By linking together the functionality of several pods, complex and sophisticated tasks can be performed. Four major application areas are covered on the previous page. Here are a few more. VIPS 10 applications In addition to operation as a data logger, the VIPS 10 has many other applications including: Multi-channel DSO VIPS 30/40/50 applications The VIPS 30, 40 and 50 pods provide multi-channel digital inputs and outputs. Typical applications include: Relay control and monitoring The high current open-collector outputs of the VIPS 40 can be used as relay drivers for power control. Logic Analysis The VIPS 30 and VIPS 50 provide 8-channel logic inputs which can be displayed as a timing diagram or as a state listing. The VIPS 10 pod can be used as a digital storage oscilloscope at speeds up to 10kS/s. Unlike a conventional DSO, resolution is 12 bits and up to 8 channels can be recorded and displayed simultaneously. Digital chart recorder At lower speeds, the graph mode can be used to provide a virtual chart recorder. Sample periods can be selected between 1ms and 10 hours.

VIPS 20 POD Self-contained temperature monitor No. of channels: Resolution: Settling Time: Output Range: The VIPS 10 incorporates a temperature sensor within the pod which o generates a voltage of 10mV per C. By connecting this output to an input channel, temperature can be displayed and logged. VIPS 20 applications The VIPS 20 provides 12-bit precision analogue outputs (up to 4 channels) from DC to kHz. As well as waveform generation, applications include: Internal Reference: Temp. Coefficient: Relative Accuracy: External Ref. Range: Automated calibration source The high resolution and accuracy of the VIPS 20 makes it suitable as a calibration source for a variety of test equipment. 8 single ended or 4 differential channels or a mixture of both. 12 bits. 10µs. 20µs per channel (computer dependent). 0 to 4.096V (Unipolar), ±2.047V (Bipolar). 4.096V ±3mV (Trimmed). Automated controls VIPS digital output modules can be linked to Alarm points on the VIPS 10 or VIPS T100 modules. Thus automated responses can be generated allowing, for example, a process temperature to be maintained. VIPS 60 applications The VIPS 60 provides eight independent analogue switches that can be used to link analogue (or digital) signal points together. These switches allow multiplexers and routers to be configured. The VIPS 60 can be controlled automatically from the alarm settings of a VIPS 10 or VIPS T100. Thus, for instance, different motor drive signals generated from a VIPS 20 could be selected automatically in response to a transducer measurement. As with all VIPS modules, DLL drivers are available which enables the module to be controlled from a user defined program. 4. 12 bits. 25µs to ± ½LSB. ±2.047V (bipolar), 0V to 2.047V (unipolar) or 0V to 4.095V (unipolar). 2.048V (typ) (2.017min to 2.079max). 50ppm/°C. ±1 LSB. -3V to +3V (can use as MDAC input).

The main VIPS program includes control windows for up to four pods and display modes of DSO (digital storage oscilloscope), Graph (chart recorder), Bars (bar graph display in real time), Meters (digital displays scaled to engineering units) and List (tabulated results or events). Data can be logged to disk using the LOG function which creates text files for printing or viewing. Files of raw data can also be stored. Waveform generation functions are included for use with the VIPS20. VIPS-DDE is provided for use with other Windows applications that support DDE. DLL hardware drivers are provided for each VIPS pod/module. VIPS X-BOX This expansion box is required when more than one VIPS module needs connecting to a single parallel port or when a printer is also required to be connected to the same parallel port. Any VIPS module can be connected to any position. The printer can be used whilst the VIPS modules are connected, but they will have to be disabled whilst a document is being printed. VIPS CONNECTION BOARD Connections to a VIPS pod are normally made via the 25-pin D-connector. Where this is not convenient, the VIPS connection board provides an alternative. It provides screw terminal connection points for all 25 pins. The terminals can be unplugged from the board when required.

The VIPS pod is connected to the PC parallel port and is powered from it. No power source is required. Any type of PC can be used including lap-tops. Unlike competitive units, multiple VIPS pods can be operated and controlled simultaneously using one parallel port. The VIPS software operates under Windows (3.1, 95 or 98) and provides comprehensive display and control for between one and four VIPS pods. It can be used simultaneously with other Windows applications such as spreadsheets, maths packages etc. Multiple viewing modes Data can be viewed in many different ways: as a virtual 'scope or logic analyser, as a graph, as a data list, as annunciators, as digital meters, or as vertical bars. Data channels can be given labels and analogue values can be scaled to user-defined engineering units using Ax+B formulae on a per-channel basis. The whole configuration can be saved to disk so that a variety of configurations can be called up as required. Data logging to disk Single pod simplicity Any single VIPS pod can be operated directly by simply plugging it into the PC parallel port. Each pod is supplied with full software, nothing else is needed. Multi-pod sophistication VIPS software enables up to four VIPS pods to be controlled and monitored simultaneously. The X-Box expansion module enables multiple pods to be connected. It links to the parallel port via a cable (supplied) and gives a docking connection for up to four VIPS pods (in any combination) as well as providing a printer feed-through port.

