Software packages and software options
Software packages
The Dash patient monitor comes configured with the Basic software package. This
package consists of standard-of-care parameters, lethal arrhythmia detection, dose
calculations, and features required by clinicians caring for acutely ill patients.
Two additional software packages can be purchased separately or in any
combination. These packages provide a variety of features that allow the patient
monitor to be configured to best meet the needs of its intended environment.
The Cardiac software package focuses on cardiac conductivity. Its features include
full arrhythmia analysis and storage, as well as ST segment trending, storage, and
templates. The ability to adjust the ST measurement point is also included in this
package.
The Cardiopulmonary software package centers on cardiac and pulmonary
hemodynamics. Features include the PA insert and wedge algorithms, the intraaortic balloon pump algorithm, and the thermodilution cardiac output algorithm,
including predefined computation constants for the catheters of major
manufacturers. Also included are cardiac and pulmonary calculations.
Software options
Three software options can be purchased separately or in any combination with the
software packages and software options.
The High Resolution CRG Trends option provides storage of up to 100 CRG events,
and up to 24 hours of CRG trend data, in addition to the CRG feature set found in
the Basic software package.
The 12SL™ ECG analysis program with Gender Specific Criteria and the Acute
Cardiac Ischemia–Time Insensitive Predictive Instrument (ACI-TIPI) analysis
option uses recorded ECG data to produce a numerical score which is the predicted
probability of acute cardiac ischemia. In addition, the gender-specific criteria
improves the detection of acute myocardial infarctions (AMI) in women.
The Unity Network option enables you to view other patients on the network,
interface with a central station and other network devices, and perform Combo or
Rover Combo monitoring.

About Ethernet
The GE Unity Network uses Ethernet for device to device communications. This
local area network links all patient monitors, clinical information centers, and other
GE equipment throughout the hospital. Depending on the construction of the
hospital, thick-net, thin-net, or CAT-5 twisted pair cabling is used. The Dash patient
monitor is designed to be used with twisted-pair cabling. Consult GE when trying to
interface with either thick-net or thin-net cabling. The real-time GE Unity Network
operates at 10 Mbps, half-duplex.
Twisted pair
Twisted pair is the most popular cabling because it is easy to install and flexible to
work with. It uses the star topology with a switch as the hub of the segment. A
maximum of 100 meters or 328 feet is the longest length of twisted pair cable
allowed. The maximum number of devices on the GE Unity Network is 1,000.

Equipment overview: Ethernet communication
Network Terms
Node
Each network device or node is assigned a Media Access Control (MAC) Address
number and requires a network connection to interface between the network device
and the network.
Media Access Control (MAC) address
A 48-bit address assigned by the manufacturer to uniquely identify a node of the
network. This is also known as the Ethernet address.
Switch
To implement the star topology, each network device is connected to a network
switch. The switch passes all network data between each network device in the star
segment. Typically, the switch supports 12 to 48 network devices and may be linked
to other switches to form larger networks.
Segment
IP address
Subnet
A network segment is comprised of all devices connected to one or many switches
which are in-turn connected together to form a larger network. The boundaries of the
segment are defined by networking equipment that regulate the flow of packets into
and out of the segment (e.g. routers and switches).
A 32-bit (IPv4) address assigned by the user (either statically or dynamically from a
server) to uniquely identify the packets from a device for routing purposes.
A subnet is a logical segment of a larger network that shares a common IP address
range as defined by a subnet mask. Proper subnetting can improve the performance
and security of a network.

