Unpacking the Monitor

The 91369 monitor, one or two batteries, external AC power supply, and any optional accessories are all
packaged and shipped in a single box. Keep at least one shipping box and its packing materials for re­shipping, if the monitor should ever require factory service.

Caution:

Observe precautions for handling electrostatic-sensitive devices!

Note:

• Never touch electrostatic-sensitive electronic components without following proper anti-static
procedures, including the use of an ESD wrist band and mat. An electrostatic discharge from your
fingers can permanently damage electronic components and cause latent failures.

• All static-sensitive electronic components are packaged in static-shielding bags. Retain the bag for
repackaging the component should you need to store it or return it to Spacelabs Medical for any
reason.

The monitor is typically shipped as follows:

Top Assembly — Contains the main enclosure with installed CPU, power supply, and I/O PCBAs.

Accessories — Contains the external DC power supply, U.S. power cord, international power cords (if

applicable), and any cable assemblies ordered.

Before installing the monitor:

Note:

When removing items from the shipping containers, ensure that you remove ALL components from each
container.

1 Unpack the received equipment.

2 Unpack the mounting hardware.

3 Conduct an equipment audit.

91369 Service Manual 2-1

Setup

Upon receiving the equipment, complete a detailed inventory to verify that the equipment you received
matches your order. This inventory must include serial numbers, model numbers, and all options and cables
received. Carefully inspect these items for shipping damage. If any damage is evident, immediately notify the
freight company and Spacelabs Medical.

Assembling the Monitor

Power and Battery Status

The three LEDs on the monitor indicate whether the monitor is connected to the AC mains power and the
status of any installed batteries. Battery status conditions are indicated as described in the following sections.

Figure 2-1: Battery status information

Power LED

Battery status

LEDs

Power LED

The power LED is located immediately to the right of the power ON/OFF switch. This LED is lit whenever the
monitor is connected to AC mains power via its power supply, and is not lit if the monitor is not connected to
the AC mains power.

Battery Status LEDs

These LEDs are only active while the unit is connected to AC mains power.

Unlit LED

A battery LED that is neither solid ON nor flashing indicates a battery is not present.

Solid Green LED

A solid green battery LED indicates that the battery is fully charged. Only a charging cycle or a faulty battery
will cause the green LED to flash, and these conditions only occur when a battery is installed in the monitor.

91369 Service Manual 2-2

Setup

Flashing Green LED — Battery Charging

A flashing green battery LED indicates an installed battery is being charged and the monitor is not completely
ready to be used in transport mode. This LED flashes in a constant pattern with no delays with the monitor
powered ON or OFF. The flashing is different than the battery fault detection flash.

Note:

The green LED stops flashing and stays ON when the charging cycle is complete.

Intermittent Flashing Green LED — Battery Fault Detected

An intermittent flashing green LED indicates that this battery will not hold a charge, or is taking too long to
charge. The intermittent signal is a repeating pattern of a solid green LED for one second and a flashing LED
for one second. An error message is also added to the error log for review by your system administrator.

To determine whether a battery is faulty, power the monitor ON using the front-panel switch and observe the
message displayed along the bottom of the monitor screen. Replace a faulty battery with the same battery
type.

Installing/Replacing Batteries

NiMH batteries are used in the monitor. Refer to Figure 2-2 to install one or two batteries.

Figure 2-2: Monitor battery installation

91369 Service Manual 2-3

Setup

While the monitor is operational, a single battery can be exchanged under any of the following conditions
without a loss of patient data:

• The monitor is being powered by the external power supply.

• The monitor is operating on two batteries, and one charged battery remains connected at all times during
the exchange.

Warning:

Batteries exposed to short circuit, high temperature, or fire may leak, vent, or explode.

Caution:

Follow the manufacturer’s recommended handling procedure. Collect and transport batteries in a
manner that prevents short circuit, compacting, mutilation, or any other abuse that would
compromise the physical integrity.

