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.
Installation
Unpacking
When you receive your BusAlyzer, you should receive the
following items:
• BusAlyzer
• This Users Manual
• 9 volt DC power supply
• Installation CD
Please take a moment to register your product at:

This will allow us to notify you of important updates and changes
to software or features.
Setup
The BusAlyzers compact design makes it easy to locate wherever
you need it. The BusAlyzer must be setup up in a location that
does not experience vibration, excessive humidity, dust or
temperature extremes.
The BusAlyzer can be mounted in any orientation.
Connecting the BusAlyzer
Connecting the BusAlyzer is quite straightforward. The
BusAlyzer typically connects between a deck and a controller as
shown in the following diagram.
1. Connect the controller to Port A on the BusAlyzer.
2. Connect the deck to Port B on the BusAlyzer.
3. Connect the BusAlyzer to the Ethernet network
4. Connect the included power supply to the BusAlyzer.

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

for Remote data capture mode.
