ATEN KE8900ST Slim HDMI KVM Over IP Transmitter
Overview
The KE8900ST is ATEN's slim-form transmitter unit for HDMI-based KVM over IP deployments — the source-side half of a point-to-point or matrix extension system. Install it at the host computer to capture HDMI video up to 1920×1200 at 60Hz and USB keyboard/mouse signals, then push them across a standard IP network to a paired receiver. With latency under 48ms, it covers control room, digital signage, and broadcast rack environments where lag is operationally disqualifying. The slim profile supports recessed and rack-mount installation, making it a natural fit in space-constrained AV-over-IP racks. Firmware v7.5.741.002 (released 2023-07-24) applies to the shared ke6900st/ke8900st/ke9900st line. For more in the ATEN product line, browse the full catalog.
Compatibility
The KE8900ST pairs with ATEN's KE8900SR receiver and integrates into the ATEN KE Series KVM over IP matrix — including the KE6900ST, KE8900ST, and KE9900ST slim transmitter family sharing a common firmware image. It operates over a standard Gigabit Ethernet LAN via its single RJ-45 port, making it compatible with any managed or unmanaged switch carrying the KVM over IP VLAN. USB keyboard and mouse devices connect directly to the transmitter for host-side HID pass-through. For KVM switches and extenders, this unit fits deployments where the display source and operator console are separated by structured cabling. Consider pairing with a Gigabit PoE network switch if you need to centralize power delivery in the rack.
Installation Notes
Supports recessed or rack-mount configurations — verify chassis cutout dimensions against ATEN's published mechanical drawings before ordering. The semi-recessed reset pushbutton requires a thin tool for actuation; plan for access clearance in tight rack builds. Humidity tolerance is 0–95% RH non-condensing: not rated for outdoor or high-condensation environments. Firmware updates are delivered via the shared zip package ke6900st-ke8900st-ke9900st-Slim-Matrix-v7.5.741.002.zip — one update file covers the full slim-matrix transmitter family. A single LAN port handles all IP traffic; ensure your network infrastructure provides adequate bandwidth if multiple KVM streams share the same switch uplink.
