Como habilitar canales digitales de la NI usb 62XX para ser utilizados como contadores?

[LauraPrieto]

Mi consulta es relacionada con la USB DAQ 6216, la cual cuenta con 2  canales  habilitados como contadores y que pueden ser utilizados para medir la posición angular de 2 encoders de doble cuadratura, en este momento estoy tratando de desarrollar un VI en el el cual necesito tomar la medida de  3 encoders (todos con  canales A y B)  y generar señales PWM, para controlar el movimiento de 2 motores con ejes solidarios a los ejes de los encoders respectivamente, ¿cómo habilitar canales (pines de la tajeta) de entradas digitales para que cumpla la función de contradores para un encoder adicional ?

You're going to need another DAQ device.  3 encoders will require 3 counters.  2 PWM signals will require 2 more counters for 5 counters all together.

Assuming you need USB, add an X-series USB board to get 4 more counters (look for USB-63xx).  I'd connect all the encoders to the X-series board because I know the X-series board will have a good-sized hardware buffer.  Many M-series boards (USB-62xx) don't.

Hi Kevin_Price, thank you for answering but at Screw Terminal Pinout said that there are a Programmable Function Interface and these terminals can be individually configured as a PFI terminal and the PFI terminal can be use to counter/timer inputs.
I just need one more counter because I can generate a PWM signal with an analoge ouput and a signal generator.

The PFI pins can be used as inputs *TO* the 2 counter / timers, but they do not have the ability to act as counter / timers by themselves.

With 2 counters, you can only read 2 encoders at a time.
