PRODUCT DESCRIPTION
TheMDS i NET 900isadevicedesignedtoprovide wireless local area
network (LAN) services with plug-and-play hardware.
The unit can be reconfigured for any one of three operating arrange-
ments; some require the use of Authorization Keys (alphanumeric
code) purchased from MDS. The model descriptions reflect their oper-
ating mode capabilities. Supported data interface services are one of
three arrangements: 1. Ethernet, 2. Serial, and 3. Ethernet and Serial.
The MDS i NET 900 units serve as either an “Access Point” or
“Remote”. An Access Point (AP) is a wireless hub that usually pro-
vides connectivity into a wired Ethernet LAN/WAN. From a radio
perspective, an i NET 900 Access Point also serves as the radio net-
work’s “master station” providing synchronization signaling to all
associated i NET 900 Remotes (RMT) within its radio network.

INSTALLATION PLANNING
This section provides tips for installation of an antenna system, con-
figuring and commissioning a unit, and reducing the chance of
harmful interference.
General Requirements
There are three main requirements for installing the i NET 900—ade-
quate and stable primary power, a good antenna system, and the cor-
rect interface between the i NET 900 and the data device. The center
Installation Reference Chart shows a typical Remote installation.
Access Point stations typically use omnidirectional antennas whereas
Remotes typically use directional antennas such as a Yagi.
INSTALLATION
A typical i NET 900 product shipment consists of an i NET 900 unit, a
power connector and an installation guide.
BelowarethebasicstepsforinstallinganMDS i NET 900unit.Should
further information be required, see “TECHNICAL ASSISTANCE”
on page 19 of this manual for information on contacting the MDS Cus-
tomer Service Department. You will also find support information at
the Microwave Data Systems’ Web site on the Internet at www.micro-
wavedata.com.
It is highly recommended that the Access Point unit be installed first.
With this plan, it will be possible to quickly check the operation of
each associated Remote unit as it is placed on the air.
NOTE:
MDS i NET 900 units are shipped from the factory set to the
“Remote” mode unless they are marked differently.
Step 1—Mount the i NET 900 Unit
Mountthe i NET900 to a stable surface.(Fasteners/anchors/screws are
not supplied unless specified on the purchase order.) Four threaded
holes are located on the bottom of the radio that are suitable for con-
necting mounting hardware. Use 6-32 x 1/4 inch screws to attach
mounting hardware to the bottom of the radio.

MDS 05-2873A01, Rev. A MDS i NET 900 Installation Guide 7
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 dam-
age to the i NET 900’s internal PC board.
Step 2—Install the Antenna
To minimize radio frequency interference, the antenna should be
mounted at least nine inches (> 23 cm) from connected device(s), sen-
sors and other components of the system. General information on the
selection and installation of antenna systems is provided in the
MDS iNET 900 User’s Guide .
Step 3—Measure & Connect Primary Power
The primary power at the i NET 900’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.

The i NET 900 must be used only with negative-ground
systems.Make sure the polarity of the power source is
correct.The unit is protected from reverse polarity by an
internal diode and fuse.
The power supply used with the i NET 900 should
be equipped with overload protection (NEC Class 2 rating), to protect
against a short circuit between its output terminals and the i NET 900
power connector.
NOTE:
It typically takes about 30 seconds for the i NET 900 to power
up and be ready for operation.

Step 4—Review the i NET 900’s Configuration
Two essential settings for the i NET 900 unit should be known before
placing the unit into service. They are:
• Device Mode —Access Point, or Remote. (Default)
• Network Name— Common identifier used by all of the
i NET 900 units, which are part of the same network. (Required)
The Network Name must be programmed to enable i NET 900 Remote
units to associate with the Access Point unit.
Several other parameters commonly need to be reviewed and altered
if necessary. They are:
• IP Address —Must be a unique address to allow for IP access
through the
LAN
port or over-the-air.
• RF Output Power Level —Check and adjust as necessary for
compliance with FCC guidelines.
(Default = 1 Watt/+30 dBm)
• Data Rate —256 kbps default allows maximum distance
between i NET 900 units; 512 kbps best with signal levels
greater than –77 dBm (includes 15 dBm fade margin).
• Password —Used for remote access and certain i NET Manage-
ment System features.
NOTE: The default password is
admin
A unique IP address and subnet are required to access the
browser-based i NET Management System either through the LAN
port, or remotely over-the-air link.
A summary of selected operating parameters’ range and default values
can be found in the Basic Configuration Defaults table on the Installa-
tion Reference Chart .

