PLA200
PowerLine Communication
May 10, 2004
PLA200 Powerline adapters plug into an electrical
outlet to convert the power system into a LAN or
WAN network.
The PLA200 adaptor creates a smart access
point providing Ethernet access at speeds of up
to 14 Mbps with an automatic repeater function,
and offers advanced administration features and
greater security.
PLRP Automatic Repeater Mode
(PowerLine Routing Protocol)
Oxance has developed a powerful routing algorithm
specically for powerline communications, which
enables the PLA200 to act in automatic repeater
mode in transmit and/or receive, guaranteeing
optimal bandwidth and increasing the coverage
of your powerline network.
Advanced Administrative Functions
Managing your powerline network is easy with
the PLA200, which includes an HTTP server,
making the conguration interface compatible
with all operating systems.
An SNMP V1, V2c and V3 agent with trap control
ensures
compatibility
administrators.
A Syslog daemon logs system events. An integrated
network performance utility displays the powerline
network performance in real time.
Upgradable rmware in the PLA200 can be
updated via the network.
Enhanced Security Level
MAC address ltering means you can eliminate
the Network Neighbourhood on Windows PCs,
enable or disable PLA200 use or conguration,
control network access, and control the bandwidth
allocated to users.
The AES 128 bit encryption protocol guarantees
the integrity and security of data transmissions.
Optionally, it may be used with the DES 56 bit
security protocol included in the HomePlug
1.0.1 protocol.
The PLA200 offers two-layer data security without
sacricing performance.

Please take the following precautions : Read and follow all of the safety instructions and warnings appearing on the device and in this manual. Your electrical system must be equipped with a circuit breaker to prevent short circuits.

  • Page 5: The Powerline Communication Network

    On the three-phase network, the high frequency coupling of the phases in the input cable may be sufficient to allow PLCnet TM units plugged into different phases to communicate with each other. For systems with long wiring or a band-stop filter, we recommend installing an Oxance capacitive coupler (CPL3PH) for better performance.

  • Page 6: The Most Common Architectures

    (1) Your DSL internet access is limited to one computer or located in just one room : Connect a PLA200 to the Hub/Switch where the router is plugged in and you have instant, simultaneous internet access for all the computers in your company.

    4.2 Automatic Repeater (improving distances) Example of the relay feature : PLA200s A and C are too far apart to be able to communi- cate with each other. PLA200 B is automatically used as a relay to create a connection between A and C.

  • Page 11: Managing Bandwidth

    For statistics or invoicing purposes, you can count the number of bytes sent and re- ceived by the PLA200s. The counters are saved to flash memory and can be reset only by the administrator. Just plugging in or unplugging the PLA200 does not reset the counters.

    4 THE ADVANCED FEATURES OF THE PLA200 4.8 Configuration by HTTP Server The PLA200s can be fully administered via a Web interface. No external software is needed (no need to install software on your computer), you already have the software you need to administer the system a web browser such as Internet Explorer 6 or Mozilla 1_4.

  • Page 15: Features And Recommendations

    The PLA200 can relay the signal and transmit over long distances (repeater function) only if each PLA200 is no farther than 200 meters away from the next closest PLA200. The repeater function is automatic and does not required any special configura- tion.

  • Page 16: Installing The Pla200

    Advanced configuration (security, filtering, analysis) is done using a common web browser. Plug in the PLA Ethernet adaptor to an electrical outlet. Connect the Ethernet cable to the PLA200 and to the Ethernet interface on your device or to your Ethernet Hub/Switch.

    The quality chart shows a global view of the network quality. It is read line by line, from left to right, and displays a value and colour for each PLA200 pair analysed. Quality can be displayed in 4 modes : raw mode (powerline estimate between 1 and 14 Mbps by default) tcp mode (TCP estimate between 1 and 5.8 Mbps)
  • Page 25 PLA4 as a relay. PLA3 cannot communicate directly with PLA2 and PLA4 (too far apart), so it must use a relay (PLA1). This interpretation can be checked by viewing the routing table for each PLA200 "PLA Selection - route".
  • Page 26 8 GRAPHIC CONFIGURATION Interpreting a chart with asymmetry By the very nature of the power system, the communication quality between two powerline devices is asymmetrical in transmit and receive. Identical or similar quality rates indicate optimum quality, whereas a large discrepancy indicates electrical interference.

Changing the encryption key: By changing the encryption key, (PLC password) you automatically change the encryption keys of all the devices visible on the powerline network.
  • Page 29 This is the password used to connect to the PLA’s HTTP administration server. It is also used as an authentication and encryption key for SNMPv3 administration requests. The user name to setup the PLA is "admin" (lower case) and password is “oxance.com”.
