1 Introduction
1.1Overview
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
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 of the module’s configuration parameters including I/O address, communication speed, 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 V
DC
power
supply, they accept any power unit that supplies power within the range of +10 to +30
V
. The power supply ripple must be limited to 5 V peak-to-peak, and the immediate
DC
ripple voltage should be maintained between +10 and +30 V
DC
.
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 communications to and from the module are performed in ASCII, which means
that ADAM modules can be virtually programmed in 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 which extends the
maximum communication distance up to 4,000 ft. The host computer is connected to
the RS-485 network with one of its COM ports through the ADAM-452x module (RS232 to RS-422/485 converter).
To boost the network’s throughput, ADAM RS-485 repeater uses a logical RTS signal
to manage the repeater’s direction. The only two wires that are needed for the RS485 network, DATA+ and DATA-, are inexpensive shielded twisted pair.
ADAM-4000 Series User Manual2
Panel/DIN Rail mounting
Chapter 1Introduction
ADAM modules can be mounted on any panels, brackets, or DIN rails. They can also
be stacked together.
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
Since all the configurations are controlled by software, the protection provided by the
packaging is very important. The plastic outer shell enhances resistance against corrosive materials, moisture and vibrations. ADAM modules’ low power requirements
help them to operate in temperatures from 0 to 70 ?, and in humidity from 0 to 95%
(non-condensing). They are compactly built using automated SMT technology.
Therefore, they can be implemented in water-tight and explosion-proof industrial
enclosures.

2 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 configure modules before
they are installed in a network. To help you connect ADAM modules with sensor
inputs, several wiring examples are provided. At last, you will find a programming
example using the ADAM command set at the end of this chapter.
Be sure to plan the layout and configuration of your network carefully before you
start. Guidelines regarding layout are given in Appendix E: RS-485 Network.
2.1System 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 char-
acters with a 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)
RS-232/RS-485 ADAM Repeater (optional)
Host computer
Any computer or terminal that can output in ASCII format over either RS-232 or RS485 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 transformerbased 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 V
Operation is guaranteed when using any power supply between +10 and +30 V
Power ripples must be limited to 5 V peak to peak while the voltage in all cases must
be maintained between +10 and +30 V
enced at module connector. When modules are powered remotely, the effects of DC
voltage drops must be considered.
All modules use on-board switching regulators to sustain good efficiency over the 10
to 30 V input range; therefore, we can assume that the actual drawn current is
inversely proportional to the DC voltage.
The following example shows how to calculate the required current that a power supply should provide.
Assume that a +24 V
distance between modules and power supply is not significant enough to cause a DC
voltage drop. One ADAM-4011 module consumes a maximum of 1.2 Watts (W). The
total required power will equal to 5 x 1.2=6 W. 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 in long communication lines (>500 feet), it is often more
reliable to obtain power locally through modular power supplies. These inexpensive
units can be easily obtained from any electronic retail stores.

ADAM-4000 Series User Manual6
The power cables should be selected according to the length of the power lines and
the number of modules connected. When implementing a network with long cables,
the use of thicker wire is more suitable due to the limitation of DC voltage drop. Furthermore, long wires can also cause interference with communication wires.
Figure 2.1 Power Supply Connections
We advise the following standard colors (as indicated on the modules) for each
power line:
+Vs (R) Red
GND (B) Black
Chapter 2Installation Guideline
Communication Wiring
We recommend the use of shielded-twisted-pair cable in the ADAM network for
reducing interference purpose, but the cable has to comply with the EIA RS-485
standard. Furthermore, only one set of twistedpair cable is required for transmitting
Data. We advise the following standard colors (as indicated on the modules) for each
the communication line:
DATA+ (Y) Yellow
DATA- (G) Green
ADAM Utility Software
A menu-driven utility program is provided for ADAM module configuration, monitoring
and, calibration. It also includes a terminal emulation program that lets you communicate through the ADAM command set. (See Appendix D, Utility Software and online
help)
Note!User can refer our help file to see more details for explanation of Utility
operation.

