PRODUCT DESCRIPTION

The MDS iNET-II and iNET transceivers are designed to provide wireless local area network (LAN) service with plug-and-play hardware. The transceivers come in two primary models—Access Point and Remote.

Three types of Remote Gateways are available—the Ethernet Bridge, the Serial Gateway, and the Dual Gateway supporting both

IP/Ethernet and serial services. Table 1 summaries the different interface abilities for each type of radio.

A transceiver can be configured by the owner to operate as an Access

Point or as a Remote with some restrictions. Only the Dual Gateway

Remote units can be reconfigured as an Access Point. Ethernet Bridge and a Serial Gateway Remotes cannot be reconfigured as Access Point unless they are first upgraded to Dual Gateway type. This is accomplished with an “Authorization Key” purchased from the factory. Each one of these individual software keys is associated with the serial number of the corresponding unit.

3. Can be configured as an Access Point or Dual Gateway through the embedded Menu System.

Transceivers serve as either an “Access Point” or “Remote.” An

Access Point (AP) is a wireless hub that usually provides connectivity into a wired Ethernet LAN/WAN. From a radio perspective, an Access

Point serves as the network’s “master station” providing synchronization data to all associated Remotes (RMT) within its network.

INSTALLATION PLANNING

This section provides tips for installation and start-up of the equipment.

General Requirements

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 Reference Chart (center of this guide) shows a typical

Remote installation. Access Point stations typically use omnidirectional antennas whereas Remotes typically use directional antennas such as a Yagi. Otherwise, the installations are similar.

INSTALLATION STEPS

A typical product shipment consists of a transceiver, a power connector and this start-up guide.

Below are the basic steps for installing a transceiver. Should further information be needed, see “TECHNICAL ASSISTANCE” on Page

20 of this manual for information on contacting the MDS Technical

Services Group. You will also find support information at the Microwave Data Systems Web site: www.microwavedata.com

.

i NET Series Installation & Start-Up MDS 05-2873A01, Rev. E

It is highly recommended that the Access Point unit be installed first.

With this plan, you can quickly check the operation of each associated

Remote as it is placed on the air.

NOTE: Transceivers are shipped from the factory set to the “Remote” mode unless they are marked differently.

Step 1—Mount the Transceiver

Mount the radio to a stable surface. (Fasteners/anchors or screws are not normally supplied.) Four threaded holes are located on the bottom of the radio that are suitable for connecting mounting hardware. Use

6-32 x 1/4 inch (6 mm) screws to attach mounting hardware to the bottom of the radio. Figure 1 shows the mounting dimensions.

Invisible place holder

7.25˝ (18.4 cm)

Figure 1. Transceiver mounting dimensions

CAUTION

POSSIBLE

EQUIPMENT

DAMAGE

Screws used to hold the mounting brackets to the radio case should be SAE 6-32 and should not extend farther than 1/4 inch (6 mm) into case. This will prevent damage to the transceiver’s internal PC board.

MDS 05-2873A01, Rev. E i NET Series Installation & Start-Up 7

Step 2—Install the Antenna

To minimize radio frequency interference, the antenna should be mounted at least nine inches (> 23 cm) from the connected device(s), sensors and other components of the system. Additional information on antenna selection and installation is provided in the

MDS iNET Series User’s Guide .

Step 3—Measure & Connect Primary Power

The primary power at the transceiver’s power connector must be within 10.5–30 Vdc and be capable of continuously providing up to

580 mA. A power connector with screw-terminals is provided with each unit. Strip the wire leads to 6 mm (0.25"). Be sure to observe proper polarity as shown in Figure 1 with the positive lead ( + ) on the left. If the transceiver is to be powered at voltages of 28 Vdc or higher, please review the User’s Guide for important recommendations.

POSSIBLE

EQUIPMENT

DAMAGE

The transceiver must be used only with negative-ground systems. Make sure the polarity of the power source is correct. Review complete power requirements in the

User’s Guide, Part No. 05-2806A01.

The power supply used with the transceiver should be equipped with overload protection (NEC Class 2 rating), to protect against a short circuit between its output terminals and the transceiver power connector.

