Configuration Page 2

Flash Size

Flash Size indicates the ECG storage capacity of your electrocardiograph. Normal Flash Size is the standard
memory capacity. If the optional expanded memory has been installed, Expanded will be displayed.

ID Format

This option defines the format for the patient ID information prompts. There are three standard formats: short,
standard, or long. A custom ID format is optional when downloaded from the E-Scribe Data Management System.

The short format includes the patient's last name and first name, patient ID number, date of birth, which will
automatically calculate the age, and gender field.

The standard format includes the patient's last name, patient ID number, age, height, weight, gender, race,
medication 1, medication 2, and a location field.

The long format is identical to the standard format except that it includes the patient's first name, room and comment
fields.

The custom format, which is designed in the Mortara E-Scribe Data Management System, can be downloaded to the
ELI 150. The custom ID format is uniquely designed to meet your facility’s needs. Please see Appendix A to
download a Custom ID.

Auto-Fill ID

When enabled, the system will automatically populate the demographic fields in the ID screen. When the patient ID
field is manually populated and followed either by selecting enter or F2 (▼) the system automatically scans the
patient directory and if records with the exact ID are found, the existing data is used to fill some of the demographic
fields. The auto-fill feature is designed to only automatically populate last name, first name, date of birth, age and
gender. If no matching records are found, a brief message is displayed and the user must manually enter the
patient’s demographics.

NOTE: In order to avoid the use of incorrect data, the Auto-Fill ID feature is only supported if the ID
formats are the same between records.

AC Filter

ELI 150

3-10

The ELI 150 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your
country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that the
proper AC filter is selected.

Paper Speed

The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm printouts and
display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for display or rhythm
printing. Paper speed is printed at the bottom-right corner of the ECG printout.

Filter

The ECG plot frequency filter (or print filter) can be set to 40Hz, 150Hz, or 300Hz. The plot frequency filter does
not filter the acquired digital record. A 40Hz plot filter setting will reduce the noise (40Hz and higher frequencies)
on the printed ECG, a 150Hz plot filter setting will reduce the noise (150Hz and higher frequencies) on the printout
and a 300Hz plot filter setting will not filter the printed ECG. The filter setting is printed at the bottom right corner
of the ECG printout.

Height/Weight Units

This option defines the units of weight and height to either pounds/inches (lb/in) or kilograms/centimeters (kg/cm).

Date Format

This option defines the format for entering and displaying the patient’s date of birth in either the U.S. format or the
European format.

For example: July 16th, 2003 is displayed as follows:
US Date Format: MM/DD/YYYY (07/16/2003)

European Date Format: DD.MM.YYYY (16.07.2003)

NOTE: the date format option does not modify the acquisition date printed on each ECG. Using the
example above, the acquisition date would print as 16-Jul-2003.

Interpretation Option

The ELI 150 automatically analyzes ECGs and prints the optional interpretation on the ECG printout. This option
allows you to select or suppress the “interpretive” text on the ECG report.

NOTE: A qualified physician should review the computer generated ECG interpretation before the
treatment of any patient.

Reasons

The reason statements indicate why a particular interpretive statement was printed. Reason statements print in
[square brackets] within the interpretive text (if the interpretation is turned on). Turning the reason statement
function on or off does not affect the measurements performed or the interpretive statements selected by the analysis
program.

For Example:
Anteroseptal Infarct [40+ MS Q WAVE IN V1-V4]
Where “Anteroseptal Infarct” is the interpretive statement.

Section 3

3-11

And “40+ MS Q WAVE IN V1-V4” is the reason statement or explanation as to why the
interpretive statement was printed.

Configuration Page 3

Append

A status or statement phrase can be appended to the ECG and printed under the interpretive text printout. Either

“unconfirmed report” or “reviewed by” can be selected. However, if you wish to have nothing appended to the

ECG, “blank” may be selected.

