EQUIPMENT OVERVIEW: Components

Optional Wireless LAN System

Access Points

The flexibility of the GE Medical Systems Information Technologies Unity Network is increased by using the Wireless LAN system. The Wireless LAN system allows the user to roam from one access point to another, maintaining a strong, seamless connection to the Unity network.

The monitor, with its optional built-in Wireless LAN, functionally performs the same as a monitor connected directly to the Unity network. It can be viewed at the central station and by other GE Medical Systems

Information Technologies’ monitors on the network (i.e. Dash 3000/4000, Eagle 4000, and Solar patient monitors). Monitors with Wireless LAN sends and receives patient data via the access points of the Unity network.

NOTE: Wireless patient monitors that are moved from room to room

must have the monitor type configured as Rover or Rover/Combo monitoring.

To integrate the wireless network with the wired network, one or more access points are necessary. An access point connects the wireless monitor to the wired network infrastructure within the building, and acts as a bridge between the wired and wireless networks. The areas covered by each access point overlap to insure continuous coverage.

NOTE: The monitor will only work with a Symbol Access Point. The

monitor will not communicate directly with a Wireless LAN device from Aironet.

Ethernet Communication

Overview

Twisted Pair

Concentrator

Ethernet is a local area network used as the main link of the GE Medical Systems Information Technologies’ Unity network, a comprehensive

information communication system. The Unity network offers the high rate of communication of 10 megabits per second. The Ethernet connector connects to an Ethernet transceiver directly or via a transceiver cable. This local area network links all patient monitors, central stations, and other GE Medical Systems Information Technologies’ equipment throughout the hospital. Depending on the construction of the hospital, thick-net, thin-net, or twisted pair cabling is used.

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 concentrator as the hub of the segment. Each of the network devices is connected directly to the concentrator so longer lengths of cable are required. A maximum of 100 meters or 328 feet is the longest length of twisted pair cable used. The number of devices is limited to the amount of connectors at the concentrator.

The concentrator is simply a transceiver that passes all network data between any two branches in the LAN. Note that the concentrator passes all network data between the two branches, regardless of whether or not one node is sending data to another node on the same branch.

To implement the star topology, each network device is connected to a concentrator. The concentrator functions as a central hub and simply passes all network data between each network device in the star segment. Typically, the concentrator supports 8 to 12 network devices and may be linked to other concentrators to form larger networks.

3-6 Dash 3000/4000 Patient Monitor Revision A

2000966-035

INSTALLATION: Ethernet Communication

Node

Segment and Branch

Each network device or node is assigned an address number and requires a transceiver to interface between the network device and the network. For thick-net and thin-net cabling a transceiver and a serial drop cable connects to the main trunk. The serial drop cable is sometimes referred to as an AUI (attachment unit interface) transceiver cable. For twisted pair cabling, the transceiver to connected directly to the network device.

Some Ethernet systems are comprised of smaller, stand-alone Ethernet systems (called branches or segments) that are connected by bridges, concentrators, or repeaters. Many nodes on the Ethernet network may be serviced by one segment or branch. Each segment may support many patient monitors, central stations, and auxiliary devices.

For example, one segment may connect all the patient monitors and central stations in the ICU (Intensive Care Unit) and another may connect the monitoring system in the CCU (Critical Care Unit). Each segment could be a fully-functioning stand-alone system if they were not connected to each other. However, with a bridge or repeater to connect the ICU (one segment) with the CCU (the other segment), information can pass between any of the nodes (patient monitors and central stations) on either branch similar to a patient transfer from one unit to another.

A section is a single length of twisted pair cable with a RJ-45 connector on each end. A section goes from one twisted pair transceiver to the concentrator. A segment is comprised of all the sections of twisted pair cable connected in a star formation to one concentrator.

Repeater

A repeater is used to extend the length of cabling when the distance required exceeds the length of the cable specifications. It is simply a transceiver that passes all network data between any two segments. Note that the repeater passes all network data between the two segments, regardless of whether or not the one node is sending data to another node on the same segment.

Revision A Dash 3000/4000 Patient Monitor 3-7

2000966-035

INSTALLATION: Ethernet Communication

Bridge

Twisted Pair Cabling (10BaseT)

A bridge is more selective than a repeater with the data that it passes between segments. It also acts as a transceiver between two segments, but it only passes signals if a node on one of the segments is attempting to communicate with a node on the other segment. Since the majority of communication on the network occurs within a single segment, the bridge does not pass all of the data from one segment to the other. This lowers the amount of data traffic passing between segments, and makes the network more efficient than a system that is connected with repeaters.

Twisted pair is an IEEE 802.3 local area network that uses flat and small diameter cable containing four pairs of twisted wires to connect devices. Twisted pair operates at the same speed as thin-net and thicknet (10 megabits/second), but the cable distances extended up to 100 meters (328 feet).

A twisted pair transceiver passes data back and forth between the network device and the LAN. It is attached directly to the network device at the at the 15-pin D-type connector. The twisted pair cable is connected from the RJ-45 connector at the transceiver and the RJ-45 connector at the concentrator.

