ABOUT V605
The V605 is a single-width, C-size, register-based, VXIbus module that contains six 24-bit, optically isolated counters. A signal in the range of +2.4 V to +5 V, with a 5 mA drive capability, is required to turn the optical isolator on. All inputs accept this as a logical "one" and clock the counter chains on the zero-to-one transition. The minimum clock pulse width is 100 ns. Counting can be suppressed by the application of a low-true, TTL-level signal at the front-panel Inhibit input.
