Product Overview
The R500HA Long Range RFID Reader is a uniquely addressable passive antenna that can
be daisy chained together on one CAT5 COM Port. Up to 254 unique addresses are possible.
Custom manufactured for iAutomate.com for home automation (HA) applications, the HA
Edition R500HA Long Range RFID Reader is used in conjunction with HomeSeerSoftware
or CrestronSystems (Sold Separately) and is specifically designed for detection (or
absence) of people, vehicles, and personal assets. The R500HA RFID (Radio Frequency
IDentification) Reader provides near field or long-range coverage for real-time detection of
people, pets, vehicles or anything else you can associate with one of the various RFID Tags.
The R500HA Reader communicates with either:
• A PC via a standard COM Port Running HomeSeerSoftware
• Serial Port of a Crestron System
Additional Readers can be daisy chained to permit many Readers on one CAT5 wire system.
Each Reader is range settable via software to adjust for the requirements of the room or
application. Range adjustable antennas can be discretely concealed in walls, ceilings, and
doorways to identify and track Tag activity. The R500HA can simultaneously read multiple
RFID Tags at ranges of up to 450 feet (free air), and can also register and report the
disappearance or unauthorized movement of individual RFID Tags. This model is for use
ONLY with Crestron systems or HomeSeerv1.7 or later. A FREE HomeSeerplug-in or
Crestronmodule is included with the Installer Setup Kit.
1.2 Network Wiring and Power
The R500HA Readers are connected together in a daisy chain topology. That is, Reader 1 is
connected to Reader 2, which, in turn, is connected to Reader 3, etc. Up to 254 Readers can
be interconnected in this manner. Readers are joined to one another with a single cable,
utilizing four wires to carry both data and power. Reader-to-Reader communication is
accomplished over one pair of wires via RS485 protocol; while a second pair of wires carries
power. The network of Readers can be connected to either a PC’s standard RS232 serial port
or a Crestron System (running the Crestron Software Module).

1.2 Network Wiring and Power (cont’d)
Be certain to follow all local and national codes when installing network wiring. Avoid
installing wiring near electrical and electronic equipment, high-powered equipment, motors,
and other potential sources of RF interference.
Do NOT use standard four-pair (eight wire) Ethernet Wiring Connections or
DAMAGE will result. Refer to Figure 2 or Figure 3 and ONLY connect the 4 wires
between Readers:
• Power
• Ground
• RS485+
• RS485-
These connections have been arranged in such a way that the cable forms a straight-
through connection and does not require twisting or changing of any wires between
Readers. This makes the installation of this network very simple. Since each RS485
connection between Readers is theoretically a separate network, distances between them
can be up to 2000 ft, according to the RS485 standard, depending on the quality of the
cable used. RS485 termination resistors are included in each Reader’s circuitry and
therefore do not need to be added.
The network operates at 57,600 baud, with data being sent bidirectionally. The ReaderNet
may be supplied with power from multiple points within the network, but when more than
one power supply is used; the supplies must be interconnected via the ground line.
Only the SPS1212 Power Supply may be used to power the Network. (Using any other
power supply will void the Reader warranty). Up to ten Readers can be powered with a
single SPS1212 Power Supply, which delivers 1.2A@12VDC.

1.3 Tooling and Connectorization
iAutomate.com highly recommends the EZ-RJ45 Crimp Tool and Connectors for making
trouble-free Reader terminations the very first time. This high-quality crimp tool is designed
to quickly crimp and cut the wires of the EZ-RJ45 ® Connector.in a single, simple operation.
The crimp tool also works on most other brands of RJ45 Connectors. No home automation
installer should be without this time saving tool and a bag of EZ-RJ45 Connectors.

2.1 RF Basics Relating to the R500HA RFID Reader
A typical radio-communication system is comprised of two main components, namely a
transmitter (Tx) and a receiver (Rx). The transmitter generates electrical oscillations at a
given radio frequency and the receiver detects these electrical oscillations if it is tuned to
the same frequency. The frequency used is called the carrier wave.
In general, FM radio works the same way that AM radio works; the difference is in how the
carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of
the signal is varied to incorporate the digital information. With FM, the frequency (the
number of times each second that the current changes direction) of the carrier signal is
varied.

