Introduction

1-2 ADAM 4000 Series User's Manual
Introduction
1.1 Overview
The ADAM Series is a set of intelligent sensor-to-computer interface
modules containing built-in microprocessor. They are remotely controlled
through a simple set of commands issued in ASCII format and transmitted
in RS-485 protocol. They provide signal conditioning, isolation, ranging,
A/D and D/A conversion, data comparison, and digital communication
functions. Some modules provide digital I/O lines for controlling relays
and TTL devices.
Software Configuration and Calibration
ADAM modules contain no pots or switches to set. By merely issuing a
command from the host computer, you can change an analog input module
to accept several ranges of voltage input, thermocouple input or RTD
input. All the module’s configuration parameters including I/O address,
speed, parity, HI and LO alarm, calibration parameters settings may be set
remotely. Remote configuration can be done by using either the provided
menu-based software or the command set’s configuration and calibration
commands.
By storing configuration and calibration parameters in a nonvolatile
EEPROM, modules are able to retain these parameters in case of power
failure.
Watchdog Timer
A watchdog timer supervisory function will automatically reset the ADAM
modules in the event of system failure. Maintenance is thus simplified.
Power Requirements
Although the modules are designed for standard industrial unregulated 24
VDC power supply , they accept any power unit that supplies power within
the range of +10 to +30 VDC. The power supply ripple must be limited to 5
V peak-to-peak, and the immediate ripple voltage should be maintained
between +10 and +30 VDC.

Chapter 1 Introduction 1-3
Chapter 1
Connectivity and Programming
ADAM modules can connect to and communicate with all computers and
terminals. They use RS-485 transmission standards, and communicate with
ASCII format commands. The command set for every module type consists
of approximately ten different commands. The command set for input
modules is larger because it incorporates alarm functions. All communica-
tions to and from the module are performed in ASCII, which means that
ADAM modules can be programmed in virtually any high-level language.
RS-485 Network
The RS-485 network provides lower-noise sensor readings, as modules can
be placed much closer to the source. Up to 256 ADAM modules may be
connected to an RS-485 multi-drop network by using the ADAM RS-485
repeater, extending the maximum communication distance to 4,000 ft. The
host computer is connected to the RS-485 network with one of its COM
ports through the ADAM RS-232/RS-485 converter.
To boost the network’s throughput, the ADAM RS-485 repeaters use a
logical RTS signal to manage the repeater’s direction. Only two wires are
needed for the RS-485 network: DATA+ and DATA-. Inexpensive
shielded twisted pair wiring is employed.
Panel/DIN Rail mounting
ADAM modules mount on any panel, on provided brackets, on DIN rails
or may be stacked together.

1-4 ADAM 4000 Series User's Manual
Introduction
The RS-485 network, together with screw-terminal plug connectors, allows
for system expansion, reconfiguration and repair without disturbing field
wiring.
Protection against the environment
Hardened plastic packing forms the outer shell of every module. Since all
configuration is controlled by software, the module is not designed to be
opened. This greatly enhances resistance against corrosive materials,
moisture and vibration. ADAM modules’ low power requirements help
them to operate in temperatures from 0 to 70oC,and in humidities from 0 to
95% (non-condensing). They’re built compactly using automated SMT
technology so you can pack them into water-tight and explosion-proof
industrial enclosures.

Installation Guideline

2-2 ADAM 4000 Series User's Manual
Installation Guideline
This chapter provides guidelines to what is needed to set up and install an
ADAM network. A quick hookup scheme is provided that lets you config-
ure modules before they are installed in a network.
To help you to connect ADAM modules with sensor inputs, several wiring
examples are provided. Finally, you will find at the end of this chapter a
programming example using the ADAM command set.
Be sure to carefully plan the layout and configuration of your network
before you start. Guidelines regarding layout are given in Appendix E: RS-
485 Network.
NOTICE: Except for the communication modules, which have on-board
switches for their baud rate setting, ADAM modules should not be opened.
There is no need to open the ADAM modules: all configuration is done
remotely and there are no user serviceable parts are inside. Opening the
cover will therefore void the warranty.

