The MDS iNET 900 transceivers serve as either an “Access Point” or
“Remote Gateway”. An Access Point is a wireless hub that provides
connectivity into a wired Ethernet LAN/WAN. From a radio perspective, an Access Point also serves as the radio network’s “master station” providing synchronization signaling for associated iNET 900
Remote Gateway radios.
INSTALLATION PLANNING
This section provides tips for selecting an appropriate site, choosing an
antenna system, and reducing the chance of harmful interference.
General Requirements
There are three main requirements for installing the radio—adequate
and stable primary power, a good antenna system, and the correct
interface between the transceiver and the data device. The center
Installation Reference Chart shows a typical Remote Gateway installation.
MDS 05-2873A01, Rev. D3
Installation Guide
Review Draft 3—12/17/01
Access Point stations are similar, but typically they use an omni-directional antenna and a Local-Area Network (LAN) or a Wide-Area Network connected to the LAN port. The Access Point iNET radio
provides a connection to the wired network for devices attached to the
Remote Gateways.
Antennas are a vital link in the system; they must be chosen and
installed correctly. The MDS iNET 900 Network Manager’s Manual
provides details on choosing a site and making antenna selections
INSTALLATION
A typical transceiver product shipment consists of an iNET 900 transceiver and a manual. Check the contents against the packing list
attached to the outside of the shipping box.
Below are the basic steps for installing a iNET 900 transceiver. Should
further information be required, see “IN CASE OF DIFFICULTY...”
on page 14 of this manual for information on contacting the factory.
You will also find support information at the Microwave Data System
Web site at www.MicrowaveData.com on the Internet.
NOTE:
It is recommended that the Access Point station be installed
first. In this way, it will be possible to quickly check the
operation of each associated Remote Gateway unit as it is
placed on the air.
MDS iNET 900 transceivers are shipped from the
factory set to the “Remote Gateway” mode unless they
are marked differently.
Step 1—Mount the Transceiver
Mount the transceiver to a stable surface. (Fasteners/anchors/screws
are not supplied unless specified when the order.) 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 screws to attach mounting
hardware to the bottom of the radio.
Installation Guide
MDS 05-2873A01, Rev. D3
Review Draft 3—12/17/01
Screws used to hold the mounting brackets to the radio should
be 5⁄16 inch (8 mm) long or shorter to prevent damage to the
radio’s internal PC board. If these screws are replaced for any
reason, the new screws must not exceed this length. The
radio’s case is made of a durable cast-aluminum, however, the
use of the wrong sized screws can damage the screw sockets
on the cover.
CAUTION
POSSIBLE
EQUIPMENT
DAMAGE
Step 2—Install the Antenna
The antenna and iNET 900 unit should be mounted with the antenna a
minimum of six inches (15 cm) from other equipment, especially
metallic objects.
NOTE:
Radio frequency energy generated by the iNET 900 can
interfere with the operation of nearby low-level RTU
circuits and change the reported values of the data being
monitored. For this reason, the antenna should be mounted
at least 10 feet (>3 meters) from the RTU, sensors and other
components of the system.
General information on the selection and installation of antenna systems is provided in the MDS iNET 900 Network Manager’s Manual.
Step 3—Measure & Install Primary Power
The primary power at the transceiver’s power connector must be
within 10.5–30 Vdc and be capable of continuously furnishing up to
500 mA. The optimum voltage is 13.8 Vdc. Be sure to observe proper
polarity as shown in Figure 1. A power connector is provided with
each radio suitable for use with pigtail leads.
Invisible place holder
Figure 1. Primary Power (DC) Polarity
The radio is designed to be used only in negative-ground systems. Make sure the polarity of the
power source is correct. Reverse polarity will damage the iNET 900’s circuitry and will result in permanent damage to the unit.

CAUTION
POSSIBLE
EQUIPMENT
DAMAGE
Review Draft 3—12/17/01
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.
Step 4—Review the Radio’s Configuration
There are two essential settings for iNET 900 transceivers that should
be known before placing the radio into service. They are:
Radio Operating Mode—Access Point or Remote Gateway
Network Name—Unique name of the radio network that is
used to generate the hopping pattern.
NOTE:
Transceivers are normally shipped from the factory configured as a Remote Gateway.
Unit IP Address—Must be a unique number to allow for IP
access through the Ethernet Port.
Transmitter Power Output Level—Default is 1 Watt.
Adjust as necessary for compliance with FCC guidelines.
NOTE:
A unique IP address is important if the radio’s LAN
(Ethernet) port will be used for IP-based data communications or for unit configuration.
NOTE:
The COM1 port’s only function is to provide access to the
iNET 900’s management system. COM2 is not functional at
this time.
The following is a summary of the installation procedure. For more
detailed instructions on using the menu-based COM1 and the
HTTP/Bowser interfaces, please read the MDS iNET 900 Network
Administrator’s Handbook.
Procedure
a. Connect a personal computer’s serial communications port
(COM1 or COM2) to the COM1 Port connector on the radio
transceiver. (See the Installation Reference Chart for location.
Data defaults: 19,200 kbs/8N1.)
b. Launch a terminal emulator program, such as HyperTerminal,
on the computer.
c. Depress the ENTER key. The radio will respond with the
start-up screen of a text-based Management System.