ADAM Communication Speed
In ADAM series, the baud rate can be configured from 1200 bps to 38.4 Kbps. However, the baud rate of all modules in an RS-485 network must be the same.
ADAM Isolated RS-232/RS485 Converter (optional): ADAM-452x
When the host computer or terminal only has a RS-232 port, an ADAM Isolated RS-
232/RS-485 Converter is required. Since this module is not addressable by the host,
the baud rate must be reset using a switch inside the module. The factory default setting is 9600 baud.
ADAM Repeater (optional): ADAM-451x
When communication lines exceed 4000 ft (1200 meter) or more than 32 ADAM
modules are connected, a repeater should be implemented. In a network, up to eight
Repeater modules can be connected allowing connection up to 255 ADAM modules.
As with the Converter module, the Repeater module is not addressable by the host
and the baud rate must be reset by changing the switch inside the module. The factory default setting is 9600 baud.
ADAM-4000 Series User Manual8
2.2Basic 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
if the baud rate is set correctly beforehand.
Default Factory Settings
Baud rate: 9600 Bit/sec.
Address: 01 (hexadecimal)
The basic hook-up for module configuration is shown below.
Chapter 2Installation Guideline
Figure 2.2 Basic Hook-up of ADAM Module to Host Switches
9ADAM-4000 Series User Manual
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.
Configuration with the ADAM Utility Software
The easiest way to configure the ADAM module is by using the ADAM utility software. It is a user friendly structured menu program that will guide you through every
step of the configuration. (See Appendix D, Utility Software)
Changing the protocol from ADAM ASCII to Modbus
Some ADAM-4000 modules support both ADAM ASCII and Modbus protocols, and
the factory default setting of these modules is ADAM ASCII protocol. If you would like
to configure the modules to Modbus protocol, please refer to Appendix H which
describes how to change the protocol in ADAM utility.
Configuration with the ADAM command set
ADAM modules can also be configured by issuing direct commands through a terminal emulation program that is part of the ADAM utility software. The following example will guide you through the setup of an analog input module. Assume an ADAM4011 Analog Input module still has its default settings (baud rate 9600 and address
01h), and you are being requested to send its default settings before any reconfiguration is made.
Note!An analog input module requires a maximum of 7 seconds to perform
auto calibration and ranging after reboot or start up.
During this time span, the module can not be addressed to perform any
other actions.
Example:
Make sure that the module is properly connected and turn on all the connected
devices. Then, start the terminal emulation program, and type in the following command:
$012(cr)
The command above requests the module with address 01 to send its configuration
status
!01050600
Module at address 01 responds that it is configured for an input range of +/-2.5 V,
baud rate of 9600, integration time of 50 ms (60 Hz).
The code also shows engineering units and no checksum checking or generation.
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
ADAM-4000 Series User Manual10
set data format to engineering units
(Please refer to Chapter 4, a full description of Command set syntax for an analog
input module)
When the module received the configuration command, it will respond with its new
address as shown below:
!07(cr)
Before giving more commands to the module, please wait for 7 seconds to let the
new configuration settings to take effect.
Note!All reconfiguration except for changing baud rate and checksum values
can be done dynamically, and the modules are not required to reset.
However, all the connected devices are required to reset by turning
power off and on after the baud rate or checksum values are changed.
The baud rate or checksum values should be the same for all the connected devices after the reconfiguration. See the next page for a strategy in changing baud rate and checksum of the network.
2.3Baud Rate and Checksum
Chapter 2Installation Guideline
ADAM modules contain EEPROMs to store configuration information and calibration
constants. The EEPROM replaces the conventional array of switches and pots that
are originally used for specifying baud rate, input and output range… etc.
Since there is no visual indication of a module’s configuration status, it is impossible
to know the baud rate, address and other settings just by looking at it. It might not be
possible to establish communications with a module whose baud rate and address
are unknown. To overcome this problem, most modules have an input terminal
labeled INIT*. Booting the module while connecting the INIT* terminal with the module’s GND terminal forces the configuration into a known state called the INIT* state.
Besides, some newer modules have INIT switch which you can set “Init” or “Normal”
(See Figure 2.4). If you set the switch to “Init”, then it becomes INIT* state.
INIT* state defaults:
Baud rate: 9600
Address: 00h
Checksum: disabled
Forcing the module in 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.
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 settings can only be changed by putting a module in the INIT* state.
Changed settings can only take effect after a module is rebooted
11ADAM-4000 Series User Manual
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) or set the INIT switch to “Init” (See Figure 2-4)
Figure 2.3 Grounding the INIT* Terminal
Figure 2.4 Set INIT switch to “Init”
Configure the checksum status and/or the baud rate.
Switch the power OFF to the ADAM Module.
Remove the grounding of the INIT* terminal and turn on the module, or set the
INIT switch to “Normal”.
Check the settings (If the baud rate has changed, the settings on the host com-
puter should be changed accordingly).

