SMART Response
If the provided 6' (1.8 m) USB cable attached to the receiver isn’t long enough, use active USB extender cables, USB extenders or hubs.
This graphic shows the SMART active USB extension cable (Part No. USB-XT).
In some cases, you can use up to four cables to extend the length to about 80' (25 m), which is the limit of the USB specification. Passive USB extension cables aren’t supported.
Alternatively, USB extenders that use Cat 5 cabling can extend the range to approximately 325' (100 m) at a much higher cost. The more economical SMART USB extender pair (Part No. CAT5-XT) can extend the USB connection up to 120' (36.6 m) on Windows computers or 90' (27.5 m) on Mac computers using an RJ45 Cat 5 cable.
These units require that you use the provided 6' (1.8 m) cables or use cables and connectors that meet the same specifications. Impedance mismatches and poor connections can cause signal degradation and performance problems.
Note
Some computers use internal active hubs to provide more USB receptacles. The computer’s operating system could interpret these internal hubs as external devices, limiting the number of USB extenders you can use.