Number of Copies

This option defines the number of printed copies when an ECG is taken. A zero (0) setting prints the original only;
one (1) prints the original plus 1 copy; two (2) prints the original plus 2 copies, and so on. Up to 9 copies may be
selected.

ECGs Retrieved

This option defines the number of ECGs retrieved from an E-Scribe data management system. The ECGs are
retrieved by ID number. A zero (0) setting retrieves the most current ECG for that ID number. Settings from one

(1) to seven (7) retrieve the most current ECG plus “X” number of ECGs identified by the entered value.

EXAMPLE: If you enter the number 5, you will retrieve the most current ECG plus the five preceding ECGs for
that ID number. ECGs retrieved from the E-Scribe are only printed at the ELI250 and not saved.

Delete Rule

This option defines the ECG auto delete status in the patient directory. ECGs that are marked for deletion will be
automatically removed or erased based on its date (a first in/first out philosophy) to make room necessary for the
new ECG record. ECGs are only erased from the directory when they are marked for deletion and if the directory
becomes full. More than one ECG may be removed from the directory in order to make room for the the new
incoming record. The delete rule selections are:

Post Plot = ECG is automatically marked deleted after printing.

Post Transmit = ECG is automatically marked deleted after transmission.

ELI 150

3-12

Post Plot/Transmit = ECG is automatically marked deleted after transmission and printing.

Storage Sensitivity

The ECG storage sensitivity setting dictates the resolution of the stored record. The sensitivity settings are either
Normal or High. If the configuration value is set to High, the stored ECG will have a high resolution. As a result,
the records size will be large and will reduce the storage capacity in the ECG directory.

Auto Save ECG

This option defines whether or not the ELI 150 is to automatically save newly acquired ECGs in the directory, once
they are acquired and printed. If the auto save configuration option is set to NO, and the record is printed, the ELI
150 will prompt you to “Save ECG?” SAVE (F1) will store the ECG in the directory.

NOTE: manually save ECGs by selecting More (F5) from the Acquired ECG view and Save (F5).

Auto Print ECG

This option defines whether or not the ELI 150 will automatically print the ECG after acquisition. If the selected
configuration option is set to NO, a manual printout is possible after acquisition.

Baud Rate

The user-selectable baud rate determines the serial port’s data transmission rate in bits per second (bps). Set the
baud rate to: 9600, 19200, 38400, 57600, or 115200 bps for direct data transmission between the ELI 150 and
another Mortara cardiograph, and 38400 bps for a direct connection to the E-SCRIBE data management system.

the ELI 150. The rear section of the motherboard (located at what is the back of the unit when mounted in the
chassis) contains the power supply of the unit.

Power Supply

The AC power supply consists of the AC inlet connector, AC inlet fuses and a switching power supply. The
switching power supply automatically senses the input voltage coming in on the AC line and switches to supply the
proper voltage to the unit.

The AC power supply powers the unit for operation and charges the internal battery. When the unit is not connected
to an AC power source the internal battery will supply power to operate the unit.

Logic Circuitry

The logic circuitry or digital section of the mother board contains the microprocessor, FLASH memory, Real time
clock, LCD & keyboard control circuitry, interface circuitry for modem and RS232 communications, and the Writer
interface circuitry.

Writer Interface

The writer interface on the motherboard consists of 5 connectors. Two of the connectors/cables connect directly to
the thermal printhead of the writer. These two cables carry power, data and ground connections to the printhead.
The third cable of the writer interface is for motor control and carries power, ground and stepper signals to the
writer motor. The fourth cable is for the cue sensor and allows the motherboard to sensor when the paper is at the
correct position to start printing. The fifth cable is an additional grounding wire for the printhead.

Connectivity Options

The connectivity options for the ELI 150 are: Internal Modem, GSM Modem, External Modem, LAN and Direct
Connection. Each one of these options except Direct Connection and External Modem requires a circuit board to be
soldered to the motherboard of the ELI 150. Please see the appendices associated with the Connectivity options.

