VTC334583 8-ch Counter/Timer Card Features  8 independent 16-bit counters  8 programmable clock source  8 digital TTL outputs and 8 digital TTL inputs  Up to 20 MHz input frequency  Multiple counter clock source selectable  Counter output programmable  Counter gate function  Flexible interrupt source select  BoardID™ switch Introduction VTC334583 is a general purpose multi-channel counter/timer card for the PCI bus. It targets the AM9513 to implement the counter/timer function by CPLD. It provides eight 16-bit counter channels, 8 digital outputs and 8 digital inputs. Its powerful counter functions cater to a broad range of industrial and laboratory applications. y applications. The card features 12 programmable counter modes, to provide one shot output, PWM output, periodic interrupt output, time-delay output, and to measure the frequency and the pulse width. The VTC17489 shielded cable works well with VTC334583 to reduce noise. Its wires are all twisted pairs, and the input signals and output signals are separately shielded, providing minimal cross talk between signals and the best protection against EMI/EMC problems. For easier con.guration, VTC334583 supports Plug & Play, and have also been equipped with a DIP switch that helps de.ne each card’s unique identity when multiple identical PCI cards have been installed in the same computer. The BoardID switch is very useful when you build your system with multiple identical PCI cards. With the correct BoardID switch settings, you can easily identify and access each card during hardware con.guration and software programming.
