-Driver: adq12b
-Description: driver for MicroAxial ADQ12-B data acquisition and control card
-Devices: [MicroAxial] ADQ12-B (adq12b)
-Author: jeremy theler <thelerg@ib.cnea.gov.ar>
-Updated: Thu, 21 Feb 2008 02:56:27 -0300
-Status: works
-
-Driver for the acquisition card ADQ12-B (without any add-on).
-
- - Analog input is subdevice 0 (16 channels single-ended or 8 differential)
- - Digital input is subdevice 1 (5 channels)
- - Digital output is subdevice 1 (8 channels)
- - The PACER is not supported in this version
-
-If you do not specify any options, they will default to
-
- # comedi_config /dev/comedi0 adq12b 0x300,0,0
-
- option 1: I/O base address. The following table is provided as a help
- of the hardware jumpers.
-
- address jumper JADR
- 0x300 1 (factory default)
- 0x320 2
- 0x340 3
- 0x360 4
- 0x380 5
- 0x3A0 6
-
- option 2: unipolar/bipolar ADC selection: 0 -> bipolar, 1 -> unipolar