NOTE: Some devices (like Octacomm/Solar 8000M patient monitor)

have 10BaseT standard meaning that the RJ-45 connector is part of the product and the twisted pair transceiver is not required.

Symbol PC Card (Wireless LAN)

The Symbol PC card, installed in the monitor, uses a 2.4 GHz frequency band and a Frequency Hopping spread spectrum (FHSS). The Frequency Hopping spread spectrum meets IEEE 802.11 standards.

Two diversity antennas, installed in the handle of the monitor, radiates the RF energy through the air to a Symbol Access Point. The Symbol Access Point also uses a 2.4 GHz frequency band and the Frequency Hopping spread spectrum.

NOTE: Refer to the Wireless LAN (Symbol Access Point) Installation

and Service Manual for detailed information on the Symbol Access point.

NOTE: The following is required for the monitor to roam from access

point to access point while maintaining Wireless LAN communication with the Unity Network.

• Installation of the RF LAN (Wireless LAN) option.

• Configuration and verification of the monitor’s RF LAN operation.

• Activation of the RF LAN by disconnecting the monitor’s Ethernet cable.

Battery Maintenance

Charging

Conditioning the Batteries

Frequency Guidelines

The battery is charged whenever the monitor is connected to AC power, regardless whether the monitor is turned on or turned off.

A battery conditioning cycle occurs when the following has been completed.

1. The battery is fully charged without interruption.

2. The battery is discharged until the monitor shuts down.

3. The battery is charged until the battery status light turns green in color.

To maintain useful life, use the following guidelines to condition a battery:

• Once every two months,

• When the run time of the battery becomes noticeably shorter,

• When the predicted run times become noticeably inaccurate, or

• When the associated battery is requesting a conditioning cycle (i.e., the CHECK BATT STATUS error message is displayed in the ECG waveform area and CONDITION is displayed for BATTERY QUALITY in the Battery Status information window).

Recommendations

Procedure

Conditioning a battery is best done on an external charger (see instructions included with the charger). However, a conditioning cycle can also be run on the monitor.

To condition a battery on the monitor, follow this procedure:

1. Disconnect the monitor from the patient and remove it from service.

2. Insert the battery in need of conditioning in one of the battery slots in the monitor, and leave the other slot EMPTY.

3. Apply AC power to the monitor and allow the battery to charge uninterrupted until the Charging Status indicator on the front panel turns green.

4. Remove AC power and allow the monitor to run from the battery until it shuts off.

5. Apply AC power again to the monitor and allow the battery to charge uninterrupted until the Charging Status indicator on the front panel turns green.

Wall Receptacle Test

Ground (Earth) Integrity

Before starting the tests, the wall receptacle from which the monitoring device will get electrical power must be checked. This test checks the condition of the wall receptacle to ensure correct results from leakage tests.

For international wall receptacles, refer to the internal standards agencies of that particular country. Use a digital multimeter to ensure the wall receptacle is wired properly.

If other than normal polarity and ground is indicated, corrective action must be taken before proceeding. The results of the following tests will be meaningless unless a properly wired wall receptacle is used.

Listed below are two methods for checking the ground (earth) integrity,

“Ground Continuity Test” and “Impedance of Protective Earth Connection.” These tests determine whether the device's exposed metal and power inlet's earth (ground) connection has a power ground fault

condition.

Ground Continuity Test

Perform the test method below that is required by your Country/Local governing safety organization.

Completion of this test is checked by the following steps:

1. Disconnect the DUT (device under test) from the wall receptacle.

2. Connect the negative(-) lead of the ohm meter to the protective earth terminal (ground pin in power in-let connector) or the protective earth pin in the MAINS PLUG (ground pin in power cord). Refer to the US 120Vac power cord figure on the left.

3. Set the Ohm meter to the milliohm (mΩ) range.

4. Connect the positive (+) lead of the Ohm meter to all exposed metal surfaces on the DUT. If the metal surfaces are anodized or painted scrape off a small area in a inconspicuous area for the probe to make contact with the metal.

5. Resistance should read to pass:

• 0.1 ohm or less without power cord

• 0.2 ohms or less with power cord

Revision A Dash 3000/4000 Patient Monitor 4-11

2000966-035

MAINTENANCE: Electrical Safety Tests

Impedance of Protective Earth Connection

This test unlike a ground continuity test will also stress the ground system by using special ground bond testers i.e. Kikusui (model 872 or

TOS 6100) or Associated Research model HYAMP® Jr. Model 3030D.

This test normally is only required as a manufacturing production test to receive safety agency compliance (i.e. IEC601-1).

Some country agency's do require this test after field equipment repairs (i.e. Germany's DIN VDE 0751 standards).

Consult your country/local safety agency if in question.

Compliance is checked by the following steps:

1. A current not less than 10A and not exceeding 25A from a current source with a frequency of 50 or 60 Hz with a no-load voltage not exceeding 6 V is passed for at least 5 s through the protective earth terminal or the protective earth pin in the mains plug and each accessible metal part which could become live in case of failure in basic insulation.

