1.0 Introduction
The D6000 series RS-485 serial interface modules are a complete family of data acquisition modules. The family of modules includes multi-channel analog input measurement modules, multiple channel analog output modules, and digital modules.
The D6000 series modules communicate using the Modbus RTU protocol. This protocol very popular in the data acquisition market and is supported by almost every commercial data acquisition program in the market today. Thus providing access to wide variety of software control programs that can meet almost any application budget.
The D6000 series analog input modules contain seven differential analog input channels and can measure voltages, current, and thermocouples. There are four versions available, the D6100, D6200, D6300 and the D6400. The D6100 module can measure DC voltage signals. The D6200 module can measure seven 4-20mA current loops. The D6300 series can measure eight user­selectable thermocouple types. The D6400 series can measure six selectable voltage input ranges, one current input range, and eight selectable thermocouple types.
The D6500 series analog output modules contain two output channels for generating either a voltage or current output signal. Each analog output channel is user-selectable as either a voltage or a current output. These analog output signals can be used as control inputs for items such as motor controls, valve controls, and other control devices. Each analog output channel also contains a programmable communications watchdog timer for instances when communications to the module is lost.
The D6700 series digital input and output modules each contain 15-bits of input or output. The digital input modules contain internal pull-ups on each bit for direct connection of dry contact switches. The digital outputs are open-collector outputs that can be connected up to 30Vdc and can sink 100mA per bit. The open-collector allows the modules to be used in a wider variety of control applications. The digital output module also contains a programmable watchdog timer for instances where communications to the module is lost.
Mixing and matching the D6000 series modules together in an application provides a user with all the measurement and control hardware for a complete process control system.

1.0 Configuration & Getting Started
Default Mode
All D6000 series modules contain an EEPROM (Electrically Erasable Programmable Read Only Memory) to store setup information and calibration constants. The EEPROM replaces the usual array of switches and pots necessary to specify baud rate, address, parity, etc. The memory is nonvolatile which means that the information is retained even if power is removed. No batteries are used so it is never necessary to open the module case.
The EEPROM provides tremendous system flexibility since all of the module’s setup parameters may be configured remotely through the communications port without having to physically change switch and pot settings. There is one minor drawback in using EEPROM instead of switches; there is no visual indication of the setup information in the module. It is impossible to tell just by looking at the module what the baud rate, address, parity and other settings are. It is difficult to establish communications with a module whose address and baud rate are unknown. To overcome this, each module has an input pin labeled DEFAULT*. By connecting this pin to Ground, the module is put in a known communications setup called Default Mode.
The Default Mode settings are: 9600 baud, one start bit, eight data bits, one stop bit, no parity, any address is recognized. The module will answer to address “01” in the Default Mode.
Grounding the DEFAULT* pin does not change any of the setups stored in EEPROM. The setup information may be read back to determine all of the setups stored in the module.
Setup information in a module may be changed at will in the Default Mode. The baud rate and parity setups may be changed without affecting the Default Mode values of 9600 baud and no parity. When the DEFAULT* pin is released, the module automatically performs an internal reset and configures itself to the baud rate and parity stored in the setup information.
The Default Mode should only be used with a single module connected to a computer for the purpose of identifying and modifying setup values. In most cases, a module in Default Mode may not be used in a string with other modules.
Communications Connections
The D6000 series module must be connected to a host computer with an RS-485 serial port for configuration. For computers that contain an internal RS-232 port then the A1000 RS-232 to RS­485 serial converter can be used to connect the module to a computer. For computers without internal serial ports then a USB to RS-485 converter can be used to connect the module to a computer. The RS-485 serial connections for both devices are detailed below.

