INTRODUCTION
General Information
Chapter 1: Introduction to the WB-DynaRes
Thank you for selecting the WB-DynaRes board for your project! Our primary objective is to provide you with data acquisition systems that
are easy to install, operate, and maintain. W e also strive to furnish the perfor­mance you need at the lowest overall cost. The benefits for you are increased productivity, data you can count on, and, of course, meeting your budget.
We manufacture the WB-DynaRes as an enhancement board that readily mounts in an expansion slot in an IBM PC, or -compatible, computer.
This product’s high noise rejection, its input protection to withstand as much as 150 Volts, and its guaranteed long term stability make it ideal both for the laboratory and for harsh industrial environments.
Using the WB-DynaRes board together with our graphical interface applica­tion software (such as WorkBench PC, or QuickLog PC), you can easily and very quickly implement a broad spectrum of research and commercial tasks, in a wide variety of settings. You can, for example,
· Display and log data
· Measure temperature, pressure, flow
· Perform scale, offset, or complex calculations
· Monitor and control processes
· Set alarm limits
· Control devices at preset levels
· Control devices from digital input
· Gather data unattended
You can use the system interactively, operating controls or modifying your setup while the system is running.

(rather than using an off-the-shelf application) can employ the Analog Connection Development System hardware driver to ad­dress all features of the WB-DynaRes board from within a pr ogram they design and code for their specific purpose.
A WB-DynaRes product, depending on the model, has either eight or 16 differential analog input channels; and you can add one board at a time to your computer , up to as many as 15 boards, with a total of 240 analog input channels and 240 digital input/output lines!
The six input ranges of the WB-DynaRes span from 25 milliVolts
UNITS OF MEASURE
through 10 Volts, capable of accepting data from almost any sen­sor. Its high accuracy also makes the WB-DynaRes ideal for pr ecise measurement in the laboratory.
The WB-DynaRes together with our software – such as Work­Bench PC and QuickLog PC – make it easy to specify engineering units (degrees, Volts, milliAmperes, etc.) for measurements, as well as which ranges to use.
You can measure temperature, for example, by selecting from among 11 different thermocouple types, or from a wide variety of resistance temperature detectors – RTDs. With our application software, the process simply consists of selecting the type of sens­ing device from a menu – the driver automatically handles cold junction compensation and linearization.
PRESENTATION
RESOLUTION
Chapter 1 Introduction
1 – 2
The combination of our hardware and application software (W orkBench PC or QuickLog PC) enables both the display of data on the screen, and the logging of data to disk for later analysis.
The system is capable of showing data on the monitor in a variety of formats, including graphical meters. Charts can indicate trends for comparison of actual measurements on several channels, or for setting data points or alarms.
Your WB-DynaRes incorporates “Dynamic Resolution,” improv­ing the board’s accuracy.
With this feature, resolution is greater at the lower (negative) end of any range than at the higher end. As your readings approach the low end of any given range, the resolution becomes finer (that is, the increments of the signal you can distinguish become smaller).
Page 8
INTRODUCTION
General Information
This feature allows you to obtain the same advantages of an inte­grating converter, with the speed of a sample and hold converter, but without its susceptibility to noise.
Dynamic resolution gives a resolution that is a fixed percentage of the input voltage (not full scale voltage) down to about 10% of full scale. Our products, consequently, are the best available for taking accurate measurements of low-level signals, as you would using a thermocouple sensor.
Dynamic resolution is always best toward the negative end of any range:

urations, also depending on the model of the product: The WB­DynaRes 8 and the WB-DynaRes 8 Ultra feature eight differential analog inputs, and the WB-DynaRes 16 and WB-DynaRes 16 Ultra models offer 16 differential analog inputs.
The resolution of your WB-DynaRes is selectable in software, ranging from 10 through 12 bits for the WB-DynaRes 8/16, and from 12 through 16 bits for the WB-DynaRes 8/16 Ultra.
(The WB-DynaRes also features advanced “dynamic resolution.” See page 1 – 2 for further explanation.)
Maximum acquisition rates for the WB-DynaRes 8/16 range up to 1700 Hz, while the WB-DynaRes 8/16 Ultra is capable of reading

