General Description

The ETH32 is a general purpose I/O device which communicates using TCP/IP over an ethernet network. This device is ideally suited for remote data acquisition or device control; all that is needed is a connection to an ethernet network. The ETH32 supports up to five simultaneous TCP/IP connections, allowing multiple computers to communicate with the ETH32 device at one time. The ethernet connectivity and TCP/IP communication provide a great deal of flexibility, allowing the ETH32 to be located a long distance away from the PC if so desired.

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.

A number of convenient product accessories are available for the ETH32.

Device Features

• Devices with firmware v3.000 and above (now shipping) support DHCP.
• Devices with firmware v3.000 and above also now provide 256 bytes of user-accessible EEPROM memory storage (non-volatile - maintained through power loss).
• 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.
• Several product accessories are available.

Software Features

• Comes with software libraries for Windows (supports XP, Vista, Windows 7, 8, 10) and Linux, making it very simple to use the device.
• Includes support for Microsoft .NET languages (C#, VB.NET, etc), C / C++, and Visual Basic 5/6. 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, or DHCP to be enabled or disabled 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.
