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.
