Programming; I/O Address Map; Table 6-1. Dac-02 Register I/O Address Map - Keithley DAC-02 User Manual

You can operate the DAC-02 by writing I/O commands in programming
languages such as BASIC, QuickBasic, C, and Pascal. This chapter
provides the register-level programming information you need for writing
these I/O commands.

I/O Address Map

The DAC-02 uses eight consecutive addresses in the I/O address space of
the computer. The board's base address (Base Address +0h) determines
where the registers of the board are located in the I/O space. Table 6-1 is a
map of the DAC-02 register I/O addresses.
I/O Address
Base Address +0h
Base Address +1h
Base Address +2h
Base Address +3h
Base addresses +4h to +7h are redundant; they repeat the pattern of the
first four addresses and can be ignored during programming.