Review Draft 3—12/17/01
d. A login with password will be required to make any changes
to the radio. (Default = admin)
e. Select the desired options to review existing settings and to
initiate necessary changes such as the IP address and other
network parameters. Changes are saved in the unit’s flash
memory.
f.
Repeat the above steps for each transceiver in the network.
Basic iNET Unit Parameter Defaults
The table on the center Installation Reference Chart provides a summary of basic operating parameter’s range of and default values. All
of these are available through the iNET’s Management System accessible through a terminal emulator connected to the COM1 port.
Step 5—Connect the Data Equipment
Connect Ethernet/IP-compatible equipment data equipment to the
transceiver’s LAN port. The port supports only 10BaseT.
Use only the required pins for the application—do not connect anything to unused pins. Use a straight-through Ethernet cable to connect
to a hub or a crossover cable to connect directly to an Ethernet station
or RTU. See the Installation Reference Chart in the middle of this
guide for pinout information.
Remote Gateway—If the radio network seems to be operating properly based on observation of the unit’s LEDs, connect the user data
equipment to the LAN port. Use the IP PING command to verify the
communications link integrity with the Access Point unit.
Access Point—Connect the WAN/LAN to the LAN port of the radio.
LED Indicators
A table of LED functions can be found on the center Installation Reference Chart.

Review Draft 3—12/17/01
Step 6—Check for Normal Operation
a. Observe the transceiver LED status panel (See the Installation
Reference Chart) for the proper indications. In a normally
operating system, the following LED indications will be seen
within 30 seconds of start-up:
• PWR—Lit continuously
• LINK—Blinks intermittently at Remote Gateways and continuously on Access Point stations.
• LAN—On indicates it connected to a good Ethernet cable.
Blinks (flickers) with data activity.
b. Check the received signal strength indicator (RSSI) for an
adequate signal level from the radio network’s Access Point
station. (RSSI available through the iNET Management System) It may be necessary to reposition the gateway radio’s
antenna for better reception/signal strength, or if a directional
antenna is used, rotate it until the signal is optimized.
See the Installation Reference Chart for details on the LED functions
and chart of Management System menus.
If all checks out OK, you are done with the installation. Congratulations!
Performance Optimization
After the basic operation of the radio has been checked, you may wish
to optimize its performance using some of the suggestions given here.
The effectiveness of these techniques will vary with the design of your
system and the format of the data being sent.
Complete instructions on using the unit’s configuration options referenced within this section are can be found in the MDS iNET 900 Network Manager’s Manual.

TROUBLESHOOTING
It is best to begin troubleshooting at the Access Point station, as the
rest of the system depends on the Access Point for polling instructions
and synchronization data. If the Access Point station 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 radio’s operating parameters,
especially Mode selection (Access Point/Remote), Network
Name, and IP Network Address
• The correct interface between the radio and the connected
data equipment (proper cable wiring, data format and timing).
Table 2 on page 12 provides suggestions for resolving system difficulties that may be experienced in the radio system. If problems persist,
contact the factory for further assistance. Refer to the inside back
cover of this guide for contact information.

a. Check for the proper supply voltage at the power
connector.
b. Cycle the power and wait for the unit to reboot.
(≈ 30 seconds)
Interference is
suspected.
a. Verify that the system has a unique network name.
A nearby systems (Access Point station) with the
same network name will cause interference.
b. If omnidirectional antennas are used on, consider
changing to directional antennas. This will often
limit interference to and from other stations.
c. The installation of a filter in the antenna line may
be necessary. Consult the factory for further
assistance.
The LINK LED
does not turn on.
a. Check for secure interface connections at the radio
and the connected device.
b. Check the antenna, feedline and connectors.
Reflected power should be less than 10% of the
forward power reading (SWR ≈2:1 or lower).
c. No synchronization with Access Point, or poor
overall performance. Check RSSI level.
Cannot pass IP
data to WAN.
a. Use the PING command to test communication
with iNET units in the local radio system.
b. If successful with local PING, attempt to PING an
IP unit attached to an iNET radio.
c. If successful with the LAN PINGs, try connecting to
a known unit in the WAN.
