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

4

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: http://www.jlcooper.com

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.

5

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.

6

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

7

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

8

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:

• JB1 – jumper must be in the 2Port position

• JB2 – jumper must be in the 2Port position

• JB3 – jumper must be in the 2Port position

Additionally, one unit must be configured as the Client and the other configured as the Server. To do that,

In the Client,

• JB4 – jumper must be in the Client position

In the Server,

• JB4 – jumper must be in the Server position

U6 and U10 can be configured for the desired operation. That is, if the port is intended to connect to a controller or host, the IC must be in the ‘Ctlr’ position. Conversely, if the port is intended to connect to a deck or slave device, the IC must be in the ‘Mach’ 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, a short tap will suffice.

2. Entering the BusAlyzers IP address in your web browser.

The configuration web page is at: http://192.168.254.112/ .

Please note that this differs from the normal operational IP address.

Note: The Configuration Web Page is ALWAYS at 192.168.254.112 regardless of the normal operational IP address as shown on the

Configuration Web Page.

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.

• 128MB RAM

• Windows 2000 or later

• Ethernet interface

To install the BusAlyzer analysis software, insert the BusAlyzer installation CD into your CD or DVD drive. Open the CD or DVD driver and click on “setup.exe”. Alternately, you can find the latest software on the JLCooper support site, download it to your computer, and install it.

14

Using the BusAlyzer

LED indicators

The BusAlyzer has seven LEDs on the top panel to indicate various operating conditions of the BusAlyzer.

Ethernet

Starting with the Ethernet indicators, there are three LEDs.

Link

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 four LEDs dedicated to serial signals.

Port A IN / Port B 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.

Port A OUT / Port B 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.

15

Setting up the BusAlyzer analysis software

To use the BusAlyzer, power up the BusAlyzer, controller and deck. Next, launch the BusAlyzer analysis software.

After you launch the program, the following window will appear:

BusAlyzer Analysis Software

16

After launching the BusAlyzer analysis software, it is a good idea to configure the software to correctly communicate with the

BusAlyzer. That can be accomplished by clicking the “Settings” button. The following window will pop up:

Specify the BusAlyzer IP address and port in the IP Address and

Port boxes.

Select the protocol that the controller is using.

17

Using the BusAlyzer analysis software

Now that you have configured the BusAlyzer analysis software, click on the “Capture” button.

A window will open indicating the number of packets received.

When you are finished, click on the “Stop” button. The software will then decode and display all the received data from the controller and deck. A typical screen shot will look like this:

18

In the window, you will notice the exchange of data between the controller and the deck. The far left column is the event number followed by the timestamp, the port the command came from, the packet data and the decoded command.

Event

The BusAlyzer numbers each complete command and response in the order it was received and displays the number in this column.

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 milliseconds. Currently, the BusAlyzer timestamps received bytes with a resolution of 100 microseconds.

ID

This column indicates which port the data was received on.

Packet Data

This column displays 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 (9pin) Connector 2 nd Edition 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.

Packet#

This column indicates in which Ethernet packet the command was received.

19

BusAlyzer Software Functions

Capture

This button initiates an Ethernet connection to the BusAlyzer and begins the process of capturing data between the Controller and the deck.

Clear

This button clears all data in the list box.

Save Log

This button allows the BusAlyzer to save all the displayed data to a text file for later analysis.

Set Up

This button causes the set up dialog box to open so the IP settings can be changed.

20

Viewing Command and Response Data

The BusAlyzer Software allows you to view the received commands and responses in two different ways: Packet View and

Byte View. Packet View allows you to analyze a large amount of data quickly. Byte View allows you to see the relationship between the actual bytes, which is helpful in finding overlapping or corrupt messages.

Packet View

Clicking on the “Packet View” button will cause the software to display an entire command on a single line as shown in the screen shot on the following page. You will notice that there is an additional labeled “ID”. This indicates which serial port the packet came from.

