5 Deploying the NCL1135
The following section describes tests that you can use to optimize the signal strength and align
the NCL1135 antennas after they are set up and transmitting.
NOTE: You cannot run more than one test at a time at a given unit.
5.1 Optimizing Signal Strength
5.1.1 Running the Continuous Transmit (Tx) Test
This test should only be used when setting up a Master and the first Station of a new network.
The purpose of this test is to send a continuous stream of messages from an NCL1135 Master
to a Station which receives and discards the messages, or to a spectrum analyzer for signal
monitoring. The Radio Packet Error Rate (PER) is displayed at a Station receiving the
Continuous Transmit messages and using that information, an installer aligns the antenna
accordingly. Refer to
Displaying the Radio Packet Error Rate (PER) , on page 41 for more
information.
You will need one NCL1135 configured as a Master. At the other end of the link, you can have
an NCL1135 Station or a spectrum analyzer. The following procedure describes the test for a
Master NCL1135 and one Station NCL1135. If you are using a spectrum analyzer, adjust the
antenna for maximum received signal.
CAUTION: Do NOT run this test in a working network. Doing so will cause every
device in the network to slow down.
