2.1.1 Step 1a—Mount the Transceiver (BS/SU)
Use the supplied 6-32 x 1/4 inch (6 mm) screws to attach the
mounting brackets to the bottom of the radio. Figure 4 shows the
mounting dimensions of the unit. Mount the radio to a stable sur-
face. (Fasteners not supplied.)

2.1.2 Step 1b—Mount the ODU (if applicable)
The ODU is a one-piece unit with an integrated, dual polararized
panel antenna. It measures approximately 27 cm wide X 27 cm
deep X 8 cm high.
Using the bracket on the back of the unit, mount the ODU securely
to a tower, pole or other stable surface that provides a clear path
in the direction of the associated Base Station.
2.1.3 Step 2—Install the Antenna
(Non-ODU models)
BS units typically use sector antennas, while SU’s typically use a
directional panel antenna. All antennas should be mounted in the
clear to a sturdy support. Connect the antenna’s feedline cable to
the transceiver’s WiMAX Antenna Port. To minimize RF interfer-
ence, the antenna should be at least 9 inches (> 23 cm) away from
connected device(s), sensors and other external components.
Install GPS Antenna (if required)
Install the GPS antenna in accordance with the manufacturer’s
instructions. Connect it to the GPS Port on the unit’s front panel.
2.1.4 Step 3—Measure & Connect DC Power
The DC input to the transceiver must be within 10–60 Vdc and
capable of continuously providing at least 50 watts. ODUs, except
for non-PoE units, receive power over the Ethernet cable. Power
cabling for ODUs must be properly secured to the support structure
the unit is mounted on. In addition, the ODU’s ground post must be
connected to a low impedance Earth ground.
For other models, a power connector with screw-terminals is pro-
vided with each unit. Strip the wire leads to 6 mm (1/4 inch). Be
sure to observe proper polarity with the positive lead (+) on the left,
and the negative on the right. The unit is designed for use in neg-
ative ground systems only.
The power supply should be equipped with
overload protection (NEC Class 2), to protect
against a short circuit between its output ter-
minals and the radio’s power connector.
NOTE: It takes about 30 seconds for the unit to fully power up,
and a few minutes to associate with another unit, espe-
cially if GPS is required for time synchronization.
2.1.5 Step 4—Review the Transceiver’s
Configuration
One setting must be known before beginning configuration on a
unit; The IP address. Check with your System Administrator for this
information. (Default address is 192.168.1.1) An overview of this,
and other parameters commonly needing review or adjustment are
listed below, followed by Log-in and Configuration procedures.
• IP Address—Must be a unique address to allow for IP
access through the LAN port or over-the-air.
• RF Output Power Level (BS Only)—Check and adjust as
necessary for compliance with regulatory limits. (Default
power is +30 dBm for 1800 model, +23 dBm for 3650
model.) Note that Subscriber Units auto-adjust power output
based on target receive signal level (set at the BS).
• Password—Used for remote access and Menu System.
(The default password and username is admin.)
• Frequency—Operating frequency in MHz.
• TDD Sync Mode (BS only)—Selections are: Free Run and
GPS Required.
Free Run allows rapid configuration and initial testing.
GPS Required synchronizes the BS’s transmissions to the
GPS timing. GPS Required is only needed to synchronize
multiple Base Stations.
Log-in and Configuration Procedure
The following is an overview of the log-in and configuration proce-
dures for the transceivers. A unique IP address and subnet are
required to access the Menu System, either through the LAN port,
or remotely over-the-air.
a. Connect a computer’s serial port to the unit’s COM1 Port.
b. Launch a terminal communication program, such as
HyperTerminal, on the computer. Configure it to: 115,200
bps/8N1/no handshaking/VT100.
c. Press ENTER. A login prompt is displayed that requires a
username and password.
d. Enter the username and password.
e. Review other settings and make changes as necessary,
such as the unit password, IP address, and security.
f. Under the Radio Configuration Menu at the Base Station,
set/verify the following:
Transmit Power—Settable from: -30 dBm to +30 dBm
(BS); 0 dBm to +30 dBm (SU); +23 dBm for 3650 models.
Receive Power—Target receive signal of the BS which
SUs will seek to adjust to, based on distance.
g. Under the Frequency Control Menu of the Radio Con-
figuration Menu, set/verify as required. Ensure that the
SU’s radio parameters are consistent with the BS's Fre-
quency Parameter.
Repeat above steps for each radio in the network. An overview
chart of the Menu System is shown in Figure 5 on Page 4.
NOTE: Using Configuration Scripts under the Mainte-
nance/Tools menu can aid in configuring multiple units.
2.1.6 Step 5—Connect the Data Equipment
Connect data equipment to the unit’s LAN port (10/100 BaseT), or
the serial port, depending on the type of equipment used.
Use a straight-through Ethernet cable to connect the
LAN port to a
hub or switch; use a crossover cable to connect it directly to an
Ethernet device (PC, PLC, RTU).
2.1.7 Step 6—Check for Normal Operation
This step verifies the proper operation of wireless communications
between a BS and associated SUs.