FM signals have an advantage over AM signals. Though both signals are susceptible to slight
changes in amplitude, with an AM broadcast, these changes result in static, while with an
FM broadcast, slight changes in amplitude don't generate static. Since the FM signal is
conveyed through changes in frequency, the FM receiver can just ignore changes in
amplitude. On the other hand, AM has a distinct advantage over FM in terms of power
consumption. AM signals can be transmitted at a much lower power consumption level than
any other modulation at 433 MHz. It is purely for reasons of power conservation (longer
battery life) that AM modulation is used for the RFID Tags.
2.1 RF Basics Relating to the R500HA RFID Reader (Cont’d)
In the earth’s atmosphere, the physical characteristics of air can cause variations in the
speed at which radio waves travel. These variations can be a cause of problems in any
communication system. This is why you might notice different performances from the same
RF System on different days as the weather or atmospheric conditions change. Many natural
events (such as storms, or excessive solar activity) and man-made electrical devices can
adversely affect RF Transmissions.
Because data is transmitted in digital form from the Tag to the Reader, the norm to use is
either Amplitude Shift Keying (ASK) or Frequency Shift Keying (FSK). The R500HA RFID
Reader uses ASK as the preferred method solely because of the power saving characteristics
of the ASK technique of data coding.
2.2 RF Range and Antenna Polarization
The distance an RF Transmission will travel is primarily determined by the transmitter’s
output power and the receiver and antenna’s power (GAIN) and is influenced by
environmental conditions and structures. Although the level of available power is the main
determinant of transmission range, the manner and efficiency in which that power is
deployed will also play a role.
The design of the transmitter’s antenna determines the shape of the field delivered. The
field (or wave) delivered from an antenna extends into the space surrounding it, and its
strength diminishes with respect to distance. In any space free of obstructions or
absorption, the strength of the field reduces in inverse proportion to the square of the
distance. Effective range is also ** influenced by the angle (polarization) between the
transmitter’s and receiver’s antennas. ** For an RF wave travelling through an area in
which it can be reflected off of the ground or from metal obstacles, the reduction in strength
can be quite considerable. Where different travel paths are created in this manner, the
phenomenon is termed “multi-path attenuation.” Absorption of RF Energy due to the presence of
moisture, both in the atmosphere and in objects in the environment can further influence effective range.
It is VERY important to determine how the environment, both internal and external, can
influence the range of the R500HA RFID Readers before permanently installing wiring or
mounting the Readers. We recommend temporary wiring and temporary mounting of
antennas as a method of range testing the components while connected to the PC to
determine the best locations for optimum signal strength and range.

2.2 RF Range and Antenna Polarization - Continued
It is far better to find a Reader location that will afford maximum range, and then tune the
Reader down if necessary, as opposed to selecting a weak location and then trying to boost
the signal, which might be impossible.
Here is an example of the coverage pattern of the R500HA Reader when using the supplied
dipole (whip) antenna. This is how the pattern would look with the Reader mounted
vertically. The tip of the antenna is where X & Y intersect in the center of the “Donut.”:
Note that the pattern is both horizontal AND vertical. Care must be taken to place readers is
such a way that tags are not detected from a floor above or floor below.
Figure 5

R500HA R500HA Reader Installer Manual Page 8 of 31

Look at what happens to the pattern if you lay the R500HA Reader flat, or at a 90 Degree
angle from vertical:
Figure 6
Effective range is influenced by the angle (polarization) between the transmitter’s and
receiver’s antennas. Because of this, the same holds true for the orientation of the Tags as
for the Reader. By orienting the Tags at different angles (polarization) to the antenna, you
can impact the range and performance of the Tags. For Maximum range, the angle of
polarization of the Tag and R500HA RFID Reader should be the same.
In some instances the wiring between Readers can function as part of the antenna. For this
reason it is required that field wiring be installed in such a way that Tags do not come in
contact or near contact with the field wiring in the course of normal activity. Since such
interference cannot be avoided, ferrite chokes are supplied which will snap over each of the
CAT 5 cables at each reader as shown in Figure 7.

Initial trial with temporary wiring for signal strength showing Reader locations centralized under internal
rooms but favoring outside (driveway) wall of Garage to maximize Automobile Tag Range. A variety of
antennas are available for longer range and exterior applications. Note that the R500HA Reader antenna
may be removed when only near field detection is required, or the desired range cannot be lowered
enough via software.
