It has a single button user interface and returns a simple pass or fail for USB - RS232 designs. The executable version is hard-coded for use with the default VID (0x0403) and PID (0x6001) and must be re-compiled to be used with other VID and PID combinations.

Web2. TTL values are determined by the remote machine. For example, if you ping a Linux machine, its originating TTL value is 64. Depending on how many routers it crosses to get … WebApr 8, 2015 · Since the first buffer has 0 - 5 volt outputs, I chose a family with 0 - 5 volt inputs. The 120 ohms is a series terminator, and the value is a typical impedance for UTP. You can still use the transmitter/receiver idea, since 3 wires twisted together in a cable will have an impedance, and ~100 ohms is a good starting point.
