The IP-UD-E digital I/O IndustryPack provides 24 flexible input/output signal lines with TTL-level inputs and outputs. Outputs will sink up to 4 mA of continuous load current. Inputs will handle TTL levels. Each line may be dynamically and individually configured for either input or output, providing maximum flexibility. Inputs and outputs may be double buffered, making the IndustryPack compatible with simulation systems requiring many inputs and outputs to be latched simultaneously.
Writing a one to any line turns off the output driver, allowing a passive
pull up resistor to set the line to a logic high. Writing a zero to any line
turns on the driver, driving the line to a logic low. For input use, a one is
written to the corresponding line—this is the power up default. For output
use, the binary value desired is written to the corresponding line.
Input and output lines may double buffered by providing an external
clock. A bit in the Control Register selects the polarity of this clock,
allowing inputs and outputs to be latched on either the rising or falling
clock edge. Any CMOS/TTL compatible clock source may be used.
The IndustryPack can function in a Master/Slave Mode for synchronizing
multiple IndustryPacks. In this mode, the Master IndustryPack redrives the
external clock source out I/O line 23. This line becomes the Master
Clock, which should be wired to I/O line 24 on the Master and all Slave
IndustryPacks.
Reset turns off the open collector output driver and sets disables double
buffering for a consistent software interface.
Windows NT drivers are available.
