ProXR Quick Start Guide
Online Manual for ProXR and ProXR Lite Series Controllers
Good to Know!
NCD ProXR Series Controllers have been in production for many years and have amassed a large user base since their initial release in the early 2000s. Due to the large client base, we have no plans to discontinue this line of products. In many cases, we are upgrading these devices to make them compatible with automated assembly processes along with improved driver and power electronics capable of supporting many communication technology changes well into the future. Rest assured, ProXR will continue to be a stable part of our product line for many years to come. ProXR series controllers manufactured with a Black circuit board have been migrated to automated assembly and are considered to be the final iteration of this product. These devices can be manufactured in high volumes in a much shorter period of time.
LabVIEW Relay Control
NCD supports integration of NCD relay controllers using LabVIEW. We have included samples and drivers for basic and advanced operation which cover most functions including Relay Timers. We have posted several tutorials on this topic here.
ProXR Lite Communication Options
We take communications seriously, as we believe in modular communications and firmware that properly supports scalability into future interface technologies. ProXR controllers support API communications, which effectively wrap every command with a header, payload, and checksum to ensure reliability. NCD API commands increase processing speed because no serial timeout is required prior to command processing. NCD API commands increase reliability, as only a proper checksum will authenticate a command and allow it to process. When we first implemented API, internet communications via a TCP/IP socket could be realized because the timing problems of internet communications were eliminated. While API is optional, it is strongly advised. Our Base Station software uses API communications, so it’s possible to control a ProXR controller over the internet after configuring port forwarding on your router.
ProXR series controllers are the world’s most adaptable controllers, capable of communicating with a wide variety of communication options. Pick any of your favorite communication technologies: Bluetooth, USB, WiFi, Ethernet, Key Fob, RS-485 or RS-232. ProXR easily adapts to the communication technologies you need most. We are committed to modular communications, so your ProXR series controllers can easily be retrofitted for other applications as your needs change. ProXR controllers are never obsolete, as we are actively releasing new communication technologies that greatly enhance the connectivity of our ProXR series controllers.

Long Range Wireless Industrial Mesh
Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz. Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in many of our products, as this is the best industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away. Please note that data hopping only works between live devices. Data will not hop between sleeping sensors. Data will hop from sensors to gateways and modems. Data will also hop between gateways and modems. Learn more about our long range wireless module here.
