1.3 INTENDED USE OF THE OXINET II MONITORING SYSTEM
The Oxinet II system is a PC-based patient monitoring system for use in the hospital
environment. It is designed to display, record, and store real-time physiological data
for up to 30 patients on wireless systems (Radio-link), or 16 patients with the hardwired system. This system gathers data from the Nellcor NPB-290, NPB-295, N395, N-3000, and N-3100, displays the data and stores information for future use at
a central location. Physiological data available with this system includes SpO
rate, respiration rate, heart rate, and noninvasive blood pressure (NIBP).
1.4 DESCRIPTION OF THE OXINET II MONITORING SYSTEM EQUIPMENT
1.4.1 System Overview
The major components of the Oxinet II monitoring system are the central station and
the bedside stations. The Oxinet II system components are illustrated in Figure 1-1

Figure 1-1: Oxinet II Monitoring System
Patient data is converted to a digital format at each bedside station and is transmitted
through a radio-link or hard-wired to the central station.
Refer to Figure 1-1. The central station consists of a computer, a monitor
(touchscreen optional), a keyboard, a mouse, an uninterruptible power supply, an
optional thermal printer, and an optional laser printer (not shown) supplied by your
facility. These components are described in the following paragraphs.
1.4.2.1 Computer
The computer is the primary component of the central station in the operation of the
Oxinet II system. Patient data from the bedside stations is processed by the
computer for display on the touchscreen monitor. The computer works very much
like a typical personal computer (PC). It contains a motherboard, a 3.5-inch floppy
disk drive, a hard disk drive, a video controller circuit board, and circuits for
interfacing with the keyboard and the mouse. The thermal printer (optional),
touchscreen controller circuit board, soundboard, and central radio transceiver in
radio-link units, or an I/O PCB, and expansion card in hard-wired units are
contained in the computer. The computer is housed in a standard mini-tower
enclosure.
1.4.2.2 Touchscreen Monitor
The Oxinet II system uses a 15- or 19-inch monitor with a color display. With a
touchscreen monitor, the operator touches the face of the screen to initiate or control
an Oxinet II system function.
1-2
1.4.2.3 Mouse
1.4.2.4 Keyboard
Section 1: Introduction
The mouse is used to move a pointer on the monitor screen to a desired location
such as over a key, button, waveform, or on-screen help index topic. The mouse has
two buttons. When either of the mouse buttons is pressed, it has the effect of
pressing the key or button, or selecting the waveform, or selecting an on-screen help
index topic that is under the mouse pointer. Positioning the pointer and clicking a
mouse button is the equivalent of touching the face of the touchscreen monitor at the
location of the key, button, waveform, or on-screen help index topic. The mouse
does not have to be connected to the computer to operate the Oxinet II system. The
function of positioning the pointer and clicking a mouse button can be performed by
touching the face of the touchscreen monitor where the key, button, waveform, or
on-screen help index topic is displayed.
The keyboard connected to the computer is a standard 101-key PC-type keyboard
used to enter alphanumeric patient data. The keyboard does not have to be
connected to the computer to operate the Oxinet II system. The operator can use an
on-screen keyboard where on-screen keyboard keys are pressed by touching keys
displayed on the monitor or by clicking the keys with the mouse.
1.4.2.5 Uninterruptible Power Supply
The uninterruptible power supply (UPS) provides operational power for
approximately 30 minutes for the central station should AC power fail. This allows
the system to be shut down in an optimal manner and avoids losing patient data.
1.4.2.6 Thermal Printer (Optional)
The thermal printer can be used to print data when an alarm condition has occurred,
ECG or plethysmographic waveforms, and trend information. The thermal printer is
housed in the computer.
1.4.2.7 Laser Printer (Optional)
An optional laser printer can be connected to the computer to provide printouts of
patient data and system status data. The central station is not supplied with this
printer. The printer must be provided by the facility. See the Specifications section
for minimum laser printer requirements.
1.4.3 Bedside Station
Every bedside station includes an NPB-290, NPB-295, N-395, or an N-3000 pulse
oximeter with an SPS or PSS power supply. An N-3100 monitor and an N-3200 can
also be stacked with an N-3000 as part of the bedside station. The N-3100 monitor
provides noninvasive blood pressure, and the N-3200 can provide waveform readout
at the bedside. These instruments monitor and process patient parameters and
convert the measured parameters to digital data that is sent to the central station.
Bedside stations in radio-link systems also include a remote radio transceiver
connected to the applicable monitor. Data is transmitted via the radio-link
communication configuration or hard-wired directly to the central station. Refer to
the NPB-290, NPB-295, N-395, N-3000, N-3100, and the N-3200 service and
