Installation and Setup
X-320M™ User's Manual
Multiple sensors can be connected in two ways: directly connected to the unit (star topology) or “daisy
chained” (linear topology) as shown in Figure 2.2i. Many factors will determine the maximum length of
cable used to connect sensors to X-320M™. Some of these factors include, but are not limited to, the
type of cable used, the number of sensors, ambient electromagnetic noise, and sensor network
topology. Using Cat 5e cable, combined cable lengths of 600 ft to all sensors have been successful.
However, due to the uniqueness of installation environments, results may vary. Please test in the
desired environment before permanent installation.
The following are general recommendations that will maximize sensor runs and minimize problems.
Cat 5 and Cat 5e network cables have proven to be an effective and low-cost solution for long runs.
Other cable types can be used, but cable capacitance may limit the length. Figure 2.2j shows the
recommended connection using Cat 5 network cable.
Note: It is recommended to run the Data and the Gnd on the same twisted pair, while the power be run
on a single wire.
A linear topology (daisy chain) will minimize signal reflections, providing a more reliable connection and
longer cable length than a star topology.
Appropriate strain relief should be used at X-320M™ and other connections that may be subjected to
vibration, movement, or repeated handling.
Avoid sensor runs adjacent to industrial equipment power cables. These cables can have high current
