Revision D.2

Quick Start Procedure
Note: Prior to starting the installation process, go to the KTS Wireless website
(ktswireless.com) and download a copy of the ATR Element Management System (EMS)
software. Store this software on your PCs Desktop.
Follow the steps below to install and configure Agility Telemetry Radio (ATR):
1. Select the location for the ATR. Must be an area free of water intrusion with a
temperature range of -30 to +60 deg C (-22 to 140 deg F). It is always best to use the
mounting option shown in Figure 1 below to provide good ‘heat sinking’ of the ATR case
to a large metal surface or DIN rail. This will reduce the operating temperature of the
ATR and surrounding equipment within the same enclosure.
Figure 1: ATR Optional Mounting Bracket
See the KTS website for ordering information. Correct mounting is critical to maximizing
ATR performance and reliability.
2. Locate the coaxial cable to the antenna. This should be a good quality, low-loss cable
that is as short as possible. This cable should include an in-line surge arrestor to prevent

lightning strike damage to the radio. The cable should have a BNC (F) connector or an
adapter will be needed. See the KTS Wireless website for ordering information, if one is
needed.
3. Locate the power source. The ATR requires a 9-24 VDC input and draws about 2.5 A (at
12 VDC) when transmitting. Power is supplied via the Green Terminal Block at the end
of the unit (See Figure 2). The mating terminal block connector is supplied with the ATR
and can be used to connect to an existing power supply. Alternately, a separate power
supply (12 or 24 VDC) can be purchased directly from a OEM supplier provided it meets
the FCC or other regulatory requirements when powering the ATR.

Figure 3: ATR Power Connections
Note that the radio is powered using pins 1 and 3 and accepts any voltage from 12 to 24 VDC.
Pins 2 and 3 can be used to connect to an external fan near the radio if additional cooling is
required. A thermostat inside the ATR will turn the fan on and off based on its internal
temperature. The maximum current supported (internal fuse) for the fan is 0.75 A at 12 VDC.
4. Once the power is supplied to the ATR, observe that the green power LED is illuminated.
It takes about 7-10 seconds for the ATR to boot-up. After this, only the green power LED
should be on. Figure 4 summarizes the LEDs and their meaning.

6. The Main screen will appear (See Figure 6). Enter a valid password and click on Login.
The IP Tab will open if a valid password is entered. Contact KTS Wireless to obtain your
password. Section 4.0 of this manual contains the details of using the ATR Element
Management System (EMS). Jump to Section 4.0 for details on setting up the EMS and
resetting the ATR IP addresses (i.e., changing from the default value).
7. The default IP address of the ATR is 192.168.1.4. This address is automatically loaded
in the Connect to field at the top. Click on the GET button at the bottom if this default
address is still loaded in the ATR and not been changed. Note: Pressing and holding
the recessed Reset button (See Figure 4) for at least 12 seconds will force the radio
back to its default settings. The default radio IP address is 192.168.1.4.
If the ATR’s IP address is unknown, clicking on the ‘magnifying glass’ icon to the right of
the ‘connect to’ will initiate a search. If it is discovered in the search, a pop-up window
will appear with the unit’s serial number and IP address.
8. Open the Configuration Tab. Select the Link Configuration (channel bandwidth) from
the pull-down menu. Enter the desired Frequency in Hz (with or without commas
separators). Make sure the desired frequency is supported by the RF Card installed in
the ATR. The following ranges are supported:
RF Card Band Frequency Range (MHz)
VHF 145.0 to 225.0 (Band 15 or 26)
UHF 450.0 to 470.0 (Band 28)
The ATR configuration printed label (on the bottom side) indicates the RF Band
supported (VHF or UHF). Verification of the Radio band can be found on the SW/HW
tab (RF Band is displayed in the upper right of the tab).
9. Set the Transmit Power level. Valid entries are 10 to 37 (dBm).
10. Enter the Radio Type (Remote or Hub). All networks require a single hub. This Hub
radio controls the Media Access Control (MAC) software and implements a round-robin
polling of all remote sites that have ‘joined’ the network. All remote sites automatically

