XNX Transmitter Installation Manual
XNX is a very adaptable transmitter that is designed to take signals from any spectrum that utilizes gas sensors. It is able to provide a range of output signals that are industry standard. This lets users be able to have one type of interface for all of their gas detection requirements regardless of the different detectors used to meet the unique gas detection needs on site.
XNX Transmitter Configuration
XNX includes three main personalities that support different types of sensors. The character board and optional output interfaces are housed within the electronic POD. The persona, options, and Displayed define the behavior of the XNX transmitter depending on the type of sensor connected to it as well as the output option selected.
The MV (millivolt) persona is utilized for all mV input sensors, such as MPD as well as sense point HT. PPM, and Model 705. This EC personality is designed to work together with XNX EC Oxygen and toxic sensors. When IR ( infrared ) is utilized with the Search Line Excel and open paths and optim plus points, they interfere in the presence of gas detectors.
The different types of XNX transmitters installed
There are three kinds of installations.
Single transmitter: This is the simplest type of installation. It’s comprised of a single XNX transmitter and power source.
Multiple transmitters linked to a single source of power A pair of transmitters share one Power source. Each one has its own wiring connected connecting to the Power source.
Multiple transmitters linked to each other in a “Daisy-chain” configuration. It consists in two or more transmitters placed in an orderly line. The power connections are made to extend the first transmitter, the initial transmitter being the one connected directly to the source of power.

Plug-in module ‘POD’ removers that allow an access point to terminals.
Blocks that are removable for plugs and sockets to make wiring easier.
In general XNX Universal Transmitter is a gas detection system that is specifically designed for use in hazardous areas and utilizes multiple sensor techniques, such as catalytic beads electrochemical, infrared, or to identify explosive, toxic gas, and oxygen depletion dangers. Each technology is equipped with a distinct personalization board. Electrochemical technology is utilized in conjunction with the XNX electrochemical board. EC sensors use the trademarked Reflex cell fault diagnostic routine. Reflex tests for cell presence dry-out of cells, short circuits in the cell. The transmitter will automatically start the reflex every eight hours. The process is also initiated upon start-up or when sensors fail to detect fault codes. For more information on any type of sensor you can refer to the datasheet for the sensor that is supported.
