Eight-port USB and PS/2 KVM switch

The IOGEAR GCS1808 lets one keyboard, monitor and mouse control up to eight computers directly. It supports both USB and PS/2 host interfaces and works with Windows, Mac, Sun Solaris and Linux systems. Cascading additional units expands the total to 64 connected computers from a single console. This switch targets administrators managing multiple servers or workstations in a rack or lab environment.

Front-panel LEDs, OSD and hotkey switching

Computer selection is performed through illuminated front-panel buttons, an on-screen display menu or programmable hotkey sequences. The console attaches via a single SPHD-18 male connector while each computer links through an SPHD-15 female port. A bundled cable kit matches the SPHD connectors to standard VGA, USB and PS/2 plugs, so no extra adapters are required. Misaligned cables or missing pin adapters are the most common setup issues.

Stable video up to 2048 x 1536 under continuous use

The switch maintains DDC2B communication at 2048 x 1536 resolution during extended AutoScan cycles ranging from 1 to 255 seconds. Operating temperature is rated 0 to 50 °C with humidity up to 80 % non-condensing, and the unit draws 2.4 A from a 5.3 V DC supply. No active cooling is present, so airflow around the 22 x 9.63 x 5.5 inch chassis must remain unobstructed for sustained reliability.