MDS 05-2873A01, Rev. A MDS i NET 900 Installation Guide 9
How to Review the iNET 900’s Configuration
The following is a summary of the installation procedure. For more
detailed instructions on using the HTTP (
LAN
Port) and text-based
(
COM1
) Management System, please read the MDS iNET 900 User’s
Guide . Key parameters are highlighted on the Management System
flowchart on the Installation Reference Chart .
a. Connect a computer’s serial communications port to the
i NET 900
COM1
Port connector.
(Defaults: 19,200 bps/8N1/No Handshaking)
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 the i NET Management System.
A password is required to make changes to any parameter.
(Default =
admin
)
d. Program the i NET 900 Network Name.
e. Review other settings and make changes if necessary, such as
the unit password and IP address.
Repeat the above steps for each i NET 900 in the network.
NOTE:
The Management System’s “configuration files” will aid in
uniformly configuring multiple i NET 900 units. The use of
these files is detailed in the MDS iNET 900 User’s Guide .
Step 5—Connect the Data Equipment
Connect Ethernet-compatible data equipment to the i NET 900’s
LAN
port (10BaseT), or one of the serial ports, depending on the capability
of your i NET 900 model. (See Table 1 on page 5.)
Use a straight-through Ethernet cable to connect the i NET 900
LAN
port to a hub, and a crossover cable to connect it directly to an Ethernet
station. See the Installation Reference Chart for the
LAN
port pinout
information.

10 MDS i NET 900 Installation Guide MDS 05-2873A01, Rev.A
Step 6—Check for Normal Operation
The ojective of this step is to verify the proper operation of wireless
communications between MDS i NET 900 Access Point and the asso-
ciated Remotes. Then proceed to connect the user data equipment and
verify its proper operation through the iNET 900 network. Below are
some quick-checks that can be performed at various points in the
iNET 900 network.
At All iNET 900 Units
Observe the iNET 900’s LED panel (See the Installation Reference
Chart) for the proper indications. In a normally operating system, reli-
able LED operation will usually appear within one minute of start-up.
At the iNET 900 Access Point Unit
•If theAccess Point unit is the first iNET unit you are installing, send
a PING to the iNET AP unit through the LAN port. This will verify
basic LAN connectivity.
• If you have already installed a Remote iNET unit, try sending a
PING to that unit through the iNET Management System ping util-
ity.
At iNET 900 Remote Units
•Look for the LINK LED to turn on and remain on. This indicates the
unit has successfully associated with the network’s Access Point
unit. (The association process may take up to one minutes.)
•When the iNET 900 network seems to be operating properly based
on observation of the unit’s LEDs, connect a computer to the
iNET 900’s data port that will be used by the local terminal equip-
ment. Use the PING command to verify the communications link
integrity with theAccess Point unit.
•After the PING command is successful, connect the terminal equip-
ment to the iNET 900 data port and verify normal operation.
If all checks out OK, you are done with the installation at this site.

MDS 05-2873A01, Rev. A MDS iNET 900 Installation Guide 11
Performance Optimization
After the basic operation of the iNET 900 network has been estab-
lished, you may wish to optimize its performance using some of the
suggestionsgivenhere.Theeffectiveness of thesetechniqueswillvary
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 iNET Management System.) In the absence of interfer-
ence, signal levels that are sufficient to provide for reliable operation
with a 15 dB fade margin are: ≥–85 dBm @ 256 Kbps, and ≥–77 dBm
@ 512 Kbps.
If the signal levels are lower, it may be necessary to reposition the
Remote’s antenna for better reception/signal strength, or if a direc-
tional antenna is used, align it so that the signal is optimized.
Minimize Packet Retries
If the Wireless Packet Statistics’ retry packet counter is unacceptably
high, several techniques can be used to improve it.
Theseincludeidentifyinginterferenceandtakingcorrectivestepssuch
as skipping some radio frequencies from the hopping pattern,
increasingthe gain of the Remote unit’santennasystem,relocating the
Remote’s antenna, or installing an iNET 900 repeater system.
AIMING REMOTE DIRECTIONAL ANTENNAS
As a general rule, signal levels stronger than –80 dBm will provide
reliable communication in an iNET 900 wireless communications net-
work. Directional antennas usually require some fine-tuning of their
bearing to optimize the received signal strength. The MDS iNET 900
unit has a built-in received signal strength indicator (RSSI) that can be
used as an aid to optimizing the received signal level.
RSSI measurements and Wireless Packet Statistics are based on mul-
tiple samples over a period of several seconds. The average of these
measurements will be displayed by the iNET Management System.
The measurement and antenna alignment process will usually take 10
or more minutes at each iNET 900 unit.

