Manual PCIe-DIO-120/96/72

Chapter 3: Hardware Details
Refer to the illustrated setup program installed with the software package when reading
this section of the manual. Also, refer to Figure 3-1, Option Selection Map.
External interrupts are accepted on pin 9 (Bit C3) of each I/O connector when enabled
by software. The interrupt signal should be a rising edge and is latched.
As pointed out in Chapter 1 of this manual, outputs of the I/O buffers may be either
pulled-up to VCCIO or pulled down to ground. You can configure these resistors per
port.
VCCIO signaling levels are globally configured via jumper selection. Refer to the
specifications chapter for signal levels for each possible selection.
The foregoing are the only manual setups necessary to use these cards. Input/Output
selection is done via software, by writing to the GROUP Control Registers as described
in the Programming section of this manual.
