16-Port VGA KVM Switch

The Aten CS1716A provides direct control of sixteen computers from a single VGA, PS/2 or USB console. It suits server rooms and labs where administrators need local, hardware-level access to multiple rack-mounted systems without network dependency.

VGA 2048 x 1536 and Daisy-Chain Limits

Video bandwidth supports 2048 x 1536 resolution through the analogue VGA interface, with DDC2B monitor communication. The DB-25 daisy-chain port allows linking additional units to reach a theoretical maximum of 512 connected computers, though each hop adds cable length and potential signal degradation.

Console Emulation and Scan Headroom

Keyboard and mouse emulation covers both PS/2 and USB protocols, keeping all sixteen ports responsive during switching. The on-screen display, hotkeys and front pushbuttons select targets, while the auto-scan interval runs from one to 255 seconds. Power draw is 5.31 watts at 5.3 volts, operating between zero and fifty degrees Celsius.

Questions about this item

Should I choose the 16-port model or daisy-chain multiple units for more servers?

The switch connects 16 computers directly and supports up to 512 total when daisy-chained via the DB-25 port, so a single unit suits 16 servers while larger deployments add units.

What does the 2048 x 1536 video rating mean for my monitor?

It supports resolutions up to 2048 x 1536 with DDC2B, so most VGA monitors will display at their native resolution without scaling issues.

What does the SPHD-15/17 KVM interface cap in practice?

Each of the 16 SPHD-15/17 ports carries VGA video plus PS/2 or USB keyboard and mouse, limiting each server connection to analog video and legacy USB or PS/2 input.
