Question: Are the cables included?
Answer: Thank you for your your inquiry,

The Aten CS1308 ships with a KVM cable for the console that serves as the intermediary between the switch and the connected user station computer. A separate custom KVM cable is required for each source-computer connection. Custom cables of various lengths and interface (USB or PS2) are listed in the Accessories tab. For reference you can find the Cable Connection Diagrams on page 14 of the Aten CS1308 manual.

Question: I want to use 1 keyboard and 1 mouse to control 8 workststions thru kvm. Is it possible with cs1308? I see only vga ports at the rear side. Which cable i need to achieve this?
Answer: Thank you for your inquiry,

You can indeed control 8 work stations / PCs through the CS1308. The rear of the KVM actually uses proprietary all-in-one DB-15 connectors (similar connector to VGA but different pin-out). You would use these all-in-one KVM cable with the KVM which break out from that 1 DB-15 connector into the VGA + PS2 or USB connectors on the other side.
