2.2 HARDWARE

2.2.1 Base I/O Address

The CIO-DAS-TEMP may be set to operate at any one of a range of base addresses. T he

CIO-DAS-TEMP uses eight, 8-bit addresses, so the base addresses available are in steps of eig ht. For

example, 300h, 308h, 310h and so on. Table 2-1 of occupied PC addresses below should be

supplemented by information you provide about the addresses used by any other boards or devices

installed in your computer. After all occupied addresses are known, choose an available block of eight

I/O addresses for your CIO-DAS-TEMP. Make sure it is on a 3-bit (8-address) boundary.

Address 300H Shown Below

The Base Address is set by a switch on the

CIO-DAS-TEMP labeled ADDRESS. The

CIO-DAS-TEMP uses eight, 8 bit addresses.

The board is set at the factory for address 300h (

768 decimal) as shown here. It is a com mon

address for I/O boards and may already be in use

in your computer. Verify that it, or the address

you choose is available.
