Chapter 1: Introduction  
Overview  
The Planet 85M Powerline to Ethernet Bridge with 4-Port Switch, PL-420,  
operates on the HomePlug Powerline Specification 1.0.1 standard for providing  
up to 85Mbps bandwidth over home AC wiring. Since the home power lines are  
the most pervasive medium in households with multiple outlets in every room, the  
PL-420 allows multiple home desktops and notebooks to be networked to share  
Internet connections, printers, files, and play games without any additional wiring.  
The installation of the 85M Powerline Ethernet Switch only requires that a  
10/100Mbps Network Adapter is installed on the computer. This makes the PL-  
420 compatible with any device including Mac, Windows, and Unix machines.  
For security reason, the HomePlug devices are equipped with 56-Bit DES  
encryption. The private home power grid plus encryption makes HomePlug  
significantly more secure than competing technologies. The PL-420 is the best  
solution for No-New-Wires home networking. With easy Plug and Play installation,  
no need for new wires.

Chapter 3: Configuration  
Overview  
The PL-420 uses 56-Bit DES encryption to block outside access. The key is set  
by using the Configuration Utility on the CD. By default, the protection is enabled,  
however, it is recommended to change the default network password. All your  
powerline devices must use the same network password in order to be  
connected together.  
Diagnose Powerline network  
Part 1: Diagnose a Local Powerline device  
Double click the PowerPacket Utility icon on your desktop, and utility screen will  
show up as below:  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
The Main tab shows the powerline units that are connected to the current  
computer and other powerline devices on the home network, and it will  
also display Mac Address of each device.  
**Note** If you do not see ANY unit in the device status but the powerline  
device does exist, try to press “Scan” button or unplug all devices and  
plug them back. Meanwhile, please make sure the cable is the right type  
and working correctly. If all seems to be correct, and you still receive  
nothing in the Device window, try rebooting your computer.  
Part 2: Diagnose a Network Powerline device  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
The Main tab shows all the other powerline units on your home network. It  
will represent them by MAC Address, and will also show the available  
bandwidth to each unit (Units farther away from another powerline device  
might have a lower Data Rate). If you add or remove units from your  
home network, click the “Scan” button to re-scan the network, and refresh  
with any changes.  
**Note** Only units with the same Network Password will be shown,  
(Password case sensitive).  
**Note** If a unit shows MAC Address of all 0’s, this unit might not have a  
solid connection, or might not connect at all.  
**Note** If there are units in the home network, but nothing displays in this  
Network scan, try to unplug all devices, and plug them back (Only do this  
with the units that you do not view in the network screen, you don’t have to  
do this with all units.)  
If the problem persists, try to move the unit closer to this current unit  
(adjacent plugs on the same wall socket is most preferable). If the  
problem still persists and that unit is still not shown on the network, then  
the unit might be defective. Please contact technical support. Otherwise if  
you view the unit working, distance might be the only issue.

Setting Up Security on a Local Powerline device  
The Privacy tab will allow you to change the Network Password to the  
unit that is currently connected to this computer. This network password  
encrypts all data that is sent from this unit using 56-Bit data encryption  
standard (DES).  
**Note** Every unit on your home network MUST have the same Network  
Password for connectivity to be established throughout your home. The  
default network password is “HomePlug”.

Setting Up Security on a Network Powerline device  
The Privacy Tab will allow users to use one primary computer to control  
the Network Password of all units on the home network.  
You will have to go back to the Main Tab first then find the DEK (Device  
Encryption Key) Key located on the bottom of each device. Click Enter  
Password and enter this Key into the Device Password area. Click OK.  
This Device Key will then appear in the bottom of window. Add all DEK  
Keys for each unit in your house. You can go back to the Main Tab then  
change the Private Network Name remotely from one computer. This will  
allow you to change the Private Network Name from one computer,  
instead of changing the password individually.

Appendix A: Troubleshooting  
Frequently Asked Questions  
1. What’s the speed of the PL-420 operating over a standard home power  
line network?  
The PL-420 operates up to 85 Mbps bandwidth over a standard home power line  
network.  
2. What’s the Estimated Range of the PL-420?  
Approximately 300 meters in wall power lines (one household).  
3. Does PL-420 work in any home?  
The PL-420 should work with copper wiring in any home. Since some of the older  
houses built before 1950 might have older wiring, it may not work in this instance.  
4. Does PL-420 signal pass through circuit breakers?  
Yes, this device signal will have no problem pass through circuit breakers but not  
through power transformers.  
5. Does PL-420 work with AC input 100 – 240V?  
Yes, this device works with AC input 100 – 240V.  
6. Does PL-420 cause any interference with other home networking devices?  
No, this device operates in a different frequency band than other power line  
control devices and can co-exist with technologies as X-10, CEBus, and  
LONworks.  
7. Can my neighbor receive my PL-420 signal?  
It is possible for your neighbor receive your PL-420 signal between two adjacent  
homes. To prevent this happen, please enable the 56-bit DES security  
encryption on your device. To do that, you must run the HomePlug Configuration  
Utility on each Homeplug device in your power line network. This will only allow  
computers with the same security password to be able to receive information.  
8. How do I find out what’s my current speed and my signal strength of my  
HomePlug device?  
20  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Run the HomePlug Configuration Utility, it will show your current speed and your  
signal strength.  
9. One of the PL-420’s LED doesn’t light up after I plug the HomePlug  
directly into a wall outlet?  
Test that wall outlet with other electric devices first, make sure that wall outlet is  
working properly. Then, try to plug your HomePlug device again. If the same  
problem happens again, plug both HomePlug units into adjacent sockets, and  
check if the lights light up. If you are still having problems, please contact your  
reseller.  
10. The Ethernet LED doesn’t light up on my PL-420?  
In most cases, if the Ethernet LED doesn’t light on your device, it is because the  
Ethernet port doesn’t detect a LAN connection. Check your Ethernet adapter on  
your computer, and make sure its enable and working properly. Also, check your  
Ethernet cable; make sure you use the right type. It’s plugged in correctly and it’s  
worked properly.  
11. I can’t connect to Internet and other computers on my power line  
network?  
(1) Check your IP address and TCP/IP protocol are set up properly for all the  
computers on your power line network. Also, try to check your gateway and ping  
the gateway.  
(2) If HomePlug Configuration Utility detects other HomePlug devices on your  
power line network. Try to plug in both HomePlug units into adjacent sockets and  
see if the lights light up. If you are still having a problem, please contact your  
reseller.  
12. How many HomePlug devices do I need to setup a powerline network?  
You need two or more HomePlug devices to setup a powerline network.  
13. In order to making the PL-420 working properly, do I have to install the  
HomePlug Configuration Utility on every single computer who has the  
HomePlug device plug into it?  
No, the HomePlug Configuration Utility is a utility to diagnose or setup encryption  
for HomePlug device. Due to PL-420 is a fully plug and play device, no driver  
require to install. In other words, the HomePlug Configuration utility is not a  
requirement to install on your computer. You can install the utility, setup the  
encryption, and delete it from your computer. Your PL-420 will still work properly.