Connections

Refer to Figure 2-3 for available connections on the monitor’s rear panel. Refer to Figure 2-4 for available

Cabling

Maximum Cable Lengths

The following cables are limited to the indicated maximum length:

• SDLC Cable — 12.2 m (40 feet) maximum (total length from the monitor to the last device on the bus). For
longer SDLC cable runs, contact a Spacelabs Medical Field Service Engineer.

• Video Cable — 30.5 m (100 feet) maximum (total length from the monitor to the last display).

• Ethernet cable (10/100BaseT) — 100 m (328 feet) maximum.

SDLC External Devices

External devices (for example, Flexport® system interfaces) can be connected to the SDLC bus. (In this
context, the term “external” means connected to the SDLC bus by cable via an external connector. This is in
contrast to modules, which are connected by inserting them into a module housing.)

If no supplementary module housings are present (in addition to the module slot integral to the monitor itself),
then external devices are connected directly to the SDLC connector of the monitor.

If one or more supplementary module housings are present, Flexport devices are connected to connector J2
on one of the 90499 or 90491 supplementary module housings, or J3 on model 90485. Refer to the Module
Housings and Power Supplies Service Manual (P/N 070-0680-xx).

If multiple module housings are present, external devices must be connected to the last module housing in the
daisy-chain; that is, the housing electrically farthest from the monitor on the SDLC bus. Even though multiple
connectors may be available, only the SDLC connector on the most distal module housing can be used for
connecting external devices. Do not use more than a single Flexport connector, regardless of how many
module housings are present.

If multiple Flexport interfaces are to be installed, they must be daisy-chained using the T-cable supplied with
those devices. Up to three Flexport interfaces may be connected in this way.

Warning:

Unreliable system operation will occur if the SDLC bus is not correctly terminated or the maximum
cable length is exceeded. Flexport interfaces must be attached to the most distal module housing
on the SDLC bus.

SDLC Cable Interconnection

To ensure electromagnetic interference (EMI) compliance, the appropriate Spacelabs Medical
9-pin connector must be used. Refer to the Module Housings and Power Supplies Service Manual
(P/N 070-0680-xx).

91369 Service Manual 2-7

Setup

SDLC Bus Termination

The SDLC bus must be properly terminated for correct operation. If no external devices (for example, Flexports
or multigas analyzers) are connected, proper termination of the SDLC bus is accomplished automatically. If
external devices are connected, the switch on the module housing farthest from the monitor must be set to the
terminated ( ) position. All others must be set to the non-terminated ( ) position. The SDLC clock and
data signals are switched by the terminator switches and are not present “downstream” of any switch set to the

position.

Non-terminated Terminated

Figure 2-5: Terminator switch settings

Because bus termination is handled by setting the switches appropriately, an external terminator is only
required when external devices are connected.

If external devices are connected, an external cable terminator is required to terminate the SDLC bus. This
must be installed at the end of the SDLC bus (following the last external device). In this case, all module
housings must have their switches in the position.

Note:

Flexports require a powered Flexport cable (P/N 012-0555-00) when used with the 90491/90499 module
housing or 91369 monitor. SDLC data is only passed along to the external device(s) when the terminator
switch (SW2) is in the

position.

Alarm Relay

Alarm output signals are available at the Nurse Alert ( ) connector instantaneously when an alarm occurs.
Table 3 describes the connector pinouts for remote alarms. Figure 2-6, Figure 2-7, and Figure 2-8 illustrate the

Ethernet Network Connection

Caution:

• Only qualified personnel should attempt to connect a monitor to an Ethernet LAN the first time.

• Do not connect the monitor to an Ethernet local area network (LAN) prior to configuring the

following settings. The monitor must be properly configured for LAN access before you operate
the monitor. If you fail to correctly configure the monitor, you may interrupt other units also
using the LAN.

Note:

Detailed installation instructions for the physical Ethernet LAN are beyond the scope of this document.

