Savi Fixed Reader
SR-650-101 Installation
2
Installing the Savi Fixed Reader SR-650-101 is a four-step process.
◆First, consult a site plan to determine the reader’s installation location.
◆Second, position the reader to enable the most efficient communication
range.
◆Third, connect power cables and network cables, and supply power.
◆Finally, verify network communication between the reader and the
computer.
Planning a Site
To plan a site you must conduct a site survey and plan the RFID network
configuration. Once the site plan is in place, refer to it to determine where to
install Savi Readers. Follow the directions in this manual to ensure proper
installation of each Savi Fixed Reader SR-650-101.
Positioning Savi Fixed Readers
Savi Fixed Readers are designed to operate in a wide variety of
environments. They are housed in rugged, weatherproof enclosures. In ideal
conditions (large, open, and unobstructed areas), Savi Readers can collect
tags up to 300 feet (91.44 meters) away.
An area can contain factors that limit the Savi Reader collection range,
including:
◆Asymmetrical shape to the collection area
◆Obstructions such as multiple walls, chained areas, solid-core doors, and
enclosures
CHAPTER 2
Savi Fixed Reader SR-650-101 Installation
14
◆RF interference from other equipment such as computers, walkie-talkies,
cellular phones, elevators, electrical motors, or other RF-emitting
devices
◆Savi Fixed Reader SR-650-101 mounting height of less than 15–30 feet
(4.572–9.144 meters)
◆Metal or RF-absorbent surface on the tracked item
◆Tag location relative to the Savi Reader, such as behind a metal
obstruction (as illustrated in Figure 2-1) or stacked under multiple layers
Some of these factors may be beyond your control. The goal when
positioning the Savi Fixed Reader SR-650-101 is to optimize advantages
and reduce limitations to make the collection range as efficient as possible.
Figure 2-1 Impediment limiting the Savi Fixed Reader SR-650-101 collection range
If the location forces you to use a less-than-ideal position for the reader, the
collection range could be reduced, requiring additional readers.
Note:
If you must mount a Savi Fixed Reader on a wall, the collection
range may not extend to the opposite side of the wall. You may need a
second Savi Reader to monitor the area behind the wall.

Mounting the Savi Fixed Reader
Savi Fixed Reader SR-650 Installation Guide 15
The collection range of the equipment depends on surrounding obstructions
that may shield tags from receiving reader signals or cause reflections into
locations outside the line-of-sight. As a first step, it is best to identify reader
installation locations using a line-of-sight model to any assets equipped
with tags. You may need to experiment to cover the desired area.
To optimize performance:
◆Locate the reader approximately 15 to 30 feet above the ground.
◆Avoid installations within 6 feet (2 meters) of metal surfaces, such as
temporary buildings or large steel doors.
Caution:
The Reader must be mounted in a horizontal plane with its dome
directed downwards, as shown in Figure 2-1. Other orientations will
distort the field patterns and make performance unpredictable. Maintain
the horizontal orientation when using the wall mount kit, tripod, or other
mounting hardware.
Mounting the Savi Fixed Reader
You can mount the Savi Fixed Reader SR-650-101 using any of the
associated mounting hardware available from Savi Technology. However,
you might want to be sure that the reader is operational and verified on the
network before mounting it in any hard-to-reach position.
The mounting kit available from Savi Technology includes hardware to
mount a Savi Fixed Reader on a pole (wooden, metal, or concrete), I-beam,
wall, or a tripod. Refer to the instructions included with the mounting kit for
proper installation.
RFID hardware can be physically attached in any position or location. If
your installation requires a special attachment, Savi can develop and
manufacture a custom fixture.
If you have problems communicating with the Savi Fixed Reader during or
after the installation, refer to Chapter 3, “Maintenance,” for troubleshooting
procedures.

Connecting Power Cables to the
Savi Fixed Reader
Note:
While the Savi Fixed Reader SR-650-101 is rated for use in severe
environments, the power and network connector seals may deteriorate
with repeated installation and removal. Therefore, Savi recommends the
use of heat shrink tubing (Savi part number 680-02423-001) for units
subject to outdoor use.
When connecting the Savi Fixed Reader’s power cable, be sure to check
any relevant configuration or wiring diagrams beforehand.
The power source can be 12 to 24 VDC or 92 to 250 VAC. The socket-
outlet should be installed near the equipment and should be easily
accessible. The Savi Fixed Reader SR-650-101 does not require adjustment
or modification for different power sources. An appropriate power cable is
supplied, based on the requirements specified when the order was placed.
You can also power the Savi Fixed Reader SR-650-101 from a Savi Solar
Power Module or by vehicle power. A fixed-length, molded cable is
supplied with the Solar Power Module. You can purchase the Vehicle
Power Cable as an accessory item.
The appropriate power cable for the AC power source should be included
with the reader.
To connect the power cable to the reader:
1. If installing the Savi Fixed Reader SR-650-101 in an outdoor location,
slide heat shrink tubing onto the power cable before connecting the
cable to the reader. Follow the instructions included with the heat shrink
kit to apply the tubing to the cable.
2. On the Savi Fixed Reader, plug the cable’s female connector into the
power input socket. See Figure 2-2.
a. Turn the connector to align its notch on the side nearest the Savi
Fixed Reader’s dome.
b. Firmly push the locking ring forward and rotate it clockwise to lock
the connector.
