Bluetooth Relay Board from NCD
An NCD Bluetooth Relay board makes it easy for computers of all types to control relays and monitor analog inputs. Bluetooth Relay boards allow you turn relays on or off, flash relays continuously, control relays for a duration of time, and control relays in groups using a cross-platform compatible Bluetooth interface. NCD ProXR Lite series controllers are a widely adopted standard used by industry for many years. Equipped with your choice of 1, 2, 4, or 8 on-board relays, the ProXR Lite series Bluetooth Relay boards suit the needs of most of our customers. Integrated Analog to Digital Converters may be used to manually control the relays, or they may be used to read external sensors. Equipped with 8 or 10-Bit resolution, the ADC built into NCD Bluetooth Relay boards add tremendous flexibility for various application requirements.
We have implemented the Bluetooth Serial Port Profile (SPP) on all NCD Bluetooth devices. Your NCD Bluetooth Relay Board will mount as Virtual COM Port once connected to your computer, allowing a wireless link using simple serial communications. The SPP is compatible with all Windows and Linux Desktop PCs as well as Most Android devices that support the SPP profile. We have reason to believe SPP is compatible with Macintosh computers, but this has not been tested. SPP is not supported by iOS devices.Getting Started with an NCD Bluetooth Relay Board
Start by downloading Base Station at https://ncd.io/start. Plug in your Bluetooth Relay Board and Pair the device with your Bluetooth equipped PC. Run Base Station. Base Station is a tool designed to teach you all the features built into your controller and provide you with example commands. Our Bluetooth Relay Board mounts as a virtual COM port on your PC. Base Station will display a list of all available COM ports on your computer as soon as the program starts. Choose the Bluetooth COM port to establish communications with your Bluetooth relay board.

AD8 8-Channel 8/10-Bit Analog to Digital Converters
This controller is equipped with 8-Channels of 8/10-Bit Analog to Digital Converters, capable of reading analog voltages from 0 to 5 Volts DC. The ADCs on this controller allow monitoring of external sensors or contact closure input detection. Connect external temperature sensors, light sensors, current sensors, buttons, switches, or anything else that generates a 0-5VDC analog or contact closure output. With 8-bit resolution, analog inputs will convert 0-5 Volt signals into a value from 0 to 255. With 10-bit resolution, values of 0 to 1023 may be measured. Input resolution is software selected. Simply ask the controller for the analog value of each input, and the controller instantly responds.
Relay Activator and Analog Inputs
The Relay Activator control panel allows analog inputs to directly control relays. Simply connect the analog inputs to buttons or switches and trigger basic relay on or off functions to take manual control of the on-board relays. The Relay Activator control panel allows you to define 8 functions for each of the 8 inputs. Functions include turning relays on or off, toggling the state of relays, momentarily flash a relay, momentarily toggle the flashing function of a relay, turn all relays on, turn all relays off, and push notification events. When push notification events are configured, the controller generates a packet of data every time the inputs change state.

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.

AD8 Analog Input Usage Notice
Analog Inputs should not have a voltage present when powered down. Use a 220 Ohm current limiting resistor on each input to prevent damage to the controller if voltage will be present on the analog input when this controller is powered down. Do not exceed 0 to 5VDC on any analog input or the on-board CPU will be damaged. Most analog inputs include a 10K Pull Up/Down resistor to help keep the inputs quiet when not in use. This 10K resistor may slightly bias the readings of some sensors.
