1 General Introduction

1.1 The Heidelberg Retina Camera

The Heidelberg Retina Camera (HRC) is a scanning digital
opthalmoscope for the examination of the anterior and the posterior­segment of the eye with or without contrast or fluorescence agent. The
resulting images aid the physician in the diagnosis and the follow up of
various diseases of the anterior and the posterior-segment of the eye.

1.2 Safety Information: Cautions and Warnings

Please read this section carefully and always follow its contents!

1.2.1 General Safety Information

WARNING The light emitted from this instrument is potentially hazardous. The

longer the duration of exposure, the greater the risk of ocular damage.
Exposure to light from this instrument when operated at maximum
intensity will exceed the safety guideline after 30 minutes.

IMPORTANT Before you start working with the instrument, make sure that you know the

correct procedures for turning the instrument on and off (Chapter 5).

2 Electrical System Configuration

The HRC together with the connected computer and other connected devices constitutes a
medical electrical system (ME-system) according to IEC 60601-1-1. This system must meet
specific safety criteria as detailed in the standards and in this document.

connected device will become part of the ME-system, even if the only connection is the
power supply cord leading to a shared multiple socket outlet.

Example: The HRC is connected to a laptop computer, the laptop computer is connected to
a printer (via USB or WLAN). All devices are connected to the main power supply using a
multiple socket outlet. An electrical table is also connected to the same multiple socket
outlet. In this case, the “ME-system” consists of all devices: HRC, laptop, printer and table.

The basic principle when setting up a ME-system is that the overall safety of the system
inside the patient environment is comparable to the safety of a single medical device. To
ensure this, nonmedical devices that are part of the system must conform to their
respective IEC or ISO standards (e. g. IEC 60950) and additionally must conform to the
leakage current limits of the 60601-standard for medical devices.

Caution: Use isolation transformer conforming to IEC 60601-1.

the database folder and a path to the patient folder
must be entered.

HRC Installation Instructions Vers. 001 29

For a network installation, the database and the patient
folder on the server PC must be shared to allow
unrestricted file access for client PCs. There are two
ways to enter the server’s database and patient folder on
the client computer:

Map the shared database folder of the server PC to a
local drive (e.g. drive letter ‘J’). Use the “Browse” button
to navigate to the shared database folder on that
mapped local drive (e.g. J:) and select it.

Enter the UNC path of the shared database and patient
folders. A UNC path begins with a double backslash and
consists of the following elements:

\\SERVER_NAME\SHARE_NAME\PATH

The usage of UNC network path specification is highly
recommended, because a mapping of the shared file
resources on the client PCs is not required. In addition,
drive mapping can be easily lost if the client PC will be
started before the server PC is running. Another
problem with mapped network drives is that the drive
letter may change if an additional disk device (e.g. Zip­drive) is temporarily attached.

Click “Next” to continue the installation.

Workstation ID (Network Client only)

A unique workstation ID is required for every client PC.
Start numbering the clients with 2 and increment this
value by 1 for every new client installation. The
number of workstations, which can run at the same
time, depends on the number of licenses purchased.
The workstation ID must never exceed the number of
licenses.

Click “Next” to continue the installation.

Workstation Name (Network Client only)

Enter a unique workstation name for every client
installation.

Click “Next” to continue the installation.

6.4 Software Settings

The COM port setting for the footswitch connection in the hrc.ini file has to match the
COM port indicated in the Windows Device Manager. Otherwise the HEYEX software will
not find the footswitch when opening the acquisition window.

The COM port default setting in the hrc.ini file is COM1.

Please check the COM port setting in the device manager upon installation. If it does not
match the setting in the hrc.ini file, change the setting in the hrc.ini accordingly (see red
circles in figure 3 and 4 below).

The USB-serial adapter has to stay connected to the same USB port for the system to
operate.