Theory of operation
Components
The patient monitor is housed in a single package. The main components of the
assembly are:
Power supply
Data Acquisition System
Processor and power management subsystem (incl uding battery case and
The subsystems within the patient monitor operate from a common 9 to 18 V power
bus. Due to the wide variety of voltages required by the various subsystems, power
is converted locally by each subsystem. This architecture results in an efficient and
compact system by reducing the number of conversions required and optimizing the
physical size of each converter for the specific application.
When operating on AC mains power, the power bus voltage is 18 V, generated by
the offline switching power supply.
No AC mains power switch is provided.
The line voltage range switch must be set to select 115 V or 230 V (90 to 132 VAC
or 190 to 264 VAC, respectively).
Data Acquisition System (DAS)
All interfaces to the patient occur through the DAS. The ECG function uses a direct
connection to the patient; therefore it is separately isolated from the other functions
(except respiration, which shares the ECG patient interface) to substantially reduce
coupling of noise and leakage currents to/from other functions. All remaining DAS
functions (e.g., pulse oximetry, NBP, invasive pressure, temperature, cardiac output,
and CO
) share a common isolation barrier.

Overview
The main processor/power management PCB contains the electrical hardware to
provide data processing and display of patient and monitor configuration data,
communication and interface circuitry, and power conversion and battery
management functions for the patient monitor.
The high level of integration attained in the design of the processor/power
management PCB is attributed to the use of several highly integrated devices. A
complex communications controller, ASIC, and battery management hardware
significantly improve the performance and reduce the complexity and cost of the
assembly. In addition to the CPU, the main microcontroller contains a six-channel
communications processor as well as memory, PC Card, and video controllers. The
devices used in the core processing architecture all operate at 3.3 V to minimize
power consumption, yet the main processor and ASIC are tolerant of 5 V hardware
peripherals.

System Phase-Locked Loop (SPLL)Generation of system clock from crystal
The microprocessor supervisory circuit provides reliable operation of the main
processor board. This circuit monitors the +3.3 V power supply and asserts a 140
mS active low reset pulse when the power supply voltage is below +3.0 V during
power-up and power-down conditions. A 3 V, 0.5 A hour lithium battery is used to
preserve the contents of two SRAM devices and a real-time clock (RTC) when VCC
is below the reset threshold.
System control logic
The system ASIC contains all of the system control logic for the processor/power
management PCB. Such functions include address decoding, peripheral read and
write control strobes, smart battery control logic, display control, multiple I/O ports,
and front panel key switch debouncing.
Memory
Eight megabytes of non-volatile memory are provided to support the boot code and
expansion memory such as high resolution graphic trends data storage. The boot
block is write protected.
Eight megabytes of non-volatile memory are provided to support the main software
application code.
Sixty-four megabytes of volatile memory are provided by the synchronous graphics

Two analog output channels support ECG and BP. The pace pulse is generated on
the main processor board and inserted into the analog out ECG signal. The digitalto-analog conversion for both ECG and blood pressure output signals are performed
on the main processing board via a two channel 12-bit serial DAC. Cal data is stored
on the processor/power management PCB.
The QRS complex of ECG data acquired from the DAS generates the marker-out
signal. A software selectable pulse width and pulse amplitude is provided in the
Boot Loader Menu.

Optional thermal printer
The thermal printer includes complete control of the print head to print the desired
waveforms and text as well as monitor power consumption. The host processor on
the main processing board has direct communication via an 8-bit data bus to the
processor residing within the thermal recorder.
The +9-18 V power supplied to the writer is heavily filtered to provide the storage
capability to smooth power surges and transients caused by abnormal thermal
printing. Such printing may occur if the patient monitor is subject ed to ESU noise.
In addition, a writer current limiting circuit restricts the current to the writer to 2.5
A. If this current limit is exceeded, the circuit faults and requires the current limiting
circuit to reset through a microprocessor port.
Optional alarm light indicator
An alarm light indicating two levels of visual alarms resides in the handle of the
Dash 3000 patient monitor and in the display bezel of the Dash 4000/5000 patient
monitors. Red and yellow alarm lights illuminate by addressing an ASIC output
port. The Dash 3000 alarm light interfaces to the processor/power management PCB
via the 40-pin writer interface. The Dash 4000/5000 alarm lights interface to the
processor/power management PCB via the 100-pin DAS/Display /Keyboard
interface.

