Connect to +24V DC (range: 16V to 32V DC). Connect Terminal 2 to 0V / Common.
Ensure the sensor cartridge (catalytic, IR, or toxic) is appropriate for the target gas.
Selects an option, confirms a choice, or enters the main menu. 6. Step-by-Step Gas Calibration Procedure Xnx Universal Transmitter Quick Start Guide
After about 30–60 seconds, the unit will enter normal monitoring mode, displaying the current gas concentration. 4. Navigation and Magnetic Wand
Ensure at least 6 inches (150 mm) of clearance below the sensor for easy replacement and calibration adapter attachment. 3. Electrical Wiring and Connections Ensure the sensor cartridge (catalytic, IR, or toxic)
| Symptom | Most Likely Fix | | :--- | :--- | | | Reverse polarity on V+ and V- (Check terminal 1 & 2) | | Reading stuck at 4 mA | Loop is open. Check wiring to PLC; jumper S to V- to test locally. | | "Sensor Missing" error | You forgot to remove the shorting plug from the sensor socket. | | Erratic reading (jumping ±10%) | Moisture inside the sensor head. Dry it with warm air; install a drip loop in the conduit. | | Modbus timeout | A and B wires are swapped. Swap Terminal 4 and 5. |
How to configure digital communications
Here is what makes the XNX—and the guide that kicks it into gear—such an interesting piece of engineering.

In a world of fragmented technology, a "Reconnector" named Leo uses the Xnx Universal Transmitter to bridge 20th-century satellite dishes with 22nd-century neural links. Using the quick-start guide, Leo calibrates the device—featuring snap-lock technology and an amber interface—to successfully synchronize old and new communication networks. This story highlights the Xnx as a tool for connecting generations of technology. Ensure the sensor cartridge (catalytic
