1. General information
1.1 ESD
This equipment includes parts and assemblies sensitive to damage from electrostatic dis-
charge. Use caution to prevent damage during all service procedures..
1.1.1 Overview
Electrostatic discharge (ESD) is a primary source of
• Product downtime
• Lost productivity
•Costlyrepair
While we cannot feel a static charge of less than 3,500 volts, as few as 30 volts can damage
or destroy essential component in the electronic equipment. As technology advance, these
components will be even more vulnerable to ESD destruction.
Therefore, to maintain and increase productivity and profitability, you must observe ESD
guidelines.
Effective ESD control requires the following things.
1.1.2 Awareness
Everyone in your organization should be aware of ESD because partial ESD control is no
ESD control at all.
Everyone needs to remember that:
• ESD is a primary source of equipment failures and intermittent malfunctions.
• ESD affects productivity and profitability
• ESD can be controlled
1.1.3 Action
Everyone from senior management to be evening security crew must observe ESD guide-
lines.
• If you repair and maintain electronic equipment, always wear grounding straps and work
at ESD protected sites.
• If you work around electronic equipment, keep static generators like plastic trash bags
away from sensitive components.
• Observe ESD guidelines every day. (See the following sections for special tips).
• Remember, effective ESD control is everyone's responsibility.
1.1.4 Every day
• Keep trash away from static-sensitive equipment. Plastic materials, such as plastic foam
cups, generate the static electricity that damages or destroys electronic components.
• Look at the label. Static-sensitive components are marked with bright graphic labels.
Follow the label directions.
CAUTION
!

• Spray the carpet. ESD that is generated when you walk over carpet is a major cause of
component destruction. In some cases, especially in low-humidity environments, you
may need to periodically spray the carpets with an anti static spray that is available at
local stores.
1.1.5 During maintenance
• Wear a ground strap when you work with static-sensitive components. Always make
certain that the clip is attached to a properly grounded, unpainted surface.
• Use a portable ground mat if you cannot repair components at an ESD protected work-
station.
• Use protective packaging when you transport components from one area to another.
Transparent antistatic bags, available from a variety of manufacturers, shield the com-
ponents from future damage.
1.2 Safety precautions
• Do not operate or repair the ID camera without proper accessories. Add all COVERS
before use to prevent mechanical hazards and electrical shock.
• Do not use a damaged POWER CORD. The damaged CORD can cause malfunctions
and current leakage or electrical shock.
• If there are any abnormal smell or smoke during operation, de-energize the ID camera
immediately and contact authorized personnel for support.
• Do not operate the ID camera in unsafe locations such as outdoors or in wet places. Do
not allow liquids, gaseous or solid-state materials to enter the ID camera.
• When doing electrical measurements, use an isolation transformer or leakage current
detector in the power line to avoid an electrical shock.
• Double pole/neutral fusing. For continued protection against risk of fire, replace only
with same type and rating of fuse.
• Use only original parts from the Parts List to repair the ID camera.
Make sure that the requirements of UL 122 - Splice and Connection - paragraph 13.10
and EN 60 950, section 4.39 are observed. When replacing AC primary components,
such as wires, sockets or capacitors, wrap the end of the wire completely around the ter-
minal before soldering.

2. Physical connection
On the back of the Network ID Camera there are four connectors for communication.
2.1 The HOST connector
This connector is a female 9-pin DB9 connector. Its pinout is designed with the 9-pin con-
nector used on PC compatibles in mind. If the Network ID Camera is to be connected to a
PC compatible computer a pin-to-pin cable with a male connector on one end and a female
connector on the other end can be used. If it will be connected to another host computer the
following pin description can be used to make your own cable. Note that the name of the
pins mentioned is what the pin should be connected to. Thus RxD is really an output from
the camera. .
Note that the Network ID Camera do not need any handshake signals to work. It sends out
all handshake signals to the host computer but ignores any handshake input. If your host
computer also ignores the handshake signals you will only need to connect the ground (pin
5) and the TxD (pin 3).
2.2 The AUX connectors
These connectors are of type RJ12 connectors. Note that the name of the pins mentioned
is what the pin should be connected to. Thus RxD is really an output from the camera. .
+VDC is a high level signal out. This signal is intended for setting DCD and DSR if needed.