PC card
The main processor contains a PC Card controller, which complies with the
PCMCIA standard. One 68-pin fully compliant Type II PC Card slot is supported in
this design for wireless card.
Peripheral expansion interface
A 20-pin peripheral expansion interface is provided to support future use. An active
low peripheral present signal may be polled by software to identify when a
peripheral is attached to the patient monitor. Asynchronous, AUX, and a switched
Ethernet serial communication channels are supported as well as switched +9-18 V
and +5 V power.
DAS communication
The microprocessor communicates with the DAS processor using the second serial
communication controller (SCC) of the communication processor module (CPM).
This asynchronous communication channel operates at TTL levels and is optically
isolated within the DAS.

Equipment overview: Theory of operation
Optional Unity Network communication
The microprocessor provides an Ethernet controller, which is implemented on SCC1
in order to benefit from the additional buffer descriptors compared to SCC2.
Ethernet packets are stored in SRAM buffers and are transmitted and received by the
10BASE-T transceiver. The Ethernet clocks are generated from a 20 MHz crystal
oscillator circuit and the transceiver. The transceiver also provides a visual
indication in the form of four LEDS to identify packet transmit, receive, collision,
and link integrity. The status of received data is indicated by the link integrity signal,
which is used by the microprocessor to determine if the patient monitor is connected
to the Unity Network.
An isolation transformer provides basic insulation to the twisted pair interface
required to meet the ANSI/IEEE 802.3 standard (Ethernet). Isolation is required
because during transport the power cord with the ground conductor is not available
to provide a path for a fault condition. An 8-pin RJ-45 port containing two isolated,
differential pairs is provided to connect the patient monitor to a network hub.
NOTE
Power is not provided in the twisted pair interface as in the attachment user
interface (AUI) of other monitoring products.
Ethernet priority
Async communication
Ethernet communications are prioritized in the following order.
1.Top priority is the Peripheral Expansion interface.
2.Next priority is the Hardwired Ethernet connection at the back of the patient
monitor.
3.Lowest priority is the optional wireless connection.
If none of the above exist, then the patient monitor is a stand-alone monitor.
Asynchronous communication ports comply with the GEMMS AutoPort protocol
and are provided through an 8-pin RJ-45 port and the 20-pin peripheral interface
described in the next section.

Debug patient monitor and diagnostic LEDs
An integrated debugger operating in the debug mode within the main processor
provides basic emulator-like features such as modification of register and memory
locations and setting of breakpoints. The connector required for this serial
communication is a dual row 10-pin header. This connector is located within the
patient monitor and is not intended for field service use. Tracing of instructions and
logic analysis is provided by an adapter board that connects to a socket installed on
the main processor board instead of the microprocessor.
Three diagnostic LEDs located along the front edge of the board are provided for
general purpose use and are under software control. The LEDs interface directly to
port A of the microprocessor. A flashing green LED indicates normal monitoring
operation.
Main DC-DC converter section
The main DC-DC converter consists of two independent synchronous rectifier buck
regulators with one common controller.
The patient monitor uses a “point of use” power conversion architecture with +9-18
V being the main power distribution bus.

Equipment overview: Theory of operation
Lithium-Ion battery power
The patient monitor is designed to operate on battery power during transport or
whenever AC power is interrupted. A complete battery management system allows
you to obtain maximum battery performance. Audible and visual alarm s alert you
when loss of power is imminent and on-screen capacity gauges indicate battery
charge condition and capacity.
Depending on usage, you can get up to 2.5 hours of run time per battery for new,
fully-charged batteries. Monitoring NBP, CO2 and SpO2 drain battery power faster
than other parameters. The display technology and brightness, graphing, and
connection to a wireless network can also alter battery run times.
NOTE
A BATTERY LOW message at the top of the screen warns you prior to
complete loss of battery power. Replace the battery or connect the patient
monitor to an AC power source when the message displays.
The Lithium-Ion battery is a rechargeable battery containing Lithium-Ion cells. Each
battery contains an integrated electronic fuel gauge and a safety protection circuit.
Impact of Lithium-Ion Battery technology on the battery
The following are key points to know about Lithium-Ion battery technology:
The battery self-discharges on its own, even when it is not installed in a patient
monitor. This discharge is the result of the Lithium-Ion cells and the bias current
required for the integrated electronics.
The battery self-discharges. The self-discharge rate doubles for every 10 C
(18 F) rise in temperature.
The capacity loss of the battery degrades significantly at higher temperatures.
As the battery ages, the full-charge capacity of the battery degrades and will
permanently be lost. As a result, the amount of charge that is stored and
available for use is reduced.
How to improve battery performance
Installation guideline
Position the patient monitor in a location that does not artificially increase the
operating temperature of the battery.
To optimize battery life and performance, choose a location that does not
artificially increase the ambient temperature surrounding the patient monitor.
Do not place the patient monitor near a heat vent or near heat-generating
equipment, such as computer monitors.
Avoid placing the patient monitor in corners where the airflow may be
restricted.

