2.7.10 Cascaded 32-bit Counter
You can also cascade counter 0 and counter 1 together as one 32-bit
counter/timer, and it’s
configured by control bit - CTR32Set.
Note: UNO-3072Lprovides built-in examples to show how to deliver
counter functionality. Refer to console mode examples in C:\Program
Files\Advantech\UNO\UNO_IsaDIO\Examples\Console. (Please install
DI/O driver from the UNO CD to use these examples)
2.8 Power Input
UNO-3072Lcomes with a Phoenix connector that carries 16~36 VDC
external power input,
and features reversed wiring protection. Therefore, it
will not cause any damage to the system
by reversed wiring of ground line
and
power line. (Please refer to Figure 2.12 for location of power input)
The UNO-3072Lsupports two
individual power inputs (P1/P2). ( Please
refer to Appendix
A.7 for wiring of P1 and P2)