21

Byte View

Clicking on the “Byte View” button will cause the software to display each byte on a line. There is a column for bytes received on the Controller port and a column for bytes received on the Deck port.

22

Analysis using Packet Filtering

The usefulness of the BusAlyzer is enhanced by the filtering functionality of the BusAlyzer Software. By definition, the controller queries the deck for time and status quite often. Many times, we are not interested in these messages. Using the filters in the BusAlyzer Software, we can filter out unneeded Time Sense,

Time Return, Status Sense, Status Return and Acknowledge messages.

Time Sense / Time Return / Status Sense / Status

Return

These four buttons are very useful. They allow you to filter out frequently occurring status and return messages. Without them, you must filter many background messages that are not related to your analysis yourself. Clicking the Time Sense, Time Return,

Status Sense and Status Return buttons instruct the BusAlyzer analysis software to filter those messages from the list box.

The sense and return filtering works in both Packet View and Byte

View.

Supported Time Sense messages begin with 61 0C.

Supported Time Return messages begin with 74 00, 74 01, 74 04,

78 04, 74 05, 74 06, 78 06, 74 07 70 0D, 74 14 78 14, 74 16 and 78

16.

Supported Status Sense messages begin with 61 20.

Supported Status Return messages begin with 7x 20.

23

Ack

When a controller sends command blocks to a deck, the deck must always acknowledge the command with an ACK message. Most of the time however, these ACK messages are unnecessary for our analysis and only add to the amount of data we must sift through.

Clicking the ACK button will instruct the BusAlyzer analysis software to hide ACK messages from the deck. Clicking the button again will cause the BusAlyzer analysis software to show the ACK messages. This is helpful to increase the number of useful packets that can be seen on the screen at once.

NAK messages are always shown regardless of this setting.

ACK messages are defined as 10 01 11.

NAK messages begin with 11 12.

24

Technical Reference

Ethernet Interface

The Ethernet Interface is intended for operation with a host computer. It provides the advantages of a standard interface, long cable runs, use over private/public/wired/wireless networks, the ability of being shared among computers and the ability to work with any platform that supports TCP/IP.

The Ethernet interface in the BusAlyzer is a standard auto switching 10baseT/100baseTX, twisted pair interface with an RJ-

45 connector. Use a straight through cable to connect the

BusAlyzer to an Ethernet hub or switch. Use a crossover cable to connect the BusAlyzer directly to a host computer.

Serial Port Interface

The serial ports on the BusAlyzer are intended to connect to either a Controller or a Machine. Each serial port can be independently configured to connect to a Controller or a Machine. From the factory, the BusAlyzer is configured to connect to a controller on

Port A and a machine on Port B.

The pinout of the serial ports is listed in the table below.

GPI Input

Both Port A and Port B have a General Purpose Interface input.

This can be used to sense external signals such as tallies and alarms. This pin is a CMOS input. The input signal must be limited to between 0 and 5 volts referenced to ground. This input is pulled up to +5 volts with an internal pullup resistor. This makes it compatible with dry relay contacts, optoisolators and open collector outputs.

A change in the state of this pin will be indicated in the list box on the BusAlyzer analysis software.

Power

The BusAlyzer requires a 9-12 volt DC power supply capable of delivering at the minimum, 0.5 amps. The unit comes with a power supply (JLCooper part number PSDC117). If you need a power supply specific to your location, please contact your local distributor or JLCooper Electronics.

Warning: using a power supply other than, the unit specified could result in damage to the BusAlyzer and/or other equipment, which is not covered by the JLCooper Factory Warranty.

27

Troubleshooting

If for some reason the BusAlyzer does not give you the expected results, take a moment to do some investigating. The most important concept is that you have your BusAlyzer connected properly as outlined in Installation and Use . Take a moment to double check your setup.

A common problem is forgetting to turn the power switch on or turning the unit on after the software application has launched.

In addition, the JLCooper website ( www.jlcooper.com

) will contain current information on drivers, applications and troubleshooting.