To adapt the AUX connentors to 9 pin DB9 PC compatible RS232 interface a adapter cable
is required
2.3 The NET Connector
This connector carries one RS422/485 (software selectable) and one RS485-only commu-
nication channel. When using this connector for patient data download only the RS422/485
channel is used in RS422 mode. This channel is called the HOST-RS422 below.
The connector is of the type RJ-45. It was selected because there are a lot of cable and con-
nector material available for this kind of connector as it is also used to build LAN networks
of type 10Base-T for personal computers. Normally this way is used to connect cameras to
a host computer is when one host computer is connected to more then one camera but it
may also be used if the distance between the host computer and camera is too long for
RS232.
Next section will describe how to build an RS422 network using commonly available mate-
rials made for 10Base-T networks. Below follows the specification of the NET connector that
may be needed if other material is used.

Regardless of what is connected where, shielded connectors, patch cables and installation
cables should be used. The cable should be a "4 pair STP" category 3 or 5. Unfortunately
there does not seem to be any standard name for this equipment that can be referred to
when buying. The only common description seems to be that it is the same equipment as is
used for 10Base-T networks.

3.2.3 Switch On / Initialize Procedure
Camera status: Mechanic position of the
carriage is not known. Cam-
era is energized.
The microprocessor starts the initialization
routine. First while still executing the boot-
strap program, the P key is checked. If
pressed the download procedure will be start-
ed.
If not pressed the bootstrap routine will call
the main program.
The main program initializes all hardware re-
sources on the CPU board as well as the op-
erator- and exposure display.
The main program checks if the set-up mem-
ory is valid by calculating a check sum. If the
check sum does not match the stored value
the set-up memory is erased.
The opening unit is run to calibrate the mech-
anism to find out the left position of the move-
ment area.
The contrast of the exposure display is set.
If calibration of opening mechanism as well as
for contrast of exposure display is successful
the main picture is displayed and the camera
is ready for operation.

Camera status: The opening carriage is positioned in its
left position.
The sequence is initialized when the left and right cassette
sensors are activated while the middle sensor is not.
First the motor is run to the right at a slow speed until the
finger of the carriage has entered the hole of the cassette
lid and unlocked the lid. At that point the speed of the motor
is increased to full speed.
The motor is run at full speed until the position where the lid
is considered opened. At this position the motor is stopped.
This position can be changed in the setup of the camera.
The exposure is made by switching on the background light
of the exposure display. When the exposure is done the
background light is switched off.
The motor is now run at full speed towards it's left position
until position 10 is reached. At that position the operator
display starts flashing and the speed is slowed down, The
motor run until no movement is detected for 0.3 seconds.
The motor is now considered being stopped at its left posi-
tion. The position is now checked. If it is not within -3 to 3 it
was not able to reach its left parking position and an error
message is generated. If within this range the position is set
to 0 and the exposure cycle is finished.
The right and left sensor must both be off before the oper-
ator display stops flashing and a new exposure can be
made.
During all operations it is checked that the motor is rotating.
If no pulses are read from the pulse counter for 0.3s the mo-
tor is considered stopped by force and the motor is
switched off and an error message generated.

