Acces I/O products PCI-DIO-48H Скачать руководство пользователя страница 7

I/O wiring connections are via a 100-pin high-density connector. If an IDC type mating connector is used then
two flat 50 wire ribbon cables can connect these cards to termination panels. Also, this provides compatibility
with A24A, OPTO-22, Gordos, Potter & Brumfield, et al solid-state-module mounting racks. Every second
conductor of the flat cables is grounded to minimize crosstalk between signals in the cables. If needed for
external circuits, +5 VDC power is available at pins 49 and 99. If you use this power, we recommend that you
include an external 1A fast-blow fuse in your circuits in order to avoid possible damage to the host computer or
cable in the event of a malfunction in those external circuits.

These cards occupy sixteen bytes of I/O address space. The base address is selected by the system. An
illustrated setup program is provided on the diskette or CD shipped with your card. Interactive displays show
locations and proper configuration of jumpers to set up the interrupt-enable function. Also, sample programs in
Turbo-C and Turbo-Pascal are presented in the Software section of this manual.
