Industrial IoT Wireless to RS485 Modem
Our long range wireless enterprise series sensors are an easy to use and reliable start to any data aggregation application. This video will demonstrate how they work, what they do, and how to use them.
Industrial IoT Wireless to RS485 Modem
Connect to the NCD wireless sensor ecosystem using the industry standard RS485 interface. Our new IoT Wireless RS485 modem makes it easy communicate with NCD wireless sensors over RS485 by simply opening a COM port and watching for incoming data to arrive as sensor data is broadcast. We have stripped away complexity and focused on what you need most, an easy way to get wireless data over a RS485 connection. With a 2-Mile range (line of sight), this device operates at 900MHz for deep penetration through trees, foliage, and even some buildings. With integrated Mesh networking, this device also acts as a repeater for sensor data. Designed to work with any operating system that supports RS485 communications.
This RS485 Wireless modem was designed for indoor use only. Requires a 12VDC Power Supply (optional during checkout).
3 Variations of Wireless to RS485
When ordering this device, you will be prompted to choose a product variation. There are currently 3 different variations available, based on your application requirements. Below is a summary of the command versions available but if you have any questions, please do not hesitate to consult us prior to purchase.
The standard version is ideal when working with computers, as it serves as a raw translator between Wireless and RS-485. This version is generally preferred when working with a raw data on a PC or a computing platform where software development is powerful and flexible. This version offers the greatest possible speed and versatility, but requires more software to target and parse communications data. This version is ideal for working with Node-RED, Visual Studio, Python, or other powerful languages that provide extreme flexibility. The Standard Version is ideal for installations with existing RS485 using computers as a master control for the network.
The AutoEncoder version simplifies communications with wireless devices by automatically encoding and decoding XBee API packet structures. This means software is easier to write, as you only move payload data into and out of the RS-485 protocol. You do not need to deal with checksum encoding or decoding with this version. Because this is processed using a processor and firmware, it’s a little slower than the Standard version. Specialty commands are available to target multiple wireless devices, configure the network ID, and much more. The AutoEncoder version is a great choice for PLCs where limited programming environments are available. Put simply, if working with the Digi XBee API is intimidating, this version can save you a lot of time. This version is NOT supported by our Node-Red Drivers.
The Emulator Version of the RS485 modem is ideal for customers who are already using NCD wireless sensors and wish to adapt existing RS485 messages to follow NCD standards for device communications. The Emulator version essentially takes incoming RS-485 data and attaches additional information to make existing equipment act like a modern NCD IoT sensor. The Emulator Version also accepts similarly formatted messages over wireless and sends only the payload to the RS485 network. The Emulator Version is among the easiest of the RS485 Modem versions we currently offer, and is an ideal choice for PLCs with limited resources to communicate effectively with existing RS485 networks as well as existing NCD IoT sensors.

What Frequency Do I Need?
During purchase, you will see three frequency options. Not all options are legal for use in all areas, so it’s important to make the right selection during purchase. We will build your product and accessories based on the options chosen. Here, we will explain these options in much greater detail, but please check your local laws BEFORE purchase.
900MHz for North America (U.S., Canada, and Mexico)
If you are located in North America, the 900MHz Option will provide the longest range currently supported with the best penetration through walls, buildings, industrial equipment, and trees. This option is also the best choice for long range applications. The official Line of Sight rating for this option is 2 Miles with included antennas or 28 Miles with high-gain antennas. We suggest contacting Digi.com for a high-gain antenna recommendation if required. Please check your local laws before choosing this option.
868MHz for Europe Only
If you are located in Europe, the 868MHz Option is the only legal choice available at this time. This option offers better penetration through walls, builds, trees, and industrial equipment that 2.4GHz. The official line of site rating for this option is 14.5km using 2.1dBi antennas. Please check your local laws before choosing this option.
2.4Ghz for Worldwide Use (Except Europe)
The 2.4GHz option should be chosen if 900MHz and 868MHz are not legal for use in your country. Please note this particular module is NOT LEGAL for use in Europe, as it has a higher transmission power than is legally allowed at 2.4GHz. This option is certified for use in the United States, Japan, Australia, Brazil, and South Korea. Please check your local laws before choosing this option.
If you are unsure of which sensor option to choose, please contact us. We may be able to help determine which sensors are legal for use in your area.
Node-Red: IoT Without the Code
We’ve built Node-Red libraries so that you can build your entire IoT ecosystem with no coding necessary. We are currently updating our libraries to include this device, full Node-Red Support coming soon.
900HP-S3B Industrial Wireless 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.
RS-485 Serial Communications Node
Our RS-485 Serial Communications Module makes it easy to network up to 256 NCD devices together at distances up to 4,000 feet. Each RS-485 node includes 3 screw-terminals for a 3-wire connection to the RS-485 master.