Chapter 2 Installation Guideline 2-3
Chapter 2
2.1 System Requirements to set up an ADAM network
The following list gives an overview of what is needed to setup, install and
configure an ADAM environment.
•ADAM modules
•A host computer, such as an IBM PC/AT compatible, that can output
ASCII characters with an RS-232C or RS-485 port.
•Power supply for the ADAM modules (+10 to +30 VDC )
•ADAM Series Utility software
•ADAM Isolated RS-232/RS-485 Converter (optional)
•ADAM Repeater (optional)
Host computer
Any computer or terminal that can output in ASCII format over either RS-
232 or RS-485 can be connected as the host computer. When only RS-232
is available, an ADAM RS-232/RS-485 Converter is required to transform
the host signals to the correct RS-485 protocol. The converter also provides
opto-isolation and transformer-based isolation to protect your equipment.
Power supply
For the ease of use in industrial environments the ADAM modules are
designed to accept industry standard +24 VDC unregulated power. Opera-
tion is guaranteed when using any power supply between +10 and +30 VDC
. Power ripples must be limited to 5 V peak to peak while the voltage in all
cases must be maintained between +10 and +30 VDC . All power supply
specifications are referenced at module connector. When modules are
powered remotely, the effects of line voltage drops must be considered.
All modules use on-board switching regulators to sustain good efficiency
over the 10-30 V input range, therefore we can assume that the actual
current draw is inversely proportional to the line voltage. The following
example shows how to calculate the required current that a power supply
should be able to provide.

2-4 ADAM 4000 Series User's Manual
Installation Guideline
Assume that a +24 VDC will be used to power five ADAM-4011 Analog
Input Modules. The distance from power supply to modules is not so big
that significant line voltage drop will occur. One ADAM-4011 module
consumes a maximum of 1.2 Watts. The total required power will equal 5 x
1.2 = 6 Watts. A power supply of +24 VDC should therefore be able to
supply a minimal current of 6 / 24 = 0.25 Amps.
Small systems may be powered by using wall-mounted modular power
supplies. Also when modules operate on long communication lines (>500
feet) it is often more reliable to power the modules locally with modular
power supplies. These inexpensive units can easily be obtained from any
electronics retail store.
The power cables should be selected according to the number of modules
connected and the length of the power lines. When using a network with
long cables, we advise the use of thicker wire to limit the line voltage drop.
In addition to serious voltage drops, long voltage lines can also cause
interference with communication wires.
Figure 2-1 Power Supply Connections
We advise that the following standard colors (as indicated on the modules)
be used for power lines:
+Vs (R) Red
GND (B) Black

Chapter 2 Installation Guideline 2-5
Chapter 2
Communication Wiring
We recommend that shielded-twisted-pair cables that comply with the EIA
RS-485 standard be used with the ADAM network to reduce interference.
Only one set of twisted-pair cables is required to transmit both Data and
RTS signals. We advice that the following standard colors (as indicated on
the modules) be used for the communication lines:
DATA+ (Y) Yellow
DATA- (G) Green
ADAM Utility Software
A menu-driven utility program is provided for ADAM module configura-
tion, monitoring and calibration. It also includes a terminal emulation
program that lets you easily communicate through the ADAM command
set. (See Appendix D, Utility Software)
ADAM Communication Speed
In ADAM series, the baudrate can be configured from 1200 bps to 38.4
Kbps. And the baudrate of all modules in an RS-485 network must be the
same.
ADAM Isolated RS-232/RS485 Converter (optional)
When the host computer or terminal has only a RS-232 port, an ADAM
Isolated RS-232/RS-485 Converter, connected to the host’s RS-232 port, is
required. Since this module is not addressable by the host, the baud rate
must be set using a switch inside the module. The factory default setting is
9600 baud.
ADAM Repeater (optional)
When communication lines exceed 4000 ft (1200 meter) or the number of
ADAM modules connected is more than 32, a repeater should be connect-
ed to expand the first segment. Up to 8 Repeater modules can be connected
allowing connection of up to 256 ADAM modules. As with the Converter
module, the Repeater module is not addressable by the host and the baud
rate must be set by changing the switch inside the module. The factory
default setting is 9600 baud.

Figure 2-2 Basic Hook-up of ADAM Module to Host Switches
The following items are required to configure a module: an ADAM
converter module, a personal computer with RS-232 port (baud rate set to
9600) and the ADAM utility software.
2.2 Basic configuration and hook-up
Before placing a module in an existing network, the module should be
configured. Though all modules are initially configured at the factory, it is
recommended to check that the baud rate is set correctly.

