FCC Notice, U.S.A.
The MDS iNET 900 transceivers comply with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Only install this device in accordance with the instructions outlined in this manual.
Failure to comply with these instructions may also void the user’s authority to operate
this device.
Furthermore, this device is intended to be used only when installed in accordance with
the instructions outlined in this manual. Failure to comply with these instructions may
also void the user’s authority to operate this device.
FCC Information
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
ABOUT THIS MANUAL
This guide presents installation and initial operating instructions for
the MDS i NET 900™ transceiver. Following installation, we suggest
keeping this guide near the equipment for future reference.
The scope of this manual is limited to the safe and effective installation
of the unit in typical office or non-hazardous industrial settings. Users
who require optimization of the equipment’s capabilities and operating range should read the MDS iNET 900 Network Administrator’s

PRODUCT DESCRIPTION
The MDS i NET 900 transceiver is designed to provide network managers with a easy-to-install wireless local area network (LAN) services
with plug-and-play hardware.
The unit can be reconfigured for any one of three standard operating
arrangements; some require the use of authorization keys (alphanumeric code) purchased from MDS. The model descriptions reflect
their operating mode capabilities. Supported data interface services
are one of three arrangements: 1. Ethernet, 2. Serial, and 3. Ethernet
and Serial. (See Table 1 on page 4 for a summary of core interface services.)

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.

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.