Design Capacity and Full Charge Capacity
Charging guideline
Use the Cadex SMart Two+ charger to charge the battery instead of charging the
battery inside the patient monitor.
The Cadex SMart Two+ charger maintains a lower battery cell temperature
during the charge cycle than the patient monitor. This reduction in temperature
will extend the life of the battery.
The Cadex SMart Two+ charger charges one battery in less than 4 hours and
two batteries in less than 8 hours. When two batteries are used, the charger
applies half of the charging current to each battery.
Conditioning guideline
Remove the battery from the patient monitor every six months and condition it using
the Cadex SMart Two+ charger. This condition cycle recalibrates the electronic fuel
gauge.
Storage guidelines
Do not purchase more batteries than you will use in one year. The battery does not
have an indefinite shelf-life. See “How to store the battery” on page 5-12.
How to identify battery charge capacity
Battery capacity definitions
The following terms are used to define the capacity of the battery:
Design Capacity — The theoretical capacity of the battery cells when the
battery is new.
Full Charge Capacity — The actual amount of charge the battery can store and
deliver to the patient monitor.
Remaining Charge Capacity — The amount of Full Charge Capacity currently
remaining in the battery. This is a percent of Full Charge Capacity.
Identify battery charge capacity using the patient monitor
One new, fully charged battery lasts about 2.5 hours. Two new, fully charged
batteries last about 5 hours.
A battery that has 100% Design Capacity and is charged to 100% of this capacity
lasts approximately 2.5 hours. However, as the Full Charge Capacity declines, the
approximate run time of a fully charged battery will decrease.
Single battery run time: approximately 2.5 hours – An icon fully outlined with
solid lines and completely filled indicates a new battery, fully charged to its Design
Capacity.

Single battery run time: approximately 2.0 hours – The dotted portion of the

Capacity.
Single Battery Run Time: Approximately 1.0 Hours – The dotted portion of the
icon outline shows that the battery has lost 20% of its Design Capacity. The solidoutline portion is half filled in, showing that the battery is charged to only 50% of
available capacity.
Identify battery capacity using the Cadex SMart Two+
charger
When you select the Target Capacity switch on the charger, the charger compares
the battery’s performance to a 60%, 70%, or 80% target capacity set on the battery
charger. If the battery fails to meet the target performance, the battery charger will
prompt you to condition the battery. If after the condition cycle has been completed,
the battery does NOT meet the target performance, then the battery charger will
illuminate a “fail” light.

TIME TO FULL: — The time to full represents an estimate of the time
remaining before this battery is fully charged. Total recharge time for this
unit is the sum of both batteries’ time to full.
FUEL GAUGES — Explains the battery capacity gauges.
The fuel gauge is filled from the left to right proportional with the battery’s
charge level. The full rated capacity of a new battery of this type is represented
by a dashed outline. The maximum charge level for the battery currently
installed is represented by a solid outline. As a battery ages, its maximum
charge level becomes a smaller percentage of its Design Capacity. The solid
portion represents the current charge level of the battery as a percentage of its
maximum Full Charge Capacity.