DEFAULT Mode Connection
For simplicity, we recommend performing all the setups while in the Default Mode. Place the D6000 in Default Mode by connecting the DEFAULT* terminal to the GND terminal using a jumper wire. When the module is in the Default Mode the serial parameters are internally set to: 9600 Baud, 8 data bits, no parity and one stop bit. The module will respond to Modbus Slave address “01”.
Note: No other wiring connections are required on the analog or digital I/O pins to perform the module configuration.
1.1 Getting Started
The first step towards “Getting Started” with your D6000 series module is to connect the module to an RS-485 serial port using the wiring connections above. Included within the wiring connections is the “Default*” line being connected to the power supply ground. This connection places the module in the “Default Mode”. The Default Mode forces the module into a known communications state and is best utilized for configuring the module. The Default Mode serial communications parameters are: 9600 baud, eight data bits, no parity and one stop bit. The module will answer to Modbus Slave address “1” (0x01).
The D6000 series modules require a software program to change the setup register values. Since the modules communicate via the Modbus RTU protocol, a Modbus Master program or the D6000 series Utility Software will be required to change the module configuration.
The D6000 Series Utility Software is the best program to use when configuring a module. The utility software reads the module information, displays the information in easy to understand terms, allows changes to be made via drop-down list boxes and then writes the new values back to the module. The module parameters can also be stored to disk and recalled at a later date.
The D6000 series Utility Software is provided free of charge on CDROM with a purchase order and the latest version is always downloadable from www.omega.com. The utility software runs on Windows based computers. Simply insert the CDROM into the CDROM drive, or download the Setup.Exe file from the website, and then run the SETUP.EXE installation file. The software will install and create a menu section called “Omega Utility Software” and the Utility Software will be under that selection.
From the computer desktop select the “start” button, select “all programs”, select “Omega Utility Software” and then select “D6000 Series Utility Software” to run the utility software. When the software opens the first step is to select, configure and open the host serial communications port where the module is connected.

Page 8
Select the “Serial Port” connection type in the upper left corner of the program screen and then select the proper communications port in the upper right hand corner of the screen. Next, press the Serial Port “Settings” button.
If the “Default*” line is connected to ground then select 9600 baud, no parity, eight data bits, one stop bit, RTS Only handshaking and the Tx and Rx delays can be left in their default state. Otherwise, adjust the communications settings to match the settings in the connected module.
Press the “Open Port” or “Update” button to complete the serial port configuration process.
Test Communications
After the utility software serial port has been configured the next step would be to check for valid communications between the computer and the module. You must have valid communications with the module before trying to perform the configuration process. To test the communications,
6
Page 9
set the Modbus Address to 01 in the “Default Mode” or set the Modbus Address to match the setting in the module. Set the Function selector to 03 and the Register selector to 40001. Press the “Send” button to verify communications. A module response will be shown in the figure below.
The figure above illustrates the Modbus function 03 being sent to Modbus Slave address 01. Both the command and response messages are displayed beginning with CMD and RSP respectively. This display format is provided for troubleshooting purposes as it displays each byte of information being sent to and received from the module. This format can be a good troubleshooting tool or a way to become familiar with the formatting of the Modbus RTU protocol.
The response data value from register 40001 is located in the RSP: line. The data value returned is a 16-bit value located in the fourth and fifth bytes in the message (00 01). The “00 01” indicates that the register value is 0001. From the 7CH Current Input Modbus Register map, register 40001 is the Modbus Slave address value. In the case the module slave address value is read back as
0001. In the event that the module was not detected by the software then the RSP: line would say
“RSP: Timeout – No Response Detected!”. Several things can contribute to this problem. Some examples are no power to the module, bad RS-485 wiring connection(s), invalid port settings, or RS-485 half-duplex handshaking problems all can cause timeout errors. Timeout errors must be corrected before attempting to configure a module.
Setup a Module
After a successful communications test has been performed then the module can be configured. Select the type of module using the drop-down list box under “Quick Setup” in the lower left hand corner of the screen. Then press the “Setup” button. A new screen (see below) will appear that contains list of all the user-selectable module values. Several different screens can appear. Each screen is specific to the type of module connected. The screen below is for a seven channel current input module.
7
Page 10
Ensure that the Module Address in the lower left corner is 01 and then press the “Read Setup” button. The screen will now populate with the existing configuration data inside the module.
The user-selectable values will be displayed in an easy to understand format and new selections can be made using the drop-down list boxes. The drop-down list boxes make the configuration process easy and accurate because erroneous values cannot be entered.