join the Hub/network if they are configured with the same frequency and link
configuration as the hub and have sufficient signal strength to communicate with it.
11. Enter the Site Name (optional). This is a convenient name for the location or site and
can be used by operation staff for identification. Its value does not affect radio
operation. Up to 15 characters can be entered. This name is used by the optional
Network Performance Software (NPM) to display the status of sites and send alerts. It is
recommended that a unique name be given to each site.
12. Click on SET to make the desired Configuration changes within the ATR. The ATR will
automatically reset and begin using the new configuration information. Allow about 7-
10 seconds for this process to complete. And then press the Get button to verify the
new information is stored within the ATR. This information will be saved permanently
within the ATR until changed in the future and will not be lost if the ATR looses power.
13. If the serial port is used, open the Serial Port tab. Select the desired baud rate from the
pull down menu (1200 to 38400 bits per second). This value should normally be less
than the over-the-air data rate indicated in the Link Configuration field. Select the
desired character length, parity and number of Stop bits from the pull-down menus.
The receive (from user device) and transmit (from the ATR) data can also be inverted by
the ATR by checking the associated Data Invert boxes.
14. The serial port uses a transparent mode of operation and operates as follows:
When user data is detected on the serial port, the ATR collects all bits
received into a packet of up to M bytes (configurable max packet size).
Multiple packets may be required to capture the entire message, if longer
than the configured max size.
When the port goes idle for N (configurable) character times, the packet
is transmitted over the wireless link
This feature allows the ATR to be transparent to the serial port protocol and uses data
port activity to determine when to transmit. This mode will support most serial port
SCADA protocols
15. Click on SET to make the desired Serial Port changes within the Radio.
16. The ATR should now be configured and ready for installation and operation.

1.0 Product Description
The Agility Telemetry Radio (ATR) shown in Figure 1.1 below is designed to provide a reliable
wireless connection for digital communication in the following frequency bands:
145 to 225 MHz (VHF –Band 15 or 26)
450 to 470 MHz (UHF –Band 28)
Figure 1.1: Agility Telemetry Radio (ATR)
The ATR is configured to operate in these bands only and limit its maximum transmit power to
levels outlined in Part 90 of the FCC rules and regulations. The modem functionality is
comprised of software which is loaded at the time of manufacturing. It can be upgraded in the
future to add additional features.

The unit is housed in an aluminum enclosure which is not weather-tight. Two printed circuit
boards are included: RF and Digital. The RF board is provided in one of three configurations as
outlined in Table 1 below:
RF Band Frequency Range Max Transmit Power
VHF 150.0 to 174.0 MHz 4.6 W
VHF 217.0 to 220.0 MHz 2 W
UHF 450.0 to 470.0 MHz 3.3 W
Table 1: Frequencies and Transmit Power Levels
Note: While the ATR can transmit up to 5 W, it is currently only approved for the power
levels above when used in the USA under FCC regulations (Part 90).
These RF cards all provide a common differential baseband I/Q interface to the Digital board.
The RF board includes transmit, receive, synthesizer and control sections. The transmit section
includes an Intermediate Power Amplifier (IPA), Power Amplifier (PA), Variable Attenuator and
Forward and Reverse Power Detectors. The PA provides up to 5 Watts (37 dBm) of RF output
power at the ATR antenna connector. The Variable Attenuator is used by the Control system
processor to set and maintain the transmitted RF power level. A closed-loop process is used
with the Forward Power Detector to maintain the desired output level under all conditions.
The Reverse Power Detector is used to detect impedance mismatches which may occur with an
antenna or cable failure and will automatically shut the PA down if high reflected power is
detected.
The receive section of the RF board includes a Tunable Bandpass Filter (TBPF), Low Noise
Amplifier (LNA) and Variable Attenuator. The TBPF is centered by the control processor about
the radio’s operating frequency and has a 20 MHz passband. The LNA provides gain and a noise
figure of about 4 dB.
The synthesizer section includes a 20 MHz Frequency Reference which is a Temperature-
Compensated Crystal Oscillator (TCXO) with Stratum 3 frequency stability. This reference is
multiplied up to the desired operating frequency within the Synthesizer. The output is applied

