21.1 Network cable connections
A PC can be connected directly to the Ethernet interface of the SPC controller or
via a LAN connection. The tables below show the 2 possible connection
configurations.
If the SPC is connected to an existing network via a hub, then connect a
straight through cable from the hub to the SPC and another from the hub to the
PC.
If the controller is not connected to a network (i.e. a hub or switch is not used),
then a crossover cable should be connected between the SPC controller and
the PC.
Use the straight through cable for connecting the SPC controller to a PC via a hub.