Page 11
Once the new module configuration settings have been changed to meet the application requirements then press the “Apply” button to transmit the new settings.
Scan Module Data Values
After the module has been properly configured, the analog input module configuration screens can poll modules in order to verify the data from each channel. This feature is a good troubleshooting or verification tool when the analog input signals are physically connected to the module.
The analog input screens contain a “Scan” button that will start the scanning process. Each data channel is read by requesting the data values from data registers within the module. The analog input data registers can be found in the Modbus Register map and the data register locations are specific to the module type.
The data values are returned in hexadecimal percentage of Full Scale format where a value of 0x0000 represents the minus full scale input of the module. A value of 0xffff represents the positive full scale input of the module. These values can be used as check to ensure that the channels are operating properly when analog input signals are applied to the input terminals.
The data values can also be displayed as a numerical value. The utility software knows the plus and minus full scale input limits for each channel. Using the raw hexadecimal percentage of full scale data values the software can convert these readings to millivolts, milliamps, or temperature readings. Simply uncheck the “Display Hex Values” selection underneath the channel readings to display the numeric values.
The scanning process will also log and display the highest (peak) and lowest (valley) readings that were recorded during the scanning process. This is just for indication purposes only.
A scan interval slide control is also provided to speed up or slow down the scanning process. This slide control allows the channels to be scanned at intervals from 0.5 to 5 seconds.

3.0 Communications
Each D6000 series module contains a two-wire RS-485 serial interface for communications. The RS-485 communications standard was developed to satisfy the need for multi-dropped systems that can communicate at high data rates over long distances. RS-485 is similar to RS-422 in that it uses a balanced differential pair of wires switching from 0 to 5V to communicate data. RS-485 receivers can handle common mode voltages from -7V to +12V without loss of data, making them ideal for transmission over great distances. RS-485 differs from RS-422 by using one balanced pair of wires for both transmitting and receiving. Since an RS-485 system cannot transmit and receive at the same time it is inherently a half-duplex system.
RS-485 offers many advantages:
1) balanced line gives excellent noise immunity
2) can communicate with modules at high baud rates
3) communicate at distances up to 4,000 feet.
4) true multi-drop configuration as the modules are connected in parallel
5) individual modules may be disconnected without affecting other modules
6) up to 32 modules on one segment of the communications line; 247 with repeaters
7) simplified wiring using standard telephone cable Figure 2.0 below illustrates the wiring required for multiple-module RS-485 system. Notice that
every module has a direct connection to the host system. Any number of modules may be unplugged without affecting the remaining modules. Each module must be setup with a unique address and the addresses can be in any order. Also note that the connector pins on each module are labeled with notations (B), (R), (G), and (Y).
Figure 2.0 Typical RS-485 Serial Communications System Architecture
This designates the colors used on standard 4-wire telephone cable: (B) GND Black Wire
(R) V+ Red Wire (G) DATA* Green Wire (RS-485 DATA-) (Y) DATA Yellow Wire (RS-485 DATA+)
This color convention can be used to simplify installation. If standard 4-wire telephone cable is used, it is only necessary to match the labeled pins with the wire color to guarantee correct installation. The RS-845 data lines are designated on the label as DATA* and is the complement of DATA (negative true). To minimize unwanted reflections on the transmission line, the bus
10
Page 13
should be arranged as a line going from one module to the next. ‘Tree’ or random structures of the transmission line should be avoided. For wire runs greater than 500 feet, each end of the line should be terminated with a 220 ohm resistor connected between DATA and DATA*.
When using a bi-directional RS-485 system, there are unavoidable periods of time when all stations on the line are in receive mode. During this time, the communications lines are left floating and are very susceptible to noise. To prevent the generation of random characters, the lines should be biased in a MARK condition as shown in Figure 2.0. The 1K resistors are used to keep the DATA line more positive than the DATA* line when none of the RS-485 communications transmitters are on.
When enabled, the low impedance of an RS-485 driver easily overcomes the load presented by the resistors. Special care must be taken with very long busses (greater than 1000 feet) to ensure error-free operation. Long busses must be terminated as described above. The use of twisted cable for the DATA and DATA* lines will greatly enhance signal fidelity.
In situations where many modules are used on a long line, voltage drops in the power leads becomes an important consideration. The GND wire is used both as a power connection and the common reference for the transmission line receivers in the modules. Voltage drops in the GND leads appear as a common-mode voltage to the receivers. The receivers are rated for a maximum of -7Vdc of common-mode voltage. For reliable operation, the common mode voltage should be kept below -5V. To avoid problems with voltage drops, modules may be powered locally rather than transmitting the power from the host.
Inexpensive ‘calculator’ type power supplies are useful in remote locations. When local supplies are used, be sure to provide a ground reference with a third wire to the host or through a good earth ground. With local supplies and an earth ground, only two wires for the data connections are necessary.

