Use a straight-through Ethernet cable to connect the master to slave peripheral cards, unless
you are using a device such as the OP7200 that could be used either as a master or a slave. In
this case you would use a crossover cable to connect an OP7200 that is being used as a slave.
Distances between a master unit and peripheral cards can be up to 10 m or 33 ft.
