Specifications

Comedi
118 / 148
Tested with lab-pc-1200. For the older Lab-PC+, not all input ranges
and analog references will work, the available ranges/arefs will
depend on how you have configured the jumpers on your board
(see your owner’s manual).
Kernel-level ISA plug-and-play support for the lab-pc-1200
boards has not
yet been added to the driver, mainly due to the fact that
I don’t know the device id numbers. If you have one
of these boards,
please file a bug report at https://bugs.comedi.org/
so I can get the necessary information from you.
The 1200 series boards have onboard calibration dacs for correcting
analog input/output offsets and gains. The proper settings for these
caldacs are stored on the board’s eeprom. To read the caldac values
from the eeprom and store them into a file that can be then be used by
comedilib, use the comedi_calibrate program.
Configuration options - ISA boards:
[0] - I/O port base address
[1] - IRQ (optional, required for timed or externally triggered conversions)
[2] - DMA channel (optional)
Configuration options - PCI boards:
[0] - bus (optional)
[1] - slot (optional)
The Lab-pc+ has quirky chanlist requirements
when scanning multiple channels. Multiple channel scan
sequence must start at highest channel, then decrement down to
channel 0. The rest of the cards can scan down like lab-pc+ or scan
up from channel zero. Chanlists consisting of all one channel
are also legal, and allow you to pace conversions in bursts.

Thanks go to Fredrik Lingvall for much testing and perseverance in
helping to debug daqcard-1200 support.