4.1 D6100 - Seven Channel Voltage Input Module
Overview
The D6100 series analog input modules contain seven differential analog inputs that can measure six different DC voltage ranges. Each analog input channel is user programmable and may be assigned to measure a different range. Any unused channels can be disabled.
Analog to Digital Converter
The D6100 series analog input modules contain a 16-bit analog to digital converter to perform the signal conversion to digital information. The analog to digital converter performs a total of 25 conversions per second. Meaning, if all 7 channels were enabled the each channel would be measured 3+ times per second. The conversion rate per channel can be improved by disabling any unused channels.
Features and Register Assignments
The D6100 series analog input modules contain many user-selectable features. The user can select all features such as baud rate, parity type, analog range selection and digital filtering. The complete list of features is illustrated in the “Seven Analog Voltage Input Register Assignments register map below. The register map format is used for consistency with the Modbus RTU protocol. The register map contains the register numbers in decimal format, register description, acceptable data values, and list of what each value means. These registers can be written to using most any Modbus master program or using the D6000 series utility software.
Note: All Modbus Register values in the tables below are represented as “decimal” numbers.
Factory Initial Values
The D6100 series analog module features are initialized at the factory with a set of “Initial Values”. A complete list of factory “Initial Values” can be found in the table below. For reference purposes, the Modbus Slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None and the Stop Bits is “1”.
Calibration
The D6100 series analog input modules are shipped from the factory as fully calibrated devices. Throughout the lifetime of the module there may be need to verify or adjust the calibration of the device. The verification and adjustment process should only be completed using NIST traceable calibration equipment. A D6100 series Calibration procedure is included below.
Connector Pin Designations
The D6100 series module uses two 3.81mm removable plugs for connecting signals to the module. One six-pin connector is for the power supply and the host RS-485 data line connections. A second sixteen-pin connector is used to connect analog input signals to the module. The pin designations for each connector are printed on the module label and are listed in a table below.