2. The voltage drop between the parts described is measured and the impedance determined from the current and voltage drop. It shall not exceed the values indicated.

for equipment without a power supply cord the impedance between the protective earth terminal and any accessible metal part which is protectively earthed shall not exceed 0.1 ohms

For equipment with a power supply cord the impedance between the protective earth pin in the mains plug and any accessible metal part which is protectively earthed shall not exceed 0.2 ohms.

When taking this measurement move the unit's power cord around, no fluctuations in resistance should be observed.

WARNING

Duplication of an internet (IP) address on a network causes lost data. If you change the factory assigned internet address, you must first record all other internet addresses used on your network to avoid duplication.

An incorrect internet address may also prevent the monitor from viewing other monitors on the network even though the unit names match. Whether or not this can occur depends on the network topology at the installed site.

GRAPH TEST PATTERN—This menu selection allows you to run a graph test pattern. The choices are START and STOP.

TIME AND DATE—This menu selection allows changes to the time and date and may affect the time and date for the entire monitoring network. (Refer to Chapter 6, Configuration, for detailed procedures.)

WARNING

Loss of patient history. This menu should rarely be used because patient histories will be lost.

About the Monitor Error Log

Downloading the Error Log

Accessing the Review Errors Menu Option Item

The REVIEW ERRORS menu is an advanced troubleshooting tool used by GE Medical Systems Information Technologies’ engineering

personnel. Some of the information recorded in the monitor error log can be useful for field service troubleshooting.

This section provides an introduction to error log usage and meaning. Because the information contained in the error log is engineeringoriented, the intent of the manual is to simply provide a general understanding of this monitor function.

This section includes a method for downloading error log data over the network to a central station. Once downloaded to a central station, you can load the error log data onto floppy diskettes or review it on the central station.

To access the error log and learn more about the REVIEW ERRORS menu option item, follow these steps:

1. Rotate and press the Trim Knob control to select REVIEW ERRORS from the Service Mode Menu.

2. The review errors menu option items include four possible selections; one each for viewing output or input errors along with one each for clearing output or input errors. Rotate and press the Trim Knob control to scroll to and select VIEW OUTPUT ERRORS from the Review Errors Menu.

3. The RUN TIME ERROR LOG pop-up window appears on the left side of the monitor display. One time-dated output software error appears in the pop-up window at a time.

Use the Trim Knob control to scroll through each logged error and peruse all of the parameters associated with each output software error. Rotate the Trim Knob control to move the cursor (>) to a position for viewing the NEXT or PREVIOUS error as well as the position that allows the user to QUIT viewing output errors.

Selecting QUIT closes the RUN TIME ERROR LOG pop-up window and returns to the Review Errors Menu.

4. The VIEW INPUT ERRORS menu causes a RUN TIME ERROR LOG pop-up window to appear on the monitor display. The pop-up window now displays input software errors and provides basically the same information as the VIEW OUTPUT ERRORS pop-up window provided. The appearance of both pop-up windows are similar, the difference being errors that are logged as input versus output to/from the monitor.

5. To clear out the stored run time error logs, use the Trim Knob control to select the CLEAR OUTPUT ERRORS or CLEAR INPUT ERRORS menu, respectively.

Immediately after you clear one of the error logs, a message appears on the upper right side of the display. The message verifies the actuation of the Trim Knob control for this function.

Error Log Information

This part of the section describes in greater detail what information the error log contains and what can be learned from error logs.

An error log in the monitor can hold up to 50 events. As an event occurs, error information is stored in the log. Subsequent events are stored sequentially as they occur. When the 50-event limit is reached, subsequent errors replacing the oldest error(s) in the log.

A sample of the monitor error log pop-up window appears as follows:

When using the error log to troubleshoot a problem with the monitor, the following parameters from the pop-up window that are of greatest interest are:

• PROCESS NAME—The task that was operating when the event or problem occurred,

• ERROR CODE—A software code for the type of event or problem that occurred,

• SEVERITY—Indicates the level of impact of the event or problem on the system,

• DATE—The date the event or problem occurred,

• TIME—The time the event or problem occurred, and

Error Logs

Severity of the Error

• ERROR NUMBER—A sequential number used to identify each event or problem.

• INPUT ERROR—Additional information used to determine the cause of the error.

Error logs contain more than just operating system errors. Many events that occur that might have an impact upon the system are entered into the log. These logs may be requested by Tech Support on occasion to aid in troubleshooting the monitor. The logs are developed to aid engineering for internal diagnostics of the monitor. Contact Tech Support if you need clarification of any of the error logs.

Severity is a measure of how the event/error affected the system. There are three levels of severity. The following is a list of these levels accompanied by a brief description of each:

• CONTINUE—The event or error was logged, the task may or may not have completed, but the system was able to continue operating. Most error log entries have this severity level.

• FATAL—The event or error was logged, the task did not complete, and the system was unable to continue operating as recovery was not possible. This level of severity in an event or error is always followed by an automatic warm start.

• FORCED RESTART—The operating system restarted normally after a known condition, such as an Internet address change, patient discharge, etc.
