Important Notice: Outdoor Cable Assembly
Redline does not endorse or support the use of outdoor cable assemblies: i) not
supplied by Redline, ii) third-party products that do not meet Redline's cable and
connector assembly specifications, or iii) cables not installed and
weatherproofed as specified in this manual. Refer to the Redline Limited
Standard Warranty and RedCare service agreements.
Figure 3: Outdoor Ethernet Cable - SU-O Cable Connection
The weatherproof connector must be finger-tight plus 1/16th turn
only. Choose a tool suitable to avoid damaging the plastic connector.
The minimum diameter to pass the outdoor connector through a
conduit or hole is 26 mm (1 in).
3.4 Connect the SU-O to the PoE Adapter
The indoor end of this cable is terminated with a standard indoor RJ-
45 connector for connection to the indoor PoE adapter. The SU-O
Ethernet cable must be connected to the PoE port marked 'DATA
AND POWER OUT'.

Note: Refer to the RedMAX Wireless Access Subscriber Modem
Installation Guidelines (70-00068-01) for information about optional
lightning protection.
3.5 Connect Local Network Device
Connect a CAT-5E Ethernet cable RJ-45 connector to the 'DATA IN'
port on the PoE adapter. The Ethernet cable connects the SU-O to
the local network device. This can be a laptop PC, router, or other
supported network device.
Figure 5: SU-O Power and Network Connections
PoE Power Adapter Caution -- Warning to Service
Personnel: 48 VDC
Connecting customer premises Ethernet equipment directly to
the 'Data and Power Out' connector on the SU-O Power-over-
Ethernet power adapter may damage customer network interface
equipment. Customer equipment including personal computers,
routers, etc., must only be connected to the 'Data In' port on the
PoE unit. Only the outdoors Ethernet interface cable to the SU-O
can be safely connected to the 'Data and Power Out' connector.

3.6 Power-On the SU-O
Connect the PoE power adapter to a 110-240 VAC (nominal)
grounded receptacle. The SU-O is not equipped with a power switch
and activates immediately when connected to a power source. Power
is supplied to the SU-O through the outdoor Ethernet cable.
3.7 Configure SU-O and Align Antenna
Correct antenna alignment is essential in obtaining maximum
performance on the wireless link. A misaligned antenna will decrease
the received signal and you may be unable to connect to any base
station.
The SU-O must be mounted and connected to the Ethernet PoE
adapter before the antenna alignment can be completed. The
alignment must be performed in both the azimuth and elevation
planes. When possible, obtain accurate antenna pointing azimuth
and elevation angles for each installation site.
Base Station Location
For each SU-O installation, the base station antenna will be located
on a tower or building in the area.
Figure 6: Non-Line of Sight Signal from Base Station
The SU-O will receive the best signal when deployed with a visual
line-of-sight (LOS) to the base station. When LOS is not possible

from the SU-O location, the antenna may be aligned to receive base
station signals reflected from nearby buildings or other flat structures.
Azimuth Alignment
The azimuth is aligned by loosening the bolts on the pipe bracket and
rotating the antenna around the pole. If the unit is mounted to flat
surface, there is a single bolt for horizontal adjustment.
Elevation Alignment
The elevation is adjusted by loosening the vertical alignment bolts of
the mounting bracket. Most links will have an elevation of 0º and the
antenna can be adjusted using a bubble (spirit) level.
Adjusting Using Audible Tone
Following basic alignment, small adjustments should be made using
the SU-O audible alignment buzzer. The audible alignment buzzer is
disabled by default. You need a PC with an Ethernet port and a
cross-over type Ethernet cable.
1. Connect a PC to the DATA IN port of the PoE power injector.
2. Start a telnet session, and login to the SU-O. The factory default login
parameters are:
IP Address: 192.168.101.1
Username: admin
Password: admin
3. Enter the (case-sensitive) command to enable the audible signal:
set boardConfig Buzzer 1
The SU-O should now be emitting an audible signal that varies with
the received signal strength. A faster repetition rate of the buzzer
indicates a stronger signal being received from the remote-end
transmitter. Adjust the SU-O antenna by small changes first the
elevation and then the azimuth adjustments to obtain a maximum
reading.
The audible alignment signal remains active until disabled by the
operator. Enter the following command to disable the audible signal:
set boardConfig Buzzer 0
Enable the SU-O Monitor Mode
RSSI information is also available using Telnet. Enter the following
command to enable the monitor display:
monitor <ENTER>
The display is updated continuously with the latest statistics values.
Hit any key to exit from the monitor display.

Adjusting the Antenna
It is recommended to align the antenna to obtain the maximum SNR
value. The SNR (Signal/Noise Ratio) is a measure of the signal
quality, while RfRssi (Radio Frequency Received Signal Strength
Indicator) is a measure of the signal strength. Usually a higher SNR
will be coincident with a stronger signal, however, this may not be the
case when interference is present.
The SNR and RfRssi readings are available on the Telnet interface of
the subscriber station. Use the 'monitor' mode to provide a
dynamically updated display of the RSSI and other subscriber
statistics. From the root CLI mode, enter the following command to
activate the monitor display:
monitor <ENTER>
When monitor mode is active, the screen is updated continuously
with the latest subscriber statistics values. Hit any key to exit from
monitor mode.
Figure 7: Monitor Mode Screen
Note: RfRssi values are negative, and an RfRssi of -35 dBm is
stronger than -50 dBm.

Adjust the subscriber antenna by first adjusting the antenna through
complete sweeps of the elevation and then the azimuth. During these
sweeps, the SNR value should increase when aligned to a sidelobe,
decrease as the antenna is moved further, and then increase to a
higher value when the antenna is aligned to the most direct signal
path. Additional movement of the antenna will cause the SNR value
to decrease and then fluctuate as it aligns to another sidelobe.
Aligning the antenna to a sidelobe may result in low or unstable
readings. In some cases where interference is present, the optimum
alignment position based on highest SNR may not provide the
highest achieved RfRssi reading.
Once the alignment sweep has been completed, the RfRssi value
should be checked against the estimated value obtained from the link
budget. For a LOS link the measured RfRssi should be within five
dBm of the calculated value. A lower reading may indicate that the
antenna is aligned to a sidelobe. If the RfRssi is much lower than the
calculated value, this may indicate an optical LOS or non LOS path --
re. If the link is non LOS a suitable reflecting surface such as a
building or billboard must be used. For non LOS deployments, it is
necessary to install the link and perform vertical and horizontal
sweeps of the antenna to determine if the required throughput can be
achieved.
When the alignment is complete, partially tighten all bolts. Tighten
each bolt in a cross-pattern to minimize shifts in the antenna
alignment. Tighten all bolts securely.
