Theory of Operation for Multi-Cal-Slave EVM Hardware
2.2
Control Schematics
The detailed theory of operation for the Multi-Cal-Slave does not cover every circuit in the hardware
because the slave and master hardware designs are very similar. This document covers only those
circuits that are unique to the slave board. Refer to the Multi-Cal-Master User Guide (

shows the jumpers and associated circuitry for decoding the slave address (1 through 7). The
output of this decoder will be used to set the I

C™ address on the I

C bus expanders that are used to
control the power-switching circuits on each slave board. Thus, each slave board will have different I

C
addresses for the control circuitry.
