The Patient IO contains the electronics for ECG, phono and two analog inputs. One of the inputs has programmable gain. The module extracts respiration from ECG. The electronics also contains a pacemaker detector. The four inputs are separately isolated because of safety requirements. Inputs • Phono (from a phono heart microphone) •ECG / Respiration •AUX1 • AUX2 (Pulse/Pressure) These signals are optically isolated from the rest of the system. Outputs Serial Trace Data via Internal I/O to the SPD Board.Figure 5-25 Patient I/O - Block DiagramDigital Trace Data PHONO AUX 1 ISOLATION AUX 2 ECG / RESPIRATION (Pulse/Pressure) PHONO ECG AUX1 AUX2 A/D (Pulse/Pressure) to PC2IO

Resistor values were changed in the microphone amplifier circuit to increase the gain, a capacitor was added to reduce noise as well as a mofidified wiring scheme and differential pre- amp to reduce noise. This new FRU is backwards compatible.Figure 5-27 Internal I/O Module Overview 50M 50M Left Right Right LeftAUDIO OUT AUDIO IN RS-232C VIDEO OUT VIDEO IN SONY VCR SVO-9500MD A8 A9 A6 A7 A2 A11 A10 USB, +12PC, MIC IN, AUDIO OUT PC/VIC PC2IO D1 D2 Remote ECG MOD CD/RW FLOCK OF BIRDS(option) EthernetPC2IP SOUND CARD PCI VIDEO AGP VIDEO UPS CNTRL Mic In Line Out Line In 10/100 TUSB #1 USB #2COM1 COM2 ( EXT) Power from PCI/O-PC2IO Signals Cable PC MODULE Video Rcvr Op Control Audio Amp Mic Pre-Amp Video/Mic AC PowerSpeaker MONITOROP PANEL A1 A3 A4 A5 B5 B6 B7 B9 B8 B2 B1 B3 B4 A15 A14 TO CARD RACK TO INTERNAL I/O BOARD To AC CONTROL ASSY for FAN SPEED Regulation USER INTERFACE RS-232C Video Output B/W Video In SONY B/W PRINTER UP890MD SONY COLOR PRINTER UP-2900MD INTERNAL I/O BOARD PC MOTHERBOARD D3 D4D5 SVGA from AGPSVGA Out RGB & Sync SVGA VIDEOSVGA VIDEOCOLOR PRNT VIDEOCOLOR PRNT VIDEO TOUCH PANEL VIDEO TOUCH PANEL VIDEO PCI Bus to FEP Cardrack RGB Out

Another set of RGB can be fed to a color printer. • Composite video, black and white video and S-Video are buffered and distributed to VCR and printers. • The analog Doppler signals are fed from the Spectrum Doppler board to the VCR audio inputs and through a switch where audio from VCR playback also is input, to the BEP and then to the speakers. • Serial RS-232 interface signals from the BEP are fed to the destinations; VCR, Color Printer and Modem. • Serial USB interface signals from the BEP are fed to the Front Panel and to EIO. • Remote control signals for printers are generated on the I/O board. • The Footswitch is connected to the I/O board. • An AC Power Interface controls power on/off and fan speed.Figure 5-28 Internal I/O Back End Processor Connections
