Wi-Fi, Bluetooth, USB or Web Page Control
Integrated web server allows control of select NCD relay controllers using a built-in non-secure web page.
WiFi Relay Control
The NexGen WiFi is NCD's second generation WiFi communications module that modernizes connectivity by combining WiFi, Bluetooth, USB, and MQTT Communications into a single module. The NexGen WiFi module includes firmware that focuses on the most needed features while retaining the flexibility to adapt to just about any application. Using the integrated web page in Soft AP mode, users have the ability to configure the NexGen WiFi module by enabling and disabling features as needed.Three Interface Options, ONE Module!
WiFi Communications
The NexGen WiFi module supports TCP communications, essentially converting TCP data to serial data for device control. Configure network setting such as DHCP or a Static IP address. Configure the network Port number and serial baud rates for connectivity to the NCD device using the integrated web page while in Soft AP mode. The Soft AP mode is compatible with web browsers on mobile devices such as Android or IOs devices, as well as laptops and desktop computers with integrated WiFi communications. Once configuration data is complete, exit the Soft AP mode and use the optional integrated web page to control basic relay control functions via the integrated web page (non-secure) or send data to the WiFi module using some of the optional protocols supported below.Bluetooth Communications
The NexGen WiFi module also supports Bluetooth connectivity via the Bluetooth Classic protocol. By implementing the Bluetooth Serial Port Profile, NCD products will appear to your computer as a standard COM port, making it easy to communicate wireless data via Bluetooth between the PC and the device. Users have the ability to set the Bluetooth discovery name and PIN number via the integrated Web Page using Soft AP mode.USB Communications
We also built the NexGen WiFi module to include a USB port, which may be used for direct USB communications to the device. Simply configure the USB Virtual COM Port parameters using the Soft AP mode and the integrated web page. The NexGen WiFi module will mount as a COM port on your computer, allowing access to the device through serial communications.WiFi Communication Protocols
MQTT
The NexGen module supports very basic MQTT usage. It can be configured to connect to an MQTT broker using no auth or basic auth (username/password). Testing of this functionality was done using beebotte.com. The NexGen WiFi module implements one subscribe topic and one publish topic. It listens for control commands over the subscribe topic and sends command responses to the publish topic, which may be user defined using the integrated web page in Soft AP mode.HTTP
Using WiFi communications, it's also possible to send commands to NCD devices using the HTTP API. For example, to activate a relay on a NCD device, Simply send the HTTP command to the IP address 192.168.1.10 in any web browser using the following command structure: 192.168.1.10/sendCommand?data:[254,108,1]Web Socket
Use a Web Socket to send commands to a NCD device. Users can establish a web socket to the board via ws://{controller IP}/ws. This web socket expects command bytes to be sent in the form of a JSON array, for example [254,108,1] (activate the first relay on a NCD relay board). Note this array should be sent in TEXT/String format as shown with quotes. Any data received from the host board will be sent to the web socket in the same format (JSON Array).Discovery and Diagnostics
UDP Broadcast
The NexGen module broadcasts a UDP packet on ports 55555 and 13000 for network discovery purposes. This allows discovery of the the NexGen WiFi module in Base Station and may be used for network discovery in your own software applications.RGB Status LED
The integrated RGB LED displays communications and status information. Diagnose connectivity status or communication problems with different flashing color patterns to indicate module bootup, wifi connectivity, and configuration modes.Taralist NTP Time Sync
This option enables Network Time Protocol time syncing of the Taralist Real Time clock. When enabled, once per day the NexGen module will sync its time with time.google.com, then it will update the on board Taralist Real Time clock. Note that this feature is only valid on Taralist series relay controllers and will only work if WiFi is enabled and internet connectivity is present on the connected WiFi Network.Compatibility
For use with 2.4GHz WiFi Networks ONLY. This module does NOT support 5GHz WiFi.PLEASE CONSULT WITH NCD STAFF PRIOR TO RETROFITTING OLDER DEVICES WITH THIS MODULE!
ONLY NEWLY PURCHASED CONTROLLERS ARE COMPATIBLE WITH THIS MODULE!
In general, this WiFi module works with Fusion series controllers regardless of version. However, this module is NOT COMPATIBLE with older relay boards that you may want to retrofit with WiFi communications. This module requires more power than older devices are capable of supplying. This device is fully compatible with any G2 board revision, such as boards marked with Rev G2A, G2B, G2C, etc. G2 boards are typically black in color with the exception of Taralist controllers, which are also black in color but NOT equipped with G2 revision markings (and not compatible). If G2 is not marked on the board revision and you are not using a Fusion series controller, this module is NOT compatible. Newly purchased controllers will include a power supply upgrade, allowing compatibility. A service charge to upgrade the power supply on older devices may apply when retrofitting this module.
WiFi Bluetooth USB 3 in 1 Module with MQTT Support
Control NCD devices using standard WiFi TCP/IP communications or use the integrated Bluetooth for simple wireless computer to device interface using a wireless virtual COM port. Use the USB port for control over a virtual COM port for easy connectivity. Integrated web server allows control of select NCD relay controllers using a built-in non-secure web page. This is a low-cost solution that lets you try different solutions with easy setup using a integrated Web Page User Interface for all Configuration settings. Connect to a MQTT Server over WiFi for remote operation over the internet.ProXR Expandable Board
This Board includes the XR Expansion Port for adding additional relays to the board. The XR Expansion Boards can be added to control up to 256 relays on this board!
ProXR Relay
We've looked at the interface now let's take a look at the board design and programming. The ProXR series controllers are manufactured by hand for a highly accurate and reliable design. Equipped with the XR Expansion Port additional relays can be easily added. Fully tested before they leave the production facility each ProXR controller is ready to stand up to rigorous demands from heat, cold or vibration.

