22 Description: Amplicon PCI263
23 Author: Ian Abbott <abbotti@mev.co.uk>
24 Devices: [Amplicon] PCI263 (amplc_pci263)
25 Updated: Fri, 12 Apr 2013 15:19:36 +0100
28 Configuration options: not applicable, uses PCI auto config
30 The board appears as one subdevice, with 16 digital outputs, each
31 connected to a reed-relay. Relay contacts are closed when output is 1.
32 The state of the outputs can be read.
