Page 6: Introduction
When a large scale system is required, multiple boards can be added from the 200 Series without conflict. For analog input systems, the capacity of the PC mounted hardware can be extended by external expansion panels to provide a convenient to use system with low cost per channel and maintained high performance. -
Page 7: General Description
General Description The PCI224/234 range of boards provide multi-channel data acquisition functions for any IBM PC or compatible computer that supports PCI bus version 2.1 All models are supported by Windows 95 & NT drivers. These drivers allow the advanced features of the cards to be fully utilised by the application software. -
Page 8: The Software
PCI234 BLOCK SCHEMATIC 1.4.3 The Software The PCI224/234 is supplied with the SOFTMAN CD-ROM Part No 869 865 59, this contains all the software for the card, and is documented in the Amplicon ADIO manual elsewhere on the CD ROM. PCI224/234... -
Page 9: What The Package Contains
When removed from the bag, inspect the board for any obvious signs of damage and notify Amplicon if such damage is apparent. Do not plug a damaged board into the host computer. Keep the protective bag for possible future use in transporting the board. -
Page 10: Contacting Amplicon Liveline Limited For Support Or Service
Before returning the goods, please request an individual RMA number by contacting Amplicon Customer Services by telephone or fax on the above numbers. Give the reason for the return and, if the goods are still under warranty, the original invoice number and date. -
Page 11: Getting Started
BEFORE INSTALLING OR REMOVING ANY EXPANSION BOARD. OBSERVE HANDLING PRECAUTIONS NOTED IN SECTION 1.4. REPAIR OF DAMAGE CAUSED BY MIS-HANDLING IS NOT COVERED UNDER THE AMPLICON WARRANTY. DO NOT MAKE ANY MODIFICATIONS OTHER THAN SWITCH CHANGES TO A BOARD THAT IS ON EVALUATION Please refer to the manufacturer's hardware manual supplied with the PC for instructions on how to remove the cover and install devices into an input/output slot. -
Page 12: Windows Nt Installation
Windows will now proceed to copy the driver software from the CD. If Windows asks for the ‘Amplicon DIO Drivers Disk’ to be inserted, ensure the SOFTMAN CD is in the drive, click ‘OK’, click ‘Browse’, browse to the top-level directory of the SOFTMAN CD (which contains the file Windows is trying to find) and click ‘OK’. -
Page 13: Card Configuration
After rebooting the PC, the PCI224 or PCI234 will be detected by the installed driver and configured automatically. The Amplicon DIO control panel applet can be used to verify that the board has been detected. This will also show the base address and IRQ settings for the board. -

Page 16: Making The Connections
MAKING THE CONNECTIONS This chapter describes the signal and control connections that the user must make between the PCI224/234 and any external devices. These input/output connections are made through the D-type connector protruding from the PC adapter slot corresponding to the chosen board position. The metal shell connected to the local PC chassis ground. -

Page 23: Using The Pci224/234
This chapter describes the various hardware operations associated with implementing the user’s application. Programming operations are discussed in the Amplicon ADIO driver manual elsewhere on the softman CD ROM. Details of the registers and software are given in chapters 5 and 6 respectively. -
Page 24: Pci224 Output Voltage Range
4.1.2 PCI224 Output Voltage Range The output ranges of the DACs can be selected by varying the reference voltage supplied to the DACs. The output voltage range is established by the gain setting of the analog amplifiers preceding the DAC. Selection of internal reference voltage is made in software by writing to the DACMOD register. -
Page 25: Pci234 Output Voltage Range
4.2.1 PCI234 Output Voltage Range The output ranges of the DACs can be selected by varying the reference voltage supplied to the DACs. When using the internal voltage reference the output voltage can be varied between ±10 volts or ±5 volts. Alternatively the user may use an external reference voltage. The Factory default output voltage range is ±10V bipolar using the internal reference. -
Page 26: Continuous Fifo Mode' Interrupt Controlled D/A Conversion
4.3.2 ‘Continuous FIFO Mode’ Interrupt Controlled D/A Conversion In this mode upto sixteen channels of analog output, can be updated continuously. Timing is controlled by a hardware generated clock thereby making conversion rates deterministic. The clock may come from one of the 82C54 timer/counters. The driver software will default to use Counter 1 and will program it as a square wave generator at the required sampling interval. -
Page 27: Channelling
4.3.4 Channelling Each time a conversion is initiated In ‘Interrupt Controlled D/A Conversion’ mode the card automatically outputs the sample to the next channel in ascending number order from the channels enabled in the DAC channel enable register. In this way the card automatically cycles all analog outputs sequentially outputting from the FIFO if it is enabled. -
