Data
The MDS iNET 900 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 also serves as the radio network’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 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 installation.
Access Point stations typically use omnidirectional antennas whereas
Remotes, typically use directional antennas such as Yagis.
INSTALLATION
A typical transceiver product shipment consists of an i NET 900 transceiver, a power connector 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 an i NET 900 transceiver.
Should further information be required, see “TECHNICAL ASSISTANCE” on page 18 of this manual for information on contacting the
MDS Customer Service Department. You will also find support information at the Microwave Data System Web site at www.microwavedata.com on the Internet.
It is highly recommended that the Access Point unit be installed
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 transceivers are shipped from the
factory set to the “Remote Serial Gateway” mode unless
they are marked differently.
first.
Step 1—Mount the Transceiver
Mount the transceiver 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 connecting 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

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 i NET’s
internal PC board.
Step 2—Install the Antenna
Mount the i NET 900’s antenna at least six inches (15 cm) from
metallic objects and other electrical or electronic equipment. General
information on the selection and installation of antenna systems is provided in the
NOTE:
MDS iNET 900 Network Manager’s Manual
.
Radio frequency energy generated by the i NET 900 can
interfere with the operation of nearby low-level electronic
devices 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 connected device(s),
sensors and other components of the system.
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
500 mA. The optimum voltage is 13.8 Vdc. 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.

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 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 60 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 i NET 900 transceivers should be known
before placing the unit into service. They are:
• Device Mode —Access Point, or Remote (Default)
•
Network Name—
ciated with the 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 number to allow for IP access

LAN
Ethernet station or data communication equipment. See the Installa-
tion Reference Chart for pinout information.
Step 6—Check for Normal Operation
The first priority is to check the basic operation of data communications between MDS i NET 900 units in the network. When that seems
OK, connect the user data equipment and verify its proper operation
through the iNET network. Below are some quick-checks that can be
performed at various points in the iNET network.
At All iNET Units
The LEDs are a good place to look for indications of normal operation.
Observe the transceiver LED panel (See the
Chart
) for the proper indications. In a normally operating system, reli-
able LED operation will usually appear within two minutes of start-up.
At the iNET Access Point Unit
• If the Access Point unit is the first you are installing, try sending a
ping request to the iNET unit from a local or remote computer.
This will verify basic LAN connectivity.
Installation Reference
• If you have already installed a Remote iNET unit, try sending a
ping to that unit through the iNET Management System ping utility.
At iNET 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 several minutes.)
• If the iNET network seems to be operating properly based on
observation of the unit’ s LEDs, connect a computer to the iNET’s
data port that will be used by the local RTU/data communication
equipment. Use the ping command to verify the communications
link integrity with the Access Point unit.
• If the ping command is successful, connect the RTU/data communication equipment to the iNET data port and verify normal
operation.

If all checks out OK, you are done with the installation at this site.
Performance Optimization
After the basic operation of the iNET network has been established,
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.
•
Optimize Received Signal Strength
strength indicator (RSSI) for an adequate signal level from the
radio network’s Access Point. (RSSI is available through the
i
NET Management System) In the absence of interference, signal
levels of –80 dBm or stronger are suf ficient for reliable operation.
If the signal levels are lo wer , it may be necessary to reposition the
Remote’s antenna for better reception/signal strength, or if a
directional antenna is used, align it so that the signal is optimized.
•
Reduce Bit-Error Rate (BER)
network is unacceptably high, several techniques can be used to
improve the BER.
These include indentifying 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 an iNET repeater
system.
—Check the received signal
—If the bit-error rate of the data
USING RSSI TO AIM REMOTE ANTENNAS
The MDS iNET 900 network integrity is depends partially on stable
radio signal levels being received at each end of a data link. In general,
signal levels stronger than –80 dBm will provide the basis for reliable
communication. As the distance between the Access Point and
Remotes increases, the influence of terrain, foliage and man-made
obstructions become influential and the use of directional antennas as
Remote locations becomes necessary. 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 to tell you when the antenna
is in a position that provides the optimum received signal.
10 MDS iNET 900 Installation Guide MDS 05-2873A01, Rev . A
There are several techniques that can be used to measure RSSI at iNET
Remote units. The technique you choose to use will depend on your
available manpower and the need to maintain data traffic on the iNET
network. It is recommended that this process be completed before the
network is placed on-line.
Consider using the Method 1 procedure if the iNET Remote is
receiving a weak or unstable signal. If that is not feasible, a bit-error
rate measurements may prove to be the best alternative under difficult
conditions.
The measurement and antenna alignment process will usually take 10
or more minutes at each iNET unit.
NOTE: RSSI readings are based on multiple signal samples over a
period of several seconds. The average of this measurements
will be displayed by the iNET Management System.
Method 1—For New Network Installations
Background
The Access Point and Remote gateway units must be placed into the
test mode. This requires a data connection to each location to remotely
control the state of the distant unit outside of the iNET network. If this
connectivity is available, the iNET Management System may be used
via HTTP or Telnet and controlled by one person. The alternative is
two people with telephone or radio communications between each
location to coordinate the process.
• Use of the Radio Test Mode:
• Placing the Access Point in this mode will disrupt the entire
network operation.
• All iNET Remotes in the network will need to re-associate
themselves with the Access Point before they can handle normal data traffic.
• The Test Mode has a 10 minute timer, after which it will
return the iNET unit to normal operation.
• The iNET Access Point and Remote units must be on the
same frequency. The user can choose any frequency within
the 902–928 MHz bad. Default = 915.0000
• The test mode and your ability to change operating parameters
will time-out after 10 minutes. You do not need to login again to
continue to navigate through the Management System. You will

be prompted for a password when you request a parameter
change after your session has timed-out.
NOTE: Path to menu item shown in bold text below step.
Procedure
1. Verify the iNET Remote is associated with an Access Point unit.
Observe the condition of the

This will indicate that you have an adequate signal level for the
measurements and it is safe to proceed.
2. Place the Access Point unit into the Radio Test Mode.

Method 2—Adding iNET units to an existing network
Background
This method will not disrupt traffic through other iNET units in the
network and does not require the Access Point’s operating state to be
changed.
If the Access Point is left on-line in an associated state with other
iNET units in the network, the iNET Remote under test will not be able
to differentiate the signals received from the Access Point and any
other radio signal sources in the 900 MHz band. This could lead to
confusion and possibly misdirecting of the antenna.
Procedure
1. Verify the iNET Remote is associated with an Access Point unit.
Observe the condition of the
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 bit-error rate (BER).

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 synchronization 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 radio’s operating parameters,
especially Device Mode selection (Access Point/Remote),
Network Name, and often 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 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 18.)
