CHAPTER 1 INTRODUCTION
1.1 GENERAL DESCRIPTION
The AR-B3001 is a low cost, high accuracy, low noise,
low drift A/D interface boards for the IBM PC/XT/AT and
their compatibles. It is half-length boards that install
internally in an expansion slot of an IBM Personal
Computer to turn the computer into an inexpensive, high-
precisioninstrumentfortemperature,humidity,pressure,
flow and level etc.. The AR-B3001 is constructed with a
12-bit (plus polarity bit) dual-slop integrating A/D
converter. It can be operated with 16 single-ended or 8
differential analog inputs. The analog input range of AR-
B3001 is -5V to +5V.
A complete software utility containing demo programs,
Assembly, Basica, and C drivers are furnished with the
board to minimize user's effort on application software
development. All the driver routines are provided with
source programs and can be modified to suit your
applications.
Block diagram of AR-B3001 is shown in figure 1-1.

CHAPTER 2 INSTALLATION
This chapter provides instructions for installing the AR-
B3001 in an IBM PC/XT/AT and compatibles.
2.1 SWITCHE, JUMPER AND CONNECTOR
There is one DIP switch and one jumper on the AR-
B3001. This section describes functional use of the
switch and jumper. It also provides a description of the
input connector. Figure 2-1 shows the location of each
switch, jumper, and connector for AR-B3001. Table 2-1
list the functions of jumper, switch, variable resistors and
connector shown in Figure 2-1.

2.1.1 Base Address Settings
There is one DIP switch located on the AR-B3001 card.
It is used to select the base port address of the AR-
B3001. The operation of AR-B3001 is controlled through
the I/O ports. Four consecutive I/O ports are used by AR-
B3001. The base address of these I/O ports is selected
by using base address switch DIP SW. The AR-B3001 is
factory-configured for a base address of 3e0 Hex. If this
base address is already occupied, you will need to
change the base address switch setting. It is essential
that each peripheral device, such as an AR-B3001, be
assigned a unique base address within the range of 200
to 3fc Hex and that the address is on a 4-byte boundary.
Figure 2-2 shows the base address switch.

Use the following table to select an AR-B3001 base port
address.

Address = 512*A9 + 256*A8 + 128*A7 + 64*A6 + 32*A5
+ 16*A4 + 8*A3 + 4*A2 (Dec)
A9....A2 = 0 If switch is ON.
A9....A2 = 1 If switch is OFF.
Note: Setting the switch to the "ON" position indicates a
logical "0" and setting the switch to the "OFF"
position indicates a logical "1".

2.1.2 Channel Configuration Jumper
The JP1 is used to select whether 16 single-ended or 8
differential analog input channels are to be used. To
select eight differential input channels, move the jumpers
to the right side. Likewise, to select 16 single-ended
analog input channels, move the jumpers to the left side
as shows in Figure 2-3.
