Figure 7-2 Difference between Standard Mode and Initiator/External
MIX Mode
Figure 7-3 shows an example of using TrueCopy or Universal Replicator with
remote command device. The System 1 functions as MCU of TrueCopy or
Universal Replicator, and at the same time it functions as the local storage
system of the remote command device. the System 2 functions as RCU of
TrueCopy or Universal Replicator, and at the same time it functions as the
external storage system of the remote command device. In this case, the
setting of TrueCopy pair or Universal Replicator pair and setting of the remote
command device are both made using the port of the Initiator/External MIX
mode. As this example shows, you only need to connect one cable to one of
the ports that are set to the Initiator/External MIX mode, this means that you
do not need to connect cables to each port of different port attributes.
