PRODUCT DESCRIPTION

MDS Mercury
less network service with long range and secure operation at adaptive
data rates approaching 12 Mbps. The transceiver is ideally suited for
demanding applications in mobile or fixed environments, where reli­ability and range are paramount.

The product is commonly used to send text documents, graphics,
email, video, voice over IP (VoIP), and a variety of other application
data between mobile, fixed-point, and LAN-based entities.

The transceiver comes in two primary models—Access Point and
Remote, each with unique hardware profiles. Both models support
Ethernet and serial services. An Access Point (AP) is a wireless hub
that usually provides connectivity into a wired Ethernet LAN/WAN.
Remotes associate over the air with an Access Point and are typically
connected to an Ethernet or Serial device via a cable.

Series transceivers provide an easy-to-install wire-

INSTALLATION OVERVIEW

There are three main requirements for installing the transceiver—ade­quate and stable primary power, a good antenna system, and the cor­rect interface between the transceiver and the data device. The
Installation Setup Chart (center of this guide) shows a typical Remote
installation. Access Point and mobile Remote stations typically use
omnidirectional antennas whereas fixed-site Remotes typically use
directional antennas such as a Yagi or panel type. Otherwise, both
installations are similar.

INSTALLATION STEPS

A typical shipment consists of a transceiver, a power connector and
this start-up guide. Below are the basic steps for installing a trans­ceiver. Refer to the
tion. You will also find support information at the GE MDS Web site:

www.GEmds.com. Our Technical Services Team is available to assist

with any difficulties that may be encountered. Refer to the back of this
guide for contact information.

It is highly recommended that the Access Point unit be installed
so that you can quickly check the operation of each associated Remote
as it is placed on the air.

NOTE:

Using

Configuration Scripts

under the

Maintenance/Tools

menu will aid in uniformly configuring multiple units. See the

Mercury Reference Manual

for details.

Step 5—Connect the Data Equipment

Connect Ethernet-compatible data equipment to the unit’s

LAN

port
(10/100 BaseT), or one of the serial ports, depending on the capability
of your transceiver.

Use a straight-through Ethernet cable to connect the

LAN

port to a hub
or switch, and a crossover cable to connect it directly to an Ethernet
station (PC, PLC, RTU).

Step 6—Check for Normal Operation

This step verifies the proper operation of wireless communications
between an Access Point and its associated Remotes.

At All Units...

Observe the transceiver’s LED panel (See
for the proper indications. In a normally operating system, the radio
will typically become associated in about two minutes from start-up.

At the Access Point...

a. If the Access Point unit is the first unit you are installing, send

PING

a

command to it through the

LAN

connectivity.

b. If you have already installed a Remote unit, try sending a

to that unit through the Menu System

—The unit has successfully synchronized and associated

with an Access Point. This is the normal status.

Alarmed—The unit is has detected one or more alarms that have not

been cleared.

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 link integ-

rity with the Access Point.

d. After the

PING is successful, connect the terminal equipment

to the radio’s data port and verify normal operation.

If all checks are OK, you are finished with the installation at this site.

Resetting to Factory Defaults (Use with Caution)

Selecting Maintenance/Tools>Reset to Factory Defaults sets all trans-
ceiver parameters back to their factory defaults. This may be useful
when several parameters have been modified and there is no track of
changes. It causes the transceiver to return to a known factory state.
Use this function with care, as all user-customized settings will be
cleared.

AIMING DIRECTIONAL ANTENNAS

Directional antennas usually require some fine-tuning of their bearing
to optimize the received signal strength. The unit has a built-in
received signal strength indicator (RSSI) that can be used to optimize
the received signal level. It is available under the

tion

menu.

Packet Statistics are based on multiple samples over a period of sev­eral seconds. The average of these measurements is displayed by the
RSSI screen.

In the steps below, the path to the Menu System item is shown in bold
text.

Procedure

1. Verify the Remote is associated with an Access Point unit by
observing the LINK LED. It should be on or blinking.

2. View and record the
rates. This information will be used later.

Main Menu>Performance Information>Packet Statistics

3. Read the RSSI level at the Remote.

Main Menu>Performance Information>Internal Radio Status

4. 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.

