Measurement Computing CIO-DAC08/16 - Manual (Page 6)

3.0 HARDWARE INSTALLATION
The CIO-DAC16/16 and DAC08/16 each has one bank of range jumpers, a single
unipolar/bipolar jumper, one base address switch and a simultaneous update jumper
which must be set before installing the board in your computer. The InstaCal program
included with both boards shows how these switches are set. Run this program before
you open your computer.
We recommend you perform the software installation described in
sections below prior to installing the board in your computer. The
InstaCal
TM program provided will show you how to properly set the
switches and jumpers on the board prior to physically installing the
board in your computer.
The CIO-DAC16/16 is setup at the factory with:
BASE ADDRESS 300h (768 decimal)
SIMULTANEOUS UPDATE In the UPDATE position. Single channel update.
ANALOG OUTPUT ±5V
UNI / BIP JUMPER BIP
3.1 BASE ADDRESS
Unless there is already a board in your system which uses address 300h (768 decimal)
leave the switches as they are set at
the factory. The base address switch
for the CIO-DAC16/16 is shown
here, set to 300 hex. The
CIO-DAC08/16 has one additional
switch on the base address switch
bank (A4 with a weight of 10 hex).
Figure 3-1. Base Address Switches (Set to 300h)
The address switches may be set for a base address in the range of 000-3E0 (3F0 for
the DAC08) so it should not be hard to find a free address area. Once again, if you
are not using IBM prototyping cards or some other board which occupies these
addresses, then 300-31Fh are free to use. Addresses not specifically listed, such as
390-39F, are free.
Refer to table 3-1 for PC I/O address usage.