data up to 900 Hz. WB-DynaRes products have six voltage ranges, all selectable indi-
vidually for each analog input channel.
REJECTION
PROTECTION
Chapter 1 Introduction
1 – 4
All WB-DynaRes models feature a high noise rejection integrating converter (in “low noise mode” it helps reject 50/60 Hz AC power line interference).
Each WB-DynaRes provides accurate cold junction compensation and linearization for thermocouple devices, and signal condition­ing for resistance temperature detectors (RTDs).
We guarantee the factory calibration of the WB-DynaRes for a period of two years from the date of purchase. (If it is ever neces­sary, the user can recalibrate the board with precision through the use of software utilities we provide with every product.)
Built-in circuitry assures protection of analog input channels for 50 Volts, continuous , or 150 Volts, momentary.
There are 8 digital input/output channels on the WB-DynaRes 8 and WB-DynaRes 8 Ultra models; 16 digital I/Os are available on the WB-DynaRes 16 and WB-DynaRes 16 Ultra.
Every WB-DynaRes board includes a counter/timer for precise timing (for counting pulses or other events) which you can also

use as a pulse output. (
NOTE: If you are using WorkBench PC for Windows, the counter/timer of the first board installed will not be available for use.
)
Available accessories for the WB-DynaRes include your choice of screw terminal panels for connecting sensors. They include gener­al purpose, thermocouple, and resistance temperature detector (RTD) device terminal panels, all of which accept digital opto-iso­lators.
For more information about the capabilities of your WB-DynaRes, please see “Product Specifications” in Chapter 3.
For instructions on controlling the board with our interface soft­ware (such as WorkBench PC or QuickLog PC), refer to the appropriate software manual.
To learn more about data acquisition and process control in gen­eral, and how to use our products together to accomplish every­day tasks, consult our

Overview
· Physically insert the board
(page 2 – 4; and illustration on 2 – 3),
· Connect a terminal panel to the board
and for digital outputs from the WB-DynaRes; see page 2 – 4), and
· Load and start up the software
As the scope of this manual focuses on the WB-DynaRes board, this chapter discusses board’s switch settings, and the physical insertion of the board.
Please see your terminal panel manual for full instructions regarding its attachment to the WB-DynaRes, as well as for how to connect sensors to the panel.
Guidelines for loading the software, and for starting up, depend on the application program you are going to use (such as our WorkBench PC for Windows or DOS, or QuickLog PC, or a package by a third party developer who has our authorization).
The program you are going to use with the WB-DynaRes might even be unique and proprietary, a product of your organization. (The Analog Con­nection Development System is a powerful set of utilities making it possible for software engineers to design and develop their own programs to exploit the WB-DynaRes’ many features.)
In any event, please refer to the software provider’s installation manual, or user guide, for specific information on how to load and run the particular program.

Verifying Switch Settings

Verifying WB-DynaRes Switch Settings

When you purchase a data acquisition board new from our com­pany, the product’s switch settings already are correct to operate a
single
board with our software (WorkBench PC, QuickLog PC, the
Analog Connection Development System, and all others). This means the factory switch settings are right for the purpose of
using only one board, and you can skip the task of confirming them. You can go directly to the “Physical Board Installation” sec­tion on page 2 – 4 in this chapter, and begin to follow the steps there.
If you are using more than one board at a time, set the individual
BOARDS
IN USE
boards’ Board Number Switch first (refer to “Setting the Board Number Switch” on page 2 – 6), then go on to perform the phys­ical installation.
Otherwise, there’s no reason to be concerned about the board’s switch settings, except in the unlikely event you encounter a problem in getting your product to operate. (If you experience a problem, refer to “Troubleshooting” in Chapter 3).
If, on the other hand, your board has been in use previously in another computer, or if your company uses its own proprietary software, the present switch positions might differ from the fac­tory settings.

Physical Board Installation

Installation very simply consists of inserting the board into an open peripheral (expansion) slot inside your computer.
(There are, for example, five available slots in the IBM PC, and eight in the IBM XT or AT. IBM and other companies sell expan­sion chassis that can accept even more analog cards. Our software supports as many as 15 boards at one time.)
When using a terminal panel with the WB-DynaRes (to connect
CONNECTIONS
external devices: sensors and digital input/output) you are going to use the provided Centronics cable.
Each cable can conduct eight analog input channels and eight digital I/O lines from your WB-DynaRes to a single terminal panel.
One T erminal Panel, One Cable –
Ultra, using eight analog input channels, requires one Centronics cable for connection to one terminal panel (this also allows the use of eight digital I/O lines).

