| 24 | Driver: icp_multi |
| 25 | Description: Inova ICP_MULTI |
| 26 | Author: Anne Smorthit <anne.smorthit@sfwte.ch> |
| 27 | Devices: [Inova] ICP_MULTI (icp_multi) |
| 28 | Status: works |
| 29 | |
| 30 | The driver works for analog input and output and digital input and output. |
| 31 | It does not work with interrupts or with the counters. Currently no support |
| 32 | for DMA. |
| 33 | |
| 34 | It has 16 single-ended or 8 differential Analogue Input channels with 12-bit |
| 35 | resolution. Ranges : 5V, 10V, +/-5V, +/-10V, 0..20mA and 4..20mA. Input |
| 36 | ranges can be individually programmed for each channel. Voltage or current |
| 37 | measurement is selected by jumper. |
| 38 | |
| 39 | There are 4 x 12-bit Analogue Outputs. Ranges : 5V, 10V, +/-5V, +/-10V |
| 40 | |
| 41 | 16 x Digital Inputs, 24V |
| 42 | |
| 43 | 8 x Digital Outputs, 24V, 1A |
| 44 | |
| 45 | 4 x 16-bit counters |
| 46 | |
| 47 | Options: |
| 48 | [0] - PCI bus number - if bus number and slot number are 0, |
| 49 | then driver search for first unused card |
| 50 | [1] - PCI slot number |
