3 Expanding the System Size
The Multi-Cal-System can be expanded by adding Multi-Cal-Slave boards. Each Multi-Cal-Slave board
adds eight additional channels. The maximum system size is 64 channels (one master and seven slaves).
The first step in expanding the system size is to remove the 0.25-inch standoffs and replace them with
1.25-inch standoffs; this step is shown in Figure 23.
