Installing the ThinkRF R5550
Installing the ThinkRF R5550
Ensure that you read and understand the following information about safety and
electrostatic discharge before you unpack and install the R5550.
Warning: Only trained and qualified personnel should be allowed to install or replace this
equipment. Read the installation instructions before you connect the system to its power
source.
Preventing Electrostatic Discharge Damage
Electrostatic Discharge (ESD) is a single-event, rapid transfer of electrostatic charge
between two objects, such as an operator and a piece of electrical equipment. ESD can
occur when a high electrostatic field develops between two objects in close proximity.
ESD occurs when electronic components are improperly handled and is one of the major
causes of device failures in the semiconductor industry.
Electrostatic discharge is more likely to occur with the combination of synthetic fibers and
dry atmosphere. Always follow these steps to prevent ESD.
Warning: Never open the front or rear panels of the R5550 as personal injury may result
and opening the chassis will void the warranty. There are no user-serviceable parts
inside. Always contact ThinkRF support for service through the online support form at
http://www.thinkrf.com/support/.
Caution: To prevent ESD, wear an ESD-preventive wrist strap that you provide, ensuring
that it makes good skin contact.
Caution: Do not touch any exposed contact pins or connector shells of interface ports
that do not have a cable attached. If cables are connected at one end only, do not touch
the exposed pins at the unconnected end of the cable.
Unpacking the Box
The following table lists the items that come with your R5550 analyzer. If any of the items

12 ThinkRF R5550 Real-Time Spectrum Analyzer User Guide
Connecting to the R5550
Connecting to the R5550
The R5550 analyzer is a network device and typically all communications with the R5550
analyzer are via a Gigabit Ethernet connection, either directly to a computer or across an
IP network. The R5550 analyzer's Gigabit Ethernet connection provides control and
status of the R5550 using SCPI commands and data using the VRT protocol.
This section provides instruction for different methods of connecting to the R5550 via its
Ethernet port and obtaining its IP address.
Deciding on Your Network Topology and IP Address Allocation
Note: To connect with the R5550 analyzer via its Ethernet port, you must decide on both
the topology of your network connection and how your R5550 obtains its IP address.
As illustrated in the following picture, the R5550 supports any IP network topology
connected via its Ethernet port including:
a direct connection to a computer across an RJ-45 Ethernet cable as per the
Connecting the R5550 Analyzer Directly to a Computer section;
a connection across a routed local network, whether on the same subnet or
across different subnets or across a routed wide-area network such as the
Internet, as per the Connecting to the R5550 Analyzer Across a Network section.
The R5550 analyzer also supports different methods of obtaining its IP address including:
dynamic IP address allocation via the Dynamic Host Configuration Protocol
(DHCP), which is applicable to a routed network topology that has a DHCP
server;
dynamic IP address allocation via the Automatic Private IP Addressing (APIPA)
protocol (otherwise known as Auto-IP), which is applicable for where a DHCP
server is not available. This method allows a direct connection to a computer that
supports Auto-IP or to a local network using a switch. With Auto-IP, a host
13 ThinkRF R5550 Real-Time Spectrum Analyzer User Guide
Connecting to the R5550
network device randomly assigns itself a link-local address in the 169.254.x.y
subnet when it fails to contact a DHCP server. Many operating systems (OSs),
including Windows, support Auto-IP;
static IP address allocation, which is applicable to any network topology.
Changing the Method of IP Address Allocation for the R5550 analyzer
This section provides the instruction for re-configuring one IP address allocation type to
another.
Note: The R5550 analyzer is configured for dynamic IP address allocation by factory
default.
If your R5550 analyzer is configured for dynamic IP allocation, then it may be
reconfigured for static IP address allocation using either its web administration or USB
console. Using the administration console in this scenario requires first a connection to
the R5550 via its Ethernet port, which in turn requires dynamic allocation of its IP either
by DHCP or Auto-IP.
If your R5550 is configured for static IP allocation, then it may be reconfigured for
dynamic IP address allocation using its administration or USB console or via a hardware
reset. Using the hardware reset to reconfigure to dynamic IP allocation is the simplest
method and is described in the section. Using the administration console requires a
connection to the R5550 via its Ethernet port.
Connection to the R5550 using dynamic or static IP allocation is described in the
following sections. The console usage is described in the Administration Console or To
Configure the R5550 Analyzer's IP Address section.
Connecting the R5550 Analyzer Directly to a Computer
This section provides instruction on connecting the R5550 analyzer directly to a computer
via their Ethernet ports using an Ethernet cable.
In order to connect directly to a R5550, the host PC might require a spare Ethernet
interface that is not otherwise used as its primary network connection. For example, you
may use a wireless connection for primary network connectivity or obtain a second
Ethernet card or USB adapter to connect to the R5550.
For this overview, the ThinkRF S240 Real-Time Spectrum Analysis Software is used to
connect to the R5550 analyzer. The latest version of this software can be found at http://
www.thinkrf.com/resources.
To connect the R5550 directly to your computer:
1. Decide on whether you will be using static or dynamic IP allocation. Regardless
of which method you choose, both your PC's and the R5550 Ethernet interface
must be configured for the same method of IP allocation. If necessary, configure
your R5550 to your chosen method of IP allocation following the instruction in the
section.
