A window will appear which listens for all NCD UDP broadcasts.? Plug in your Web Relay Board and wait for the Network window to populate with the IP address of the Web Relay Board. Enter the IP Address into a Web Browser or double click on the Web Relay Board in Base Station you should be brought to the Web Page for that board. From there you can configure the interface, control relays, or read inputs. Base Station is a tool designed to teach you all the features built into your controller and provide you with example commands.? Base Station was written for Windows using Visual Studio (source code available on the download page linked above).? Base Station shows you all the commands you need for controlling relays and monitoring external sensors. ### Base Station Software Base Station Software was designed to help you learn the ProXR command set. ?Explore ProXR features using our Graphical User Interface. ?Watch data bytes flow to and from the board, so you easily understand the command execution process. ?There is no faster or easier way to learn how to automate than Base Station, as it was designed to work ?with our complete array of communication modules, including Wireless, Ethernet, USB, RS-232, and many more. ?You only need a Windows 8 or 10 Computer to Run Base Station. ?Base Station was written in Visual Studio, and we even provide the source code to help you on your way!?[Learn More about Base Station Software Here.](https://ncd.io/start) ![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-19-103525-300x205.png) ### 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. ![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-19-103838-300x145.png) ### 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. ![](https://maker.wiznet.io/uploads/2022/07/Screenshot-2022-07-19-104037-300x207.png) ### 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. --- Source: https://maker.wiznet.io/siva_ranjeet/resellers/Web-Relay-Controller-with-20-or-30-Amp-Relays-amp-Web-Page-Interface/
