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.
