Introduction
The PEX-TMC12A utilizes the PCI Express bus and is designed as an easy replacement for the PCI-TMC12A series without requiring any modification to either the software or the driver.
The PEX-TMC12A provides twelve 16-bit timers/counters (four 82C54 chips x 3 timers/counters), 16 TTL digital input channels and 16 TTL digital output channels. The two onboard clocks (8 M/1.6 M and 0.8 M/80 K) are jumper selectable and provide a highresolution clock source for timers/counters. Counters/timers can be used for industrial and laboratory applications such as pulse/ event/switch-toggle counting, frequency readings, elapsed time measurement, pulse-width measurement, PWM (pulse-widthmodulated) output, and pulse (square wave) and rate generation, etc.
The PEX-TMC12A includes a Card ID switch that enables the board to be easily recognized via software if two or more cards are installed in the same computer.
