12.2.4 Ethernet and serial
To connect Ethernet and non-Ethernet units in a dual Ethernet-serial system
In this dual system the laptop/PC is connected to the Ethernet units via Ethernet and non-Ethernet units
via serial/USB. In the Ethernet system, connect the Ethernet units using Ethernet cable, using one of
the options in Section 11.2. Connect the first Ethernet unit to the PC via Ethernet using one of the
options in Section 11.3. In the serial system, connect the non-Ethernet units together in a daisy chain
configuration and connect the first of these units to the PC using any of the methods shown in
Section 12.2.1.
In this configuration the Ethernet system provides fast operation, while the serial provides slow
operation.
Note
In this configuration the Ethernet and serial networks are entirely separate, as they are
connected to the PC via different ports. This allows the networks to be running different
protocols. However, to do this the PC will need to be running two RCS programs of the
equivalent protocols.