ThinkRF R5550 Real-Time Spectrum Analyzer User Guide 14
Connecting to the R5550
2. Connect the provided Ethernet cable to both your PC's and the R5550 Ethernet
ports.
3. Power up the R5550 and wait a minute for it to complete booting.
4. Check to ensure that either your PC's or the R5550 LINK indicator is illuminated.
If it is not then your PC may not support automatic crossover on its Ethernet
connection and you may require an RJ-45 crossover Ethernet cable as specified
in the section.
5. If you're using static IP allocation then skip to the next step. Otherwise, check the
STS LED for the Auto-IP setup completion (take a minute or longer).
Note: While the R5550 is searching for a DHCP server, the STS LED blinks yellow slowly
until it obtains an IP address either via DHCP or Auto-IP. The STS LED blinks in a green
heartbeat pattern if it has set up successfully to using an Auto-IP address.
Verify the host PC's IP configuration using the PyRF Discovery Tool. With a
Windows OS, open a Command window and type ipconfig to show the IP
addresses assigned to each interface. The Ethernet interface should show a
169.254.x.y address as seen in the following picture as an example.
6. Use the PyRF Discovery tool or the S240 Real-Time Spectrum Analysis Software
(as shown in the following figure), both provided by ThinkRF, to determine the
assigned IP address of the R5550. In order for the Discovery tool to locate the
R5550, both your computer and the R5550 must be configured for the same
subnet. If you are using Auto-IP dynamic IP allocation, then they will both be on
the same 169.254.x.y subnet. If you are using static IP and the Discovery tool
cannot locate the R5550, then you need to have prior knowledge of its static IP
address or use the USB console.
15 ThinkRF R5550 Real-Time Spectrum Analyzer User Guide
Connecting to the R5550
7. The assigned IP address may now be used to communicate with the R5550
analyzer.
Note: Link-local addresses used for Auto-IP are non-routable, so communications is
limited to devices within the local subnet. This restriction may be an issue when running
virtual machines (e.g. Mac Parallels, VirtualBox, etc.) that may be connected through
virtual routers to the host PC's physical network interface.
Note: After obtaining a link-local address, the R5550 continues to request a DHCP
address. If a DHCP server responds at a later time, the link-local address is overwritten
with the offered IP address. This new address is retained until the network cable is
physically unplugged or the R5550 is restarted.
Connecting to the R5550 Analyzer Across a Network
This section provides instruction on connecting the R5550 to a computer across a routed
local network whether on the same subnet or across different subnets or across a routed
wide-area network such as the Internet.
To connect the R5550 across a network:
1. Decide on whether you will be using static or dynamic IP allocation. Both your PC
and the R5550 do not need to be configured for the same method of IP
allocation; although to locate your R5550 using the ThinkRF Discovery tool
requires that they be on the same subnet. If necessary, configure your R5550 to
your chosen method of IP allocation following the instruction in the section. If you
are using dynamic IP allocation then your router or your network must support a
DHCP server.
2. Connect the provided Ethernet cable to both your router's and the R5550
Ethernet ports.
3. Power up the R5550 and wait a minute for it to complete booting. The sequence
of connecting and powering on are inconsequential.
4. Check to ensure that either your router's or the R5550's LINK indicator is
illuminated.
5. If your R5550 is behind a firewall or a router with firewall capability, then your
network's DHCP server is likely assigning private IP addresses (e.g. 192.168.x.x,
10.x.x.x, 1 2.x.x.x), and the firewall is likely providing some form of network
address translation (NAT) function. If this is the case and if you require access to
the R5550 from outside your firewall, then you will likely have to configure the
firewall to allow port forwarding on port 3 000 and 3 001. If necessary, consult
with your network administrator.
6. Use the PyRF Discovery tool or the S240 Real-Time Spectrum Analysis Software
both provided by ThinkRF, to determine the R5550's assigned IP address. In
order for the Discovery tool to locate the R5550, both your computer and the
R5550 must be configured for the same subnet. If you are using DHCP then you
may have to query your router's allocation tables to determine the IP that is
allocated to your R5550 MAC address. If you are using static IP and the
ThinkRF R5550 Real-Time Spectrum Analyzer User Guide 16
Connecting to the R5550
Discovery tool cannot locate the R5550, then you need to have prior knowledge
of its static IP address or use the USB console. If necessary, consult with your
network administrator.
7. The assigned IP address may now be used to communicate with the R5550.

Configuring the R5550 IP Address
The R5550 provides options for selecting whether the R5550 IP address is obtained
dynamically using DHCP or is set manually to a static address.
Caution: Please note that if the R5550 IP address is set to static IP then the only way to
communicate with the R5550 is via that IP address. If you mistakenly enter the wrong IP
address and/or subnet mask, or forget the IP address, then you can change the IP
configuration Using the USB Console or Restarting the R5550.
1. Click on the "IP Configuration" link in the left column menu of the administrative
console. The following "R5550 Device IP Configuration" web page should
appear. Once the “Apply” is clicked, the new configuration will take effect
immediately and the current configuration and web page will no longer be valid.
Updating the R5550's Firmware
This section will step you through updating the R5550 firmware. The firmware install file
contains firmware images associated with the R5550 FPGA, Linux operating system and
the embedded application. The process of updating will copy the new images to the
R5550 in addition to and without erasing the current installed images. The new install will
