- eXtended Digital I/O functionality including pulse-width modulation, quadrature and edge counting, and pulse timing with IRQ/DRQ support.
- TS-DIO64 Digital I/O Board, which is a 8-bit PC/104 (standard format) peripheral board that provides 64 digital I/O points (32 inputs plus 32 outputs). Up to 4 TS-DIO64 boards may be installed into a single system, enabling up to 256 DIO points (128 inputs plus 128 outputs). The TS-DIO64 DIO functions are compatible with any PC/104 SBC including all the Technologic Systems ARM and X86 products.
