Introducing the PCI-CTR05
The PCI-CTR05 is a high-performance, low-cost counter/timer board for PCI bus-compatible computers.
The PCI-CTR05 is based on the 9513 counter/timer device. The PCI-CTR05 has one 9513 counter/timer device.
The 9513 device has five independent 16-bit counters (65,536 counts). Each counter has an input source, count
register, load register, hold register, alarm register, output, and gate associated with each counter.
The 9513 is software-programmable for event counting, pulse and frequency measurement, alarm comparisons,
and other input functions. The 9513 can generate frequencies with either complex duty cycles, or with one-shot
and continuous-output modes. You can chain up to five 9513 counters together using software to enable a 32-,
48-, 64-, or 80-bit counter that does not require hardware connections. The gate source and gating functions are
software-selectable.
An eight-bit, high-current digital output port provides logic-level control, and can be used to switch solid state
relays. An eight-bit digital input port can be used to sense contact closures and other TTL level signals. The
PCI-CTR05 also provides access to the PCI bus interrupt assigned to the board.
Depending on the revision of your PCI-CTR05, it may support both 3.3 V and 5 V PCI signaling environments,
or only 5 V PCI signaling environments. Refer to
Installing the hardware
to learn how to determine the PCI
signaling environments your board supports.
