ANTENNA SYSTEM
Subscriber: Panel Ant.
Base Unit: Sector Ant.
MDS MercuryTM Series transceivers provide an easy-to-install
wireless network service with long range and secure operation at
adaptive data rates approaching 30 Mbps. The transceiver is
designed for demanding applications in industrial environments,
where reliability and range are paramount.
The transceiver comes in two primary models—Base Station (BS)
and Subscriber Unit (SU), each with unique hardware profiles.
Both models support Ethernet and serial services. A BS is a wireless switch that usually provides connectivity into a wired Ethernet
LAN/WAN.
Subscriber Units associate over the air with a BS and are typically
connected to an Ethernet or Serial device via a local cable. The
outward appearance of the standard SU is very similar to the BS.

meters in length (328 feet). For non-PoE models, a separate DC
power cable is required to supply 10-65 Vdc.

NOTE: To determine whether a unit is an BS or Subscriber Unit,
Refer to the Mercury Series Technical Manual (05-6302A01) for
advanced procedures and additional information.
1.1 Connectors & Indicators
Figure 1 shows the connectors and indicators of a Standard BS.
These items are referenced in the installation and operation steps
that follow. Note that SU radios may have an additional connector
present for Wi-Fi service, depending on order requirements. If
Wi-Fi is not provided on an SU, the GPS connector will also be
absent.
1.2 Weatherproof Subscriber Unit
In addition to the Standard Subscriber Unit, a weatherproof Outdoor Unit (ODU) model is offered (see Figure 2). The ODU is
designed for mounting on a tower, pole, or other elevated structure, and includes an integral panel antenna.
DC power is typically applied to the ODU through a Category 5
Ethernet cable (Cat. 5E, Cat. 6 also acceptable) which provides
Power-over-Ethernet (PoE) service. The cable can be up to 100

All operating parameters and commands for the ODU are identical
to those of the indoor SU. The only difference is in the physical
installation of the hardware on its support structure.
2.0 INSTALLATION—ALL UNITS
There are three main requirements for installing all units in the
transceiver system—adequate and stable primary power, a good
antenna system, and the correct interface between the transceiver
and the data device. Figure 3 shows a typical Mercury installation.
2.1 Installation Steps
Listed below are the basic steps for installation. It is highly recommended that the BS be installed first so that you can quickly check
the operation of each associated SU as it is placed on the air.

DAMAGE
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 surface. (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 interference, 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 provided 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 negative ground systems only.
The power supply should be equipped with
overload protection (NEC Class 2), to protect
against a short circuit between its output terminals and the radio’s power connector.
NOTE: It takes about 30 seconds for the unit to fully power up,
2.1.5 Step 4—Review the Transceiver’s
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 a few minutes to associate with another unit, esp ecially if GPS is required for time synchronization.
Configuration
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 procedures 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
hub or switch; use a crossover cable to connect it directly to an
Ethernet device (PC, PLC, RTU).
LAN port to a
2.1.7 Step 6—Check for Normal Operation
This step verifies the proper operation of wireless communications
between a BS and associated SUs.
