P-MP turns on. If there is traffic over the wireless medium the green Wireless Link LED should be
flashing. If the Ethernet port is active the green Ethernet Link LED should be flashing.
7. Install the Configurator program on a laptop or PC and configure your system (see Section 3). You
are going to use the antenna alignment and link monitoring screen of the program to align the
antennas.
2.8 Antenna
Alignment
There are three possible antennas that you can use with the Marquee P-MP unit:
•
An FP enclosure
•
An EX enclosure with an attached antenna
•
An external antenna
The purpose of the following steps is to adjust the Line-of-Sight (LOS) of the antennas in order to
maximize the main lobe Signal-to-Noise Ratio (SNR) level. Regardless of the type of antenna that you
are using, the procedure involves making an azimuth (horizontal) alignment and an elevation (vertical)
alignment. The steps below pertain to integrated and attached antennas, but they are also applicable to
external antennas as long as you follow the specific alignment instructions of the corresponding
manufacturer. For a P-MP configuration there are two possible cases:
•
If you are installing a P-MP configuration for the first time, you are going to align both the antenna
at the Base site and the antenna at the CPE site.
•
If you are installing a new Client in an existing P-MP configuration, you are going to align only the
antenna at the new CPE site.
IMPORTANT:
During this process, all Marquee P-MP units must be at the same stage of the installation
procedure and powered ON. It is assumed that you have configured your units (see Section 3) and that
there is communication between the Configurator program and your Marquee P-MP units. Unless
specifically noted, the term “antenna” is used to describe either of the three types.
1. Perform a coarse alignment of the antenna by using a compass heading so it is roughly “looking” at its
remote partner.
2. Connect the near end Marquee P-MP unit to the laptop or PC where the Configurator program is
installed by using a crossover Ethernet cable. Run the Configurator. Verify that the unit where you are
locally connected to as well as its remote partner are both displayed on the Main Screen (Fig. 2.12).
Note:
If you cannot see the partner Marquee P-MP unit on the Main Screen, that probably means
that your antenna is so misaligned that it cannot link to its partner. If you are setting a
new
P-
MP configuration, perform a coarse alignment of both antennas by using a compass heading
so they are “looking” at each other. Place the cursor anywhere in the
List of Scanned
Devices
box and right-click the mouse. A
Re-scan local network
button will appear. Click on
the button. If the partner Marquee P-MP still does not appear, repeat these steps until it is
displayed. If you are installing a new client on an
existing
P-MP configuration, only align the
Client antenna. The Base station antenna should
not
be touched.
3. Click
the
Analyze
tab, then click the
Wireless Link Test
button. The
Enter IP Address
window
appears (Fig. 2.13). Enter the IP address of the local unit (in this case 198.17.74.253) and a password
of
public
(unless you have previously changed it, then enter the one you defined). Click
OK
.
