1. General information
1.1 ESD
CAUTION
!
This equipment includes parts and assemblies sensitive to damage from electrostatic discharge. 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
•Costly repair
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 guidelines.
• 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.

• 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 workstation.
• Use protective packaging when you transport components from one area to another.
Transparent antistatic bags, available from a variety of manufacturers, shield the components 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 terminal before soldering.

2. Physical connection
On the back of the Network ID Camera there are four connectors for communication.
2 AUX 1 HOST NET
2.1 The HOST connector
This connector is a female 9-pin DB9 connector. Its pinout is designed with the 9-pin connector 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. .
Name Direction No
DCD Out 1
RxD Out 2
TxD In 3
DTR In 4
GND 5
DSR Out 6
RTS In 7
CTS Out 8
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. .

2.3 The NET Connector
This connector carries one RS422/485 (software selectable) and one RS485-only communication 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 connector 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 materials made for 10Base-T networks. Below follows the specification of the NET connector that
may be needed if other material is used.
The pinout of the NET connector.

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.
