Is this acceptable > Since Jeff Eppler recommended my boards, I want to point out that the 300,000 count/second limit on my boards is a VERY conservative spec. The encoder counter is clocked at 1 MHz, so that if there is not a lot of jitter and noise, it can count easily at 500,000 counts/second. Where it becomes a problem is if the encoder signal contains a lot of noise and timing jitter. I can up the clock rate to the encoder counter to raise this limit if needed. Firmware is an 8-pin DIP plug-in, so field updates are quite possible.
I don't want to disparage anyone else's products, but we have gone to great lengths to make our boards work with the variety of parallel port chips used on various motherboards.