operator's manuals, detailed descriptions of those monitors.
1-3
Section 1: Introduction
Note: All bedside station equipment must be powered by AC power to
communicate with the Oxinet II station.
1.4.4 Data Communication Configuration
1.4.4.1 Radio-Link
Radio-link communication can be used to send digital patient data from the bedside
station to the central station for processing and display.
N-3000: The N-3000 radio-link communication configuration requires that the
serial port for each N-3000 in the installation be configured in the EIA-232 format.
At each bedside station, a remote transceiver with a built-in antenna is mounted on
the N-3000. The serial port on the back of the N-3000 provides power for the
transceiver. The transceiver will not be powered if the N-3000 is running on battery
power.
Note: It will be necessary to reconfigure the serial port if the N-3000 is preset to
provide a nurse call. Set the configuration switches of the N-3000 to EIA-
232. Consult the N-3000 service manual for proper switch configuration.
NPB-290, NPB-295, N-395: When using an NPB-290, NPB-295, or N-395 monitor
for the bedside station the serial port setup must be set to baud = 9600 and protocol
= OXINET. An external radio transceiver with a built-in antenna is connected to the
serial data communications port on the rear of the NPB-290, NPB-295, or N-395
pulse oximeter.
1.4.4.2 Hard-wired
Note: All bedside station equipment must be powered by AC power to
communicate with the Oxinet II station.
Fixed frequency or spread spectrum radio communication and baud rate are
determined by software. Both systems broadcast in the 902 to 928 MHz range.
Systems broadcasting only SpO
2 use 2400 baud and systems with ECG use 9600
baud. The central station contains a central radio transceiver and is connected to an
antenna network of at least two antennas.
Note: Any system broadcasting ECG data will use the 9600-baud rate. If more
than 10 beds are being monitored, the fixed frequency system must be used.
An I/O PCB and an expansion card are used in hard-wired systems. Each PCB
comes with four channels that are configured to accept RS-422 signals. An
expansion card cannot be used without an I/O PCB. Each channel can be
individually configured to accept either RS-232 or RS-422 signals. (For more
information see section 2.5.3). A central station configured with two I/O PCBs and
two expansion cards can provide a maximum of 16 channels. All hard-wired
systems send data at 9600 baud. The RS-232 signal can be used for a maximum of
25 feet and the RS-422 signal can be used up to 4000 feet. Serial output data from
the NPB-290, NPB-295, N-395, and N-3000 pulse oximeter must be configured to
match the inputs of the channels in the central station. Central Stations in hardwired systems are configured for a baud rate of 9600.
1-4
Note: If the central station is being used with a hard-wired system, it may be
necessary to reconfigure the NPB-290, NPB-295, N-395, or N-3000 to the
RS-422 format. Consult the applicable operator's or service manual of the
respective monitor for instructions on changing the communication format.
Note: The central station cannot be configured with both radio-link and hard-wire
communications at the same time.
1.4.4.3 Minimum Software Requirements
Links cannot be established with Oxinet II if the software does not meet the
minimum software requirements. The minimum software requirements for monitors
communicating with the Oxinet II system are as follows:
NPB-290: All versions
NPB-295: All versions
N-395: All versions
N-3000: Software revision 3.0.0 or greater

representative.
This section provides general information on reconnecting your Oxinet II system
after installation and after moving it.
Before moving a bedside station in a radio-link system, contact Mallinckrodt's
Technical Services Department or your local Mallinckrodt representative to
determine the optimum location for the bedside station. Refer to the operator's and
service manuals for the individual monitor being relocated.
2.2 POWER REQUIREMENTS
Oxinet II system power cords must be connected to an approved, grounded outlet
capable of providing power for the Oxinet II system as indicated in the
Specifications section. This outlet must be close enough to the location of the
central station that only the power cord supplied with the uninterruptible power
supply (UPS) is used and a power extension cord is not used.
Caution: For USA locations, do not connect any components of the Oxinet II
system to an electrical outlet controlled by a wall switch.
2.3 CENTRAL STATION SITE SELECTION
When you are considering a location for the central station, you will need a location
that is accessible to the operator where the monitor is in full view of all who will be
looking at it. In addition to accessibility, you will need adequate counter space for
all components of the central station that will be used. Table 2-1 lists the space used
by each of the components of the central station.
2-1
Section 2: Equipment Installation and Hookup
Table 2-1: Central Station Component Space Requirements
Central Station Component Counter Space Requirement
Computer 22.8 cm (9 in.) x 38.1 cm (15 in.) x 43.2 cm (17 in.)
15-inch Touchscreen Monitor

