1Warning
1.1. Battery Caution
Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to following caution:
Disposal or transportation of lithium batteries should be performed by permitted, in accordance with federal, state and local
guidelines.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong
packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate dis-
position. This is a good practice for all types of commercial or industrial waste.
When the lithium battery is exchanged, the clock settings are cleared. In this case, make clock settings again.

1.2. 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.
Caution
• PbF solder has a melting point that is 50°F ~ 70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with tem-
perature control and adjust it to 700°F ± 20°F (370°C ± 10°C).
• Exercise care while using higher temperature soldering irons.:
Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, ( 6 0 0 °C).
• 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).

BB-HCM511A/BB-HCM531A
1.2.1. 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.

4.4. Audio Block
External Microphone Jack (CN505)
Used with the external microphone.
Audio Output (CN504)
Used when connecting a speaker with a built-in amplifier, when the audio is output from a camera.
Microphone Detection (Q501)
When the external microphone plug is not inserted, pins 3 and 2 of the Microphone Jack (CN505) are short-circuited and a base
current is supplied to Q501 through R501, R506 and R505 so that the Q501 goes ON and a collector (MIC_S signal) goes LOW.
Alternatively, when the microphone plug is inserted, pins 3 and 2 of the CN505 become open so that the Q501 goes OFF and
the MIC_S signal goes HIGH. From this signal, the CPU detects the microphone status.
The CPU turns the microphone SW on and off in the PCM Codec (IC501) for the external or the built-in microphone, as appro-
priate.
ALC Amplifier (IC602: For the built-in microphone, IC603: For the external microphone)
Power Supply: 3.3V
Amplifier for Auto Level Control
PCM Codec (IC601)
Power Supply Voltage: 3.3V
Clock Frequency: Contains a built-in PLL function and generates a clock from the BCLK (256 KHz).
Contains an amplifier, LPF, gain adjustment, AD/DA converter, host I/F, PCM serial I/F and speaker output function.
Flow of audio Signal
[Microphone audio]
1. The audio signal input from pin 1 of the built-in microphone connector (CN501) is amplified by the amplifier in the PCM Codec
(IC501) and the ALC (IC502), then input as the built-in microphone to the PCM Codec (IC501) again.
When the level of the input audio signal is more than the specified value, the gain is changed and the output signal level is
kept constant at the ALC (IC502). Audio distortion is controlled when the input is excessive.
2. When the external microphone is attached to the microphone jack (CN505), the audio signal input from pin 2 of the CN505 is
amplified by the amplifier in the PCM Codec (IC501) and the ALC (IC503), then input as the external (microphone) to the PCM
Codec (IC501) again
The ALC (IC503) works in the same way as the IC502.
3. In the PCM Codec (IC501), after the audio signal is switched between the built-in microphone and the external microphone by

14
BB-HCM511A/BB-HCM531A
a register setting from the host, amplification, AD conversion and gain adjustment are performed.
The sampling frequency of the A/D conversion is 8kHz and it is converted to the PCM in the format of 8bit and µlaw. Then,
64kbps data are output to the IC102 on the CPU board through the Serial I/F.
The data transfer of the Serial I/F is BCLK (256 kHz).
4. The data compression of 32kbps is performed in the ADPCM Block inside of the IC102 and the data transferred as audio data.
[Speaker audio]
1. The ADPCM audio data are sent from the PC and, after data decompression in the ADPCM block of the ASIC (101), the data
are transferred as the audio data of 64kbps to the PCM Codec (IC501) through the Serial I/F.
2. After the µlaw to linear conversion, amplification and DA conversion, they are output to pin 2 of the speaker jack (CN504) as
audio output signal in the PCM Codec (IC501).
4.5. LAN Block
Composed of ETHERNET MAC Block inside of the IC102 and the IC105 (ETHER-PHY) on the CPU board, and the T501
(Transformer) and the CN601 (RJ45 jack) on the PoE Board.
The T605 (Transformer) obtains isolation between the Set and the Ethernet.
ETHERNET MAC and the IC105 (ETHER-PHY) are connected by a signal called MIIBus and it makes Ether net data sending
and receiving possible.
Sending
The communication data sent from the IC102 is converted to Ethernet signal (100Base-Tx, 10Base-T) at the IC105 and sent
from the CN601 through the T601.
Receiving
The Ethernet signal received from the CN601 is converted to the communication data at the IC105 and received to the IC102.