UXP Expansion
UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. You will find the UXP port on models with UXP in the part number.- Summary of UXP Modules
- Compatible with UXP Series Controllers ONLY
- Not a stand-alone controller - MUST be used with a UXP Series Controller
- Add Contact Closure Inputs
- up to 256 Inputs - Add Analog to Digital Inputs
- up to 48 Inputs - AddDigital Potentiometer Outputs
- up to 256 Outputs
UXP Expansion Modules
UXP Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. A master device is an NCD controller with a UXP expansion port and a microprocessor of some kind. Most master UXP devices have on-board relays. If you need to add A/D, Contact Closure Inputs or Digital Potentiometers just plug in the appropriate expansion module. You cannot daisy chain different types of modules to the same controller however. In other words if you plug in a potentiometer you will not be able to plug a contact closure or A/D module also. For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number. All UXP Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for.XR Expansion Port
Most UXP controllers (Master Devices) have an XR expansion port and therefore can accommodate XR Expansion Boards. Typically the XR Expansion port is used to add relays to the main controller (Master Device). Like the UXP Expansion boards the XR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a "master" device. When you run out of relays, just plug in an XR expansion board that is equipped with the kind of relays you need. You can add up to 256 relays including the relays that are on the main controller (Master Device). All XR Expansion modules are compatible with each other so if you want to add different types of relays you can. For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.Using XR and UXP Together
If you select a board that is equipped with both XR and UXP port you can use both ports simultaneously. This allows you to add and control more relays through the XR port plus add A/D, Contact Closures or Potentiometers to the same board through the UXP port. This can all be controlled through the same virtual COM port on your computer. These Expansion Boards can be purchase with the controller or purchased at a later time when you have a need to expand. To use both ports together you will need to select a controller that has UXP and PROXR in the part number to have bothports available on the controller (Master Device).ProXR Enhanced Firmware Installed
This board has ProXR Firmware installed that responds to the full ProXR Command Set. The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market. The list of commands and parameters this board is capable of is extensive. ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before! For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.Essential Power Requirements
Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Relay Timer

Time Schedule Control
Relay Timer Software allows you control each relay independently from a time schedule you create! The software can be installed on a server or PC and uses the computers time for an accurate relay control.Control relay in recurrent time sequence
Thanks to protocol of ProXR & ProXR Lite boards it is possible to update 8 relays at one time. If speed is a requirement it only take about 30 ms to update 8 relays. In multiple relay applications Relay Timer calculates all relays’ status together, even though each of them work separately.Take Manual Control
You can take manual control of any relay at any time to interrupt the schedule and control a relay. Automatically switch back to Auto Mode and resume the schedule manually or set a fixed time to return to the schedule.Quick Timer

Time Sequence Control
Quicktimer Software supports turning on/off each relay automatically during the predetermined duration. First set the duration that you want the sequence to be active. Time periods can then be set where the relay is energized within the set duration.Control Relays by Time Duration
Quick Timer is a software program specifically developed for the relay boards on our site. The software will allow you to control the duration the relays will be energized. This software is not designed to control relay at a specific time of day but rather a time duration. The time sequence is manually started and can run through a set sequence and stop of be set to loop until manually stopped.Control Within a Predetermined Duration
Quick Timer Software supports controlling each relay automatically during the predetermined duration. A duration can be set first then each relay on the board can then be controlled with their own time sequence within the set time duration.Component Library
