05-6301A01, Rev. 01 MDS Mercury Series Quick Start 1MDS Mercury SeriesSetup GuideMDS 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.NOTE: To determine whether a unit is an BS or Subscriber Unit,check the dome label on the top of the unit.Refer to the Mercury Series Technical Manual (05-6302A01) for advanced procedures and cautionary information.1.1 Connectors & IndicatorsFigure 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 WiFi service, depending on order requirements. If WiFi is not provided on an SU, the GPS connector will also be absent.Invisible place holderFigure 1. Connectors and Indicators(Standard BS shown; SU Similar)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. Figure 2 shows a typical Mercury installation.2.1 Installation StepsListed below are the basic steps for installation. It is highly recom-mended 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.Invisible place holderFigure 2. Typical Mercury Installation (SU Shown; BS Similar)2.1.1 Step 1—Mount the TransceiverUse the supplied 6-32 x 1/4 inch (6 mm) screws to attach the mounting brackets to the bottom of the radio. Figure 3 shows the mounting dimensions of the unit. Mount the radio to a stable sur-face. (Fasteners not supplied.)Invisible place holderFigure 3. Transceiver Mounting Dimensions(Dimensions for BS and SU identical)2.1.2 Step 2—Install the AntennaBase 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. 1.0 INTRODUCTION2.0 INSTALLATIONDC INPUT(1060 VDC, 4A MAX)RS-232SERIAL PORTLAN PORTSUSB PORTS(Mini-A, Type-A)GPS ANTENNACONNECTIONWiMAX RFCHANNEL 1WiMAX RFCHANNEL 2LED INDICATORPANELTO DC POWER SUPPLY(1060 Vdc)RTU/PLCLOW-LOSS FEEDLINE(To Station Antenna)PC RUNNINGTERMINALPROGRAM(Straight-ThroughCable to Radio)TO GPS ANTENNA(Provides 3.3 Vdc output)Crossover Cableto RadioANTENNA SYSTEMSubscriber: Panel Ant.Base Unit: Sector Ant.2.75˝ (7 cm)8 5/8˝ (21.8 cm)
2 MDS Mercury Series Quick Start 05-6301A01, Rev. 01Install 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.2.1.3 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 con-nector 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 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.2.1.4 Step 4—Review the Transceiver’s ConfigurationOne 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).•Password—Used for remote access and Menu System.•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.NOTE: The default password and username is admin.A unique IP address and subnet are required to access the Menu System, either through the LAN port, or remotely over-the-air.Log-in and Configuration ProcedureThe 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.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 entire Menu System is shown in Figure 4 on Page 4.NOTE: Using Configuration Scripts under the Mainte-nance/Tools menu can aid in configuring multiple units.2.1.5 Step 5—Connect the Data EquipmentConnect 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).2.1.6 Step 6—Check for Normal OperationThis step verifies the proper operation of wireless communications between a BS and its associated SUs.At All Units...Observe the transceiver’s LED panel for the proper indications (see Table 1). In a normally operating system, the radio will typi-cally 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...a. Look for the LINK LED to turn on and stay on. This indi-cates the unit has successfully associated with the net-work’s Base Station. (The may take up to 30 seconds.)b. View the Starting Information screen for the Device Sta-tus 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 associ-ated 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 obser-vation of the unit’s LEDs, connect a computer to the trans-ceiver’s data port that will be used by the local terminal equipment. Send the PING command to verify communi-cations integrity with the Base Station. d. After the PING is successful, connect the terminal equip-ment to the radio’s data port and verify normal operation.If above checks are OK, you are finished with the installation at this site.CAUTIONPOSSIBLEEQUIPMENTDAMAGE
05-6301A01, Rev. 01 MDS Mercury Series Quick Start Guide 32.2 ANTENNA AIMINGDirectional 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 Per-formance 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 dis-played by the RSSI screen. Follow the steps below to aim the antenna for best received signal level.2.2.1 Procedure1. 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 Informa-tion>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>Per-formance 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 TROUBLESHOOTINGIt is best to begin troubleshooting at the BS, as the rest of the system depends on it for network synchronization and configura-tion. 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 instruc-tions. 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 ser-vice information. Additional help is also available from our Tech-nical Services Department.2.3.1 Resetting to Factory DefaultsIn 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-custom-ized settings will be cleared. To reset to factory defaults, select Maintenance/Tools>Reset to Factory Defaults.2.4 APPROVAL INFORMATION2.4.1 FCC Part 15 NoticeThe transceiver series complies with Part 15 of the FCC Rules.