15
BB-HCM511A/BB-HCM531A
4.6. Pan and Tilt Motor Control Circuit
Pan and tilt are conducted by controlling the motor driver (IC108) using the signal from GPIO inside of IC102, which is mounted
on the CPU board. Also, detection of a home position for operating the pan and tilt are done with the pan photo sensor (IC116
on the CPU board) and the tilt photo sensor (IC2 on the FPC board). This detected signal is transmitted to GPIO at IC102 after
being shaped at IC107.
4.7. Power Supply Block
• +3.3V is brought about by the power supply of +12V from the PoE (Power over Ethernet) circuit on the PoE board via the DC-DC
converter circuit composed of IC114, IC111.D102, L121, and C249.
• +1.2V for an internal circuit of IC102 is generated by the series regulator (IC117).

16
BB-HCM511A/BB-HCM531A
4.8. PoE Block
[Power receive]
The power supplied from a LAN cable receives voltage (48 V) via a diode bridge from a RJ-45 connector (CN601) on the PoE
Board.
There are 2 types of PoE receiving methods; a type using unused pins (4, 5, 7 and 8 pin) for LAN data transmission and a type
using the mid point of data lines (1, 2, 3 and 6 pin). This product is compatible with both types because it is equipped with 2 lines
(D601 - D604 and D605 - D608) of diode bridge circuits
The outputs of the 2 diode bridges described above are connected to the same poles and supply the subsequent circuits + and -
powers.
[PD certification circuit]
The voltage obtained from the diode bridges is supplied to the PD control IC (IC602) of PoE.
The IC601 performs the following operations with the applied voltage from the supply side of power.
For applied voltage of 2.8 - 10 V from the supply side, it returns the internal resistance value of IC601 (25 kΩ).
For applied voltage of 15.5 - 20.5 V from the supply side, it returns the current value by the resistor connected to the Pin (5) of
IC602. (This product is resistance value (open) and it is designed with Class 0 specification.)
When 48 V is applied as the certification progresses, it conducts between the Pins 7 and 10.
[Voltage drop section]
When the power of 48V is supplied to the following DC/DC converter section based on the PD authentication, voltage is con-
verted by control IC (IC601), output FET (IC602), switching transformer (T601), rectification diode, and capacitor (C622), which
results in output of +12V.
[Switching with AC adaptor]
There is a DC jack (CN501), to which an AC adaptor is connected when POE is not used, and +12V is input from the AC adap-
tor. Switching of +12V from the PoE circuit is conducted by using diodes (D621, D501).

4.9. Others
[I/O Terminal]
• The Input terminal has two systems; both of them are connected to the Input Port of the IC102 GPIO.
• Due to Internal Pull-up Resistance, the PNP Transistor (Q502, Q503) on the following level is usually in the OFF state and the
Input Port connected to the collector is at L level.
• If the terminal is short-circuited with the GND or the signal of L level is input, the PNP Transistor goes ON and the Input Port
goes to H level.
• The CPU checks the state of this port regularly to detect a change in this signal.
• The Output terminal is controlled by the Output Port of the IC102. When the Port output is L, the transistor (Q504) on the follow-
ing level is OFF and, when the output is H, the transistor is ON. This transistor has open collector output and it controls external
equipment via external pull-up.
[Clear Setting SW]
• The Clear Setting SW (SW102) is connected to the Input Port of the GPIO. It is usually at H level and goes to L level, when the
SW is pressed.
• The CPU monitors this Input Port periodically and, if it detects that this SW is pressed longer than a specified period, the setting
values other than the RTC are returned to factory settings.
[LED]
• The LED (LED501) has two-color LEDs (red and green). When the transistor (Q505, Q506) connected to each LED is turned
ON/OFF via the Output Port of the IC102, it controls the ON/OFF of the LED.
