Configuring a DS2 Network
The Spanish manufacturer DS2 is a player on the HomePlug market whose products
are not compatible with HomePlug devices.
A DS2 200-Mbit/s PLC network is locally configured on the device via an HTTP
interface. Therefore, it is identical for Windows and for Linux/FreeBSD.
The DS2 devices can operate in three different network modes:
•
HE: The device is the PLC network master.
•
CPE: The device is the PLC network slave.
•
TDREP: The device is used as the PLC network repeater.
We will illustrate this section with Corinex AV PLC devices based on DS2 Wis-
consin chips. There are two firmware types in these devices: alma and spirit. We
have chosen a device with alma firmware, which offers more functionalities.
Before connecting to the HTTP interface, the PLC device and the configuration
PC must be placed in the same IP addressing plane. Since the default IP address of
Corinex AV PLC devices is 10.10.1.69, the IP address of the configuration PC must
be configured in the same addressing plane, for example, 10.10.1.10.
Figure 9.32 illustrates the various addressing planes that will coexist on the elec-
trical network.
Once you are connected to the homepage, enter the default password (paterna)
to open the configuration pages as illustrated in Figure 9.33.
The first configuration page offers an overview of the main parameters of a DS2
PLC device (see Figure 9.34), in particular the following ones:
•
IP address of the PLC device;
•
MAC network mode (HE, CPE, TDREP) of the PLC device;
•
PLC physical link mode;
•
Multicast groups at the IP layer level;
•
Key (or password) used for securing the PLC network;
•
Priorities of some data flows between PLC devices.
These parameters can be configured separately then validated and written into
the computer’s nonvolatile memory. The modifications made to the overall configu-
ration are taken into account by rebooting the device.
The IP address, the subnet mask, and the default gateway of the device can be
configured by clicking on “Change configuration” below “Default Gateway IP
Address.” The configuration page illustrated in Figure 9.35 is then displayed.
In the example of Figure 9.36, the addresses of the PLC1, PLC2, and PLC3
devices are 10.10.1.1, 10.10.1.2, and 10.10.1.3, respectively, and the subnet mask is
