Introduction
The BusAlyzer is a serial communications analyzer designed
specifically for the P2 protocol commonly used by Sony,
Panasonic and other professional decks. It works with a host
computer running Windows and connects over Ethernet. The
BusAlyzer has two serial ports to monitor the exchange of
commands and responses between a controller and a deck. The
supplied Windows software displays the time stamped raw data.
Additionally, the supplied software allows you to filter and decode
the raw commands to display it in an easy to interpret manner. The
data can also be saved for later analysis.
Additionally, it can be configured to act as a two port serial to
Ethernet converter much like the JLCooper eBox. Pairing it up
with a second BusAlyzer allows you create two, bidirectional serial
links over any Ethernet connection. Since the BusAlyzer uses
TCP/IP, traffic can be routed over internal LANs, wireless LANs,
MANs, WANs and even over the public Internet. The serial ports
can be configured to either connect to a controller or deck on each
port independently.
Most configurations can be accomplished through a web page
server built into the BusAlyzer. Items such as port speed, parity,
IP address, remote IP address and TCP port are set using a
standard web browser. Settings are stored in nonvolatile memory.
Typically, the eBox functions as a server, passively waiting for
client devices to connect to it. The device can be a computer or
another BusAlyzer configured as a client. When the BusAlyzer is
configured as a client, it will actively attempt to connect to the
server BusAlyzer. Once this is accomplished, the either BusAlyzer
will pass data received from the serial ports to the remote
BusAlyzer. If there is no data received in the BusAlyzer, the
BusAlyzer will not send any TCP packets.
The unit features a 10/100 RJ-45 Ethernet connector, 2 9 pin D-
Sub connectors that can be configured for RS-422 (deck or

5
controller) and a DC power jack. The unit can be power from the
supplied power adaptor or powered from 9-12 volts DC. LED
indicators show status of Ethernet activity and serial port activity.

Configuring the BusAlyzer
Before using the BusAlyzer, it must be configured properly. There
are two ways to use the BusAlyzer:
• Remote data capture
• Serial to Ethernet converter
Remote data capture
In Remote data capture mode, the BusAlyzer connects to an RS-
422 controller (such as an editing controller) on Port A and an RS-
422 device (such as a VTR or video server) on Port B.
In this mode, the BusAlyzer receives the serial data or commands
from the receive pins (3 and 8) on Port A and passes it to the
transmit pins (3 and 8) of Port B. Additionally, the BusAlyzer
receives the serial data or responses from the receive pins (2 and 7)
on Port B and passes it to the transmit pins (2 and 7) of Port A.
The serial data is only buffered and amplified, there is no
reclocking, or other processing being applied to the serial stream.
These two serial streams are read by the BusAlyzer, time stamped
and transmitted via Ethernet to a host computer running the
BusAlyzer analysis software.
To configure the BusAlyzer for Remote data capture mode, the
following internal jumpers must be configured:
• JB4 – jumper must be in the Server position
• JB1 – jumper must be in the Analyzer position
• JB2 – jumper must be in the Analyzer position
• JB3 – jumper must be in the Analyzer position
• U6 – IC must be in the Mach position
• U10 – IC must be in the Ctrlr position

The following diagram illustrates the correct jumper configuration
for Remote data capture mode.

Serial to Ethernet converter
In Serial to Ethernet converter mode, a pair of BusAlyzers can
connect two RS-422 devices together over an Ethernet connection.
This can be done on both Port A and Port B simultaneously.
Additionally, Port A and Port B can be configured to accommodate
a controller or deck independently of each other.
In this mode, two BusAlyzers are required. One BusAlyzer must
be configured to be a Server and the other must be configured to be
a Client.
To configure the BusAlyzer for Remote data capture mode, the
following internal jumpers must be configured:
• JB4 – jumper must be in the Server position
• JB1 – jumper must be in the Analyzer position
• JB2 – jumper must be in the Analyzer position
• JB3 – jumper must be in the Analyzer position
• U6 – IC must be in the Mach position
• U10 – IC must be in the Ctrlr position

