5-4-10 UPS Battery Description
The UPS Battery is used in  these Back-End Processors:
• BEP1
• BEP2.0
• BEP2.2
• BEP4 used as BEP2.2 Replacement
• BEP4 used as BEP2.0 and BEP1 Replacement
The UPS batteries provide power to the Back-End Processor to enable a controlled shut down of the 
processor. 
NOTE: It is not possible to use the Vivid 7 for scanning or any other useful work without the mains  power. The UPS battery is only used as a powe r source for the BEP so it can do a controlled 
shut down, or be in standby modus without AC  Mains Power connected for a limited period of 
time, maximum 15 minutes.

5-4-10      UPS Batt ery Description (cont’d)
The UPS batteries will drain slightly  when the system is in the off condition. The off condition is defined 
as:
• Circuit Breaker in the OFF position
• System unplugged from the wall outlet
If the system is left in the OFF cond ition for an extended period of time (3  to 5 days or more), the system 
may not boot up or may beep when turned ON. Should this occur, the system needs to recharge the 
UPS batteries. This could take 15  minutes to as long as 10 hours uninterrupted, depending on the 
battery age, system input voltage and system temperatur e. To eliminate draining the UPS batteries, the 
system should remain plugged into the wall outlet with the circuit breaker in the ON position.

The Patient IO contains the  electronics for (refer to Figure 5-60): 
1.) Phono
2.) ECG/Respiration
3.) Analog inputs - AUX 1
4.) Analog inputs - AUX 2
The four inputs are separately isolated due to safety requirements.  Figure 5-60   The Patient I/O Connector Panel

5-5-1 Patient I/O Gene ral Description (cont’d)
The patient leads (for ECG) can be rotated by softw are (i.e. it is possible to change between Lead I, II 
and III by pushing a button). 
The module extracts respiration from ECG  signals from the ECG/Respiration input. 
The scanned image that is displayed, is synchroni zed with the ECG, respiration and phono traces. In 
M-Mode or Doppler, the traces are synchronized to  that particular modes sweep. The operator can 
control the gain, the position and the sweep rate of t he traces using the assignables on the control panel.
AUX2 is capable of handli ng a pulse/pressure signal. 
5-5-2 Patient I/O Location in the Unit
The Patient I/O is located inside the Back-End Proc essor with the connector panel available from the 
front of the system.

5-5-3 Patient I/O - Inputs
• ECG / Respiration
• Phono (from a phono heart microphone)
• Two Analog Inputs: -AUX1
- AUX2 (Pulse/Pressure)
5-5-3-1 Pinout for the AUX Connectors The pinout for the AUX connectors is described in the table below:
Both AUX1 and AUX2 are by default 1 Vpp (Volt pe ak-peak) inputs with a max frequency of 300 Hz. 
The inputs are differential. For a single ended sensor  signal, the pin 1 (input -) should be connected to 
the GND (ground) of the sensor. 
AUX2 has a programmable high gai n mode with a maximum input signal of 300 mVpp (millivolt peak-
peak).
5-5-4 Patient I/O - Outputs
• Serial Trace Data (SCSI  bus) to PC2IO or DGIO. 
(This version is used on all BEP1, BEP-2.x, BEP3 .0 and BEP4 used as replacement for BEP2.x.)
• Starting from the intr oduction of BT’05 and BEP3.2, a new  Patient I/O module with USB-1.1 
interface is used.
• Starting from BT’06 and BEP4.2, two Patient I/O models are supported: - Patient I/O module  with USB-1.1 interface
- Patient I/O module  with USB-2.0 interface

Internal I/O 
5-6-1 General Description
The Internal I/O module (IIO) is the interface betw een the Front-End Processor (Card Cage), the Back-
End Processor, and the rest of the system, incl uding the Operator Panel (Top Console) and the 
Peripherals. 
The IIO module performs buffering and distribution  of DC power, video, audio and control data as 
described in this list: 
• Video and audio signals are distribution betw een the Back-End Processor, External I/O, Top 
Console and peripherals.
• USB, Ethernet and RS232 signals are routed from  the Back-End Processor to the External I/O for 
external communication.
• USB signals are routed between the Back-End Processor and the user interface.
• Serial Bus signals are routed from the Back-End Processor to control VCR and UPS.
• Signals for power control and fan control are routed through the module. Figure 5-63   The Internal I/O module seen from different angles
