About 802.15.4 Wireless

802.15.4 Wireless Relay802.15.4 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

802.15.4 wireless ModuleThis 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 Module Data Sheet.

Line-Of-Site Operation

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 Options

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.  Extension cables can be purchased.  The connector type is RP-SMA (Reverse Polarity SMA).  You will need a cable with RP-SMA Male and RP-SMA Female connectors.  We do not stock these cables or recommend any specific cable.  Antenna extension cables will reduce signal strength and are generally not recommended over 20 feet, though individual results will vary.  Please note that the internal antenna modules (shown above) have antennas that are about an inch long and integrated into the module therefore the external antenna cannot be used on an internal antenna module or added after purchase.  Prices shown are with the 300' internal antenna option, external antenna options are available at checkout.  802.15.4 Module Option

802.15.4 Wireless Modem

802.15.4 ModemPlug 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

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 (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.  If a command was sent to read the status of the relay the status is sent back.

Induction Suppression

Induction CapacitorPerhaps 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.

Makes Wireless Control as Easy as Talking to a Serial Port on your Computer!

Easy Software Development

Most of our customers write their own program for controlling these devices. You can use almost any language to do this.  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.  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

ProXR Relay

We have looked at the interface and the programming now let's take a look at the board design itself.  This controller allows you to send simple commands to activate relays, read the status of relays, activate up to 16 relay timers, and control up to 256 total relays using the XR expansion port.  All relays are electronically latched, simply send a command to turn the relay on, send a different command to turn the relay off..  Fully tested before they leave the production facility each ProXR 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 stack up!

Add Relays as Your Needs Grow
The ProXR series controllers are expandable up to 256 total relays.  The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay.  Expansion boards can be added until you reach 256 total relays.  the Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.

Read Analog Sensors
This ProXR controller offers 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!

ProXR Firmware Installed
This board responds to the full ProXR Firmware.  The ProXR Firmware is the industry leading firmware with the more commands and functionality than any other board on the market. click here to see the ProXR command set.

  • Relay status light bar
  • XR Expansion Port
  • Screw terminal or direct relay connections make connecting to the board easy

    ProXR Features
  • Works with the full ProXR Command Set

Analog to Digital Conversion

Analog Inputs are very special in that they are sensitive to voltage changes.  Analog to Digital (A/D) conversion is the process of converting a voltage in the range of 0 to 5VDC into a number that can be processed by custom software that you develop.  The ProXR Command Set will allow you to send a command to the board and read voltage levels from 0-5 volts using 8-bit resolution.  8-Bit resolution will read the voltage input (from 0 to 5VDC) and then is interpreted as a value from 0 to 255.  Zero being a contact closure input.

    For Example
  • A voltage input of 0 Volts is interpreted as a value of 0
  • A voltage input of 2.5 Volts is interpreted as a value of 127
  • A voltage input of 5 Volts is interpreted as a value of 255

So if you divide 5 Volts by 255 possible steps (0-255 for 8-Bit resolution), the board is sensitive to voltage changes as small as 0.019 Volts.  This controller has eight A/D inputs, each input is capable of reading a separate voltage from 0 to 5 VDC, provided all voltages can share a common ground.  This is particularly useful for reading temperature sensors (one temperature sensor is built into select boards mostly 4 & 8 channel, shared with analog input number 8).  A/D Inputs are also useful for reading light level sensors, thermocouples, switch closures, or just about any other kind of sensor you can think of.

A/D Sample Programs Available

Eight Different A/D Sample programs are available in the Component Library.  These samples are available as a free download and are compatible with Visual Studio.
