Hardware Installation
ACRS 2.0 is the second generation Adaptrum cognitive radio system covering spectrum bands
from 400 MHz to 1 GHz. ACRS 2.0 is specifically designed to operate in the UHF TV Band (470 MHz – 698
MHz), as TV Band Devices compliant to the rules specified in CFR 47 Part 15 Subpart H. To be rules
compliant, ACRS 2.0 systems must operate as Fixed TV Band Devices and must be professionally
installed.
ACRS 2.0 radio has a fully enclosed weather-proof aluminum construction as shown in the
following pictures. There are status 4 LEDs on the front and an SMA antenna port and an Ethernet port
on the back. The unit is powered through Ethernet and there is no separate power connector. The last
picture below shows an example pole-mount installation. Both the base and the client stations use the
same radio unit.

ACRS 2.0 system has been authorized for use with the following antenna types:
1) Log-periodic antennas with a gain of 10.15 dBi or less.
2) Bowtie antenna with backplane reflector with a gain of 11.8 dBi or less.
3) Print-circuit-board (PCB) omni-directional bowtie antenna with a gain of 2.3 dBi or less.
The antenna used with the ACRS 2.0 system must have well characterized gain. Antenna feed cable loss
should also be characterized. Please consult with Adaptrum if you have questions about what types of
antennas can be used with ACRS 2.0 radio system.

Client station installation diagram.
For both the base station and the client station installations, the ACRS 2.0 radio SMA connector
is connected to the feed cable which is connected to the antenna. The base and client radio operation
can be controlled through base control PC or client control PC connected to the radios through Ethernet
switches.
Once the hardware installation is complete, follow the instructions in the following sections to
perform the software installation on the control PC. Note if an installed radio unit is redeployed at a
differently location, the installer must reconfigure the radio coordinates to reflect the location
change.

Software Installation
The USB memory stick comes with the package contains the software installer
“AdaptrumTVBDStationInstallerSetup.exe” for the base station software installation or
“AdaptrumTVBDClientInstallerSetup.exe” for the client station software installation. The software can
run on Windows XP or Windows 7. The following describes the installation process on a Windows 7 PC.
1) On the base control PC, double click the installer executable. The following set up program will
show up. Select “Next” to continue installation.
2) Select the desired installation directory and click “Next”. The default is “C:\Program
Files\Adaptrum”
3) Select a folder in the Start Menu to place the program executable shortcut and click “Next”. The
default is “AdaptrumStation” for the base station installation.

Page 10
6) Once the installation is complete, click “Finish”.
The software installation on the client station follows the same steps except the default “Start Menu”
folder for the client station is “AdaptrumClient”.
If an installed radio unit and control PC are redeployed at a differently location, the installer
must uninstall the old software and reinstall the software on the control PC.
To uninstall the software, Use “Start” “Control Panel” “Uninstall a program” under
“Programs”. The following window will show. Right click “Adaptrum version X.XX” to uninstall the
program. Note that the version number “X.XX” may vary depending on software package installed.

Post-Installation Setup
The installer needs to perform the following steps to complete the system installation.
Base Station Setup
On the base station control PC:
1) Launch the “AdaptrumTVBD” software in “Start/AdaptrumStation/Adaptrum”. The software will
prompt connection IP address 169.254.0.9 which is a fixed IP address used to communicate with
Adaptrum ACRS 2.0 radio. Click “Connect” button to continue.
2) The software will start in the “Installer” mode where the installer can enter required
information for device registration and channel list request.
3) As shown in the following figure, in the “Database” pane, the Google TV White Space Database
web address is selected by default. This version of software shipped works with Google TV
Whitespace Database. For more information about Google TV White Space Database, please
visit
http://www.google.org/spectrum/whitespace/
and channel list location information as shown below:
. Enter the correct registration information
12
Page 13
4) Go to the “Installation” pane and enter the correct output attenuation level as discussed in
Section “Hardware Installation”. The installation pane also allows the installer to set the static IP
address for the base. Please enter the desired IP address, subnet mask and gateway as shown
below.
5) Click “Save All Settings to Target And Reboot” button shown above. This will save all the
installation information including device registration information, channel list information,
output attenuation level, base IP address, etc. to the base internal configuration flash. The
software will prompt the user to restart as shown below. Click “OK”. The next time the software
will launch in the “User” mode where all the installation options will be loaded directly from
device flash and cannot be altered.
6) Restart the software and it should launch in the “User” mode as shown in the following figures
where the installation options are loaded from device flash.
13

7) Follow the instructions in the “ACRS 2.0 User Manual” to select a channel for base station
operation.

Client Station Setup
The following steps should be followed on the client station to complete the installation.
1) Launch the “AdaptrumTVBD” software in the “Start/AdaptrumClient/Adaptrum”. The software
will start in “Installer” mode where the installer can enter client registration information on the
“Database” pane as shown in the following figure. Note that only device information and
location information is set from the client side. Other database registration information, e.g.
contact information, is set from the base side.
2) On the “Database” pane, enter the scan channel set using the “…” button right next to “Scan
Channel Set”. When “…” button is clicked, the scan channel selection window will pop up. Select
the desired channels and then click “Update Now” to update the scan channel set.
15
Page 16
3) Note that the scan channel selections should be made based on the client location. The scan
channel list usually contains the database channels near the client location and possibly other
channels that may be used by the base station
4) Go to the “Installation” pane and enter the correct output attenuation level as discussed
previously and use the “Add” and “Remote” buttons to enter the client side MAC addresses as
shown in the following figure. All devices that will connect to the client station should be
entered. Note client has fixed IP address of 169.254.0.9 which cannot be altered.
16
Page 17
5) Check the “Installation Complete” checkbox. The following prompt will show. Click “OK” button
to quit the software. This will save device registration information, channel list information, scan
channel list, output attenuation level and client MAC addresses to the device flash.
6) The next time the software will launch in the “User” mode where these installation options will
be loaded from system registry and cannot be altered as shown in the following figures. In the
“User” mode, the system will automatically scan all channels specified in the scan channel list
and once it finds an active base station signal on a particular channel, it will try to connect to the
base station and if the connection is successful, the message “Channel Search Success On
Channel…” will show in the alert area. Note that in the “User” mode, the user still has the option
to choose different scan channels.
