SM (SMBus) Control
Paddle card Settings
The FS2343 probe is designed so that AMB/LAI device control can be either from the
16900 logic analyzer and the Probe Control application software resident there, or from
another FS2343 probe (slave mode).
This feature is controlled by means of a 6 position switch on the probe paddle card near
the logic analyzer connections.
The factory configuration is for 16900 control of the probe. The settings on the switch
are dependent on the configuration file used. The following picture shows the jumper
and switch configurations on the paddle card.
