About 802.15.4 Wireless
802.15.4 is not one of the most widely known wireless technologies but it is easy to setup and use, and vey reliable. You will need a 802.15.4 modem that plugs into your USB port of your computer to talk any number of 802.15.4 relays with a standard range of 300' and up to 1 mile. You can choose the distance of the module installed at checkout.!
802.15.4 Wireless Modules
This board is equipped with a 802.15.4 Module. The 802.15.4 communications module adds wireless communications to the board. The 802.15.4 module is powered from the board. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply
at checkout. Click the following link for a spec sheet on the XBeeŽ Multipoint RF Modules
As with any wireless technologies, for optimal performance it needs to be line-of-sight. In other words the antennas of the board and modem must "see" each other to get the optimal range or even be able to communicate at all. Select the External Antenna option to provide better range especially when controller will be mounted in an enclosure or behind a wall or obstruction.
External Antenna Option
The External Antenna option is available with the 300' and 1-mile range modules and has a short pig tail that connects to a button on the 802.15.4 external module. Please note that the internal antenna modules (shown above) have antennas that are about an inch long and integrated into the module. The external antenna cannot be used on an internal antenna module or added after purchase. Prices shown are with the 300' internal antenna option.
802.15.4 Wireless Modem
Plug the XBP24-AUI-EXT_ZIGMO modem into the USB Port of your computer. The modem will mount as a COM port on your PC. Open the COM port and start sending data to the modem. The modem will forward your data to all Wireless 802.15.4 compliant devices within range (it is also possible to speak to a specific device when other controllers are in range). Mounting slots on the modem make it easy to attach to a wall to allow for line-of-site operation. The modem is also available at checkout. 802.15.4 Modem
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 (see full 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.
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
SPDT Relay Controller
This device has SPDT relays installed. SPDT Single Pole Double Throw Relays have three connections - Common, Normally Open, and Normally Closed. When the relay is off, the common is connected to the normally closed connection of the relay. When the relay coil is energized, the Common swings over to the Normally Open Connection of the Relay. You can wire the device you are switching to either the Normally Open or the Normally Closed position. For more information on selecting the correct relay amperage for your application see Choosing a Proper Amperage
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.
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!
