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 43 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.