A complete system operating from the parallel port of your PC An expandable multi-channel Data Logger A multi-channel waveform generator A VIPS 10 pod operating under VIPS software can act as a high speed, multi-channel 12-bit data logger. It has 8 signal inputs which can be configured as 8 single ended measurement inputs or 4 differential inputs (or a mixture of the two). If more channels are required, the system can be expanded by adding up to three further VIPS 10 pods thus providing up to 32 inputs. The VIPS 20 incorporates four high speed 12-bit DACs perfectly suited to waveform generation. VIPS software includes easy-to-use function generator controls which allow the generation of sine, square, triangle and ramp waveforms as well as dc levels and random noise. The software provides precise control of frequency, level and dc offset as well as waveshape - all on a per-channel basis. Alternatively arbitrary waveforms can be created and replayed from disk based files. Waveforms can be captured from a VIPS 10, or imported from Exel spreadsheets or from mathematical programs and waveform creation and editing programs such as WaveCad 1 or Waveform Manager 2. Data can be acquired at rates between one sample per 10 hours and 10,000 samples per second. The data can be displayed in any of five formats (subject to an appropriate acquisition rate): Listing, Bar Graph, Digital Meters, Chart, DSO. Logger results can be written to a file or sent to a printer. DDE links can be used to import to a spreadsheet or other application in real time. DDE support High resolution temperature measurement A full Measurement and Control system The VIPS T100 is a complete 16-bit resolution measurement module for thermocouples. Six miniature thermocouple connectors are provided, each suitable for types B, E, J, K, N, R, S or T. Thermocouple types can be mixed on the same T100. Resolution for all types is 0.1oC, and temperature can be displayed in oC, oK or oF. VIPS can provide much more than just data logging. It can combine analogue and digital inputs with analogue and digital outputs to form a complete measurement and control system. VIPS software enables up to four pods to be monitored and controlled simultaneously. Each analogue input can have two user defined alarm levels with visual indication of status provided on screen. The alarms can be linked to a digital output pod to provide control functions based upon analogue measurements. Digital inputs can be displayed as lamp-style annunciators, as an event list, or as an event chart (graph mode). More experienced users, particularly those with programming skills, can make use of DDE links or DLL drivers to take direct control of VIPS hardware and create dedicated measurement and control functions. VIPS T100 multi-channel temperature measurement module with 16-bit resolution and six miniature thermocouple connectors. DLL drivers VIPS X-Box Expansion Module Full Windows software supplied with every pod multiple pods running simultaneously, powered from the PC VIPS Control Software 1 WaveCad is a Windows based programme for generating and editing arbitrary waveforms using graphical tools and mathematical equations. 2 Waveform Manager is a Windows 95 based programme which provides translations between many different data formats used by DSOs and waveform generators. Each VIPS unit is supplied complete with the VIPS control software which operates under Windows 3.1, Windows95 or 98. The main VIPS screen is divided into several working areas. A wide variety of display modes can be selected within the large window. These include DSO, Bars, Graph, Meters, Annunciators and Listing. The four upper windows can be allocated to individual VIPS pods. The channels can be displayed simultaneously using colour coding to aid clarity. Channels can be individually disabled. The large window provides a full-size control and display area for one of the pods and can be switched between them by a single mouse click. Analogue displays can be scaled and shifted in software on a per-channel basis. Channels can be named and measurements shown in engineering units. Data can be logged to disk at timed intervals and displayed, printed, or imported into spreadsheets. Two alarms can be set for each analogue input channel. The alarms can be linked to a VIPS digital output module or analogue switch module to provide automatic control functions. Each input can alternatively be used for voltage measurement with a sensitivity down to 1µV. In common with the whole VIPS range, the T100 can be used as part of a multi-module system operating up to four VIPS units simultaneously. Where more thermocouple inputs are required, up to four T100s could be used together giving 24 temperature measurement channels. Unlike the other VIPS modules, the T100 is housed in a compact metal case and is connected to the computer (or to the VIPS X-Box) via a screened cable (supplied). VIPS software provides the full range of display modes and each channel can be allocated an individual name.

VIPS T100 multi-channel temperature measurement module with 16-bit resolution and six miniature thermocouple connectors. DLL drivers VIPS X-Box Expansion Module Full Windows software supplied with every pod multiple pods running simultaneously, powered from the PC VIPS Control Software 1 WaveCad is a Windows based programme for generating and editing arbitrary waveforms using graphical tools and mathematical equations. 2 Waveform Manager is a Windows 95 based programme which provides translations between many different data formats used by DSOs and waveform generators. Each VIPS unit is supplied complete with the VIPS control software which operates under Windows 3.1, Windows95 or 98. The main VIPS screen is divided into several working areas. A wide variety of display modes can be selected within the large window. These include DSO, Bars, Graph, Meters, Annunciators and Listing. The four upper windows can be allocated to individual VIPS pods. The channels can be displayed simultaneously using colour coding to aid clarity. Channels can be individually disabled. The large window provides a full-size control and display area for one of the pods and can be switched between them by a single mouse click. Analogue displays can be scaled and shifted in software on a per-channel basis. Channels can be named and measurements shown in engineering units. Data can be logged to disk at timed intervals and displayed, printed, or imported into spreadsheets. Two alarms can be set for each analogue input channel. The alarms can be linked to a VIPS digital output module or analogue switch module to provide automatic control functions. Each input can alternatively be used for voltage measurement with a sensitivity down to 1µV. In common with the whole VIPS range, the T100 can be used as part of a multi-module system operating up to four VIPS units simultaneously. Where more thermocouple inputs are required, up to four T100s could be used together giving 24 temperature measurement channels. Unlike the other VIPS modules, the T100 is housed in a compact metal case and is connected to the computer (or to the VIPS X-Box) via a screened cable (supplied). VIPS software provides the full range of display modes and each channel can be allocated an individual name.
