XNX Universal Transmitter
Installation and Operation

Types of Installations
There are three basic types of installation: a single transmitter;
multiple transmitters connected to a single power source; and
multiple transmitters connected in a “daisy-chain” conguration.
Single Transmitter
This is the simplest type of installation. It consists of a single
XNX transmitter installation per power source.

Advantages:
• Maximum distance between power source and transmitter
• Smaller power source
• If a power source fails, only one monitoring point fails.
Disadvantage:
• Multiple transmitters require multiple power sources.
Multiple Transmitters Connected to a Single Power Source
This is two or more transmitters sharing a single power source
with each transmitter having its own dedicated wiring to the
power source.

Advantages:
• Maximum distance between power source and transmitters
• Fewer power sources.
Disadvantages:
• Larger power source will be needed
• If a power source fails, several monitoring points fail.
Multiple Transmitters Connected in a “Daisy-Chain”
Configuration
This conguration consists of two or more transmitters installed
in a line. The power connections are installed as an extension of
the previous transmitter, with the rst transmitter being the only
one actually wired to the power source.

Advantages:
• Less wire needed for installation
• Fewer power sources.
Disadvantages:
• Requires a larger power source
• Shorter distance between power source and transmitters.
• If a power source fails, several monitoring points fail.
