the local subnet and configure the selected device. By using UDP broadcast packets, a device can be configured even if its current IP address does not match the local subnet.
