4 Technical Descriptions
4.1.
The Sensor Camera
CPU board & LED board (LED board:BL-C160 only)
4.1.1.
CPU Block
CPU (IC101)
Operating Power Supply: 3.3V (for I/O) 1.2V (for Core)
Package: 344 pin LGA
Outline of Operation:The LSI component encodes image signals input by a camera to JPEG or MPEG format and distributes
data to a terminal connected to an IPv4 or IPv6 network using a network server function realized by software processing in a
built-in processor.
CMOS sensor (IC201) and Real Time Clock IC (IC3) are accessed by I2C I/F. Ethernet PHY (IC171) is accessed by MII (Media
Independent Interface) I/F.

4.1.2.
LAN Block
Consists of IC101 (CPU), IC171 (ETHER-PHY), T1 (Trans) and CN171 (RJ45).
T1 (Trans) insulates sets and Ethernet.
IC101 (CPU) and IC171 (ETHER-PHY) are connected by a signal called MIIBus which it makes it possible to transmit/receive
Ethernet data.
IC171 has Auto Negotiation Function which changes 10BASE-T or 100BASE-TX automatically.

IC171 has Auto Negotiation Function which changes 10BASE-T or 100BASE-TX automatically.
Transmitting Operation
Electric signal from IC101 is changed to Ethernet data on IC171 and it is sent through T1 from CN171.
Receiving Operation
Ethernet data from CN171 is change to electrical signal on IC171 and it is received by IC101.
Electric signal from IC101 is changed to Ethernet data on IC171 and it is sent through T1 from CN171.
Receiving Operation
Ethernet data from CN171 is change to electrical signal on IC171 and it is received by IC101.
Besides the previously mentioned Ethernet data, CN171 includes power from an AC adapter (9VDC) and external sensor signal
input from a stand unit.
