Introduction
Introduction
1.1 Overview
The ADAM-5000 series is a complete product line that provides a wide
variety of features in a data acquisition and control application. It
includes 4 I/O-slots ADAM-5000/485 and 8 I/O-slots ADAM-5000E.
They are remotely controlled by the host computer through a set of
commands and transmitted in a RS-485 network. The system kernel is
small, but offers many good features to the users. The modular
design also provides more flexibility in the system configuration. The
following is a summary of the major ADAM-5000 system components.
ADAM-5000 System Kernel
The ADAM-5000/485 system kernel includes a CPU card, a power
regulator, a 4-slot base, a built-in RS-232 communication port and one
built-in RS-485 communication port. The 5000E system includes all of
the above components, except it has an 8-slot base. Details of the
system kernel features and more are covered in Chapter 3.
I/O Configuration
The ADAM-5000/485 CPU can support up to 64 I/O points with the 4slot base currently available.The ADAM-5000E CPU can support up to
128 I/O points with the 8-slot base currently available. These points
can be assigned as input or output points.
I/O Modules
The ADAM-5000 series has a complete range of I/O modules for your
applications. A full range of digital modules which support 10 to
30 VDC and relay outputs are offered. The analog modules provide
16-bit resolution and programmable input and output signal ranges
(including bipolar).
Software Utilities
There are some software utilities available to the ADAM-5000
systems. The DOS and Windows utility software helps you to
configure your ADAM-5000. The DLL (Dynamic Link Library) is
provided to write W indows applications, and the DDE (Dynamic Data
Exchange) server provides links to popular Windows packages such
as Intouch, FIX DMACS, Advantech GeniDAQ, etc.

Introduction
1.3 A Few Steps to a Successful System
Step 1: Review the Installation Guideline
You should always make safety your first priority in any system
application. Chapter 2 provides several guidelines that will help
provide a safer, more reliable system.
Step 2: Understand the System Kernel
The system module is the heart of ADAM-5000 system. Make sure
you take time to understand the various features and setup requirements.
Step 3: Understand the I/O System Configurations
It is important to understand how your I/O modules can be configured.
It is also important to understand how the system power budget is
calculated. This can affect your I/O configuration.
Step 4: Understand the Utility Software
Before you begin to link your applications in your host computer with
the ADAM-5000 systems, it is very helpful to understand how the
DOS and Windows utility software helps you configure your
ADAM-5000.
Step 5: Review the Programming Concepts
All control systems differ in some areas. The ADAM-5000 system
allows you to develop your applications in DOS or Windows. It
provides an ASCII command set, DLL (Dynamic Library Link) and DDE
(Dynamic Data Exchange) server to you.
Step 6: Understand the Troubleshooting Procedures
Many things can be happened on the factory floor: switches fail, the
power supply is incorrect, etc. In most cases, the majority of the
troubleshooting time is spent trying to locate the problems. The
ADAM-5000 system has some built-in features that help you quickly
identify problems.

2.1 General
Environmental Specifications
The following table lists the environmental specifications that generally apply to the ADAM-5000 system (System kernel and
I/O modules).
Specification Rating
Storage temperature -13 to 185°F (-25 to 85°C)
Ambient operating
temperature
Ambient humidity* 5 to 95%, non-condensing
Atmosphere No corrosive gases
14 to 158°F (-10 to 70°C)
* Equipment will operate below 30% humidity . However , static
electricity problems occur much more frequently at lower humidity
levels. Make sure you take adequate precautions before you touch
the equipment. Consider using ground straps, antistatic floor coverings, etc. if you use the equipment in low humidity environments.
Power Requirements
Although the ADAM-5000 systems are designed for standard
industrial unregulated 24 VDC power supply, they accept any power
unit that supplies within the range of +10 to +30VDC. The power supply
ripple must be limited to 100 mV peak-to-peak, and the immediate ripple
voltage should be maintained between +10 and +30 VDC.
Diagnostic Indicators
Diagnostic indicators are located on the front panel of the ADAM
system. They show both normal operation and system status in your
remote I/O system. The indicators are:
• System status (PWR, RUN)
• Communication status (TX, RX)
• I/O module status
2-2 ADAM-5000
Chapter 2
A complete description of the diagnostic indicators and how to use
them for troubleshooting is explained in Chapter 7.
Figure 2-1 ADAM-5000 Diagnostic indicators
Setting the Network Address Switch
Set the network address using the 8-pin DIP switch. Valid settings
range from 0 to 255 (00h to FFh) where ON in any of the 8 DIP switch
positions equates to a binary 1, and OFF equates to a binary 0.
For example, if the Node ID is 03h the DIP switch settings for switches
1 and 2 (representing bits 1 and 2) would both be ON while the rest of
the switches would be OFF . The default Node ID is 01h

the module straight into the system until it is firmly seated in the
backplane connector. Once the module is inserted into the system,
push in the retaining clips (located at the top and bottom of the
module) to firmly secure the module to the system.

2.3 I/O Slots and I/O Channel Numbering
The ADAM-5000/485 system each provides 4 slots for use with I/O
modules. The I/O slots are numbered 0 thru 3, and the channel
numbering of any I/O module in any slot starts from 0. The ADAM5000E system each provides 8 slots for use with I/O modules. The
slots are numbered 0 thru 7. For example, ADAM-5017 is a 8-channel
analog input module, its channel numbering is 0 through 7.

2.4 Mounting
The ADAM-5000 system can be installed on a panel or DIN rail.
Panel Mounting
Mount the system on the panel horizontally to provide proper ventilation. You cannot mount the system vertically, upside down or on a flat
horizontal surface. A standard #7 tating screw (4mm diameter) should
be used.

Installation Guideline
DIN Rail Mounting
The system can also be secured to the cabinet by using mounting
rails. If you mount the system on a rail, you should also consider
using end brackets on each end of the rail. The end brackets help
keep the system from sliding horizontally along the rail. This helps
minimize the possibility of accidentally pulling the wiring loose. If you
examine the bottom of the system, you will notice two small retaining
clips. To secure the system to a DIN rail, place the system onto the rail
and gently push up on the retaining clips. The clips lock the system
on the rail. T o remove the system, pull down on the retaining clips, lift
up on the base slightly, and pull it away from the rail.

2.5 Wiring and Connections
Chapter 2
This section provides basic information on wiring the power supply
and I/O units, and on connecting the network.
DC Power Supply Unit Wiring
Be sure that the DC power supply voltage remains within the allowed
fluctuation range of between 10 to 30 VDC. T erminals +VS and GND are
for power supply wiring.
Note: The wire(s) used should be at least 2mm2.
ADAM-5000 2-9
Installation Guideline
INIT* is used for changing baud rate and checksum. COM is provided
as reference to the RS-485 ground signal. DATA+ and DATA- are
provided for the RS-485 twisted pair connection.
Figure 2-7 ADAM-5000 Wiring and connections
I/O Modules Wiring
The system uses plug-in screw terminal blocks for the interface
between I/O module and field devices. The following information must
be considered when connecting electrical devices to I/O modules.
1 . The terminal block accepts 0.5 mm2 to 2.5 mm2 wires
2. Always use a continuous length of wire, do not combine
wires to attain needed length
3. Use the shortest possible wire length
4 . Use the wire trays for routing where possible

5 . Avoid running wires near high energy wiring
6 . A void running input wiring in close proximity to output
wiring where possible
7. Avoid creating sharp bends in the wires
RS-485 Port Connection
There is a pair of DB9 ports in the ADAM-5000 system. The ports are
designed to link the RS-485 through a cable to a network in a system.
The pin assignment of the port is as follows:
Pin No. Description
Pin 1 RS-485 Data -
Pin 2 RS-485 Data +
Pin 3 Not Used
Pin 4 Not Used
Pin 5 RS-485 Signal Ground
Pin 6 Not Used
Pin 7 Not Used
Pin 8 Not Used