12 MDS iNET 900 Installation Guide MDS 05-2873A01, Rev.A
The path to the Management System menu item is shown in bold text
below each step of the procedure.
Procedure
1. Verify the iNET 900 Remote is associated with an Access Point
unit. Observe the condition of the LINK LED.
LINK LED = On or Blinking
This will indicate that you have an adequate signal level for the
measurements and it is safe to proceed.
2. View and record the Wireless Packets Dropped and Received
Error rates.
Main Menu>Performance Information>Packet Statistics>Wireless
Packet Statistics
This information will be useded later.
3. Read the RSSI level at the Remote.
Main Menu>Performance Information>RSSI by Zone
4. Optimize RSSI (Less negative is better.) 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.
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 does result in an increase in the Packets Dropped
and Received Error, the antenna may be aimed at an undesired sig-
nal source. Try a different antenna orientation.
End of procedure
An Alternate Procedure
In the event that association cannot be quickly established using the
previous method, use the following procedure.

MDS 05-2873A01, Rev. A MDS iNET 900 Installation Guide 13
Before you start keep these points in mind:
• Placing the Access Point in this mode will disrupt the entire
network operation.
• The Test Mode has a 10-minute timer, after which it will
return the iNET 900 unit to normal operation.
•This process requires two people: one at the Access Point and
the other at the Remote location.
Procedure
1. Place theAccess Point unit into the Radio Test Mode.
Main Menu>Diagnostic Tools>Radio Test>Test Mode>Y>ON
Use the same test frequency at the iNET 900 Access Point and
Remote units. You may use any frequency within the 902–928
MHz band. Default = 915.0000 MHz
2. Turn on the Access Point transmitter.
Main Menu>Diagnostic Tools>Radio Test>Test Mode>
TxKey> Enable
User the spacebar to key and unkey the transmitter ON and OFF.
(Enable/Disable)
3. Place the Remote in the Radio Test Mode.
Main Menu>Diagnostic Tools>Radio Test>ON
Verify the frequency is the same as that used at the Access Point.
4. Read the RSSI level at the Remote.
Main Menu>Diagnostic Tools>Radio Test>RSSI
5. Optimize RSSI (Less negative is better.) by adjusting direction of
antenna.
6. Turn off Radio Test Mode at the Access Point and Remote.
Main Menu>Diagnostic Tools>Radio Test>Test Mode>Disable
NOTE: All iNET 900 Remotes in the network will need to re-asso-
ciate themselves with the Access Point before they can handle
normal data traffic when the test is completed. This may take
up to one minutes.
End of procedure

14 MDS iNET 900 Installation Guide MDS 05-2873A01, Rev.A
TROUBLESHOOTING
It is best to begin troubleshooting at the Access Point station, as the
rest of the system depends on the Access Point for network synchroni-
zation and configuration. 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 iNET 900’s operating parameters,
especially Device Mode selection (Access Point/Remote), Net-
work Name, and IP Address
•The correct interface between the radio and the connected data
equipment (proper cable wiring, data format and timing).
Table 2 on page 15 provides suggestions for resolving common
system difficulties. If problems persist, review the MDS Web site’s
technical support area for recent software/firmware updates, general
troubleshooting help, and service information. Additional help is
available through the MDS Customer Service Department.
(See “TECHNICAL ASSISTANCE” on page 19.)

unique Network Name.
b. A nearby system (Access Point unit) with the
same Network Name causing interference.
c. Remote not yet associated with an Access Point.
Check the “Status” of the unit’s process of
associating with the Access Point. Use the iNET
Management System.
d. Poor Antenna System—Check the antenna,
feedline and connectors. Reflected power should
be less than 10% of the forward power reading
(SWR 2:1 or lower).
Cannot pass IP
data to WAN. a. Verify your IP settings.
b. Loose Connection—Check for secure interface
connections at the radio and the connected
device.
c. Use the PING command to test communication
with iNET 900 units in the local radio system.
d. If successful with local PING, attempt to PING an
IP unit attached to an iNE 900T unit.
e. If successful with the LAN PINGs, try connecting
to a known unit in the WAN.
Wireless Retries
too high. Possible Radio Frequency Interference—
a. If omnidirectional antennas are used, consider
changing to directional antennas. This will often
limit interference to and from other stations.
b. Try skipping some zones where persistent
interference is known or suspected.
c. The installation of a filter in the antenna feedline
may be necessary. Consult the factory for further
assistance.

FUSE REPLACEMENT PROCEDURE
An internal fuse protects the iNET 900 unit. The fuse will be blown by
a reverse polarity of the primary DC power, an over-voltage transient
or an internal failure. The fuse should not be replaced until you are cer-
tain you are in a safe environment.
1. Disconnect the primary power source and all other connections to
the unit.
2. Remove the four Phillips screws at the corners of the bottom
cover.
3. Carefully separate the top and bottom covers.There is a flat ribbon
cable between the top cover’s LEDs and the unit motherboard.
You do not need to disconnect the ribbon cable.
4. Locate the fuse and fuse holder between the COM1 port and the
power connector. Figure 2 is a photograph of the fuse assembly.
5. Loosen the fuse from the holder using a very small screwdriver.