Web Page Configuration
In addition to the jumpers settings, there are internal settings that
must be configured if the BusAlyzer is to function correctly in
your application. This is done by accessing the configuration web
page.
Note: You must use Internet Explorer 6 or Safari to access the
BusAlyzers configuration web page. Other browsers such as Firefox,
Mozilla and Konqueror are not supported.
The BusAlyzers configuration web page can be accessed by:
1. Pressing the Reset button
2. Entering the BusAlyzers IP address in your web browser.
The factory default is http://192.168.254.112/.
Note: The Configuration Web Page is ALWAYS at 192.168.254.112
regardless of the Configuration Web Page setting.
Note: Since the default subnet mask of the BusAlyzer is 255.255.255.0,
you must set the IP address of your computer to match the subnet of the
BusAlyzer. You will need to set your computers IP address to
192.168.254.nnn where nnn can be any address except 112 or 114.
If you do not know what IP address the BusAlyzer is set to, the
BusAlyzer can be set to the factory defaults. This is done by
performing the following steps:
1. Holding the Reset button.
2. Switching the Power switch on.
3. Releasing the Reset button.
The factory defaults are:
IP Address 192.168.254.114
Subnet Mask 255.255.255.0
Gateway 192.168.254.198

The Link LED indicates that the BusAlyzer is properly connected
to another Ethernet device such as an Ethernet hub or a host
computer.
100
The 100 LED indicates that the BusAlyzer has negotiated a 100
megabit or 100baseTX link to the other Ethernet device.
10
The 10 LED indicates that the BusAlyzer has negotiated a 10
megabit or 10baseT link to the other Ethernet device.
Serial
There are three LEDs dedicated to serial signals.
IN
The IN LED is off when the BusAlyzer is not connected to the
BusAlyzer analysis software. Conversely, the IN LED is on when
the BusAlyzer is connected to the BusAlyzer analysis software.
The IN LED flashes when the serial port is receiving data.
OUT
The Out LED is off when the BusAlyzer is not connected to the
BusAlyzer analysis software. Conversely, the Out LED is on when
the BusAlyzer is connected to the BusAlyzer analysis software.
The OUT LED flashes when the serial port is transmitting data in
Serial to Ethernet converter mode.

Setting up the BusAlyzer analysis software
To use the BusAlyzer, power up the BusAlyzer, controller and
deck. Next, launch the BusAlyzer analysis software. If you used
the default installation settings, it will be located in:
Start | All Programs | JLCooper Electronics | BusAlyzer |
BusAlyzer.exe
After you launch the program, the following window will appear:
BusAlyzer Analysis Software

After connecting to the BusAlyzer, a typical screen shot will look
like this:
In the main window, you will notice the exchange of data between
the controller and the deck. The far left column is the Timestamp
followed by the controller data, deck data and lastly the decoded
command.
Time
This column lists the actual relative time that a byte was received
on either the controller or deck port. The time listed is relative to
establishing a connection to the BusAlyzer and is displayed in
microseconds. Currently, the BusAlyzer timestamps received
bytes with a resolution of 100 microseconds.
19

20
Cont and Deck
These two columns display the actual bytes that are received on
either the controller or deck port. These bytes are displayed in
hexadecimal format.
Comment
This column shows the decoded command if it is valid. Currently,
only the Sony P2 protocol as defined in the Protocol of Remote (9-
pin) Connector 2nd Edition Revision 7 is decoded. The decoder in
the BusAlyzer analysis software will attempt to decode commands
even if there are incomplete packets, errors or a checksum
mismatch.
Status Bar
Along the bottom of the window is the status bar. On the left side,
timecode returned from the deck is decoded and displayed here. In
addition to the timecode, source of the timecode, any timecode
flags and the frame rate are displayed here. The BusAlyzer
analysis software currently detects as the color and drop flags.
On the right side of the status bar, the state of the connection to the
BusAlyzer is shown. If the BusAlyzer analysis software is
successfully connected to the BusAlyzer, you will see:
Connected to <BusAlyzer IP address> : <BusAlyzer port>
In the preceding screen shot, you will see:
Connected to 192.168.254.114:23
In the middle of the status bar, you can see whether the ACK
messages from the deck are displayed or hidden. NAKs are always
shown. You can choose to hide or show ACK messages by
clicking on the ACK button on the top of the window.