4.
Remove
Plate
At the back panel of the computer, unscrew and remove the narrow dust cover plate that is directly behind the expansion slot you want to use. (Keep this screw handy.)
5.
Insert the Board
Push the edge of the WB-DynaRes board hav­ing “gold fingers” down and into the expansion slot (socket) on the chassis, making sure that the contacts align with the socket and the spring latches are through the socket. Then plug it in by pushing the board straight down. (NOTE: If you
are using a WB-DynaRes 16 or WB-DynaRes 16 Ultra, a second expansion slot is required for the second cable connector.)
6.
Fasten the Board to the Chassis
Install the “left over” screw from step 4. Place it in the original hole, through the WB-DynaRes board’s bracket, so that it fastens the top of the bracket to the computer’s back panel.
7.
Connect the Cable to the Terminal
Panel
Plug the cable’s connec­tor into the socket on the terminal panel (please refer to your terminal panel’s manual, if you are unsure about the correct position).
Incorrect installation of these cables can damage the data acquisition board or the terminal panel. If you are uncertain about proper placement, please see “Terminal Panel Connec­tions” at the beginning of this discussion, and inspect the dia­gram on page 2 – 3 .)
IMPORTANT! Measuring Current –
If you are going to measure cur-
rent, please see “Measuring Current” on the next page.
Single Board Usage –
If you intend to run with a single data acquisition board in your system, you are now ready to install your applica­tion software and to connect sensors to your terminal panel.
Multiple Board Usage –
If you are going to use more than one data acquisition board, now it’s time to set each Board Number Switch to an unique number. Follow the steps in the “Setting the Board Number Switch” section in this chapter on page 2 – 6.
Installing the Software –
For information on loading and configur­ing our WorkBench PC for Windows or DOS or QuickLog PC please refer to the user guide for that application package.

Measuring Current
If you are going to connect a current, rather than a voltage, to one or more of the analog input channels, then make certain to set the “Current/Volt” switch for that channel on the terminal panel. These switches are located under the daughterboard on the WB­T71 terminal panel (see Terminal Panels manual for illustration) .
Moving a switch to the “Current” position selects current, placing a precision 24.9 Ω , 0.1% resistor in the circuit for that channel.
Two kinds of misuse can burn out the board’s input sense resistors:
Do not apply a voltage to a channel whose setting is for current. Also, do not apply more than 50 mA to a channel set for current.

Setting the Board Number Switch

When you are using multiple boards in your installation, each board needs to have an identity for the software to recognize it as an “individual.”
The Board Number switch on a board accomplishes this, as it enables you to set an identifying number for the board (see the illustration on page 2 – 3).
This number determines, among other things, the sequence in which the software reads multiple boards (OMEGA programs can address as many as 15 boards).
When using more than one WB Series product in your installa­tion, every board’s Board Number switch needs to have a different

SETTING

number setting, and all switches are to be in number sequence, starting with 1. For example, if you are using three boards, the board number sequence would be 1, 2, 3.
(If there are also WB-Flash-12 or WB-WorkMate boards in your installation, and you are using DOS software, then their Board Numbers need to be at the high end of the number sequence.)
If your system includes just a single data acquisition board, then you don’t need to have much concern about the Board Number switch.
When your WB-DynaRes leaves our manufacturing facility, we set the Board Number switch to 1, and this is the setting we recom­mend for most purposes when you are using only one board in your installation.
If you want to disable the board, for any reason, set its Board Number switch to 0. This is handy if you want to use fewer boards for a while: that way you don’t have to r emove them from the computer. Remember, however, that all remaining boards must have their board numbers in a continuous sequence.
THE SWITCH
To Set the Board Number Switch –
1.
Locate
the Switch
With the cover of your computer removed, examine the illustration on page 2 – 3 in this chapter and find the “Board Number Switch” on the WB-DynaRes.
On the printed circuit board, this is a rotary switch with the label “BRD SEL.”
2.
Make
the Setting
Note that the switch has 16 possible posi­tions: numbers on the detents are 0 through 9 and A through F.
Determine which is to be the First Board. (This is easy, if it is the sole board.) Then turn its dial to 1.
Determine which is to be the Second Board, then set its switch to 2.
Continue to set the switches for all boards in your installation to unique numerical values in an unbroken sequence.
(As various models of our boards use different kinds of
switches, please see their owner’s manuals for an explanation of how to set switches on other boards.)

