Powerline Communications Modem Highspeed PLC-UART-HS

**Replacement: **None. We no longer sell this product and do not have a direct replacement. This page is for reference only.

This is a transceiver module designed to send and receive serial data over AC or DC power lines. This version of the PLC-UART allows for throughput of up to 5Mbps!

On the PLC-UART motherboard there are two 10-pin headers into which an RS-232, RS-485 or USB daughterboard (see related products below) can be inserted. These headers are also pin-compatible with all of our XBee modules, so the PLC-UART can become a powerline communication to Zigbee bridge.

The PLC-UART-HS requires an external 5VDC supply for operation. Communication line voltage can be 230VAC@50Hz, 110VAC@60Hz or 0-400VDC.

These units have the distinct advantage over protocols like X10. The PLC-UART communicates bidirectionally and at up to 19200bps. Not only can you tell the blender to turn on, but you can query the remote device and get data from it (you can't query with X10).

LinkSprite modules have a built-in packet-level repeater function. This feature can greatly extend the coverage of the powerline communication.

LinkSprite modules have both physical and logical addresses. In a network, both physical and logic addresses can be used to address different nodes in the network.

    Looking for suggestions on how to talk to the Powerline Communications Modem Highspeed PLC-UART-HS SEN-09359 via Arduino software based serial port (or I2C). Am using Arduino Duemilanove UART for the IDE.
    PLC-UART-HS powered by Arduino. Arduino powered by a 9volt DC 650ma supply.
    On the PLC-UART-HS interface header I have:
    J6_1(GD) Arduino GND
    J6_2(TX) -> direct connection to Arduino D2 serial RX at 9600
    J6_3(RX) <- 3.3 resistor voltage divider <- Arduino D3 serial TX at 9600 (D3 - 9.2Kohm - J6_3(RX) - 19.4Kohm - GND)
    Sending three "+" characters from Arduino and then immediately watching for incoming data. Nothing comes back.
    Is there a suggested wiring connection scheme between this and the Arduino that might give me a better chance of success?
    Use RS485 interface board UART to RS485 Interface Card SEN-09083? Suggested wiring?
    Use SC16IS750 I2C/SPI-to-UART IC BOB-09745? As a plus it can buffer data from PLC-UART-HS. Wiring from BOB-09745 to the PLC-UART-HS?
    Logic Level Converter BOB-08745? To replace the resistor network I am using.
    Even open to using a different powerline board. Suggestions? Thanks.
