Ethernet Interface with A/D Conversion

Uses Lantronic XPort firmware.
Providing a TCP/IP Network Communications Solution to NCD Devices.
Faster Communications & Base Station Discovery

Lantronix XPort

This board is equipped with a Lantronix XPort Module.  The Lantronix communications module adds Ethernet communications to the board.  The module will connect to a your router with a standard CAT-5 cable.  The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type transformer at checkout.

Sending Commands

Base Station Software is available at no charge to get you up and running fast (more on Base Station below).  Once powered up, the controller waits for a ProXR command.  A command consists of a few bytes of data in numerical format (ProXR Enhanced Command Set) usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.  If a command was sent to read the status of the relay the status is sent back.

Induction Suppression

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer.  Controlling a inductive load using this relay controller requires the use of induction suppression capacitors.  The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay.  Without this capacitor, the lifespan of the relay will be greatly reduced.  Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly.  In the case of Ethernet devices, customers may experience loss of communications until the device is reconnected.  Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.

Wi-Fi Adapter Available

Make this ethernet controller Wi-Fi compatible by simply connecting the Netgear WNCE2001 Universal Wireless Internet Adapter. The WNCE2001 will connect any of these Web Relay devices to an existing 802.11 wireless network. Installation couldn't be easier with Netgear's CD-less, wireless installation. The Netgear WNCE2001 can be purchased on your own or select the Wi-Fi option at checkout to add to your order.

Easy Software Development

Most of our customers write their own program for controlling these devices and use almost any language to do this.  This boards supports the Serial Port Profile, meaning they will mount to the computer as a virtual com port making it very easy to send commands to the device.  This board will support almost any programming language you are comfortable with.

Plug-In for Visual Studio

The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and fully customizable to your needs.  Over 40 samples included with this free download!  Component Library.

Base Station Software

Base Station will assist you in learning how this device functions and is the ultimate reference tool for setting up, testing and controlling this device.  Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software.  Base Station works by communicating with your controller to identify the model and provides the appropriate graphical user interface for setting up and testing the identified device.  To help you get started and learn this controller Quick Start Guides are available for just about every feature.  As you discover a feature in Base Station a link is provided where you can easily download the Quick Start Guide.

ProXR Lite Relay

We've looked at the interface and the programming now let's take a look at the board design itself.  The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design.  Fully tested before they leave the production facility each ProXR Lite controller is ready to stand up to rigorous demands from heat, cold or vibration.  The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions.  Take it from us, these controllers will hold up!

Break-A-Way Tabs for a Smaller Design

The ProXR Lite relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure.  Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.

Not Expandable

Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.

Read Analog Sensors

We did NOT skip the Analog Input portion of the ProXR Lite.  All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control.  Read and control from 8 sensors per board from 0 to 5 volts.  Look for more on this below.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable.  The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market.  The list of commands and parameters this board is capable of is extensive.  ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before!  For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

RoHS Compliant

This board is led free and RoHS Compliant.  If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.

30-Day Warranty/Money Back Guarantee

ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 30 days!  Not to mention a 30-day money back guarantee!  If for any reason you are not happy with a relay purchased from National Control Devices, simply return it within 30 days and we will give you your money back!  Controllers that are damaged by our customers will not of course be warranted under any circumstances. 

Thousands or Relay Cycles

ProXR Lite series controllers are designed for long life, you should expect to get years of service from your controller and literally thousands of cycles from the relay(s) onboard.  With a 30-day warranty and a money back guarantee you have nothing to loose!  Place your order now, while everything is in front of you.

Shipping

The boards sold are brand new units shipped from our office conveniently located in Missouri.  These boards are completely tested before they are released for shipping  With so many boards on our site it is impossible to stock boards, please allow two to three days production time for your order to ship.

A/D Conversion on the R85PL_ZETH-ME

Analog to Digital conversion is available on the R85PL_ZETH-ME controller.  Analog to Digital Conversion allows you to read voltage levels from 0-5 volts using 8-bit or 10-bit resolution.  A/D Inputs are useful for reading, temperature sensors light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of.  Built-In Pull-Up/Down Resistors keep the inputs quiet.  Eight Different A/D Sample programs are available in the NCD Component Library.  These samples are available as a free download and are compatible with Visual Studio.   We've got sensors!  Visit our Sensor Page for sensors that have been tested and work with the R85PL_ZETH-ME controller.
