If you’ve picked up one of our RX01 industrial sensors, you already know they’re built to handle the heavy lifting—running the core operations for everything from small factory automation lines to precision inventory tracking systems. But even the most rugged, well-engineered hardware relies on firmware updates to fix small glitches, boost performance, and unlock features you didn’t even know your RX01 could support. As the team that designs and supplies these units to manufacturers and system integrators across North America, we get a lot of questions about updating RX01 firmware, and a lot of folks tell me they’re nervous about messing it up. That’s why I put together this step-by-step guide, straight from the engineers who build every RX01 that leaves our warehouse. I’ll walk you through every part, no jargon, no confusing dead ends—just real-world advice from people who’ve worked with these sensors for years. RX01
First, let’s get one thing straight: firmware updates for the RX01 aren’t like updating your phone’s operating system. This is industrial hardware, so there are a few non-negotiables before you even connect anything. I’ve seen integrators skip these and end up with a sensor that won’t turn on, or worse, one that’s throwing off production data. Let’s start with the pre-checks, because skipping these is the number one mistake we see.
Before you do anything, confirm two key details: your RX01 model and the current firmware version it’s running. The RX01 line has two variants—RX01 Basic and RX01 Pro—and each has its own firmware file. Mixing them up will brick your sensor, plain and simple. To find the current firmware, you can pull it from your existing setup software (we provide this for free with every RX01 purchase) or check the system log on the device itself if you have local access. We also recommend checking our official update repository once a quarter—we release firmware every three to six weeks, usually on the third Wednesday of the month, so you don’t have to scramble for info.
Next, verify power supply and connectivity. The RX01 needs a steady 24V DC power supply during the entire update process—any dip or drop out halfway through will corrupt the firmware. We’ve tested this: a 2-volt dip for even three seconds is enough to leave the sensor unresponsive. For connectivity, you’ll need either a local Ethernet cable (our preferred method, it’s the most reliable) or a serial USB adapter for older systems that don’t have Ethernet ports. Skip Wi-Fi for updates unless you have no other option—industrial Wi-Fi can be spotty in factories, and a weak signal mid-update is a disaster. Finally, back up your existing configuration file. This is another step people skip, and when they do, they end up re-calibrating every setting, from sensor sensitivity to output thresholds. Our software has a one-click backup button—use it. It takes 10 seconds and saves hours of work.
Now, let’s get to the actual update process. I’ll assume you’re using the local Ethernet method, which works for 90% of our customers. First, download the correct firmware file for your RX01 model. Head to our secure update portal (we’ll never ask for sensitive info to access this, just your sensor’s serial number, which is on the bottom of the unit) and select the latest version. Make sure the file size matches what we list—RX01 Basic firmware is around 12MB, RX01 Pro is 18MB. If it’s way off, you’ve downloaded the wrong file, so stop and try again.
Once the file is downloaded, open our RX01 Setup Software (we have versions for Windows, Mac, and Linux, so no matter what OS you run, you’re covered). Plug your Ethernet cable into the RX01’s port and your computer, then power on the sensor if it’s not already on. The software will automatically detect the RX01—if it doesn’t, double-check the Ethernet connection, your computer’s local network settings, and that the sensor is getting proper power. It should pop up in the “Connected Devices” pane within 30 seconds. If not, give it a minute, and if that doesn’t work, reach out to our support team—we can walk you through troubleshooting over the phone.
From there, go to the “Firmware Update” tab in the software. You’ll see a button that says “Select Firmware File”—click that and navigate to the file you downloaded earlier. The software will verify the file immediately; if it’s not the correct version, it’ll flag that and ask you to pick another. Once verified, click “Start Update.” Here’s the critical part: do NOT interrupt the process. No closing the software, no unplugging the sensor, no moving the Ethernet cable. The update takes 2 to 5 minutes, depending on your connection speed. You’ll see a progress bar in the software—once it hits 100%, the sensor will restart automatically. That’s normal. Don’t panic when the lights flash— that’s part of the process.
Once the sensor restarts, wait an additional 2 minutes for it to boot back up fully. Then, check the firmware version again to confirm it updated correctly. Go back to the “About” tab in the software and cross-reference it with the version you downloaded. If it matches, congratulations—your update worked. Now, go ahead and restore your configuration file (the one we had you back up earlier) and test a quick sample reading to make sure everything is working as it should.
But wait—what if something goes wrong? You’re not alone. We get 2 or 3 calls a week from customers who run into issues, and most of them fix it easily. If the update fails halfway through, first double-check that power didn’t drop. If power was steady, try reloading the firmware file and running the update again. If the sensor won’t turn on after the update, don’t throw it out or return it yet—use our recovery mode. To trigger recovery mode, hold the small reset button on the side of the RX01 (it’s a tiny pinhole, so use a paperclip or similar tool) while powering the sensor on. Hold it for 10 seconds, then release. The sensor will boot into a special recovery mode, and the setup software will prompt you to reinstall the firmware. We’ve only had one sensor out of 10,000 that couldn’t be recovered this way, so this is almost always a fix.
Now, let’s talk about best practices to keep in mind. First, never update firmware during peak production hours. I’ve seen integrators do this to save time, and when the update takes longer than expected, it brings down an entire assembly line. Schedule updates for overnight or weekend when the line is idle. Second, test the new firmware version on a spare RX01 first if you have one. If you have a backup sensor, run the update on that first, verify it works, then update the main unit. Third, sign up for our firmware alert service. All you need to do is provide your email when you purchase your RX01, and we’ll send you a heads-up when updates are available, along with a note on what the update does—fixing a rare calibration bug, adding support for a new sensor accessory, improving data transmission speed. No more checking the portal every month.
A quick note for customers using older RX01 units that don’t have Ethernet ports: for those, we provide a USB-to-serial adapter cable that plugs into your computer’s USB port and the sensor’s serial port. The process is almost identical—you just select the serial connection in the setup software instead of Ethernet, and the update works the same way. The only exception is that the update takes a little longer, around 5 to 7 minutes, because serial connections are slower than Ethernet.
At the end of the day, the RX01 is built for reliability, but firmware updates are a key part of keeping it running at peak performance. We design every update with your operations in mind—we don’t push out unfinished software, and every update is tested on hundreds of prototype units before we roll it out to customers. If you have any questions, run into snags, or want to learn more about the RX01 line, our team is here to help. Whether you’re looking for a spare sensor, need support with an update, or want to bulk order units for a new project, we can walk through your needs and find the right solution. To connect with our procurement and engineering teams for a consultation, reach out via the channels we’ve provided—we’re ready to talk through how the RX01 can work for you.
