, the built -i n di splay and keypad supports the
remote mode
, the moni tor is
controlled by a hos t comput er vi a an RS-232 serial communic ations port.
For remote mode operation, MCC offers an optional Windows-based
Bus / SMBus Analyzer
software (#SMB-SW) to provi de remote cont rol of

the monit or from a PC. This software allows bus message data t o be
captured, logged, filtered, displayed, and analyzed using one of several
built-in protocol parsers, i ncluding the dis pl ay of Smart Battery Syst em
(
SBS
) mess ages in engineering units .
In addition to MCC’s standard soft ware, a c ustomer may also develop
custom software to meet special processing requirements. Custom
software can cont rol , collect , and upl oad bus mess age data to a host
system. This provides a powerful tool for integrati ng the monitor into an
automatic manufacturing-test environment. Remote cont rol i s
accom pl i shed via a series of ASCII t ext commands . A description of the
monitor comm and set is provided in the Applicati on Program Interface
section of this m anual .

The complete I
C Bus / SMBus Monitor package c onsists of a hand-held
unit, connecting clip-l ead and i nterface cables, power supply, and optional
W i ndows-bas ed analyzer software.

Set-Up
Connecting a Power Source
The I2C 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 i n the
position. Thi s power source allows the unit t o operate stand-alone, or
ON
when another power source is unavailable.
External Power
W hen the power switch is in the
EXT
ernal position, the unit can be
powered from:
1. The BUS +5V (V) Input line.
2. A regulated +5V wall power supply (Digi -Key #T309-ND or CUI/Stack #
DPR050030-P6) through the external power jack (
~ ~ ~ ~
CA UTION
~ ~ ~ ~
+5V
).
Powering the monit or from its +5V external power jack applies power to
the BUS +5V (V ) l i ne. The BUS V line shoul d onl y be connected to the
system under test if : a) You are powering the monit or from the target
system; or, b) You are powering the target system from the monitor.
NOT CONNECT BOTH THE WALL POWER AND TARGET POWER
SUPPLIES TOGETHER.

Connecting the External Trigger
The monitor provi des External Triggering for Trace s ynchronization with
external events. Trace synchronization allows bus traffic t o be collected
immediately before or af t er an el ectronic event.
A High-to-Low transit i on on t he External Trigger port can be used t o start
a PRE-TRIG trac e, or stop a POST-TRI G t race. See the Trace Mode
section of this guide fo r t race synchronizati on det ai l s.
Connecting the Serial Cable (optional)
The Serial Cable provides the connection bet ween the monitor and an
optional Host system. On monitor, the Serial Cable connec ts to the
modular RJ-45 connector m arker
connects to a standard RS-232 serial communicati ons port. Both DB -25
