Safety information for users
Handling of
electrostatically
sensitive modules
Shipping of
modules
ADAM modules make use of highly integrated components in MOStechnology. These components are extremely sensitive to over-voltages
that may occur during electrostatic discharges.
The following symbol is attached to modules that can be destroyed by
electrostatic discharges:
The symbol is located on the module, the module rack or on packing
material and it indicates the presence of electrostatically sensitive
equipment.
It is possible that electrostatically sensitive equipment is destroyed by
energies and voltages that are far less than the human threshold of
perception. These voltages may occur where persons do not discharge
themselves before handling electrostatically sensitive modules and they
may damage components thereby causing the module to become
inoperable or unusable. Modules that have been damaged by electrostatic
discharge are usually not detected immediately. The respective failure may
become apparent after a period of operation.
Components damaged by electrostatic discharges can fail after a
temperature change, mechanical shock or changes in the electrical load.
Only the consistent implementation of protective devices and meticulous
attention to the applicable rules and regulations for handling the respective
equipment is able to prevent failures of electrostatically sensitive modules.
Please ship the modules exclusively in the original packing material.
Measurements
and alterations on
electrostatically
sensitive modules
1-2 ADAM 8000 Manual CPU 821x – Rev 1.1
When you are conducting measurements on electrostatically sensitive
modules you should take the following precautions:
• Floating instruments must be discharged before use.
• Instruments must be grounded.
You should only use soldering irons with grounded tips when you are
making modifications on electrostatically sensitive modules.
Attention!
Personnel and instruments should be grounded when working on
electrostatically sensitive modules.

Hints for the deployment of the MPI interface
2
What is MP
I?
Deployment as
MP interface
The MP
2
I jack combines 2 interfaces in 1:
• MP interface
• RS232 interface
Please regard that the RS232 functionality is only available by using the
Green Cable from Advantech.
The MP interface provides the data transfer between CPUs and PCs. In a
bus communication you may transfer programs and data between the
CPUs interconnected via MPI.
Connecting a common MPI cable, the MPI jack supports the full MPI
functionality.
Important notes for the deployment of MPI cables!
Deploying MPI cables at the ADAM CPUs from Advantech, you have to
make sure that Pin 1 is not connected. This may cause transfer problems
and in some cases damage the CPU!
Especially Profibus cables from Siemens, like e.g. the 6XV1 830-1CH30,
must not be deployed at MP
2
I jack.
For damages caused by nonobservance of these notes and at improper
deployment, ADAM does not take liability!
Deployment as
RS232 interface only
via "Green Cable"
For the serial data transfer from your PC, you normally need a MPI
transducer. Fortunately you may also use the "Green Cable" from
Advantech You can order this under the order no. ADAM-8950-0KB00.
The "Green Cable" supports a serial point-to-point connection for data
transfer via the MP
2
I jack exclusively for ADAM 8xxx CPUs.
Please regard the hints for the deployment of the "Green Cable" on the
following page.

Hints for the deployment of the Green Cable
What is the
Green Cable?
The Green Cable is a green connection cable, manufactured exclusively for
the deployment at ADAM System components.
The Green Cable is a programming and download cable for ADM CPUs
8xxx and ADAM fieldbus masters. The Green Cable from Advantech is
available under the order no. ADAM-8950-0KB00.
The Green Cable allows you to:
• transfer projects serial
Avoiding high hardware needs (MPI transducer, etc.) you may realize a
serial point-to-point connection via the Green Cable and the MP
This allows you to connect components to your ADAM CPU that are able
to communicate serial via an MPI adapter like e.g. a visualization
system.
• execute firmware updates of the CPUs and fieldbus masters
Via the Green Cable and an upload application you may update the
firmware of all recent CPUs 8xxx and certain fieldbus masters (see
Note).
Important notes for the deployment of the Green Cable
Nonobservance of the following notes may cause damages on system
components.
For damages caused by nonobservance of the following notes and at
improper deployment, Advantech does not take liability!

I jack.
Note to the application area
The Green Cable may exclusively deployed directly
1-4 ADAM 8000 Manual CPU 821x – Rev 1.1
of the ADAM components (in between plugs are not permitted).
At this time, the following components support the Green Cable:
CPUs 8xxx and the fieldbus masters ADAM 8208-1xx01 from Advantech.
Note to the lengthening
The lengthening of the Green Cable with another Green Cable res. The
combination with further MPI cables is not permitted and causes damages
of the connected components!
The Green Cable may only be lengthened with a 1:1 cable (all 9 Pins are
connected 1:1).

Overview System 82xx
The System 82xx
The System 82xx is a modular automation system for low and middle range
of performance that you may use either centralized or decentralized. The
single modules are directly clipped to a 35mm DIN rail and are connected
together with the help of special bus clips.
The following picture shows the range of performance of the System82xx:
