Pierre-CNRS Posted March 14 Share Posted March 14 Hello, In the User's guide of the USB-QUAD08 Encoder Input Device, it is mentioned on the last page, that "I/O cables must be less than 3 meters (9.75 feet) in length." Is it really concerning the I/O cables and not the USB cable ? It seems in fact a short max length because, the encoders are often designed for 40m to 50m cable light using RS422 digital differential signals. Does anyone have any experience of this?

0 JRys Posted March 14 Share Posted March 14 That sounds like the maximum length of the USB cable. The USB Specifications section on page 31 of the user manual lists 3 meters or 9.84 feet. If your sensor has a differential output, you could run 300 meters or more of cable, assuming it is shielded twisted pair wire. Link to comment Share on other sites More sharing options...