91369 Service Manual 2-11

Setup

To connect a monitor onto an existing Spacelabs Medical Ethernet LAN, complete the following steps:

1 Install the monitor on a suitable table or shelf, ensuring that the air flow to the side air intake vents is

unobstructed, or use a Spacelabs Medical mounting option.

2 Ensure that the monitor is not connected to the LAN.

3 Plug the power cord attached to the monitor’s DC power supply into a standard hospital-grade AC power

supply.

4 Power ON the monitor.

5 Enter a unique MONITOR ID, BED NAME, and SUBNET for the monitor. Refer to Network Setup on page 2-

13 for more information.

6 Attach the 10/100BaseT LAN transceiver cable into the RJ45 connector on the left side of the monitor

(

 in Figure 2-4 on page 2-6).

7 Connect the other end of the Ethernet cable from the monitor to the nearest port.

8 Configure the monitor’s other network settings as necessary to ensure proper communication on the

network. Refer to

Network Setup on page 2-13.

Ethernet Network Disconnection

To remove a monitor from the LAN, disconnect the network cable from the 10/100BaseT network connection
(

 in Figure 2-4 on page 2-6).

Power-ON Test

Each time the monitor is powered ON:

• Diagnostic information displays for approximately 10 seconds.

• The embedded alarm light cycles red and yellow. Some models may cycle red, yellow, and cyan.

• Monitor keys display on the right side of the screen.

The monitor is now ready for normal operation.

External Devices

If an external SDLC device, such as a Flexport interface, is to be installed, the 9-pin SDLC connector on the
rear of the monitor or the module housing must be used. If multiple SDLC ports on module housings are
available, only the SDLC port on the module housing farthest from the monitor can be used for external
devices. Set the termination switch to non-terminated ( ) for all module housings and then terminate the
external device.

91369 Service Manual 2-12

Setup

Module Tests

To verify that the monitor functions correctly with parameter modules:

1 Insert an ECG module without the patient cables connected. Verify that the ECG parameter key is

displayed.

2 Connect a patient simulator to the ECG input with a 5-lead patient cable, and set the simulator to a known

rate.

• Verify that the heart rate and lead being monitored are displayed to the right of the ECG parameter

key.

• Verify that the ECG waveform is displayed.

3 Disconnect the patient cable. After 10 seconds, verify that the LEADS OFF message appears, the

parameter key flashes, and an alarm tone sounds.

4 Reconnect the patient cable and verify that the LEADS OFF message clears and the alarm stops.

5 Connect a patient simulator to the invasive pressure inputs.

6 Zero the pressures and verify that the numerics and waveforms are accurate.

7 Verify that the key tone sounds each time a key is selected.

Configuring the Monitor

The Biomed Level menu displays when the biomed password (default is biomed) is entered into the

Privileged Access window. Refer to Directory of Keys on page 7-1 for the Biomed Level menu structure.

Network Setup

Note:

The NETWORK SETUP key only displays on monitors that are configured for network operation.

Touch NETWORK SETUP to display the Monitor Setup - Network Configuration window. This window
contains an on-screen keyboard and three tabs: TCP/IP, Monitor, and Printers. Proper network operation
requires that each device on the network have a unique network address, monitor ID, and monitor name. If the
wireless option has been installed on the monitor, three more tabs will be present: WLAN, Security, and

Advanced.

Editing Tab Fields

The fields within a tab on the Monitor Setup - Network Configuration window can be edited by selecting the
field and entering new information using the on-screen or optional external keyboard.

When editing, adding, or deleting, press ENTER or TAB to cycle to the next input cell. Any changed or added
items are stored in the monitor’s non-volatile memory when SAVE is selected. The description of each tab
indicates when that change takes effect (for example, immediately or after a monitor reset occurs).

To edit text within a tab:

1 Select an item from the list.

-OR-

• Select the input cell and type the new information.