Uninterruptible Power Supply 33.0 cm (13.1 in) x 9.0 cm (3.4 in.)
Keyboard 47 cm (18.5 in.) x 20.3 cm (8.0 in.)
Mouse (Typical mouse pad) (9.25 in.) x 20.3 cm (8 in.)
In addition to adequate counter space, consideration will also need to be given to
providing adequate ventilation space around the central station. There must be a
minimum of 1.5 inches from the top, front, sides, and back of all central station
components to any wall or other enclosing surface. Mallinckrodt recommends that a
minimum of 4 inches of space from the back of the computer be available for cables.
Do not put the computer or the touchscreen monitor inside a cabinet or other
enclosed space through which air cannot freely flow.

Monitors are purchased from different
manufacturers.
2.4 SELECTION OF CENTRAL STATION ANTENNA LOCATION
The central station antennas need to be a minimum of 6 feet apart and a minimum of
6 feet from the floor with their ground plates in the same horizontal plane. It is
recommended that the antennas be attached to the ceiling with the antenna elements
pointing down. The location of the antennas must accommodate an antenna cable
run that does not exceed the amount of cable supplied with each antenna. The
antennas should be as far away as possible from any wall or structure containing
excessive amounts of metal that could interfere with the radio signal. Contact
Mallinckrodt's Technical Services Department for the optimal location of the central
station antennas.
2.5 INSTALLATION OF HARDWARE
Hardware installation consists of placing the central station at the selected location
and placing components for each of the bedside stations. Connecting the necessary
cables and components to make the system operate properly as described in the
paragraph 2.7, System Interconnect. Once the system is installed and hooked up,
proper operation of the system can be verified by performing the procedures in
SECTION 1: Performance Verification.
2-2
Section 2: Equipment Installation and Hookup
2.5.1 Installation of Central Station Hardware
Place the computer and touchscreen monitor at the location selected for the central
station. The UPS can be placed in the same area as the computer and monitor or
further away such that the supplied power cords can be connected between the
computer and monitor and the UPS. The keyboard and mouse are not required for
operation of the Oxinet II system. However, if these components are used in your
facility, place them at the central station location. The exact placement of central
station components is determined by the needs at your facility.
Facilities with multiple central stations on fixed frequency could experience
problems with communication between a bedside unit and its central station. A
synchronization cable can be used to eliminate communication problems. It is
installed between the central stations to limit communication events to one station,
at any given point in time.
2.5.2 Installation of (Radio-link Transmitters) Bedside Station Hardware
Bedside stations that are monitored by the central station are composed of
NPB-290, NPB-295, N-395, and/or N-3000 pulse oximeters. Each bedside station
contains a radio kit. The N-3000 is equipped with either an SPS or PSS power
supply, or an N-3000 coupled with an N-3200, and a remote radio transceiver. An
N-3100 noninvasive blood pressure monitor can also be part of a bedside station.
When the Oxinet II system is shipped from the factory or when an N-3000 and/or a
remote radio transceiver are replaced, mount the remote radio on the N-3000.
Remove the adhesive backing from the quick-lock strips on the remote radio.
Position the radio with its cable hanging over the rear of the N-3000, and press the
radio down onto the top of the N-3000.
Set up each bedside station as described in the Oxinet II monitoring system
operator's manual.
2.5.3 Installation of (Hard-wired Systems) Bedside Station Hardware
Bedside stations that are monitored by the central station are composed of an
NPB-290, an NPB-295, an N-395, or an N-3000 pulse oximeter equipped with either
an SPS or PSS power supply. An N-3100 noninvasive blood pressure monitor and
an N-3200 waveform monitor can also be part of an N-3000 bedside station.
Channels on the I/O PCB and expansion card in the central station are configured to
accept RS-422 signals. Each channel of the I/O PCB and the expansion card can be
configured to RS-232. See Table 2-2. If an RS-232 signal is going to be used,
move the jumper for the channel to be changed into the RS-232 position. The
jumpers on the I/O PCB are numbered J1A through J4A. On the expansion card
they are numbered J1B through J4B. Labeling on the PCB's jumpers will indicate
how the channel is configured.
For wiring within the building, use Category 5 (EIA/TIA 568A) twisted-pair
shielded cable, 24 to 26 gauge, terminated to RJ-45 female connectors on both ends.
RS-422 can be used for distances up to 4000 feet and RS-232 can be used up to 25
feet. The pin outs are: one to one, two to two, three to three, etc, and are listed in the
chart below. The shield must be grounded at all bulkheads.
Note: Installation must conform to local building codes.