ALARMS — Explains low battery and battery fault alarms and messages.
FAULT STATUS MESSAGES: — General, charging, and temperature
failures indicate that the battery has failed, or the charging of the battery
has failed. Replace it with a different battery.
CONDITION: — Condition this battery using an external battery charger.
LOW BATTERY ALARMS: — The patient monitor will issue a System
Warning alarm when there is approximately 10 minutes per battery run
time remaining. The patient monitor will issue a System Warning alarm
when shutdown is imminent (less than one minute left of remaining run
time).
The speaker is used for audible notification of alarms.
The handle serves multiple purposes in the patient monitor. The modular design
enables the user to add adapters for specialized applications.
Interfaces
Ethernet
AUX
The Dash 3000 handle houses the optional alarm light. This light is visible for 360°
surrounding the patient monitor. The light is intended for applications when the
audible notification is not useful or effective, such as noisy environments (e.g.,
emergency vehicles) or quiet environments (e.g., neonatal care areas). The alarm
light indicates two levels of visual alarms:
Crisis alarms (red LED) and
Warning alarms (amber LED).
The handle also houses the wireless card antennas required for the optional wireless
card subsystem.
The Ethernet RJ-45 port provides a hardware connection to the optional Unity
Network. The patient monitor has a built-in transceiver for twisted-pair wire. Basic
insulation (1500 VAC) isolates the patient monitor from networked devices.
The AUX RJ-45 port provides an asynchronous communication connection to
devices within the bedside care area. Basic insulation (1500 VAC) isolates the
patient monitor from other devices.
Defib Sync
The Defib Sync port provides signals needed to perform synchronized cardioversion
with a defibrillator. The Marker Out signal is a pulse with selectable amplitude and
width that coincides with the patient’s ECG R-wave. The Marker In signal is
2-40Dash 3000/4000/50002000966-456D
Peripheral expansion
Wireless LAN
Equipment overview: Theory of operation
returned to the patient monitor by the defibrillator. The Marker In signal causes the
patient monitor to insert a defib marker in the displayed ECG waveform.
This port also provides two analog signals: ECG and invasive pressure. The patient
monitor provides the top displayed ECG signal with reconstructed pace pulses. You
can use this signal to trigger a defibrillator or intra-aortic balloon pump. BP1
produces the pressure signal and is intended for triggering an intra-aortic balloon
pump.
Asynchronous communication, Ethernet (shared with the Ethernet RJ-45 port), 9-18
V power, 5 V power, and discrete I/O signals are provided in the peripheral
expansion interface ports. The expansion port pairs with the AC mains power inlet
to supply power to the patient monitor through a peripheral device.
Initialization
Initialization begins on a card insertion function call from card services. The card
insertion function checks the manufacturer and card ID.
Initialization includes:
Access Configuration Register - Set through card services to the manufacturer's
recommended value.
The MAC Address is set to the Dash's MAC address to provide seamless
transition from hardwire to wireless and back.
SSID - Set to stored value. This ID must be the same between a card and an
access point for them to associate.
Reception
The read task waits on a receive interrupt from the card. When awakened, the packet
length is validated and the packet is copied into an ethernet buffer. A transfer
function using byte-sized transfers is used to ensure the access time to the card is
minimized. The packet length and pointer is returned to the ethernet stream.
2000966-456DDash 3000/4000/50002-41
Equipment overview: Theory of operation
Transmission
The write task waits on a transmission packet to be queued. When awakened, the
card is checked for association to an access point and for an available transmit
buffer. Transmits are discarded if both are not true. The packet is copied into the
card and a transmit command is issued to the card. The transmit task waits on a
transmit complete interrupt from the card. This ensures a transmit buffer will be
ready for the write.
Error handling
The card does not support partial packets or other receive errors. On a transmit error
the buffer will not be resent. Other events like buffer and queue overflows are
reported through the error log system.
Association status
Each association change is reported through the error log system.
Command queue
Commands are queued if the Wait On Command (WOC) bit indicates the card has
not completed the previous command. Commands that must complete are issued
through a function call that ensures the command is completed before returning.
This function delays between each check of the card to allow other tasks to run and
must not be called with interrupts off or from within an interrupt.
Storage and backup
Program code storage
Patient monitor settings
Card enable/disable
The patient monitor network task determines which active network media should be
used for ethernet communication. The peripheral connector has the highest priority
followed by the rear connector then wireless. Interrupts to the wireless card are
disabled until an enable wireless call is made by the patient monitor network task.
Disabling the card simply turns these interrupts back off. Card events like
association changes and receive overflows may be logged when interrupts are
enabled, but this provides faster switch over between hardwire and wireless than
resetting the card and re-initializing it on an enable.
Executable program code for the main processor, DAS processor, and thermal
printer are stored in non-volatile programmable memory. To display the revision of
the currently stored code, access the submenu of the main application’s Monitor
Setup menu.
The processor/power management PCB stores default patient monitor settings in
non-volatile memory. The user must restore the original settings if replacing the
board.

