Our primary objective is to provide you with data acquisition systems that are easy to install, operate, and maintain. We also strive to furnish the perfor- mance 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-AVO as an enhancement board that readily mounts in an expansion slot in an IBM PC, or -compatible, computer. This product’s guaranteed long term stability make it ideal both for the labo- ratory and for harsh industrial environments. Using the WB-AVO together with our graphical interface application software (such as WorkBench™ PC for DOS or Windows, or QuickLog™ PC), you can easily and very quickly implement a broad spectrum of research and commer- cial tasks, in a wide variety of settings. You can, for example, · Ramp, hold, or step analog outputs, · Control processes with proportional or on/off control, · Set alarm on any digital input, · Control devices at preset levels (fans, pumps, heaters, etc.), · Control devices from digital input (e. g., from switches or TTL signals), and · Control processes unattended. You can use the system interactively, operating controls or modifying your set- up while the system is running. DEVELOPMENT People who decide, on the other hand, to write their own software (rather SYSTEM than using an off-the-shelf application) can employ the Analog Connection WB-AVO Operator’s Manual 1 – 1 WB-AVO OWNER’S MANUAL General Information Development System™ hardware driver to address all features of the board from within a program they design and code for their specific purpose. EXPANDABILITY The WB-AVO has either two or eight analog output channels and eight digital input/output lines; and you can add one board at a time to your computer, for as many as 15 boards with a total of 120 analog output channels and 120 digital I/Os! In addition, sep- arate analog input cards may be used with the same software. RANGES/ The WB-AVO features switch-selectable ranges of 0-10V, 0-5V, or UNITS OF OUTPUT ±5V for voltage output, and 4-20mA for current output. Self-cali- bration and self-diagnostics are built into the board to ensure that the output is always accurate. DATA The combination of our hardware and application software PRESENTATION (WorkBench PC for DOS or Windows or QuickLog PC) enables both the display of data on the screen, and the logging of data to disk for later analysis. Features and Configurations Chapter 1 Introduction 1 – 2 INTRODUCTION Features and Configurations ANALOG OUTPUT The WB-AVO-12-2 has two output channels, while the WB-AVO- CHANNELS 12-8 allows for up to eight analog outputs. RESOLUTION The WB-AVO is capable of attaining 12-bit resolution (that is, .024% of signal). DATA ACQUISITION The WB-AVO is capable of attaining a data acquisition speed of SPEED 130 kHz, depending on the software being used. The maximum data acquisition rate supported by our software for the WB-AVO is 1 kHz. ACCURACY We guarantee the factory calibration of the boards 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.) DIGITAL I/O The WB-AVO features 8 digital input/output channels that the user can configure individually to be input or output. TERMINAL An available accessory for the WB-AVO is the WB-T31 general PANEL purpose terminal panel, which includes terminals for eight analog outputs and eight digital I/Os. FOR MORE For more information about the capabilities of your data acquisi- INFORMATION tion board, please see the “Product Specifications” in this chapter. For instructions on controlling the board with our interface soft- ware (such as WorkBench PC for DOS or Windows or QuickLog PC), refer to that particular software manual. To learn more about data acquisition and process control in gen- eral, and how to use the Analog Connection systems together to accomplish everyday tasks, consult our Applications manual. And, last but not least, if you’re creating your own program to address the board for a custom purpose, please see the Analog Connection Development System manual. SYSTEM REQUIREMENTS Before installing the board, make sure the computer system fulfills these minimum requirements: WB-AVO Operator’s Manual 1 – 3 WB-AVO OWNER’S MANUAL System Requirements Hardware – · IBM PC XT, AT, (or higher), or -compatible, with at least 640k system RAM and full-size slot for WB- AVO-8 or half-size slot for WB-AVO-2 · Floppy disk drive and a hard drive. Software Environment – · DOS 3.0 (or higher, depending on the application software), · Application software (WorkBench PC for DOS or Windows, QuickLog PC, the Analog Connection Development Sys- tem, or other compatible proprietary software; please see your software manual for directions for using it with the WB-AVO). Chapter 1 Introduction 1 – 4 TECHNICAL NOTES Overview Chapter 2: Installing the WB-AVO Getting your WB-AVO data acquisition and process control board up and running is a straightforward process; you only need to · Verify the board’s switch settings that control board identity and system addressing of OMEGA products, · Physically insert the board into a slot of the personal computer, · Set the voltage/current switches to suit the measurement you are making, · Connect a terminal panel to the board, and · Load and start up the software to be used for the project. As the scope of this manual focuses on the WB-AVO board, this chapter dis- cusses the 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-AVO, 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 DOS or Windows, 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-AVO 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 soft- ware engineers to design and develop their own programs to exploit the WB-AVO’s 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. Troubleshooting – If you have any difficulty getting your board to work, refer to the “Troubleshooting” section in Chapter 3. WB-AVO Operator’s Manual 3 – 1 WB-AVO OPERATOR’S MANUAL Verifying Switch Settings Verifying WB-AVO Switch Settings SINGLE BOARD When you purchase a data acquisition board new from our com- pany, the product’s switch settings already are correct to operate a single board with our software (WorkBench PC for DOS or Win- dows, QuickLog PC, the Analog Connection Development Sys- tem, 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” sec- tion on page 2 – 4 in this chapter, and begin to follow the steps there. MULTIPLE If you are using more than one board at a time, set the individual BOARDS boards’ Board Number Switches first (refer to “Setting the Board Number Switches” on page 2 – 8), 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). PREVIOUSLY If, on the other hand, your board has been in use previously in IN USE another computer, or if your company uses its own proprietary software, the present switch positions might differ from the fac- tory settings.