The ELI 150 has a 9-pin RS232 port. This port serves three functions. The first is it allows software to be
downloaded to the unit (the connectivity options are not required for this). The second, and most common, is for

transmitting ECG’s either to another unit or to a data management system (The connectivity option is required for

this form of transmission). The third function is for transmitting ECGs to either a data management system or
another electrocardiograph via an external modem (the connectivity option is required for this form of
transmission).

Keyboard and LCD interface

The keyboard and LCD interface consists of a large ribbon cable that connects from the motherboard to the
keyboard and LCD of the unit. This cable carries the data to the LCD and keyboard inputs to the motherboard.

Front End Board

The analog information from the patient enters the unit via the patient cable then enters the front end board. The
information is immediately digitized to create the 12 leads of ECG data. This digitized information is then sent to
the motherboard via an interconnect cable. This interconnect cable carries power and ground from the motherboard
to the front end and also caries serial clock and data from the front end to the motherboard. If the motherboard does
not receive the clock and data signals from the front end, the LCD will not display any ECG waveforms.

Writer Tests

From the main menu press and hold the following key combination Alt + Shift +RHY. The following test strip will
be printed.

Note: This test should be performed with the AC power connected to the unit.

Section 6

6-7

Description of printout

At the top of the writer test print out will be the printable characters of the writer.

The next section will have a 200-mm line. This line should be measured with a ruler and will indicate if there is a
writer motor problem if the line is too short or too long. The tolerance of this line is +/- 2-mm.

The next line that prints is an indication of the cue sensor. At the beginning of the printout there should be a dip
towards the bottom off the page and then it should move to a baseline level. When the cue mark is sensed for the
second page of the printout a second dip is printed. Note: there will be fluctuation in this line, this is normal. Look

for extreme variations that can indicate possible problems with the cue sensor or cue sensor circuitry.

The next line that prints is a zigzag line. Check to see that none of the dots are missing.

At the bottom of the page, starting in the lower left and continuing to the top of the page, two diagonal lines will be
printed. Check these lines for any missing dots. If dots are missing the print head may need to be cleaned or
replaced. Also check the lines for any “steps” which can indicate a motor problem.

Another item that is printed is a circle. Check the circle to make sure that there are no breaks or gaps in the printing.
This can indicate a problem with the writer motor and the thermal print head.

Near the end of the first page and continuing onto the second page will be two diagonal lines. Check these lines to
see if there are gaps. If there are gaps sections of the print head may be burned out. If this is the case the print head
should be replaced.

When printing an ECG at different paper speeds the calibration pulse printed at the beginning of each trace can be
used to check the paper speed. Check the calibration pulse by measuring the width and amplitude of the pulse at the
beginning of each line of ECG tracing. Use the following table for the correct measurements.

Note: The measurements should be made using a ruler and not the grid on the paper.

Connectivity options

Introduction

There are four connectivity options on the ELI 150. These options are Serial Connectivity, Modem Connectivity,
LAN Connectivity and GSM Modem Connectivity. Each option uses different hardware soldered to the ELI 150
motherboard except for the Serial Connectivity option.

For operation of the different types of connectivity options please refer to the ELI 150 Operator Manual.

RS232/Serial Connectivity Option

The Serial Connectivity option will allow the user to transmit and receive ECG information via the nine pin serial
port on the back of the ELI 150. The RS232/Serial Connectivity option is the only option that does not require a
modification to the motherboard of the ELI 150 but requires the connectivity option within the ELI 150 software be
installed.

To upgrade a unit to the Serial Connectivity option you will need to contact Mortara Instruments Technical Support
Group to obtain the software and the units serial number file.

Modem Connectivity Option

The Modem Connectivity option for the ELI 150 is soldered to the motherboard and is not field replaceable. If there
is a problem with the modem the motherboard of the unit will require replacement.
