Functions and Operating Procedures
Functional Overview
The AD12-16(PCI) or AD12-64(PCI) board consists of the
following four independent function blocks:
(1) Analog input function
(2) Digital input function
(3) Digital output function
(4) Interrupt function
Description
Analog Input Function
By outputting a sampling start command, the board converts an
analog input signal into 12 bit digital data under specified sampling
conditions, at a maximum rate of 10 microsecond/channel.
The conversion operation is roughly divided into the following two:
Software mode
:
Sampling operation is performed once
for a channel specified by sampling
start command.
Clock mode
:
Sampling operation is performed
periodically for a specified channel, in
sync with a sampling clock.
A sampling clock can be used either derived from a dedicated clock
signal on board or an external clock signal.
Channels to be sampled are specified in the following two modes:
Single-channel mode
:
A specified channel is sampled by a
single sampling operation.
Multi-channel mode
:
Specified two or more channels are
sampled by a single sampling operation.
A/D conversion is performed by combining the above clock and
sampling modes.