3.2ADAM-4011/4011D Thermocouple Input Modules
The ADAM-4011/4011D Thermocouple Input Modules use a microprocessor-controlled integrating A/D converter to convert sensor voltage, current or thermocouple
signal into digital data. The digital data is then translated into either two’s complement hexadecimal format or percentage of full-scale range (FSR) according to the
module’s configuration. When prompted by the host computer, the data is sent
through a standard RS-485 interface.
The ADAM-4011/4011D Thermocouple Input Modules offer signal conditioning, A/D
conversion, ranging, and RS-485 digital communication functions. They protect your
equipment from power surges at the ground terminal by providing opto-isolation of
the A/D input and transformer based isolation up to 3000 V

Open Thermocouple Detection and Input Surge Protection (ADAM-4011D only)
The ADAM-4011D provides an open thermocouple detection function. Users can use
a simple command to detect whether the thermocouple is opened or closed. The
module also provides surge protection on its input channel. Internal high-speed transient suppressor on its input channel protects the module from dangerous spikes and
voltages.
Front Panel LED Indicator (ADAM-4011D only)
The 4½ digits LED display on the back of the ADAM-4011D lets you monitor the process readings right at their source. The module displays readings in a wide variety of
formats as well as high-low alarm messages. The ADAM-4011D offers flexibility, easy
installation, and direct availability of process data. For critical process monitoring, this
module is the ideal choice.
Digital Input/Output
The ADAM-4011/4011D Thermocouple Input Modules also contain two digital outputs
and one digital input. Outputs are open-collector transistor switches that may be controlled by the host computer. They can control solid-state relays, which may be used
to control heaters, pumps, and other electrical powered equipment. The digital inputs
may be read by the host computer and used to sense the state of a remote digital signal.
Chapter 3I/O Modules
Event counting
The event counter is connected to the Digital Input channel and can be used to keep
track of the total amount of external low-speed pulses. Its accumulated maximal
count is 65535. The count will maintain at 65535 even if the actual number of events
exceeds 65535. The counter can be read or reset to zero by the host computer.
Since the Event counter’s data are not stored in EEPROM, the event counter is
cleared and set to zero after every reset or start up of the analog input module.
Alarm signaling
Analog input modules include High and Low alarm functions. High and Low alarm
limits may be downloaded into the module’s EEPROM by the host computer.
The alarm functions can be enabled or disabled remotely. When the alarm function is
enabled, both Digital Output channels are used to indicate the High and Low alarm
state. Digital Output channel 1 (DO1) equals to High alarm state, and Digital Output
channel 0 (DO0) equals to Low alarm state. The High and Low alarm states can be
read at any time by the host computer.
Every A/D conversion will be followed by a comparison with the High and Low limit.
When the input value exceeds one of these limits, the High or Low alarm state is set
to ON.
There are two alarm mode options, Momentary and Latching. If the alarm is in Latching mode, the alarm will stay on even if the input value returns within the limits. An
alarm in Latching mode can be turned OFF by giving a Clear Alarm command from
the host computer. A Latching alarm is cleared by the module when the opposite
alarm is set. When
the module receives a value that is lower than the Low alarm limit, it will clear the
High alarm and turn the Low alarm ON.
When the alarm is in Momentary mode, the alarm will be turned OFF as soon as the
input value returns within the limits.
23ADAM-4000 Series User Manual
The arrangement of coupling High and Low alarm states with Digital Output lines may
be utilized to build ON/OFF controllers that
can operate without the involvement of host computer.
Function Description for the ADAM-4011 Thermocouple Input Module
To provide a better understanding of the ADAM module functions, the following is a
description of the module ADAM-4011 with the most extensive set of functions.
All analog input data first flow through the PGA (programmable gain amplifier). The
amplifier can vary its gain from 1 to 128. The PGA then automatically adjusts the signal to a range from -2.5 V to +2.5 V.
This ensures an optimal input voltage and resolution for the A/D converter.
The A/D conversion is supervised by the microprocessor that holds the calibration
software. Two kinds of calibrations, Auto Zero and Auto Span calibrations, take place
automatically in startup or reset. Normal calibration is used to adjust the signal
according to calibration parameters defined by the user.
The digital 10 Hz filter provides a steady state output by using the unction.
Before the data enter the microprocessor, they pass through an optical isolation
device which prevents the chance of circuit damaging caused by power surges from
the ground terminal.
The microprocessor has six basic functions:
- Linearization of T/C (Thermocouple)
- Communication software and command set
- Calibration software
- Alarm monitoring
- Event counting
- Management of the EEPROM device that holds the system parameters
- Data transformation
After data have been transformed to the right data format, they are being passed on
to the RS-485 output port.
If an input value exceeds the High alarm setting or falls below the Low alarm setting,
a flag is set in one of the Digital Output channels.
Finally, the on-board switching regulator accepts voltage between +10 and +30 V