To delete an item from a list:

1 Select the item.

2 Touch Del.

3 Enter at least one space (an error message is displayed if no spaces are entered).

TCP/IP Tab

Figure 2-10: TCP/IP tab

The TCP/IP tab enables you to define the monitor’s attributes for networking.

IP Address — Enables you to specify the monitor’s IP address. The default is 164.90.254.10. Either a static IP

address must be specified, or DHCP networking must be enabled.

Subnet Mask — Enables you to identify which parts of the IP address are to be used for TCP/IP subnet
determination. The TCP/IP network’s subnet mask is not related to the Spacelabs Medical network’s subnet
name. The standard and factory-default subnet mask is 255.255.255.0. Either a subnet mask must be
specified, or DHCP networking must be enabled.

Gateway Address — Enables you to specify the IP address of the TCP/IP gateway (bridge or router) though
which communication to other devices should flow. The default is blank.

DHCP — (Dynamic Host Configuration Protocol) Used to configure and enable DHCP network configuration.
When DHCP is enabled, IP Address, Subnet Mask, and Gateway Address are automatically filled in. To use
this service, a DHCP server must be available on the network to respond to DHCP requests.

91369 Service Manual 2-14

Setup

Note:

• A DHCP lease is a TCP/IP configuration given out from the DHCP server that is valid for a period

defined by the DHCP server or forever (no expiration).

• Monitors configured for DHCP operation request a lease from the DHCP server when they boot up or

when their existing lease expires during operation. If the DHCP server is not present, the monitor
checks the expiration time of the last DHCP lease obtained. If the lease is still valid, the monitor
continues to use those values and operates normally. If the lease has expired, the monitor disables
TCP/IP networking and displays a NETWORK SIGNAL LOST message to indicate that it is unable to
communicate over the network. The monitor continues to request a DHCP lease until it receives one.

• If the monitor’s configured DECNET node ID is a duplicate on the network, the DHCP server can be

confused. This may result in a duplicate or invalid DHCP lease and may prevent full network
communication.

• The subnet mask must correctly correspond to the network size and type during operation. Monitors

may not be able to fully communicate with each other if the DHCP server fails to set the network mask
properly.

The DNS server address is in standard TCP/IP address form, while the DNS default domain is a string of
ASCII characters. A DHCP server may also provide this information.

Editing this tab is performed as described in Editing Tab Fields on page 2-13. Tabbing order is IP Address >>

Subnet Mask >> Gateway Address >> DHCP >> DNS Server Address >> DNS Default Domain >> IP
Address. Changes made to this tab’s settings take effect after a successful save and monitor reset.

Secondary Display — The Secondary Display field is only available if option -D, Perioperative, has been

activated.

Select ENABLE on the TCP/IP tab to activate the primary monitor’s secondary display. When you enable the
secondary display, the IP Address and Secondary Hostname fields become available and must contain a
valid entry for the secondary monitor to operate. The IP Address and Secondary Hostname fields are
exclusive to each other.

Enter a valid IP Address when your network is using static IP addresses.

-OR-

Enter a valid Secondary DNS hostname when your network is using DHCP for network configuration.

Changes made to the Secondary Display settings take effect after the changes have been saved.

91369 Service Manual 2-15

Monitor Tab

Setup

Figure 2-11: Monitor tab

The Monitor tab enables you to determine what monitor names, monitor (node) IDs, and subnet names are
currently in use. The tab also enables you to enter settings for the monitoring network.

In Figure 2-11, the monitor’s current settings are displayed in each input cell. The scroll list below each input
cell displays the remaining items that have been detected on the network. Items in the Subnet Name and
Monitor Name lists are displayed in alphanumeric order. Items in the Monitor ID list are displayed in numeric
order.

Brackets (< >) surround strings that consist solely of spaces. The separation within the brackets indicates the
number of spaces within that string.

