DIGITAL INPUT/OUTPUT CARD

IOD-144

USER MANUAL

OPTION SELECTION

Refer to the illustrated setup programs on the diskette provided with the card when reading this section of the manual. Also, refer to the OPTION SELECTION MAP on the following page.

Base address selection is covered both by the diskette and in the next section of this manual.

Interrupts are accepted on the I/O connector, pin 9 (port C3). The interrupt signal is positive true. Interrupts are unconditionally enabled if the IEN jumper is installed, or enabled by program if the INP jumper is installed and I/O connector pin 1 (port C) is low. Interrupts are disabled if (a) neither the IEN or INP jumper is installed, or (b) if the INP jumper is installed but I/O connector pin 1 (port C7) is held high. User interrupts are directed to interrupts #2 through #7, #10 through #12, #14 and #15 by jumpers installed at locations labeled IRQ2 through IRQ15.

The foregoing are the only manual setups necessary to use the IOD-144. Input/Output selection is done, via software, by writing to the PPI 8255-5 Control Registers as described in the PROGRAMMING section of this manual.

IOD-144 provides a means to enable/disable the tristate I/O buffers under program control. If the BEN/TST jumper on the card is installed in the BEN position, the I/O buffers are permanently enabled. However, if the jumper is placed in the TST position, enable/disable of the buffers is possible under software control via the Control Register as described in the Software Programming section of this manual.
