Introduction
AD12-64(PCI), AD12-16(PCI) 1
1. Introduction
Thank you for purchasing our non-insulated type analog input
board. The product is a PCI-compliant analog input board, which
is provided with analog input function for converting analog signals
into digital signals, digital input/output function, and programmable
timer function. This board is used by inserting it in a PCI-bus
expansion slot on a PC main unit or a slot on an I/O expansion unit.
Read this manual carefully for setting up the board and connecting
the board to peripheral devices. For building an application under
Windows 98, Windows 95, or Windows NT environment, use
optionally available support software.
Support software sold separately
API-PAC(W32) Ver. Aug. 1999 or later
The API-PAC(W32) does not necessarily support full functions of
the board. Make sure specifications of the driver software before
purchase.
Features
-Multi-channel analog input capability
64 single-ended analog inputs or 32 differential analog inputs
(AD12-64(PCI)). 16 single-ended analog inputs or 8 differential
analog inputs (AD12-16(PCI)). Single-ended or differential
input is selected by software.
-8-type selectable input ranges
Input ranges are selectable among 8-types including both unipolar
and bipolar inputs. Ranges are selectable for each channel, and
changing ranges is allowed under operation.
-Sampling control
Two types of sampling functions are provided, namely sampling
by software command and periodical sampling in synchronization
with sampling clock. Either a special-purpose clock signal on
board or an external clock signal is selectable as a sampling
clock.
Introduction
AD12-64(PCI), AD12-16(PCI)2
-Digital input/output
The board is capable of four TTL-level digital inputs and four
TTL-level digital outputs.
-Programmable timer function
The board is provided with an independent programmable timer.
The timer allows generating interrupts and outputting count-up
signals at regular intervals. The timer can be monitored on the
basis of status without using interrupt capability.
-External trigger input capability
The board allows generating an interrupt by inputting a TTL-level
digital signal. Also, trigger input can be monitored on the basis
of status without using interrupt capability. Status of input
signals can be monitored directly. This function is independent
of other functions.
-Capability of generating interrupts by multiple causes
The board is capable of monitoring sampling operation,
programmable timer, or external trigger, etc. simultaneously.
-The following optional devices are available for easier connecting
and wiring
Relay terminal box EPD-96 *
96-pin half-pitch connector shield cable (one end)
PCA96PS
96-pin half-pitch connector shield cable (both ends)
PCB96PS
* An optional cable (PCB96PS) is required separately.