Editing is performed as described in Editing Tab Fields on page 2-13. The tabbing order is Subnet Name >>
Monitor Name >> Monitor ID >> DECNET/IP >> Network >> TTL >> Subnet Name. Network and TTL are
skipped if unavailable. Changes made to this tab’s settings take effect after a successful save and monitor
reset.

Subnet Name

The subnet name contains up to five characters (default is five blanks). Items in this scroll list are selectable.

Monitor Name and Monitor ID

The Monitor Name is the name given to each bedside and central monitor (does not apply to telemetry bed
names) to help the users identify monitors on the network. The Monitor Name contains five characters (default
is SL001).

The Monitor ID is the numeric ID assigned to a monitor. Each device on the network must have a unique
Monitor ID. This can be any number from 1 to 1023, depending on the Network Size selected.

91369 Service Manual 2-16

Setup

To prevent duplication of currently used monitor names and IDs, items in these lists are not selectable. The
error checking procedure performed when SAVE is selected also specifically checks for duplications.

Note:

• Items in the Monitor Name and Monitor ID lists only display when the monitor is connected to the

network.

• When entering a monitor name or ID, do not use a space between characters.

DECNET/IP

You can configure the monitor to operate using either Spacelabs DECNET or TCP/IP network protocols. If you
are communicating with 903xx Spacelabs Medical monitors, you must select DECNET.

Network

The IP multicast group number of the monitor provides a filter to logically isolate one monitor from another on
TCP/IP installations. Up to 32 network numbers are available (0 to 31) with 0 as the default.

Note:

• Monitors must use the same network number to communicate.

• This is unavailable if DECNET is selected.

TTL (Time to Live)

The allowed number of hops the IP packet can take across network devices. TTL values are 1 to 64, with 16 as
the default.

Note:

TTL is unavailable if DECNET is selected.

Network Size

The network size allows configuration as:

64 — Monitor IDs from 1 to 64 are supported. No more than 64 total monitor devices can be on the

network. Provides complete network compatibility with legacy Spacelabs Medical monitors.

250 — Monitor IDs from 1 to 250 are supported.

Note:

903xx monitors must have the Expanded Network option installed or they will not communicate correctly
with devices with Monitor IDs above 64.

640 — Monitor IDs from 1 to 127 and from 512 to 1023 are supported with the following restrictions.

• All model 903xx Spacelabs Medical monitors must use monitor IDs 1 to 127, inclusive.

• All model 91xxx monitors must be configured with monitor IDs from 512 to 1023, inclusive.

1000 — Monitor IDs from 1 to 1023 are supported (compatible only with Spacelabs Medical 91xxx series
monitors).

91369 Service Manual 2-17

Setup

Printers Tab

The Printers tab enables you to display controls for defining and storing printer names, choosing rules for
printer selection, and selecting one or two network printers.

Figure 2-12: Printers tab

Editing is performed as described in Editing Tab Fields on page 2-13. The tabbing order is AUTO / PRIM/
BACKUP >> Printer A (or Primary) >> Printer B (or Backup) >> Printer Names (refer to Figure 2-13 on

page 2-19). Changes made to this tab’s settings take effect after a successful save and monitor reset.

Printer Names

The Printer Names list displays up to eight, selectable printer names previously stored in the monitor, in the
order in which they were stored. To display a new or changed name in the list, select that printer name from the
list. Printer names contain up to five characters (default is five blanks).

Note:

• Printer names are explicitly entered and may be duplicated. To clear a printer name from the list, select

that name, touch Clear, touch Enter, and then touch SAVE.

• A local (SDLC) printer can be either a bedside printer or network printer, depending on the printer name

selected in this list. A local printer is configured as a network printer if the local monitor’s name is
selected. Otherwise, a local printer functions as the bedside printer.