NOTE: It typically takes about 30 seconds for the transceiver to power up, and about 20 to associate with another unit.

Step 4—Review the Transceiver’s Configuration

Two essential settings for the transceiver should be known before placing the unit into service. They are:

8 i NET Series Installation & Start-Up MDS 05-2873A01, Rev. E

•

•

Device Mode —Access Point, or Remote (default).

Network Name — Common identifier used by all of the units, which are part of the same network (required).

The Network Name must be programmed to enable Remote units to associate with the Access Point unit.

Other parameters that commonly need review or adjustment are:

•

•

•

•

IP Address —Must be a unique address to allow for IP access through the LAN port or over-the-air. (Default = 192.168.1.1)

RF Output Power Level —Check and adjust as necessary for compliance with regulatory guidelines. (Defaults: iNET=+30 dBm, iNET-II=+28 dBm.)

Data Rate — AUTO selection (default) allows maximum data rate for the current signal level. (The stronger the signal, the higher the data rate.) iNET-II data rates are 512 kbps or 1 Mbps; iNET rates are 256 kbps or 512 kbps.

Password —Used for remote access and Menu System features.

NOTE: The default password is admin . For web access, a username is also required. The default username is iNET or iNET-II in accordance with the radio model being used.

A unique IP address and subnet are required to access the Menu

System, either through the LAN port, or remotely over-the-air.

A summary of selected operating parameters’ range and default values is included in the Reference Chart at the center of this booklet.

How to Review the Transceiver’s Configuration

(

The following is an overview of the configuration procedure. For detailed instructions on using the HTTP ( LAN Port) and text-based

COM1 ) Menu System, please refer to the User’s Guide . Key menu selections are shown at the center of this guide.

a. Connect a computer’s serial communications port to the

Port. (Defaults: 19,200 bps/8N1/No Handshaking)

COM1 b. Launch a terminal emulator program, such as HyperTerminal, on the computer. Configure to: 19,200 bps/8N1/no handshaking/VT100.

MDS 05-2873A01, Rev. E i NET Series Installation & Start-Up 9

c. Press the ENTER key. A login screen will be displayed that requires a password (default = admin ) to access the Menu System. A password is required to make changes to all parameters.

d. Program the radio’s Network Name.

e. Review other settings and make changes if necessary, such as the unit password, IP address and security.

Repeat the above steps for each unit in the network.

NOTE: The Menu System’s “configuration files” will aid in uniformly configuring multiple units. The use of these files is described in the User’s Guide.

Step 5—Connect the Data Equipment

Ethernet Example: Connect Ethernet-compatible data equipment to the unit’s LAN port (10BaseT), or one of the serial ports, depending on the capability of your transceiver. (See Table 1 on Page 4 .)

Use a straight-through Ethernet cable to connect the LAN port to a hub, and a crossover cable to connect it directly to an Ethernet station. See the Reference Chart at the middle of this guide for more information.

IP-to-Serial Example: From the PC, establish a TCP connection to the IP address of the Remote transceiver and to the IP port. A Telnet client application can be used to establish this connection. Data may now be sent between the PC and the RTU or other connected device.

Configure the port as shown in Table 4.

Step 6—Check for Normal Operation

In this step you will verify the proper operation of wireless communications between an Access Point and the associated Remotes.

At All Units...

Observe the transceiver’s LED panel (See Reference Chart) for the proper indications. In a normally operating system, the radio will usually become associated in less than one minute from start-up.

At the Access Point Unit...

a. If the Access Point unit 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 a Remote unit, try sending a PING to that unit through the Menu System PING utility.

At Remote Units...

a. Look for the LINK LED to turn on and remain on. This indicates the unit has successfully associated with the network’s

Access Point. (The association process may take up to 30 seconds.) b. Check the Starting Information screen for the Device Status

(also known as Connection Status). It will show one of the following:

Scanning —The unit is looking for an Access Point beacon signal.

Exp(ecting) Sync(hronization) —The unit has found a valid beacon signal for its network.