4.2 D6200 - Seven Channel Current Input Module
Overview
The D6200 series analog input module contains seven differential analog inputs for measuring current signals such as 4-20mA loops. Each analog input channel can measure current signals up to +/-20mA. Any unused channels can be disabled.
Analog to Digital Converter
The D6200 series analog input modules contain a 16-bit analog to digital converter to perform the signal conversion to digital information. The analog to digital converter performs a total of 25 conversions per second. Meaning, if all 7 channels were enabled the each channel would be measured 3+ times per second. The conversion rate per channel can be improved by disabling any unused channels.
Features and Register Assignments
The D6200 series analog input modules contain many user-selectable features. The user can select all features such as baud rate, parity type, analog range selection and digital filtering. The complete list of features is illustrated in the “Seven Channel Analog Current Input Register
Assignments” register map below. The register map format is used for consistency with the
Modbus RTU protocol. The register map contains the register numbers in decimal format, register description, acceptable data values, and list of what each value means. These registers can be written to using most any Modbus master program or using the D6000 series utility software.
Note: All Modbus Register values in the tables below are represented as “decimal” numbers.
Factory Initial Values
The D6200 series analog module features are initialized at the factory with a set of “Initial Values”. A complete list of factory “Initial Values” can be found in the table below. For reference purposes, the Modbus Slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None and the Stop Bits is “1”.
Calibration
The D6200 series analog input modules are shipped from the factory as fully calibrated devices. Throughout the lifetime of the module there may be need to verify or adjust the calibration of the device. The verification and adjustment process should only be completed using NIST traceable calibration equipment. A D6200 series Calibration procedure is included below.
Connector Pin Designations
The D6200 series module uses two 3.81mm removable plugs for connecting signals to the module. One six-pin connector is for the power supply and the host RS-485 data line connections. A second sixteen-pin connector is used to connect analog input signals to the module. The pin designations for each connector are printed on the module label and are listed in a table below.

4.4 D6400 - Seven Channel Voltage, Thermocouple, Current Input Module
Overview
The D6400 series analog input module contains seven analog inputs for measuring voltages, thermocouples and current. Each analog input channel is user programmable and may be assigned to different input types.
When measuring voltages or thermocouples, simply use the Utility Software to select the type of signal and range. When configuring any channel to measure current loops or 4-20mA signals then the Input range can be set to either the +/-1Vdc or +/-20mA selections. The module uses the +/-1Vdc range to measure current up to 20mA.
When measuring current signals then a measurement sense resistor must be enabled via jumpers inside the module. Each channel has a jumper strip that must be shorted using a provided shorting bar to enable the sense resistor. The sense resistor is internally connected directly across the channel+ and channel- input pins. See the D6400 board layout below for instructions on taking the module and enabling the jumpers.
Analog to Digital Converter
The D6400 series analog input modules contain a 16-bit analog to digital converter to perform the signal conversion to digital information. The analog to digital converter performs a total of 25 conversions per second. Meaning, if all 7 channels were enabled the each channel would be measured 3+ times per second. The conversion rate per channel can be improved by disabling any unused channels.
Features and Register Assignments
The D6400 series analog input modules contain many user-selectable features. The user can select all features such as baud rate, parity type, analog range selection and digital filtering. The complete list of features is illustrated in the “Seven Channel Voltage, Thermocouple and Current
Input Register Assignments” register map below. The register map format is used for consistency
with the Modbus RTU protocol. The register map contains the register numbers in decimal format, register description, acceptable data values, and list of what each value means. These registers can be written to using most any Modbus master program or using the D6000 series utility software.
Note: All Modbus Register values in the tables below are represented as “decimal” numbers.
Factory Initial Values
The D6400 series analog module features are initialized at the factory with a set of “Initial Values”. A complete list of factory “Initial Values” can be found in the table below. For reference purposes, the Modbus Slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None and the Stop Bits is “1”.
Calibration
The D6400 series analog input modules are shipped from the factory as fully calibrated devices. Throughout the lifetime of the module there may be need to verify or adjust the calibration of the device. The verification and adjustment process should only be completed using NIST traceable calibration equipment. A D6400 series Calibration procedure is included below.
Connector Pin Designations
The D6400 series module uses two 3.81mm removable plugs for connecting signals to the module. One six-pin connector is for the power supply and the host RS-485 data line connections. A second sixteen-pin connector is used to connect analog input signals to the module. The pin designations for each connector are printed on the module label and are listed in a table below.

