Wi-Fi Contact Closure Monitoring

With this Scan Series Controller you can monitor Contact Closure Inputs using a computer.  With minimal programming, data collection and control from a single controller allows any computer to talk this device from anywhere on a Wi-Fi network.  The SCAN Series command set allows you to read anywhere from 1 to 32 banks of 8 inputs in a single query.  A single bank contains 8 inputs.  Reading 32 banks will report the status of 256 inputs.  It doesn't stop there, because we are focused on relay control you can add relays to the board (up to 256) and control them using the data collected from the inputs.  Remember these are contact closure inputs ONLY no voltage can be applied to these inputs.  As many of our customers already know, working with Wi-Fi devices can be challenging because they must be associated to a wireless network, and must be configured with security protocols. This embedded WiFi Device supports all of the most popular security protocols for wireless security.

Easy Software Development

This device supports TCP/IP Communications over a Local Area Network or, if your network is configured properly, Internet Based Communications.  Simply attach the device to your wireless network and access it through a socket connection.

Configuring the WiFi Module

You must have a WiFi Configuration Kit to Configure the particulars of the Wireless Network the Module will connect to. We have provided Base Station Software that makes configuring the device simple.

On the software side you'll need to install the FTDI Drivers, the .NET Framework v4, and download the NCD Base Station Software.

Just put the WiFi Module into the Configuration Kit, attach the USB port of the Kit to your Computer and open the Base Station Software. From there simply select the COM Port, select Connect, and then select Enter Command Mode. After that simply fill in the information for your wireless network and application and then select the "Please Fill All Fields and Click This Button to Setup" button and they module will run through a series of commands and you're ready to control your board.  For more information on Wi-Fi configuration see Configuring the Wi-Fi Module.

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.  When a command was sent to read the status of the contact closure the status is sent back.

Easy Software Development

Most of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.  These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.

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 Contact Closure

We've looked at the interface and the programming now let's take a look at the board design itself.  The ProXR series ZSCAN controllers are manufactured by hand for a highly accurate and reliable design.  Equipped with the XR Expansion Port relays can be easily added.  Fully tested before they leave the production facility each ZSCAN 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!

XR Expansion Port

The XR Expansion Port is available for adding relays to the board.  Relay expansion boards can be added up to a total of 256 relays.  The Expansion Boards get their logic from the main board and will require 12 VDC power.

UXP Expansion Port

While the XR Expansion port adds relays to the board the UXP Expansion adds addition contact closure inputs to the board.  The ZSCAN series controllers are expandable up to 256 total inputs.  The controller is fitted with an UXP Expansion Port where you can add contact closure expansion boards to this relay.  Expansion boards can be added until you reach 256 total inputs.  The Expansion Boards get their logic from the main board and will require 12 VDC power.

ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set.  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 enhanced 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.

5-Year Warranty/Money Back Guarantee

ProXR series controllers are guaranteed against manufacturing and functionality defects for a full 5 years!  Not to mention a 30-day money back guarantee!  If for any reason you are not happy with a relay purchased from Relay Pros, 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. 

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.
