5. Before returning the serviced equipment to the customer, make the following insulation resistance test to prevent a shock haz-
ard.
2Warning
2.1. About Lead Free Solder (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con-
tains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.
Caution
• PbF solder has a melting point that is 50°~ 70°F, ( 3 0 °~ 40°C) higher than Pb solder. Please use a soldering iron with tempera-
ture control and adjust it to 700°± 20°F, (370°± 10°C). In case of using high temperature soldering iron, please be careful not to
heat too long.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, ( 6 0 0°C).
• If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and
be sure that any remaining is melted prior to applying the Pb solder.
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the
opposite side (See figure, below).
2.1.1. Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufacturer’s
specific instructions for the melting points of their products and any precautions for using their product with other materials. The fol-
lowing lead free (PbF) solder wire gauge are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2.2. For Service Technician
ICs and LSIs are vulnerable to static electricity.
When replacing, the following precautions will help to prevent recurring malfunctions.
1. Cover the plastic parts with aluminum foil.
2. Use a conductive mat on the work-table.
3. Do not grasp IC or LSI pins with bare fingers.
2.3. INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Measure the resistance value with ohmmeter between the jumpered AC plug and Exposed Metal (LAN Connector).
Note:
Some exposed parts may be isolated from the chassis by design. These will read infinity.
3. If the measurement is outside the specified limits, there is a possibility of shock hazard. The equipment should be repaired
and rechecked before it is returned to the customer.
2.4. CAUTION
The power socket wall outlet should be located near this equipment and be easily accessible.

5 Technical Descriptions
This power supply board uses the switching regulator method.
[Input Circuit]
The input current goes into the input rectifier circuit through both the fuse and the filter circuit. The filter circuit decreases the
noise voltage and the noise electric field strength.
[Rectifier Circuit]
The input current is rectified by D801 and D802 and charges C804 to make DC voltage. Then it supplies power to the converter
circuit.
[Converter & Control Circuit]
The following is an overview of how the power supply unit is controlled.
The control method of this power supply unit is pulse width modulation as Semi-Resonance Ringing Choke Converter.
When IC801 is ON, the energy is charged in the switching transformer primary coil according to Vin. When IC801 is OFF, the
energy is output from the secondary transfer as follows. Then the power is supplied to the Load. When IC801 is ON, power is
not output from the secondary side.
The output voltage is feed back in the IC801 according to the error detect circuit.
When Vin increase, IC801’s on duty Ratio decrease. As a result, Charge of energy to the switching transformer primary coil
becomes the same as Low Vin, and Vout is kept constant.
When Iout increase, IC801’s on duty Ratio increase. As a result, Charge of energy to the switching transformer primary coil
becomes the same as Low Vin, and Vout is kept constant.
C806 (Resonance Capacitor) is connect to IC801’s #5pin-#7pin, rapid standup of flyback voltage is controlled.(Semi-Resonance
Ringing choke converter operation)
[Surge Absorber Circuit]
This circuit is for absorbing surge voltage generated by the transformer.
[Error detect Circuit]
The control circuit amplifies the output with increased voltage detected in the error detecting circuit.
In this power supply, the duty ratio is defined by changing the ON period of IC801.
This is shown as follows.
When the output voltage of the +10.5V circuit increases, the current of the photo coupler PC801 increases, the pulse width of
IC801 becomes narrower and the ON period of IC801 becomes shorter.

9
BL-PA100A/BL-PA100KTA
[Over Current Limiter (O.C.L)]
The highest drain current (IC801) is limited by a internal circuit of IC801. The +10.5V output is limited by this circuit.
[Over Voltage Protection Circuit (O.V.P)]
If the +10.5V output increases because the error detecting circuit is broken, The internal circuit of IC801 will recognize this sig-
nal and output becomes 0V.
[Thermal Shutdown Circuit]
IC801 become shutdown when internal temperature becomes 130 degrees C (typ).
[PLC Coupling Circuit]
This circuit superimposes a PLC signal on AC voltage from a MAIN board.
[Async Circuit]
This circuit outputs the rectangle waveform which synchronized with AC frequency.

7 Operation Instructions
7.1. How does it work?
Each HD-PLC adaptor has an AC cord that plugs into a wall outlet. This connection not only powers the adaptor, but also allows
the adaptor to send data to and from the other adaptors in your home using your existing electrical wiring. Each adaptor also
has a LAN jack, which connects each adaptor to your broadband router, hub, computer, network printer, network camera, etc.
Once your adaptors are registered, simply plug them into the wall outlets around your home. (The included adaptors are already
registered.) Finally, connect the master adaptor to your broadband internet router or modem, and then connect the other adap-
tors to your network devices (computers, network printers, network cameras, etc.). When you’re finished, each network device
will be able to access the internet as well as each other.
Master and terminal adaptors
Before using your adaptors, it is important to understand the concept of a “master” adaptor and a “terminal” adaptor.
An HD-PLC network contains at least 2 adaptors. One (and only one) adaptor must be configured as the master. All other adap-
tors are configured as terminals. (A maximum of 15 terminals per network is recommended.) An adaptor is configured as either
a master or a terminal during registration. For simplicity, we recommend configuring the adaptor that is directly connected to one
of your router’s LAN ports as the master.

7.2. Testing a terminal’s network speed
Once you have connected the adaptors where you plan to use them, use the procedure below to test the speed of each termi-
nal’s network connection to the master. Make sure that the terminal has already been registered to a master.
1. Press and hold the terminal’s SETUP button for about 1 second.
• The indicators on the terminal light one at a time in succession for a few seconds.
2. The indicators light for a few seconds. This indicates the network speed test result.
3. Refer to the chart below to determine the network speed.
4. If you are not satisfied with the speed test result, connect the terminal to a different wall outlet and repeat the test.
Note
• At least one indicator (“Good” network speed) must be lit in order to use the terminal.
• If you are not satisfied with the speed test result and have tried connecting the terminal to different wall outlets, refer to the trou-
bleshooting section.
• If the electrical conditions in your home changes after performing the speed test, network speed may also change.
Once you are satisfied with the termina’s speed test result, you are ready to connect each adaptor to a network device (broadband
router, hub, computer, network printer, network camera, etc.).

8.2.2. Power Supply PCB Check Flow Chart
Check the following parts first: F801, ZNR801, IC801, D801, D802, Q801, T802 and IC802.
This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding
voltage test, intentional short circuit test, etc.
Caution:
If you find a opened fuse in the unit, do not turn on the power until you locate and repair the faulty parts (except for the fuse);
otherwise the fuse will open again and you cannot pinpoint the faulty point.
In most cases, the symptom is that nothing is output. It is more likely that the fault is in the primary side rather than the second-
ary side. Check the primary side first.