Optional thermal printer
The patient monitor uses the same 50-mm th ermal p rin ter mo dule that is used in th e
PRN 50 stand-alone printer. It prints up to four waveforms at chart speeds ranging
from 0.1 to 50 mm/s. The printer software is loaded independently from the patient
monitor’s software.
In the patient monitor, the printer module limits its current consumption to stay
within its allocated system power budget.

will be moved from room to room. All combinations are explained below.
STANDARD—configures the patient monitor to stay in one room for stationary
monitoring only. Patient monitors not connected to the Unity Network (Ethernet
connection) must use STANDARD configuration only.
ROVER—configures the patient monitor to move from room to room for
stationary monitoring only.
COMBO—configures the patient monitor to stay in one room for both
stationary and ambulatory (telemetry) monitoring. This patient monitor displays
all Tram module data combined with ECG data for ambulatory patients.
NOTE
Users should be aware of a possible time discrepancy between the
waveforms from the Telemetry device and the waveforms hard-wired to the
Dash patient monitor. Users should not consider these waveforms to be
synchronous. If absolute synchronicity is desired, Combo mode should be
discontinued and the ECG waveforms should be acquired via the hardwired bedside patient monitor.
ROVER COMBO—configures the patient monitor to move from room to room
for both stationary and ambulatory (telemetry) monitoring.

TermDefinition
SSIDSSID is an acronym for Service Set Identifier.The SSID is a sequence of
numbers and characters that represents the ID, a name, of the wireless
network. For the 802.11b wireless Dash to connect wirelessly, the SSID
from the wireless network must match the SSID of the 802.11b wireless
Dash. A 802.11b wireless Dash has a default SSID of rtGEHClinical.
SECURITYA 802.11b wireless Dash provides three levels of security: NONE, WEP
128 bit, WPA-PSK (TKIP).·
NONE provides no security to the wireless communication
WEP 128 bit, Wired Equivalency Privacy, provides some level of
security, but it is less secure than WPA-PSK (TKIP).
WPA-PSK (TKIP), Temporal Key Integrity Protocol, is more secure than
WEP. TKIP has a method to change it's security key for each data
connection every second. For the 802.11b wireless Dash, WPA-PSK
(TKIP) is recommended.
PASS KEYPass Key is equivalent to passphrase. This is a sequence of words for the
wireless Dash to connect to a security enabled wireless network, WEP
128 bit or WPA-PSK (TKIP). When WEP 128 bit security is selected, the
wireless Dash generates the 26 hex characters for four different keys,
displayed in four different rows (1st row represents a key index of one, 2nd
row for a key index of two, 3rd row for a key index of three and 4th row for
a key index of four). One of these keys needs to match the WEP 128
security setting in the access point for the wireless Dash to communicate
properly. When WPA-PSK (TKIP) is selected, the wireless Dash will not
generate the 26 hex characters. Pass Key or passphrase needs to match
the WPA-PSK (TKIP) setting in the access point in order for it to
communicate properly.
KEY INDEX(only required for WEP 128 bit)
When WEP 128 bit security is selected, the wireless Dash and the
wireless network need to share a same key index.
