Installation Setup
Congratulations on your purchase of the PL7070-COM PLC/RS-485 Adapter.
The PL7070-COM adapter allows you to transmit RS-485 data between two points via the
existing electrical wiring by simply plugging the PL7070-COM directly into an electrical
outlet. The PL7070-COM acts as a bridge for the RS-485 signal. This manual describes
how to install your PL7070-COM PLC/RS-485 Adapter.

z Quick Installation Guide
z Warranty and Support Information Card
If any of the parts are incorrect, missing, or damaged, contact the retailer where
you made your purchase. Keep the carton, including the original packing materials, in
case you need to return the unit for repair.
Finding a Suitable Location
Find a suitable location to install your PL7070-COM adapters. If possible, find a location
that has:
• Acceptable temperature and humidity ranges (see the PL7070-COM specifications
on page 9)
• Free of strong electromagnetic field generators (such as motors), vibration dust
and direct exposure to sunlight.
• An electrical outlet for your PL7070-COM adapter that is within the RS-485
distance specs.
6 of 20
Simple Connection (Peer to Peer)
1. Connect one PL7070-COM device to your Solar Inverter with an RS-485 cable
(twisted wire); then plug it into a wall outlet. For the PL7070-COM Pin Out
Wiring Specifications, see page 11.
2. Connect the other PL7070-COM device to your Data logger with an RS-485
cable(twisted wire); then plug it into a wall outlet.
3. Set the Baud Rate on both adapters to the same Baud Rate (speed) as the Solar
Inverter and the Data Logger. You can change the Baud Rate by pressing on the
Baud Rate Key (see page 10 for the location of the Baud Rate Key button). For
additional information on how to use the Baud Rate Key button, see page 13.
4. See Figure-1 below for your reference.
Figure-1 Solar Inverter and Data Logger connection via PL7070-COM PLC adapters.
Congratulations! You have completed the installation of the
PL7070-COM.
NOTE: Do not plug the PL7070-COM adapter into a power strip, UPS
(Uninterruptable Power Supply) or surge protector device. This may prevent the
unit from working properly or degrade the PLC (Powerline communication)
network performance.

Troubleshooting
Following are solutions to a few situations you might encounter. If you do not find a
solution in this chapter, contact Asoka USA Technical Support by phone at (408) 550-
8173 or through email at support@asokatech.com.
Symptom:
I can't connect to anything and there are no lights (LED) activity on my PL7070-COM.
Solution:
• Unplug the device from the electrical outlet in question.
• Locate another available outlet.
• Test the outlet by plugging in an electrical device such as a lamp or radio.
• Plug the PL7070-COM into the working electrical outlet.
• Check to see if the lights (LED) work
• If the above does not work, the device might be defective.
• At this point, please contact Asoka Technical Support for instructions on
returning the device for repair or replacement.
Symptom:
The lights seem to be functioning, however, the solar inverter and data logger do not
communicate (no connection).
Solution:
• Check the Baud rate on both PL7070-COM (front Baud rate LED indicator), the
Baud rate must be the same on both PL7070-COM devices. If the Baud is not the
same, simply press the Baud rate button to change it to the correct speed.

Buttons
The PLC/RS-485 Adapter device has two hardware push buttons:
SECURITY (Network ID) button – All PLC/RS-485 Adapter devices have a default Network
Encryption Key (NEK) set to “HomePlugAV” allowing them to communicate to each other. The
SECURITY button allows you to set a devices to a randomized Network Encryption Key (NEK) for
maximum security. You can then set other devices to the same NEK by using their SECURITY
button. Only units with the same NEK can communicate to each other.
Baud Rate Key button and lights:
1. This button allows you to change the Baud Rate speed to 1200,9600 and 19200. The two
PL7070-com device baud rate should be same.
2. The Baud Rate light will start to flashing if data is passing through the RS-485 Connector.
3. Locking and Unlocking the Baud Rate:
• To lock a specific Baud Rate on the PL7070-COM adapter, simply press the Baud
Rate Key button for about 8 seconds. The correspond led will flash if the time
is reached, meaning that the baud rate is locked. To Unlock the Baud Rate,
press the Baud Rate Key button again for about 8 seconds; then it will unlock,
or powering OFF then ON will unlock the baud rate.
SETTING A RANDOMIZED PLC NETWORK PASSWORD (NEK)
1. Select a PL7070-COM Adapter (Device A) and plug into an AC outlet. The POWER light
indicator should be lit solid green.
a. Press the SECURITY button BRIEFLY (0.5 to 2 seconds) and release. The POWER light
should now be blinking green.
b. IMPORTANT: If the POWER light is not blinking green, repeat Step “a” until the
power light blinks green.
c. This unit is now ready to create a new randomized NEK (Net Encryption Key)
network. This unit will remain in this “adder” mode for about 2 minutes.
2. Select another PL7070-COM Adapter (Device B) and plug into a second outlet.
a. Press the SECURITY button BRIEFLY (0.5 to 2 seconds) and release. The POWER light
should now be blinking green.
b. IMPORTANT: If the power light is not blinking green, repeat Step “a” until the power
light is blinking green.
3. In about 15 seconds the POWER light will change from flashing green to solid green and
the PLC ACT (Power line Communication Activity) light will turn solid green (flashing
green when there is data traffic) indicating they are synchronized with the same NEK.
4. Congratulations, you are done!
