Chapter 1 Introduction
AR-B104D is a PCI-104 board which contains 12 general purposed input
channels with pulse counter alternative function, 12 general purposed output
channels with pulse generator alternative function, SRAM with battery supplied,
hardware timer, and CAN-bus interface.
In order to ease the customer’s operation on AR-B104D, Acrosser provides
device driver, application interface (API), and source code of demo application.
The provided software is available on Windows XP and Linux. The API can be
classified into five catalogs: General usage, SRAM, GPIO, Timer, CANBUS.
The details are described in Chapter 2. All software can be located on the
bundled disc.
There are some limitations on AR-B104D driver:
It can only run on the system with ACPI and APIC enabled.
It has completely tested on Windows XP SP3 with ACPI supported.
Thus, we recommend operating AR-B104D on such environment.