4.4.6 D6400 Current Channel Enable: Overview
The following information details how to open the D6400 module and enable or disable current channels.
Default from the Factory
No current enabling jumpers are installed at the factory. All channels are initialized as voltage inputs.
Open the Module
Remove the top cover of the D6400 module by unscrewing the four screws on the top cover. With the cover removed, locate J100, a storage strip that contains up to seven unused jumpers. Then locate the CH1 through CH7 jumper strips that enable current channels.
Move the Jumpers
To enable any channel as a current input channel, simply move a jumper from J100 to the specific channel jumper strip. To disable a current input channel, simply move the jumper from the channel jumper strip back to J100. See the image below for the location of the pin strips versus channels.

4.5 D6500 Two Channel Analog Output Module
Overview
The D6500 series analog output module contains two 12-bit analog outputs for controlling process control devices. Each analog output signal can be configured as either a voltage or current output. Two voltage ranges and two current ranges can be selected for maximum flexibility to control many different process control devices.
Analog Outputs
The D6500 series analog outputs can be configured as either voltage outputs or current outputs.
Features and Register Assignments
The D6500 series modules contain many user-selectable features. The user can select all features such as baud rate, parity type, power-on “safe” analog output value and communications watchdog timer interval. The complete list of features is illustrated in the “Two Channel Analog
Output Register Assignments” register map below. The register map format is used for
consistency with the Modbus RTU protocol. The register map contains the register numbers in decimal format, register description, acceptable data values, and list of what each value means. These registers can be written to using most any Modbus master program or using the D6000 series utility software.
Note: All Modbus Register values in the tables below are represented as “decimal” numbers.
Factory Initial Values
The D6500 series analog output modules are initialized at the factory with a set of “Initial Values”. A complete list of factory “Initial Values” can be found in the table below. For reference purposes, the Modbus Slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None and the Stop Bits is “1”.
Communications Watchdog Timer
The D6500 series digital output module contains a user-programmable communications watchdog timer. The communications watchdog timer can be used to force the analog output signals to a known “safe” condition in the event that communications are lost to the module. The known “safe” condition can be user-programmed into the module Initial Value register.
Connector Pin Designations
The D6500 series module uses two 3.81mm removable plugs for connecting signals to the module. One six-pin connector is for the power supply and the host RS-485 data line connections. A second eight-pin connector is used to connect analog output signals to control devices. The pin designations for each connector are printed on the module label and are listed in a table below.

4.7 D6720 - Fifteen Bit Digital Output Module
Overview
The D6720 series digital output module contains fifteen digital outputs for controlling process control devices such as relays, lamps, annunciators and other ON/OFF devices.
Digital Outputs
The D6720 series open-collector digital outputs can be pulled up to +30Vdc max and each bit can sink up to 100mA. The open-collector output provides maximum flexibility to control many different process control devices.
Features and Register Assignments
The D6720 series digital output modules contain many user-selectable features. The user can select all features such as baud rate, parity type, power-on bit state and communications watchdog timer interval. The complete list of features is illustrated in the “Fifteen Bit Digital I/O
Register Assignments” register map below. The register map format is used for consistency with
the Modbus RTU protocol. The register map contains the register numbers in decimal format, register description, acceptable data values, and list of what each value means. These registers can be written to using most any Modbus master program or using the D6000 series utility software.
Note: All Modbus Register values in the tables below are represented as “decimal” numbers.
Factory Initial Values
The D6720 series digital output modules are initialized at the factory with a set of “Initial Values”. A complete list of factory “Initial Values” can be found in the table below. For reference purposes, the Modbus Slave address is preset to hex 0x01, the baud rate is 9600, Parity type is None and the Stop Bits is “1”.

5.0 Modbus Protocol
The D6000 series modules utilize the Modbus RTU protocol for communications. The Modbus RTU protocol is widely supported protocol supported by almost all commercial data acquisition programs and programmable controllers in the marketplace. This allows for easy connection of a D6000 series module to an existing system or new application.
The D6000 series modules utilize up to eight different functions from within the Modbus RTU protocol. The number of functions utilized by a module depends on the model type and the features it contains.
The Modbus functions allow users to control every function within a module. The functions and their descriptions are listed below. Each function is also outlined in further detail below.
Function Description
