Ground all antenna connections to the Sensor's ground connection point,
shown in the following illustration.
4kV of ESD protection is provided for bare antenna
connections. Protecting bare antennas from human
touch and other ESD sources will improve
reliability.
Transient arrestors are required when the antennas
are mounted outdoors, or when the system is
potentially subject to lightning surges. (Hyperlink
Technologies AL6-NMNFB-9 or equivalent.)
Preparing the Ethernet Cable
The RF Sensor uses Ethernet to communicate to the host PC.
The Ethernet connector will accept any standard 8P8C (RJ45) plug. It is
required to use a shielded LAN cable to prevent excessive emissions from the
cable.
To use the weatherproof boot in outdoor installations, the RF Sensor end of
the Ethernet cable must use a connector that does not have a bump, flange, or
tabs in the crimp section.
The illustrations show an incompatible RJ45 plug and a compatible RJ45 plug.