Setting the Base Address

Setting the Base Address
The Base Address determines the logical system address where the personal computer expects to find all data acquisition boards. Base Addresses must be the same
The factory setting for all of our data acquisition products is 300H (in hexadecimal format).
It is rarely necessary, but if you have difficulty getting the board to work you can change these switches to values different from the factory settings. (Another device in your PC, for example, might be trying to use the same Base Address.)
Indications of this are: if the program reports it cannot find your board, or if it reports fewer boards than you really have, or if another board starts to work improperly after you install the WB­DynaRes.
These problems indicate interference with another board using the same base address as the WB-DynaRes product.
Remedy the problem by changing the switches of all data acquisi­tion boards to an address that has no conflict. (If you have boards other than WB-DynaRes in your system, please refer to their owner’s manuals for instructions on how to change their sett­tings.)

METHODS

RECALIBRATION

TECHNICAL NOTES
Recalibration
Recalibration
Your WB-DynaRes uses an exclusive calibration technology to achieve great stability, requiring no adjustment for years. (As a reflection of this, we guarantee the factory tolerances for two years from the date of purchase.)
Instead of employing adjustment potentiometers to calibrate the board, our technicians test and calibrate each WB-DynaRes after assembly. They then enter that board’s unique calibration number values into EEPROMs on the board; we also print the same num­bers on a label on the board itself.
Whenever you use our software with the board thereafter, the programs read the factory’s calibration numbers from the EEPROM, and automatically make minor compensations for real­world conditions (for instance, for cold junction properties of a thermocouple).
Under normal conditions, no full recalibration of the WB­DynaRes is necessary.
(If you ever suspect that your WB-DynaRes is out of tolerance, please call Technical Support for advice. If it requires recalibra­tion, we can perform the work for you at our facility using the same high accuracy test equipment we use during the manufac­turing quality assurance process.)
A Note About RECAL.EXE –
on the QuickLog PC disk, RECAL.EXE, is for the purpose of completely recalibrating our data acquisition boards. This soft­ware, however, is only suitable for use in a comprehensive hard­ware lab, and requires sophisticated test equipment.
(Successful use of RECAL.EXE requires, for example, a precision DC voltage supply, as well as a digital volt meter having 0.005% accuracy.)
Only if your organization is proficient in such techniques, and only if you have the necessary equipment, do we encourage you to proceed with recalibration (and please contact our Technical Support Department for guidelines).
For most customers, we recommend returning the board to our Technical Services Department, instead.

the Address Latch Enable (ALE) timing is not compatible with our data acquisition boards.
To try the alternate (falling edge) timing, locate jumpers JP5 through JP8 on the data acquisition board. The normal (rising edge) timing position is JP6 and JP8. To change this, you need to cut these traces with a sharp knife, then solder a wire across JP5 and JP7.
(NOTE: This alternate connection may not work in all mod­els of computers.)
(Please call our Technical Support line before returning a board – we hope to assist you with your problem via telephone.)

Troubleshooting: Operation
During operation, it’s good practice to short all analog input channels you’re not using; to do this, connect + to – to Com.
It’s essential to have exactly one ground reference per channel. This single connection to ground makes sure you don’t exceed the common mode range of input.
Qs AND As
Chapter 3 Technical Notes

(More than one connection per channel can lead to ground loops, causing errors or erratic readings. Connecting the – to the Com terminal provides a single ground. Your sensor might also pro­vide another ground. If you’re not sure that your sensor is grounded, try connecting the – to Com, and not, and see which works best.)
Remember that if speed is not critical, selecting the “low noise mode” in software always provides the best accuracy and resolu­tion with your data acquisition board.

Same as General Conditions. Does not include the accuracy of the RTD sensor itself. Includes linearization and signal conditioning errors. Resolution assumes 12 bit resolution is in use. RTD measurements are on the 50 mV range.
Accuracy
°C.
Accuracy specifications in this chapter already reflect these tem­perature drift errors for temperatures from 20° through 40° C.:
WB-DYNARES 8/16 STABILITY –
Range % of °C. % Over a Year
50 mV ± 0.001 ± 0.02
± 25mV ± 0.001 ± 0.02
all other voltage ranges ± 0.0025 ± 0.03
In many applications, stability and noise can be more important than absolute accuracy. This is “repeatability.” Calculate the repeatability of a reading by adding together the stability and noise for the range you want.
The WB-DynaRes 8/16 has an input impedance of > 20 M Ω.

* Rates describe an IBM PC 486DX2 66MHz running WorkBench PC for Windows under Windows 3.1 with Tol­erate Error=0. Rates are somewhat faster in faster comput­ers. Please also see “Dynamic Resolution” on page 1 – 2.
Scan Rate –
Scan rate is the rate in Hertz (or, samples per second) to read data into memory, including the time it takes to switch channels and ranges. To calculate the total scan time for all chan­nels, divide the rate by the number of channels.