10. If the Central Station has more than one central transceiver PCB, install a
synchronization cable between the central transceiver PCBs as shown in
Figure 2-1. Up to three central transceiver PCBs can be used. One of the
PCBs will be designated Master and the others Slave. (Section 5, System
Configuration, describes how to designate the master PCB.) Plug the end of
the cable labeled M into the Master PCB and plug the S ends into the Slave
PCBs.
11. A power splitter/combiner must also be used in systems with more than one
central transceiver PCB. An incoming signal from the antenna is split into
two or three signals. The outputs from this cable must all be connected to the
same antenna input (all connected to A or all connected to B) on each of the
central transceiver PCBs.
12. Larger hospitals may have more than one Oxinet II station. Each of the
central stations may have more than one central transceiver PCB. Within
systems like these, only one central transceiver PCB can be the Master. As
with the cable in step 10, connect the end of the synchronization cable labeled
M to the Master PCB and the ends labeled S to the Slave PCBs.

13. Multiple fixed frequency systems will require an isolation box to be installed
between them. This will involve the synchronization cables and a
synchronization pulse isolation box. The cables will be standard telephone
wire with 6 conductors. Both ends of the cable will be terminated in a male
connector. Both ends of the cable will be wired the same (one to one). See
Table 2-3.
Table 2-3: Synchronization Cable Connections
The pulse isolation box has two sides that can be identified by the number of
connectors on each. The Master side will have only one connector. The
Slave side will have 4 connectors.

SECTION 3: PERFORMANCE VERIFICATION
3.1 Introduction
3.2 Required Test Equipment
3.3 Central Station Power-On Self Test
3.4 Electrical Safety Tests
3.1 INTRODUCTION
This section discusses the tests used to verify performance of the central station and
data communication interface with the bedside stations including the remote radio
transceiver. To verify the performance of the NPB-290, NPB-295, N-395, N-3000
and the N-3100 at the bedside station, refer to the individual service manuals for
those monitors.
3.2 REQUIRED TEST EQUIPMENT
No special test equipment is needed to verify the performance of the Oxinet II
system. An electrical safety analyzer is needed to perform electrical safety tests on
components of the central station.
3.3 CENTRAL STATION POWER-ON SELF TEST
An internal power-on self-test is used to verify performance of the Oxinet II system
following troubleshooting, replacement, and relocation of a central station
component. When the central station is turned on, an internal power-on self-test is
performed. Performance is verified when the Map screen is displayed after turning
on the central station and communication links are established with all active
bedside stations.
Note: When the central station is turned on, it may take several minutes for the
data files to be updated before the Map screen is displayed.
3.4 ELECTRICAL SAFETY TESTS
The safety test required for the components of the central station is a ground
integrity test. This test is to be performed on the computer, the touchscreen monitor,
and the UPS.
Refer to the service manuals for the NPB-290, NPB-295, N-395, N-3000, and
N-3100 for safety tests for those monitors.
The ground integrity test verifies that the integrity of the power cord ground wire
from the AC plug and connection with the chassis ground of the central station
component being tested.
1. Configure the ELECTRICAL SAFETY ANALYZER as follows:
Function: Ground Resistance Test
Range: mΩ
2. Connect the central station component's AC power cord plug to the analyzer
as recommended in the analyzer operating instructions.

Section 3: Performance Verification
3. Connect the analyzer resistance input lead to a metal contact on the outer case
of the central station component. Verify that the analyzer indicates 150
milliohms or less.
This concludes the safety test for the central station.
