What is the maxmum distance I can use between the PCs ?
Explain the SyNET Extension Cable.

The SyNET PC Clone and SyNET Internet Sharing Kit (USB) are both ten (10) foot long but it can be extended to a maximum of forty four (44) feet using TWO (2) SyNET Extension Cables on each ends of the SyNET PC Clone or SyNET Internet Sharing Kit (USB). A USB Repeater can be used for longer extensions without loss of speed.
