located at the bottom of the patient monitor. The battery power is introduced to the power module via the battery

interface board, and then processed and distributed to each component by the power module.

NOTE

 Two batteries must be used simultaneously when the patient monitor operates on battery power.

Battery Interface Board

The battery interface board connects batteries to the power module, enabling charging and discharging between the

batteries and the power board.

Power Module

The power module is located at the back of the patient monitor. The main part of the power module is the power

board, which contains 4 PCBs: charging & power management board, voltage drop DC inverter, voltage rise and drop

DC inverter, and voltage drop 5 V CIS power board.

The power module transforms the input power into DC and supplies each component of the patient monitor. The

input power comes from either the batteries or an AC source. The patient monitor will run power from the AC source

whenever an AC source is available. If the AC source is not available, the patient monitor will automatically switch to

battery power. This does not affect the monitor’s operating status.

Power module has an AC input socket at its backside, and a socket at its front provides 4 connections to the batteries,

main board, iView components and USB interface board respectively. The power module protects itself and the

patient monitor by switching off AC input or DC output in case of overcurrent, short circuit and overvoltage.The

power module provides 4 DC outputs:

Outputs Description

+3.3 VDC Goes to the LCD, mother board, CPU board, DVI interface board and integral module rack.

+5.0 VDC Goes to the DVI interface board, recorder, CF storage card board and USB interface board.

+5.0 VDC CIS Goes to the iView assembly.

+12 VDC

Goes to the recorder, LCD inverter, integral module rack, parameter modules and USB

interface board.

2.3.5 Equipment Interface System

USB Interface Board

The USB interface board is compatible with such USB interfaces as USB2.0, USB1.1 and USB1.0. It is connected with the

main board and the power module. It receives USB differential signals coming from the main board and then

distributes them to a maximum of six USB interfaces via two ISP1521 chips. The USB interface board of the iView

system directly connects to two USB interfaces (on the USB board) of the host. The UART signal output by the main

board is converted into RS422 signal by the USB interface board. The USB interface board receives 5 VDC and 12 VDC

inputs from the power module, of which the 5 VDC goes to the USB interface board and the 12 VDC outputted to the

SMR connector through a fuse.

2.4 Parameter Module

Each parameter module consists of the module infrared communication board, module power board, module button

board, parameter board, etc.

2.4.1 Module Infrared Communication Board

The module infrared communication board allows a short delay when powering up the module and adopts FPGA to

enable infrared communications between the module and the module rack. An ID is integrated into the module

infrared communication board. When a module is inserted in the module rack, the ID is automatically sent to the

module rack.

2.4.2 Module Power Board

Some modules have no power board. There are two kinds of module power board:

1. Isolated power board: converts the 12 VDC into a 12 V isolated DC and a 5 V isolated DC.

2. Non-isolated power board: converts the 12 VDC into a 5 VDC.

2.4.3 Parameter Board

The parameter board is a parameter measurement component.

Passport 17m Service Manual 2-13

2.5 Satellite Module Rack

The satellite module rack (SMR) is independent of the patient monitor, provides 8 slots for mounting parameter

modules. It has the following features:

 It allows a parameter module to be plugged and unplugged with the patient monitor on. This allows function

extension and patient transfer.

 The SMR receives 12 VDC through a powered USB cable coming from the 17m monitor. It then supplies power to

each parameter module via the contact screw.

 It accomplishes communications protocol conversions between the patient monitor and each parameter module,

provides infrared communications for parameter modules, and is responsible for detecting infrared

communications malfunction for each parameter module.

The following diagram shows the structure of the SMR.

2-14 Passport 17m Service Manual

2.6 BeneLink Module

The BeneLink module allows the information (patient data, alarms, etc.) from the external device to be displayed,

saved, recorded, printed, or calculated through the patient monitor. If the patient monitor is connected with the CMS

or gateway, information from the external device can also be transmitted to the CMS or gateway. The BeneLink

module connects with the external device through an ID module, which enables the information transmission

between the BeneLink module and the external device. The BeneLink module can be connected to many external

devices such as anesthesia machines and ventilators.

The following diagram shows the structure of the BeneLink module:

described in the table above.

 Components of the main unit, SMR and parameter modules are powered by the power module. In the

event that a component malfunctions, verify the operating voltage is correct. Refer to 2 Theory of

Operation for the operating voltage and measurement points for each component.

5 Repair and Disassembly

5.1 Tools

During disassembly and repair, the following tools may be required:

 Phillips screwdrivers
 Small flat-bladed screwdrivers
 Tweezers
 Needle-nose pliers
 Hex nut driver or socket wrench

5.2 Preparations for Disassembly

Before disassembling the monitor:

 Stop monitoring the patient, turn off the monitor and disconnect all the accessories and peripheral devices.
 Disconnect the AC power source and take out both of the batteries.
 Remove all the modules in the integral module rack. If the SMR is connected, disconnect the SMR from the

monitor and then remove all the modules in it.

WARNING

 Before disassembling the monitor, be sure to eliminate any static electricity charges. When

disassembling the parts labeled with static-sensitive symbols, make sure you are wearing electrostatic

discharge protection such as an antistatic wristband or gloves to avoid damaging the equipment.

 Carefully position cables and wires to avoid short circuits and/or pinched tubing when reassembling the

monitor.

 When assembling the monitor, be sure to use the specified screws. If an incorrect screw is tightened by

force, the monitor may be damaged and the screw or the part may fall off during use and cause

unpredictable damage or human injury.

 Be sure to follow the correct sequence when disassembling the monitor. Be sure to disconnect all the

cables before disassembling any parts. Take care not to damage any cables or connectors.