Configuration with the ADAM Utility Software
The easiest way to configure the ADAM module is by using the ADAM
utility software: an easy-to-use menu-structured program will guide you
through every step of the configuration. (See Appendix D, Utility Soft-
ware)
Configuration with the ADAM command set
ADAM modules can also be configured by issuing direct commands from
within a terminal emulation program that is part of the ADAM utility
software.
The following example guides you through the setup of an analog input
module. Assume that an ADAM-4011 Analog Input module still has its
default settings (baud rate 9600 and address 01h). Before the module is
reconfigured, it is first requested to send its default settings.
NOTICE:An analog input module requires a maximum of 7 seconds to
perform auto calibration and ranging after it is rebooted or powered on.
During this time span, the module can not be addressed to perform any
other actions.
Example:
Make sure that the module is properly connected as shown in figure 2-5.
Power up all the connected devices, start the terminal emulation program,
and issue the following command:
$012(cr)
requests that module with address 01 send its configuration status
!01050600
Module at address 01 responds that it is configured for an input range of +/
-2.5 V, baud rate 9600, integration time of 50 ms (60 Hz), engineering
units and no checksum checking or generation.

2-8 ADAM 4000 Series User's Manual
Installation Guideline
To change the configuration setting of the analog input module, the
following command is issued:
%01070F0600(cr)
% = change configuration
01 = target module at address 00 to:
07 = change address to 07 hexadecimal
0F = set input range to Type K thermocouple
06 = set baud rate to 9600
00 = set integration time to 50 ms (60 Hz)
disable checksum
set data format to engineering units
(See Chapter 4, Command Set for a full description of the syntax of the
configuration command for an analog input module)
When the module received the configuration command it will respond with
its new address:
!07(cr)
Wait 7 seconds to let the new configuration settings take effect before
issuing a new command to the module.
NOTICE: All reconfiguration except changing of baud rate and checksum
values can be done dynamically, i.e. the modules need not to be reset.
When changing the baud rate or checksum, these changes should be made
for all connected devices. After reconfiguration, all modules should be
powered down and powered up to force a reboot and let the changes take
effect. See the next page for a strategy for changing baud rate and or
checksum for an entire network.

Chapter 2 Installation Guideline 2-9
Chapter 2
2.3 Baud rate and Checksum
Adam modules contain EEPROMs to store configuration information and
calibration constants. The EEPROM replaces the usual array of switches
and pots required to specify baud rate, input/output range etc. All of the
ADAM modules can be configured remotely through their communication
ports, without having to physically alter pot or switch settings.
Since there is no visual indication of a module’s configuration status, it is
impossible just by looking at it what the baud rate, address and other
settings are. It might not be possible to establish communications with a
module whose baud rate and address are unknown. To overcome this
problem, every module has an input terminal labeled INIT*. By booting
the module while connecting the INIT* terminal with the module’s GND
terminal, the modules configuration is forced into a known state. This state
is called the INIT* state.
INIT* state defaults:
Baud rate: 9600
Address: 00h
Checksum: disabled
Forcing the module in the INIT* state does not change any parameters in
the module’s EEPROM. When the module is in the INIT* state with its
INIT* and GND terminals shorted, all configuration settings can be
changed and the module will respond to all other commands normally.

2-10 ADAM 4000 Series User's Manual
Installation Guideline
Changing Baud rate and Checksum
Baud rate and checksum settings have several things in common:
•They should be the same for all modules and host computer.
•Their setting can only be changed by putting a module in the INIT*
state.
•Changed settings can only take effect after a module is rebooted
To alter baud rate or checksum settings you must perform the following
steps:
•Power on all components except the ADAM Module.
•Power the ADAM module on while shorting the INIT* and GND
terminals (See Figure 2-3).
•Wait at least 7 seconds to let self calibration and ranging take effect.
•Configure the checksum status and/or the baud rate.
•Switch the power to the ADAM Module OFF.
•Remove the grounding of the INIT* terminal and power the module on.
•Wait at least 7 seconds to let self calibration and ranging take effect.
•Check the settings (If the baud rate has changed, the settings on the host
computer should be changed accordingly).
Figure 2-3 Grounding the INIT* Terminal