5. View the

Wireless Packets Dropped and Received Error rates at the

point of maximum RSSI level. They should be the same or lower
than previously noted.

Main Menu>Performance Information>Packet Statistics

Wireless Packets Dropped and Received Error

If the RSSI peak results in an increase in the Packets Dropped and

Received Error numbers, the antenna may be aimed at an undes-

ired signal. Try a different antenna heading.

NOTE: Access Points and Remote stations must use the same antenna

polarity (vertical or horizontal) or signal strengths will be
attenuated by 20 dB or more.

TRANSMITTER POWER & ANTENNA TEST

The following procedure may be used to measure the transmitter’s RF
power output and SWR “match” of the antenna system. A directional
wattmeter is required for the test, such as a Bird Model 43, with an
appropriate element installed.

Before you start, keep in mind that using the Test Mode will disrupt
network operation.

Procedure

1. Connect a directional wattmeter between the ANTENNA port and
the antenna system.

2. Place the transceiver into the Radio Test Mode.

Main Menu>Maintenance/Tools Menu>Radio Test>Radio Mode>Test

NOTE: The Test Mode has a 10-minute timer, after which it will

return the transceiver to normal operation. The Test Mode can
also be terminated manually, via the menu.

3. Set the transmitter RF output power to +28 dBm.

Main Menu>Radio Configuration>Transmit Power

NOTE: The Test Mode RF power setting does not affect the output

level during normal operation

4. Activate (key) the transmitter.

Main Menu>Maintenance/Tools>Radio Test>Test Mode>
TxKey> Enable

Use the spacebar to key and unkey the transmitter ON and OFF
(Enable/Disable).

5. Using the wattmeter, measure the forward and reflected power
into the antenna system and calculate the SWR. The ratio should
be less than 2:1. Higher levels may indicate a problem with the
antenna or feedline.

6. Turn off Test Mode at the Access Point and Remote radio.

TROUBLESHOOTING

It is best to begin troubleshooting at the Access Point, as the rest of the
system depends on it for network synchronization and configuration.
If the Access Point 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 Mode Selection, Network Name, and IP
Address

• The correct interface between the radio and the connected data
equipment (proper cable wiring, data format and timing)

Table 1 provides suggestions for resolving common system difficul-

ties using the radio’s LEDs as a guide. Table 2 on Page 13 provides
guidance for using the Menu System as a tool.

If problems cannot be resolved using the guidance provided here,
review the GE MDS web site’s technical support area for recent soft­ware/firmware updates, general troubleshooting help, and service
information. Additional help is available through our Technical Sup­port Department.

When calling, please give the complete model number of the radio,
along with a description of the trouble symptom(s) that you are expe­riencing. In many cases, problems can be resolved over the telephone,
without the need for returning the unit to the factory.

FACTORY SERVICE

If return of the equipment is necessary, please contact our Technical
Support Team. You will be issued a Service Request Order (SRO)
number. The SRO number will help expedite the repair so that the
equipment can be repaired and returned to you as quickly as possible.
Please be sure to include the SRO number on the outside of the ship­ping box, and on any correspondence relating to the repair. No equip-

ment will be accepted for repair without an SRO number.

A statement should accompany the radio describing, in detail, the
trouble symptom(s), and a description of any associated equipment
normally connected to the radio. It is also important to include the
name and telephone number of a person in your organization who can
be contacted if additional information is required.

The radio must be properly packed for return to the factory. The orig­inal shipping container and packaging materials should be used when­ever possible. All factory returns should be addressed to:

GE MDS
Customer Service Department
(SRO No. XXXX)
175 Science Parkway
Rochester, NY 14620 USA

When repairs are complete, the equipment will be returned by the
same shipping method used to send it to the factory. Please specify if
you wish to make different shipping arrangements. To inquire about
an in-process repair, contact our Product Services Group using the
telephone, Fax, or E-mail information given above
