26 Description: 32/64-Channel Isolated Digital I/O Boards
27 Devices: (ADLink) PCI-7230 [adl_pci7230] - 16 input / 16 output
28 (ADLink) PCI-7233 [adl_pci7233] - 32 input
29 (ADLink) PCI-7234 [adl_pci7234] - 32 output
30 (ADLink) PCI-7432 [adl_pci7432] - 32 input / 32 output
31 (ADLink) PCI-7433 [adl_pci7433] - 64 input

37 The PCI-7230, PCI-7432 and PCI-7433 boards also support external
38 interrupt signals on digital input channels 0 and 1. The PCI-7233
39 has dual-interrupt sources for change-of-state (COS) on any 16
40 digital input channels of LSB and for COS on any 16 digital input
41 lines of MSB. Interrupts are not currently supported by this
44 Configuration Options: not applicable, uses comedi PCI auto config
47 #include <linux/module.h>
