INTRODUCTION
MercuryTM
MDS
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.
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.

Step 2—Install the Antenna
Base 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.
MDS Mercury Series Quick Start
Install GPS Antenna (if required)
f.
Install the GPS antenna in accordance with the manufacturer’s
instructions. Connect it to the GPS Port on the unit’s front panel.
2.1.3
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.
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 150 watts. 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.
CAUTION
POSSIBLE
EQUIPMENT
DAMAGE
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,
and a few minutes to associate with another unit, especially if GPS is required for time synchronization.
2.1.4
Step 4—Review the Transceiver’s
Configuration
One key setting must be known before beginning configuration:
• IP Address—Must be a unique address to allow for IP
access through the LAN port or over-the-air. Check with
your System Administrator for this information. (Default
address is 192.168.1.1)
Other parameters commonly needing review or adjustment are
listed below, followed by Log-in and Configuration procedures.
• 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).
g.
NOTE: Using Configuration Scripts under the Maintenance/Tools menu can aid in configuring multiple units.
2.1.5
2.1.6
At All Units...
Observe the transceiver’s LED panel for the proper indications
(see Table 1). In a normally operating system, the radio will typically become associated in about two minutes from start-up.
At the Base Station...
a.
If the BS is the first unit you are installing, send a PING
command to it through the LAN port. This verifies basic
LAN connectivity.
b.
If you have already installed an SU, try sending a PING to
that unit through the Menu System PING utility or a
device connected to the unit on the same subnet.
At Subscriber Units...
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 local log-in and configuration
procedure using the COM1 serial port.
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.
Step 6—Check for Normal Operation
This step verifies the proper operation of wireless communications
between a BS and its associated SUs.
Free Run allows rapid configuration and initial testing.
A unique IP address and subnet are required to access the Menu
System, either through the LAN port, or remotely over-the-air.
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).
• Frequency—Operating frequency in MHz.
NOTE: The default password and username is admin.
Under the Frequency Control Menu of the Radio Configuration Menu, set/verify as required. Ensure that the
SU’s radio parameters are consistent with the BS's Frequency Parameter.
Repeat above steps for each radio in the network. An overview
chart of the entire Menu System is shown in Figure 4 on Page 4.
• Password—Used for remote access and Menu System.
• TDD Sync Mode (BS only)—Selections are: Free Run and
GPS Required.
Under the Radio Configuration Menu at the Base Station,
set/verify the following:
a.
Look for the LINK LED to turn on and stay on. This indicates the unit has successfully associated with the network’s Base Station. (The may take up to 30 seconds.)
b.
View the Starting Information screen for the Device Status and Connection Status). It will show one of these:
Initializing—This is the first phase after boot-up.
Scanning—The unit is looking for a Base Station beacon signal.
Ranging—Unit is adjusting power, timing, & frequency with a BS.
Authenticating—(When Device Authentication is used.) The SU
is authenticating to the network to obtain clearance.
Associated —The unit has successfully synchronized and associated with a Base Station. This is the normal state of the radio.
Alarmed—The unit has detected one or more uncleared alarms.
c.
When the network is operating properly based on observation of the unit’s LEDs, connect a computer to the transceiver’s data port that will be used by the local terminal
equipment. Send the PING command to verify communications integrity with the Base Station.
d.
After the PING is successful, connect the terminal equipment to the radio’s data port and verify normal operation.
If above checks are OK, you are finished with the installation at this
site.

2.2
ANTENNA AIMING
Directional antennas usually require some fine-tuning of their
bearing to optimize the received signal strength. The SU has a
built-in received signal strength indicator (RSSI) that can be used
to optimize the received signal level. It is available under the Performance Information menu.
In general, signal levels stronger than –80 dBm will provide reliable
communication in the network. RSSI measurements and Wireless
Packet Statistics are based on multiple samples over a period of
several seconds. The average of these measurements is displayed by the RSSI screen. Follow the steps below to aim the
antenna for best received signal level.
2.2.1
Procedure
1. Verify the SU is associated with a Base Station unit by
observing the LINK LED. It should be on or blinking.
2. a) View and record the Wireless Packets Dropped and
Received Error rates (Main Menu>Performance Information>Packet Statistics). This information will be used later.
b) Read the RSSI level at the Subscriber Unit (Main
Menu>Performance Information>Internal Radio Status).
3. Optimize RSSI by slowly adjusting the direction of the
antenna. Watch the RSSI indication for several seconds after
making each adjustment so that the RSSI accurately reflects
any change in the link signal strength. The less negative the
number, the stronger the signal.
4. View the Wireless Packets Dropped and Received Error
rates at the point of maximum RSSI level (Main Menu>Performance Information>Packet Statistics). They should be
the same or lower than previously noted.
If the RSSI peak results in an increase in the Packets
Dropped and Received Error numbers, the antenna may be
aimed at an undesired signal. Try a different antenna heading.
2.3
TROUBLESHOOTING
It is best to begin troubleshooting at the BS, as the rest of the
system depends on it for network synchronization and configuration. If the BS has problems, the operation of the entire network will
be affected.
All radios in the network must meet these basic requirements:
• Adequate and stable primary power
• An efficient and properly aligned antenna system
• Secure connections (RF, data & power)
• Proper programming of the unit’s operating parameters,
especially Frequency Selection and IP Address
• The correct interface between the radio and the connected
data equipment (proper cable wiring, data format and timing)
A chart of LED functions is provided on Page 4 of these instructions. Refer to the Technical Manual for suggestions on resolving
common system difficulties using the radio’s LEDs and Menu
system as a guide.
If problems cannot be resolved using the guidance provided here,
review the GE MDS website’s technical support area for recent
software/firmware updates, general troubleshooting help, and service information. Additional help is also available from our Technical Services Department.

2.4.2
RF Exposure Notices
1800 MHz Models
Professional installation required. The radio equipment
described in this guide emits radio frequency energy. Although the
power level is low, the concentrated energy from a directional
antenna may pose a health hazard. Do not allow people to come
closer than 23 cm (9 inches) to the antenna when the transmitter
is operating in indoor or outdoor environments. More information
on RF exposure is on the Internet at
www.fcc.gov/oet/info/documents/bulletins.
3650 MHz Models
Professional installation required. The transceiver described
here emits radio frequency energy. Although the power level is low,
the concentrated energy from a directional antenna may pose a
health hazard. Do not allow people to come closer than 25 cm (9.8
inches) to the antenna when the transmitter is operating. This calculation is based on an 18 dBi panel antenna. Additional information on RF exposure is available on the Internet at
www.fcc.gov/oet/info/documents/bulletins.
Resetting to Factory Defaults
In trouble cases where several menu parameters have been
changed and there is no track of changes, it may help to return the
unit to a known, factory default state. Configuration can then be
attempted again. Use this function with care, as all user-customized settings will be cleared.
To reset to factory defaults, select Maintenance/Tools>Reset to
Factory Defaults.