A strain gauge input module uses a microprocessor-controlled integrating A/D converter to convert sensor voltage or current signals into digital data for load cell and
stress measurement. The digital data are then translated into either, two’s complement hexadecimal format or percentage of full-scale range (FSR) according to the
module’s configuration. When prompted by the host computer, the data are sent
through a standard RS-485 interface.
The strain gauge input module offers signal conditioning, A/D conversion, ranging,
and RS-485 digital communication functions.
They protect your equipment from power surges at the ground terminal by providing
opto-isolation of the A/D input and up to 3000 VDC transformer based isolation.
Excitation Voltage Output
A strain gauge input module can supply single channel voltage output for excitation.
The module receives digital input from the host computer, and the format of the data
is engineering units. It then uses its microprocessor-controlled D/A converter to convert the digital data into output signals.
Strain gauge input modules protect your equipment from power surges at the ground
terminal by providing opto-isolation of the D/A output and up to 3000 VDC transformer-based isolation.
Digital Outputs

Alarm signaling
Strain Gauge input modules include High and Low alarm functions. High and Low
alarm limits may be downloaded into the module’s EEPROM by the host computer.
The alarm functions can be enabled or disabled remotely. When the alarm function is
enabled, both Digital Output channels are used to indicate the High and Low alarm
states. Digital Output channel 1 (DO1) equals to High alarm state and Digital Output
channel 0 (DO0) equals to Low alarm state. The High and Low alarm state can be
read at any time by the host computer.
Every A/D conversion will be followed by a comparison with the High and Low limits.
When the input value exceeds one of these limits, the High or Low alarm state is set
to ON.
There are two alarm mode options, Momentary and Latching. If the alarm is in Latching mode, the alarm will stay on even when the input value returns within limits. An
alarm in Latching mode can be turned OFF by issuing a Clear Alarm command from

You will get a true read-back of the analog output signal from the unit’s ADC, which
monitors the output independently. You can also specify slew rates and start up currents through the configuration software. The Analog Output Module can supply single-channel analog output in a range of voltages or currents.
Furthermore, it will protect your equipment from power surges at the ground terminal
by providing opto-isolation of the D/A output and up to 3000 VDC transformer based

ADAM-4024 is a 4-channel analog output module with mixed type I/O. Under some
circumstances, it is, however, a demand for multiple analog outputs to fulfill particular
applications without many duplicate modules. ADAM-4024 is designed to achieve
this purpose by integrating four A/O channels and four isolated D/I channels into only
one module. The four digital input channels function as an interlock for emergency
latch output.
ADAM-4024 inherited from ADAM-4021, but provide multi-range AO support, allows
its four A/O channels working at the same time with different and more output ranges.
For example, it can have 4~20 mA and ±10 V at its output. To ensure the operation of
machines and facilities, ADAM-4024 has the functionality of slew rate control. Output
slope is programmable through ramping/clamping the slew rate. Unlike traditional

3.21 ADAM-4080/4080D Counter/Frequency Input
Modules
ADAM-4080/4080D Counter/frequency input module has two 32- bit counter input
channels (counter 0 and counter 1) with built-in programmable timer for frequency
measurement. These cost-effective modules let you monitor counter/frequency data
as measurements are taken.
Front Panel LED Indicator (ADAM-4080D only)
The 5-digit LED display of the ADAM-4080D lets you monitor its counter data right at
the source. The module's LED display shows counter values as well as high-low
alarm messages when the counter exceeds its programmed limits (direct display).
Another option is to display the data sent by the host computer. The module first
sends counter data to the host computer for conversion or calculation. The host computer then sends the data back to the ADAM- 4080D and displays on the module's
LED display (remote display).
Signal Input Mode
The ADAM-4080/4080D provides separate terminals for photo isolated input and
non-isolated input to simplify the wiring. Optoisolated input provides 2500 V
lation to protect your equipment from power surges at the ground terminal. After you
make the physical connections, program the module to identify which of its two input
terminals should be activated (isolated or non-isolated terminals).

