Expanding the System Size
Figure 28 shows the jumpers on the Multi-Cal-Slave board that identify the board location. The jumpers on
each slave board must be in a unique position. For the first slave board connected, set the jumpers in the
Slave1a and Slave1b position. As you add additional boards, increment the jumper position. For example,
on the second board connected, use the Slave2a and Slave2b position.
Place jumpers on Slave
in the Slave1a and Slave1b
positions

The final step to expanding the system is to connect the interface-cables from the slave to an interface
board. Figure 29 shows the complete system connection for a 16-channel system (that is, one master and
one slave).
