•Always use set voltage.
- AC 100 ~ 240V (1.6A/50~60Hz)
- DC 12V(MAX 3.5A)
• All operating instructions must be read and understood before the products is operated.
• These safety and operating instruction must be kept in safe place for future reference.
• All warning in this instruction must be observed closely and be followed.
• Do not use attachments not recommended by the manufacturer. Use of inadequate attachments
can result in accidents.
• If you are not sure of the type of power supply used in your home, consult your dealer or local
power company. For units designed to operate on batteries or another power source, refer to the
operating instruction.
• The power cord must be routed properly to prevent people from stepping on them or objects
from resting on them. Check the cords at the plugs and products.
• Do not overload DC outlets or extension cords. Overloading can cause fire or electric shock.
• Do not attempt to service the products yourself. Removing covers can expose you to high voltage
and other dangerous conditions. Request a qualified person to perform servicing.
• If any of the following conditions occurs, unplug the power cord from the DC outlet, and request a
qualified service person to perform repairs.
a. When the power cord or plug in damaged.
b. When a liquid was spilled on the products or when objects have fallen into the products.
c. When the products have been exposed to rain or water.
d. When the products have been dropped or damaged.
e. When the products display an abnormal condition. Any noticeable abnormality in the products
indicate that the products need servicing.
• Upon completion of service of repair work, request the service technician to perform safety checks
to ensure that the products is in proper operating condition.
• Keep the products away from direct rays of the Sun-light.
• Do not place the products on an unstable cart, stand, tripod or table. Placing the products on an
unstable base can cause the products to fall.
• When you disassemble the products, you lay smooth fabric so that the products keep away from
scratch.
• When you assemble the products, you set the electronic screwdriver’s torque as less than 2k and
screw each bolt and check if the cables connect properly. Setting the torque as more than 2k can
cause the case broken.

•SDI Equalizer + Deserializer sends out YUV(4:2:2) 20bit digital Signal fed SD/HD-SDI. 20bit Signal as
in output sends out audio Signal.
•HDMI S/W, ADC(HDMI+ADC -Input) sends out 8bit 2ch R,G,B data selected DVI or HDMI signal.
YPbPr(480p,720p,1080i-Input) sends out 30bit 2ch R,G,B data via A/D CONVERTER.
•Analog R,G,B(IBM,VESA -Input) is sent out 30bit 2ch R,G,B data via A/D CONVERTER.
•ALTERA FPGA A makes DIGITAL Signal switching then send out ALTERA FPGA B.
In Fast Mode, it sends out ALTERA FPGA B by deinterlacing without using Scaler.
It sends out I2S Signal in H part by extracting Audio signal on SD/HD-SDI..
•3D-ROM handles with CVBS1~3.
•HDMI, DVI, RGB, and YPbPr don’t get a signal at the same time.
•After changing Digital signal into Analog one, Audio AMP(LM4849) amplifies audio then puts out
Audio Out(J16).
•SAMSUNG K4S641632H-UC75 memory is used for 3D-COM.
•Serial Flash Memory is a device that saves images and loads them when they are needed.
•CPU controls whole circuit.
•Temperature sensor and keys are under CPU control.
•Scaler/Deinterlace have 4 of DDR, save images, and load them whenever needed.
•PCF8574 ‘s role is to extend I/O port.
•GPI Remote(J23) consis of parallel switch then control monitors the outside.
•GPI IN/OUT(J21, J22) controls protocol monitors or supports TSL protocol.
•EXT. SYNC Generater takes out SYNC on Analog signal, makes CLK,H,V F, and puts out FPGA.
•Ethernet Module is for Program Download and Calibration by connecting an Ethernet Cable with
I2C signal.
•[Ethernet & USB]
- Updates new firmware such as features, debugging.
•~ AC IN
- AC 100 ~ 240V (1.6A/50~60㎐)