91369 Service Manual 2-18

Setup

AUTO / PRIM/BACKUP

The AUTO / PRIM/BACKUP key selects which set of printer selection rules the monitor uses for selecting
network printers. It does not affect the monitor’s selection of whether a networked or non-networked printer is
used. Any changes made to the printer selection mode using this key take effect immediately, regardless of
monitor type. The default setting is AUTO, which selects the destination printer using the weight-based printer
selection rules. (Refer to the Ultraview SL Operations Manual, P/N 070-1150-xx, located on CD-ROM
P/N 084-1101-xx for additional information).

When PRIM/BACKUP is selected, the monitor automatically selects the primary printer, unless that printer is
unable to accept the recording. In that instance, the monitor then selects the backup printer. If the backup
printer is also unable to accept the recording, the monitor displays an Unable to record message.

Printer Selection Fields

The default for the printer selection fields is blank (i.e., no printer selected). The labels above these fields vary,
based on the current setting of the AUTO / PRIM/BACKUP key. If AUTO is selected, the labels are Printer A
and Printer B. If PRIM/BACKUP is selected, the labels are Primary and Backup (Figure 2-13).

Figure 2-13: AUTO / PRIM/BACKUP selection differences

To define a printer name:

1 Select a printer name from the Printer Names list.

2 Select one of the two printer selection fields. The new value displays in the selected field.

WLAN Tab

This tab allows the operator to set basic wireless local area network (WLAN) related settings.

The WLAN tab only displays on monitors that are configured for wireless operation (option -Z). Monitors are
configured for wireless operation by selecting the sysgen RADIO option. The RADIO ON/OFF keys and all
other input cells and combo boxes illustrated in Figure 2-14 are not available for selection if the radio is not
present.

Caution:

Do NOT power the radio ON until all network configuration has been completed. Powering the radio
ON with the monitor set to the factory defaults could interfere with the wireless network.

91369 Service Manual 2-19

Setup

Figure 2-14: WLAN tab

The tabbing order is RADIO ON/OFF >> SSID >> Region >> Outbound Parameters >> Wireless DHCP >>
WLAN IP Address >> WLAN Subnet Mask >> Gateway Address >> RADIO ON/OFF. WLAN IP Address,
WLAN Subnet Mask, and Gateway Address are not available in the tabbing order if Wireless DHCP is

selected. Changes made to this tab’s settings take effect after a successful save and monitor reset.

RADIO ON/OFF (default = OFF)

The RADIO ON/OFF setting defaults to OFF when a radio is present. If this key is toggled to ON, and SAVE is
selected without a valid region defined [refer to Region (default = blank) on page 2-22], an error box displays
(the radio cannot be switched to ON if the Region setting is invalid). Select OK to remove the error box. The
RADIO ON/OFF key automatically toggles back to OFF.

The radio will function only if this key is set to ON. Keys, input cells, select boxes, and combo boxes are
enabled without regard to the setting of this key. However, WLAN communication only occurs if ON is selected.

Note:

Any change in the wireless tabs (except for the setting of the OUTBOUND PARAMETERS input cell)
requires a monitor reset before the changes take effect.

To activate the radio-only functions, select ON.

Wireless DHCP (default = OFF)

The Wireless DHCP tab is similar in function to the DHCP key on the TCP/IP tab, but for wireless networks.
When Wireless DHCP is selected, the monitor asks the wireless DHCP server for the following information:

• WLAN IP Address

• WLAN Subnet Mask

• Gateway Address

91369 Service Manual 2-20

Setup

The affected input cells then display the values provided by the wireless DHCP server, rather than the values
from the monitor’s non-volatile memory. These cells then become unavailable for selection, to prevent these
values from being changed, until Wireless DHCP is de-selected.

If Wireless DHCP is selected, as in Figure 2-14 on page 2-20, DNS Server Address and DNS Default
Domain values display, and the WLAN IP Address, Wireless Subnet Mask, and Gateway Address input
cells are unavailable for selection.

When Wireless DHCP is not selected, the DNS Server Address and DNS Default Domain values disappear,
and the WLAN IP Address, Wireless Subnet Mask, and Gateway Address input cells are available.
