5-5-2 VIC Card
VIC Card perform video conversion operations and Power on/off control.
• Video Decoder : Video decoder convert S-VHS or composite video analog signal to digital RGB data
and send the RGB digital data into BEP main memory on motherboard through PCI bus. And then
this video digital data is displayd on console monitor. Video analog signal comes from rear panel.
This video decoder also have IIC bus interface logic.
• VGA to TV Convertor : This device convert the VGA display signal to TV display signal for B/W
printer and color printer and VCR recording.
• Shutter Control CPLD : Shutter signals for analog B/W printer and color printer are generated by
this CPLD. And this CPLD is controlled by video decoder via IIC bus.
• Power Control FPGA : This FPGA generates power on/off signal. This device is alive always by live
DC power which comes from JPC assy in AC Power Assy. So this device monitor the ststus of
power on/off switch on the keyboard. If power switch will be pushed once, this device turn on the
LV power supply in AC power assy and after few seconds, turn on the BEP assy.
5-5-3 Patient I/O (Option)
The optional Patient I/O is mounted at the front of the BEP chassi.
Available inputs:
•PCG
•ECG
•AUX1
•AUX2
