Page 7: Enhanced Features
16-bit counter/timers only. 1.4.1 Enhanced Features The PCI230/260 support all relevant features of the earlier ISA bus products, i.e. the PC30AT and the PC26AT. In addition the PCI230/260 have many advanced features. The PCI230 & PCI260 both have a 4096-sample FIFO for buffering input samples from the ADC. The cards can be set up to store samples in the FIFO autonomously until the FIFO is full at which time the card will issue an interrupt to the PC. -
Page 8: The Software
PCI260 BLOCK SCHEMATIC 1.4.3 The Software The PCI230/260 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. -
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
If the PCI230/260 requires repair then please return the goods enclosing a repair order detailing the nature of the fault. If the PCI230/260 is still under warranty, there will be no repair charge unless any damage is a consequence of improper use. -
Page 11: Getting Started
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. The PCI230/260 may be installed in any available position in the machine provided that there is no restriction specified for that location by the computer manufacturer. -

PCI230/260. This will extract and run file ADIO32.EXE on the SOFTMAN CD. Follow the instructions to install the samples onto your PC. 2. After rebooting the PC, the PCI230 or PCI260 will be detected by the installed driver and configured automatically. -
Page 14: Card Configuration
IRQ sharing The interrupt request line, IRQ 3-5, IRQ7, IRQ10-12 or IRQ15, signals the host PC (Permanent Master) that the PCI230/260 adaptor requires service. The host PC acknowledges the interrupt and performs the required action using the appropriate interrupt service routine. -

Page 19: Signal Termination Assemblies
Connections to the PCI230/260 I/O lines are made via D-Type connectors on the rear panel. The on-board connectors are 50 way female for the PCI230 SK1 and 25 way male for the PCI260 PL1. The mating connectors are available as accessories. Provision is made for securing by screw jacks. -
Page 20: Pci230 Screw Termination Assembly
3.2.1 PCI230 Screw Termination Assembly User connections for the PCI230 can be made by wiring directly to a 50 way D type mating connector (male). Alternatively for much easier connection to plant or experimental signal wiring, a screw terminal assembly and interconnecting cable of 1 metre length can be supplied as optional accessories. -
Page 21: Analog Inputs
It is important that no input voltage is allowed to exceed the limits of the multiplexer, i.e. signal voltage must not exceed ±15 volts when the power to the PCI230/260 is on or ± 2 volts when the power is off. -

PCI260) is therefore common to analog input and output channels. Digital I/O lines are referred to a second ground pin at (SK1/18 on the PCI230 and PL1/2 On the PCI260). Connections for single-ended analog input and output for the PCI230 are shown diagrammatically below. -
Page 24: Figure 3.7 Input Voltage Ranges
Use separate ground wires for analog input, analog output, digital I/O and power lines. Keep the common ground impedance to a minimum by making the ground point as close as possible to the PCI230/260 I/O connector or terminal block, and/or use a heavier gauge wire for the ground connection. -

Page 27: Using The Pci230/260
The FIFO allows many samples to be stored locally preventing samples from being overwritten before the host can respond to the PCI230 interrupt. This feature greatly extends the maximum sample rate of the system for multi-tasking operating systems. -
Page 28: Interrupt Controlled Sampling
In this way the card automatically cycles all analog inputs building up results sequentially in the FIFO if it is enabled. Channels can only be enabled as pairs to simplify the digital design when forming differential inputs Page 23 PCI230/260... -

Page 30: Analog Outputs (Pci230 Only)
32752 Analog Outputs (PCI230 Only) The PCI230 provides two channels of analog output, from individual digital to analog converters. The two channels are labelled DAC 1 and DAC 2 on the I/O connector. The output ranges of the DACs can be selected to be unipolar (0 to +10 volts) or bipolar (±10 volts). Selection is made in software by writing to the DACCON register. -

Page 33: Structure And Assignments Of The Registers
Register Groups There are two register groups occupied by the PCI230/260. I/O Space 1 is eight bits wide I/O Space 2 is sixteen bits wide. Sixteen bit data transfers are employed where appropriate, and high speed is achieved by the use of the sixteen bit transfers to read blocks of data from the FIFO, 4096 12 bit words to a block. -
