Below is a block diagram of the counter timer used on the KPCI-3108 or KPCI-
The 82C54 chip provides three 16bit counters: CT0, CT1 and CT2. DriverLINX
assigns the following logical channels to these counters:
Channel 0: 32bit cascade of CT1 and CT2
Channel 1: CT0
Channel 2: CT1
Channel 3: CT2
For C/T functions that use inputs, such as event counting, simply connect to the
correct IPx pin number corresponding to the selected channel.
For C/T output functions, such as Square Wave Generation, the OPx must be
configured in the DriverLINX Configuration Panel to serve as CT outputs.
Access this from the `Special Button' on the Device tab for your assigned device
number (see below).
In each case, the IPx or OPx terminals are no longer available for their default
role as digital inputs or outputs if in use for C/T functions.
