Page 12: Set-Up
Set-Up Connecting a Power Source The I C Bus/SMBus Monitor can be powered from either internal or external power sources. Internal Battery Power An internal 9V battery provides unit power when the power switch is in the ON position. This power source allows the unit to operate stand-alone, or when another power source is unavailable. -
Page 13: Connecting The External Trigger
Connecting to an I C Bus / SMBus The unit provides a test clip lead cable for connection to an I C Bus or SMBus under test. On the monitor, the test clip cable connects to the Molex Semicon modular connector marked BUS. Test clips are provided for: Clip ID Signal... - Page 14 When using a Host computer, data terminal, or terminal emulator program to access the monitor via its RS-232 port, communication parameters must be properly set before communicating can begin.

Page 16: Operating Modes
Operating Modes The I C Bus / SMBus Monitor can operate in two modes, stand-alone and remote. In stand-alone mode, the built-in display and keypad supports the capture and display of bus data. In remote mode, the monitor is controlled by a host computer via an RS-232 serial communications port. -
Page 17: Address Select Mode
Address Select Mode Address Select Mode is used to select the bus slave address or addresses the unit will monitor. Address Select Mode is entered by pressing the MONITOR-SELECT or MONITOR-ALL key on the unit’s front panel. The MONITOR-SELECT key is used to specify a single bus slave address to monitor. -
Page 18: Trace Mode
Selecting any other operating mode terminates View Status Mode. Trace Mode In Trace Mode, the unit collects and stores all or selected bus traffic with PRE or POST Trace triggering. Trace Mode is entered by pressing the PRE-TRIG or POST-TRIG key on the unit’s front panel. - Page 19 • Acknowledgments and Negative-Acknowledgments • Transmitted Data in Hex and ASCII • View Data supports forward and reverse scrolling of captured data bytes or messages. View Data key/actions include: Action BYTE-UP - Move Backward one byte. BYTE-DOWN - Move forward one byte. MSG-UP - Move Backward one message.

Page 20: Remote Mode
Selecting any other operating mode terminates View Data Mode. Remote Mode In Remote Mode, the unit is controlled by a Host computer system via its serial port. Bus traffic can be collected or uploaded to the Host system for storage and further analysis. Remote Mode is entered when the unit receives a Serial Command at its serial port. -

Page 29: Application Program Interface
Application Program Interface The Host System Interface provides RS-232 port access to monitor data capture functions. The monitor provides the following Serial Commands to assist in bus traffic collection: 19.2K Baud Select ... 1 57.6K Baud Select . -
Page 30: Baud Rate Select
< > Control keys. Baud Rate Select Syntax: 1 (9200) | 5(7600) Description: The Baud Rate Select command sets the units serial port to 19.2K or 57.6K baud. The unit defaults to 19.2K baud at power-up. Executing a Remote Trace on high volumes of bus traffic at 19.2K baud may cause loss of data on buffer overflows. -
Page 31: Ascii Remote Select
ASCII Remote Select Syntax: A Description: The ASCII Remote Select command configures Remote Trace data to be sent to the serial port in printable ASCII format. At power-up, ASCII Remote is the default transfer mode. When ASCII Remote in enabled, data is transferred in three-character ASCII sets. The first character specifies the data type, and is followed by a two character slave address or data. -

In the above example, a single bus message is uploaded to the Host system in ASCII format during a Remote Trace. - Page 33 4 - Data without Acknowledgment. 5 - Stop. A - 8-bit Slave Address (00...FFH). H - 8-bit Data (00...FFH). NOTE The Binary format is reserved for future MCC product support. Example: B<ENTER> R<ENTER> 150320...323500<CR><LF> where: 1 - Start with Acknowledgment.

Page 34: Cts/Rts Handshaking Command
CTS/RTS Handshaking Command Syntax: C Description: The CTS/RTS Command is used to toggle Clear-to-Send / Request-to-Send Serial Link flow control. The power-up default condition is CTS/RTS Handshaking disabled. When enabled, CTS/RTS Handshaking halts monitor serial port output when the Host RTS line is dis-asserted. This feature is useful in preventing serial link data overflow on the host system. -

Dump Trace Buffer terminates upon exhausting the buffer, or upon receiving an Escape <ESC> character on the serial port. Screen Pause <Ctrl-S> and Screen Resume <Ctrl-Q> are active. Example: D<Enter> In the above example, buffered bus messages are uploaded to the Host system in ASCII format during a Dump Trace Buffer operation. -
Page 36: Remote Trace
Example: E<Enter> Enable Simulation Remote Trace Syntax: R Description: The Remote Trace command places the unit in POST-TRIG Trace Mode, and sends all bus traffic to the serial port. During a Remote Trace, data in temporarily buffered in the unit, then sent to the serial port in the currently selected ASCII or Binary format. -

Appendix A - Solving Problems Solving Problems If you suspect a malfunctioning unit follow the steps described below before contacting MCC for additional assistance. Problem: Unit does not display the sign-on message on the internal LCD display at Power-up. Solution: 1. - Page 40 Problem: Unit does not collect bus traffic in Trace Mode. Solution: 1. Check cable connections at the unit and bus. When using the Test Cable, confirm SCL, SDA, and GND clip leads are connected to appropriate bus lines. 2. Check Selected Address. If a single bus address is specified, only messages directed to that address will be collected.