3.2.5 Keyboard
The keyboard is a standard 84 keyboard.
The keyboard layout may be changed by replacing the whole keyboard and selecting the
appropriate language in the firmware.
3.2.6 Operator display.
The operator display is a 240 pixel wide and 64 pixel high graphic liquid crystal display (LCD)
display with cold cathode fluorescent lamp back-light. The LCD is controlled by the micro-
processor on the CPU board. All characters are generated by the microprocessor and this
allows the Network ID Camera to show any character on the display in any size. Current
firmware provides 256 - 32 characters according to ISO 8859-1 in three sizes.
The back-light is driven by a high voltage and the generator (called inverter) that is located
as a small separate board on the CPU board. The life-length of the back-light is between
10,000 and 15,000 hours. Life-length is the number of hours the light can be on until the in-
tensity has decreased to half of the initial intensity. To extend the life length of the back-light
it will be switched off automatically when the camera has not been used for an hour and will
be switched on again as soon as a key on the keyboard is hit.
The LCD display is protected by a acrylic shield that can be replaced separately. It is not a
part of the LCD display but inserted between the LCD unit and the case.
3.2.7 Exposure unit.
The main parts of the exposure unit are the display, the lens and a mirror
The display is used to generate the picture that will be printed on the film. It is a 240 pixel
wide and 64 pixel high graphic liquid crystal display (LCD) display with cold cathode fluores-
cent lamp back-light, same type as the operator display. It is fully graphical which means
that any picture can be generated, the picture can be mirrored in any direction and the in-
formation can be printed either white on black or black on white.
The lens is a specially made for this camera. Both the sides of it has a convex lens and the
least convex side should face the display. The size of the picture on the film can be adjusted
by moving the lens backwards or forwards. This is though not recommended except in spe-
cial cases. On the market there are very few cassettes with a window which is shorter then
normal. For example there exists a mammography cassette where the window is located on
the short side and not on the long which is normal. Because of this there is no room to open
the window fully, instead the window is made about 25% shorter. To be able to use this cas-
sette with the Network ID Camera the lens has to be moved. It may also be necessary to put

September 2003 14 Triacon AB Sweden
the lens backwards to decrease the size of the picture even more. When shipped the size
and position of the picture is set to work with Kodak cassettes or equivalent.
The mirror is a surface plated mirror. It should not be polished as this will destroy the silver
layer and affect the quality of the picture. The mirror can be moved backwards and forwards
and tilted. It is important to set the angle correct as if the angle is not 45 degrees the picture
will be a trapezoid instead of a rectangle.
3.2.8 Opening mechanism
The opening mechanism consists of a motor driving a screw. This screws drives a carriage
which glides on a shaft. The carriage has a finger that unlocks the lid and opens the lid. To
do this the finger has to move up and down and this is achieved by a cam on the back of the
opening mechanism assembly and a ball-bearing mounted on the back of the carriage which
rolls on this cam. On the left side of the opening mechanism assembly there is a code disk
mounted on the driving screw and a optical switch which is used as a pulse counter.
The opening sequence is described in chapter 2.2.3 and will not be repeated here.
The optical board mounted on the left side of the assembly can be sledded backwards and
forwards to adjust the cassette sensing point. This adjustment is described in the Diagnostic
chapter. There is no need for any adjustment for the pulse counter.
The only adjustment on the opening mechanism is the position on the cam. The cam can be
sledded sidewise to adjust the position when the finger goes down in the lid to unlock it. If
this position is set too far to the right the lid may not lock when closing the lid. If the position
is set too far to the left the finger may hit the edge of the window. When doing the adjustment
it is a good idea to gently press the finger down to get the play in its down position and then
move the carriage manually by rotating the screw. Also the setting should be checked with
all cassette types used. When the setting is correct, rotate the screw by hand through the
phase where the finger goes down and while doing so, push the finger gently upwards to get
the play in the upper position. This should be done to check that the carriage can in no way
hit the exposure unit.
In the finger there is a pin. There are two kinds of lids on the cassette types the Network ID
Camera can work with. One is made of metal with a metal locking mechanism. This lid is
used on all or many of Kodak's, Fuji's and Dupont's cassettes. The other is made of plastic
with a plastic locking mechanism. The plastic lid is more then 1mm thicker then the metal lid
which means that the finger has to reach 1mm deeper when the plastic lid is used. The
strength of the spring is such that when the metal lid with its metal locking mechanism the
locking mechanism will be able to push the pin upwards but when the plastic lid is used with