Hop Sync —The unit has changed its frequency hopping pattern to match that of the Access Point.

Connected —The unit has a radio (RF) connection with the Access

Point, but has not obtained cyber-security clearance to pass data.

Associated —This 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.

MDS 05-2873A01, Rev. E iNET Series Installation & Start-Up 11

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 the communications link integrity with the Access Point. d. After the PING command 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 Care)

This procedure 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-operational state.

To reset all transceiver parameters back to the factory defaults, including the password (default = admin ), you must enter a special code (authorization key) provided by the factory in place of the user name at the time of login. Contact the factory for more information.

Performance Optimization

After the basic operation of the network has been verified, you may wish to optimize its performance using the suggestions given below.

The effectiveness of these techniques will vary with the amount of data being handled.

Optimize Received Signal Strength

Check the received signal strength indicator (RSSI) for an adequate signal level from the radio network’s Access Point. (RSSI is available through the Menu System.) In the absence of interference, signal levels that are sufficient to provide reliable operation (with a 15 dB fade margin) are: ≥ –84 dBm @ 256 kbps, ≥ –75 dBm @ 512 kbps ≥

–65 dBm @ 1 Mbps.

If the signal levels are lower, it may be necessary to reposition the station’s antenna for better reception/signal strength.

Minimize Packet Retries

If the Wireless Packet Statistics’ retry packet counter is unacceptably high, several techniques can be used to improve it.

12 iNET Series Installation & Start-Up MDS 05-2873A01, Rev. E

These include identifying interference and taking corrective steps such as skipping some radio frequencies from the hopping pattern, increasing the gain of the Remote unit’s antenna system, relocating the

Remote’s antenna, or installing a repeater system.

Blocking Out Zones

The transceiver uses channels in the 902–928 MHz spectrum, with selectable hopping from 1 to 80 channels. This selection is available only on iNET-II or specially provisioned iNET units using the Channel

Config(uration) Submenu.

NOTE: When using CHANNELS mode, all radios (AP and Remotes) must be set to use the same channels in order to establish a link. If this is not done, the radios will not connect.

NOTE: The iNET-II operates only in the CHANNELS mode, with selectable hopping from 1 to 75 channels.

Usage key for Channel Configuration Menu: n (no) = Radio channel is not used y (yes) = Radio channel is used

NA (not available) = Radio channel is not available

Other selections on Channel Configuration Menu:

• Clear All —This command clears all entries in the Channel Config Menu, resetting the available channels to “no usage.” Channels that are not available for use will appear with a notation of or NA . These channels are not available because of pre-existing conditions, and are not user-configurable.

• Enter Channels —This allows selection of the channels used for frequency hopping operation. The selection of particular chan- nels will result in an indication of y . Be aware that these channels do not become active until the Commit Changes selection is invoked.

• Commit Changes tion.

—

This re-boots the radio and loads the active channels into the frequency list for frequency hopping opera-

MDS 05-2873A01, Rev. E iNET Series Installation & Start-Up 13

AIMING DIRECTIONAL ANTENNAS

In general, signal levels stronger than –80 dBm will provide reliable communication in the network. 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 as an aid to optimizing the received signal level. The measurement and antenna alignment process usually takes less than 10 minutes at each unit.

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 Menu System.

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 Wireless Packets Dropped and Received

Error rates. This information will be used later.

Main Menu>Performance Information>Packet Statistics>Wireless

Packet Statistics

3. Read the RSSI level at the Remote.

Main Menu>Performance Information>RSSI by Zone

4. Optimize RSSI by slowly adjusting direction of 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 the previous reading.

Main Menu>Performance Information>Packet Statistics>Wireless

Packet Statistics

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

TRANSMITTER POWER AND ANTENNA

SWR 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>Test Mode>Y>ON

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 30 dBm.

TROUBLESHOOTING

It is best to begin troubleshooting at the Access Point, because 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 Device Mode selection (Access Point/Remote), Network

Name, and IP Address

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

Table 5 provides suggestions for resolving common system difficulties using the front panel LEDs as a guide. Table 6 on Page 17 provides guidance using the Menu System as a tool.