Programmable Digital Filter
The ADAM-4080/4080D module includes a unique programmable digital filter to
reject noise from the input lines. You can specify separate time constant like minimum signal width at high level and minimum signal width at low level. This provides
stable output readings.
Programmable Threshold
When the ADAM-4080/4080D is programmed for non-isolated input, you can set a
high and low trigger level. Like the programmable digital filter, the programmable
threshold rejects noise from the input lines and provides a stable input readings
External Control (Gate mode)
Aside from the GND and counter terminal, each channel has a gate terminal to connect to an external gate signal. The gate signal (high or low) can trigger the counter
from start or stop counting. The gate mode can be among these three options, low,
high or disabled (low means that counting starts when the gate signal is low. It stops
once the gate signal becomes high)
Programmable Alarm Output
The ADAM-4080 module provides a configurable alarm for each counter. The ADAM4080D provides high and low alarm functions for counter 0. When the counter
reaches an alarm limit, it will trigger the built-in digital output of machine ON/OFF
control. The alarm limits may be downloaded into the module's EEPROM by the host
computer. The initial count value of ADAM-4080 module's counter can be configured
in any values.
ADAM-4000 Series User Manual80
The alarm functions can be enabled or disabled remotely. When the alarm functions
are enabled, digital output channels are used to indicate the alarm states. For ADAM4080, digital output channel 0 equals to the alarm state of counter 0, and digital output channel 1 equals to the alarm state of counter 1. For ADAM-4080D, digital output
channel 0 equals to the low alarm state of counter 0, and digital output channel 1
equals to the high alarm state of counter 0.
Every A/D conversion will be followed by a comparison of alarm limits. If the input
value exceeds one of these limits, the corresponding alarm state is set to ON.
There are two alarm mode options, momentary and latching, for ADAM-4080D. If the
alarm is in latching mode, the alarm will stay on even when the input value returns
within the limits. An alarm in latching mode can be turned off by issuing a Clear Alarm
command from the host computer. A latching alarm is cleared by the module when
the opposite alarm is set. For example, the alarm is in latching mode and the high
alarm is then turned ON. When the module receives a value that is lower than the low
alarm limit, it will clear the high alarm and turn the low alarm ON.
When the alarm is in Momentary mode, the alarm will be turned OFF as soon as the
input value returns within the limits. The arrangement of coupling high and low alarm
states with digital output lines may be utilized to build ON/OFF controllers that can
In order to avoid communication conflicts among devices trying to send data simultaneously, all the traffics are coordinated by the host computer. This action is initiated
by the host computer using a command/response protocol.
When the modules are not transmitting, they are in listening mode. The host issues a
command to a module with a specified address and waits for the module’s response.
If there is no response, a timeout aborts the sequence and returns the control to the
host.
Changing ADAM’s configuration might require the module to perform auto calibration
before changes may take effect. This is the case when the range is modified especially. The module has to perform all stages of auto calibration which is also performed during the start up. When the calibration process is underway, the module
does not respond to any other commands. The command set in the following pages
includes the exact delays that might occur as modules are reconfigured.
4.2Syntax
[delimiter character][address][command][data][checksum] [carriage return]
Every command begins with a delimiter character. There are four valid characters: a
dollar sign $, a pound sign #, a percentage sign % and an at sign @.
The delimiter character is followed by a two-character address (hexadecimal) that
specifies the target module. The actual two-character command follows by the
address. Depending on the command, an optional data segment may follows by a
command string. Furthermore, an optional two-character checksum may be
appended to the total string. Every command is terminated by a carriage return (cr).
ALL COMMANDS SHOULD BE ISSUED IN UPPERCASE CHARACTERS!
Before the command set is given, we provide an I/O module commands search table
to help you find the commands that you wish to use. The command set is divided into
the following three categories:
Each Category starts with a command summary of a particular type of module. However, they are explained in more depth at Chapter 5, 6 & 7 with detailed datasheets of
each individual commands.
Although commands in different subsections sometimes share the same format, the
effect they have on a certain module can be completely different from others. For
example, the configuration command %AANNTTCCFF affects analog input modules
and analog output modules differently. The full command set for every module is
listed below.