to the Digital Up and Downconverters. This provides direct modulation and demodulation of
the baseband, modulated signal.
The control section includes a processor with on-board memory, analog to digital converters
and general purpose I/O. It also includes a serial port which is used to communicate with the
processor on the Digital board. The processor manages the transmit power and programs the
synthesizer to tune to the desired operating frequency. The memory contains the processor
software along with critical calibration tables which are generated during manufacturing. These
tables provide accurate transmit power setting across the band, receive power estimation (+ 3
dB) and tunable filter control.
The Digital board provides the user ports, message routing and radio management functions.
The radio provides an RS-232 serial and an Ethernet port for connection to user devices. The
pin-out for the serial port is shown in Table 2 below.

2.0 Applications
The most common application for the ATR is a ‘star’ network where a single hub site
communicates to a collection or remote sites as shown in Figure 2.1.

Radio
Remote
Radios

Radios

Figure 2.1: Star Network Configuration
The Hub ATR is typically connected to an omnidirectional antenna via a length of coaxial cable.
The signal transmitted by the Hub ATR is then transmitted in a 360-degree pattern to all remote
sites within a range supported by the configured transmitted power. Each remote site ATR is
typically connected to a directional antenna via a length of coaxial cable. These antennas are
‘pointed’ toward the Hub to achieve maximum gain.
User devices are connected to the serial port or Ethernet connectors of the ATR. The point-to-
multipoint network shown in Figure 2.1 interconnects the Hub ATR with all remote ATRs over
the air. Media Access Control (MAC) software within the ATR allows all the radios to share the
wireless spectrum on a non-interfering basis.

The Hub ATR automatically performs the polling of all remote ATRs. This happens
automatically and transparently to the user devices. This MAC is referred to as Poll/Select.
When a remote ATR receives an IP message over the Ethernet port it is routed through a
Learning Bridge in the ATR. If this bridge determines it should be transmitted over the air, the
ATR buffers the message until the next poll is received from the Hub ATR and transmits the
message. Serial messages received are collected into a packet of up to the maximum message
size (configured by user) and transmitted after the next Hub poll. Messages smaller than this
configured maximum may be sent if activity on the serial port data line is idle for up to the
configured maximum idle character time (in characters). The most efficient serial port
configuration occurs when the maximum message forwarding size is slightly higher than the
max message size on the serial port and when the maximum idle character time configured is
slightly longer than any, normal inter-character delay on the serial port. This configuration
ensures that serial port packets are sent in a single transmission over the air.
User data transmitted from the Hub can be routed from the Ethernet port to all serial ports at
the remotes. This feature allows both user ports (serial and Ethernet) to be used
simultaneously at remotes. A UDP connection to the hub radio over the Ethernet port can be
established using port 3123 (i.e., 192.168.1.4:3123). The payload portion of these UDP packets
will be sent over the air to all remote sites in the network and forwarded to the serial port for
delivery to the attached serial devices. These devices must determine which of these broadcast
messages are for the individual device based on internal addressing. Other Ethernet traffic (not
sent to port 3123) is routed normally through the learning bridge and, if required, sent over the
air to all remotes. Each remote routes these messages to locally attached devices based on
their learning bridge forwarding tables.
Link Configurations (LCs)
Currently the ATR supports 6.25, 12.5, 25 and 50 kHz channel bandwidths using shaped, 2-FSK
modulation. The over-the-air data rates for these channel sizes are shown below:
Data Rate (kb/s) Channel Bandwidth (kHz)
4.8 6.25
9.6 12.5
19.0 25.0
38.0 50.0

Since the throughput on these wireless links is limited by the relatively narrow channel
bandwidths, it is strongly recommended that IP routers are used between the ATR and local
LANs.
