Figure 2 shows the Multi-Cal-Slave kit. Each Multi-Cal-Slave kit enables you to expand the system by

eight channels. For example, a Multi-Cal-Master kit and one Multi-Cal-Slave kit combine to form a

16-channel system. Seven Multi-Cal-Slave boards and a single Multi-Cal-Master combine to form a

64-channel system.

Figure 2. Multi-Cal-Slave Kit

The Multi-Cal-Slave kit contains these items:

•

Multi-Cal-Slave PCB: The slave board adds eight measurement channels to the system. The slave

board is almost identical to the master board. The primary difference between the master and the slave

is that the master connects to the USB DAQ Platform and the slave connects to the master via a

ribbon cable, as shown in Figure 2.

•

Slave Ribbon cable: The Slave Ribbon cable connects all the signals and power from the master to

the slave. Note that power is distributed across several wires to minimize loss.

Figure 3 shows the Multi-Cal-Interface PCA card. The Multi-Cal-Interface can be used to connect the

sensor modules to the system. The Multi-Cal-Test boards can also be connected to this board. The

Multi-Cal-Interface board connects to the master or slave via the Multi-Cal-Interface cable on the 37-pin

DSUB connectors.
