WiFi Module Setup
The Wi-Fi Communications Module must be configured in order to connect to your network using the Wi-Fi Configuration Kit. The Wi-Fi Configuration Kit consists of a small black board with 3 LEDs. The Configuration Board will be labeled ZIGMO. The module may have to be removed from the board and plugged into the ZIGMO as shown. The ZIGMO will plug into the USB port of your computer for configuration and some USB drivers may need to be installed on your computer. Base Station software is required to configure the Wi-Fi communications module and is available as a free download. This software identifies compatible Wi-Fi routers in your area and assigns the router you have chosen to the Wi-Fi communications module. Network security options may be configured using this software including passwords. You can find the NCD Base Station Software at ncd.io/start.
Introduction to Ethernet Relay Control

900HP-S3B Wireless Compatibility Notes
Notice: Compatibility Notes Does NOT Apply to the Following Products:
- NCD Enterprise Solutions
- NCD Wireless Sensors
- NCD Enterprise Modems and Gateways
Notice: Compatibility Notes Applies to NCD Industrial Products, Including Fusion, ProXR, ProXR Lite, Taralist, and Reactor Series Products.
Compatibility Notes
When using an 900HP-S3B communication module, it is essential that you use the ZIGMO_PCB to configure the module settings. Long-Range wireless sensors may be programmed over the air without removing the communications module.
A 900HP-S3B Modem or a gateway of some kind that support the 900HP-S3B communications module will also be required.
Ethernet TCP/IP Compatibility Notes
This device periodically sends UDP Packets on port 13,000, which help identify the IP address of this device on your network.
RS-232 Serial Compatibility Notes
The NCD RS-232 Serial communications module is compatible with standard RS-232 signals (+/-10VDC), which are not directly compatible with UART signals from a microprocessor. If you are working with Arduino, Microchip PIC, or other common microcontroller, a communications module is not required. Microcontrollers will directly talk to the on-board processor of all NCD controllers.
RS-485 Serial Compatibility Notes
The NCD RS-485 Serial communications module is compatible with NCD ProXR, ProXR Lite, Fusion, and Taralist series controllers. This module was designed to work with NCD devices, but may be used with devices outside the NCD family. This device acts as a transparent RS-485 to USART serial converter. Non-NCD products will require a software networking protocol to support multiple devices.
