A custom kvm switch brief starts with the console plane, not with a headline rate. LinkScope Sourcing 17 is an independent sourcing partner. The desk asks factories to quote the same host count, display count, video interface, USB path, audio path, power input, and cable kit, then places those replies side by side.
Write the desk before the number. Note how many computers share one keyboard and mouse, whether each operator sees one screen or two, and whether the video path is HDMI, DisplayPort, DVI, or VGA. A 4K 3840x2160 at 60 Hz question is different from a 1920x1080 question, and a missing cable kit changes the delivered scope.

Each cell is a field the supplier should answer for the named model. This desk does not treat a family catalog as proof that the offered unit matches the cell.
Ask for the connector family on the console and on each host, the maximum resolution the supplier states, and whether EDID is emulated, learned, or left to the display. HDMI 2.0 is often discussed near 18 Gbit/s and DisplayPort 1.4 near 32.4 Gbit/s. Those are interface references, not a measurement this desk has made on a unit.
Separate keyboard and mouse HID from USB 2.0 at 480 Mbit/s and from a 5 Gbit/s or 10 Gbit/s USB 3.x peripheral path. State whether analog audio, a microphone, or neither is in scope. A switch that passes HID and nothing else is a different purchase from one that also passes a storage device. If a data switch shares the order, ask for forwarding rate and a Power over Ethernet budget in watts, such as 15.4 W, 30 W, or 90 W, on that separate line. Optical budget, wavelength, insertion loss, return loss, VSWR, impedance, frequency range, gain, MIMO, channel width, runtime, measurement accuracy, calibration traceability, connector mating cycle, and ingress protection are neighboring checks for optics, cables, radios, or meters, and they should not be copied onto the console model without a document.
Say if host cables, a console cable set, and power cords are included, excluded, or quoted as a separate line. Length matters: a 1.8 m set and a 3 m or 5 m set are not interchangeable in a deep rack. Ask for connector gender and whether the kit is bonded to the quoted model.
Require quantity, currency, per-console or whole-order basis, Incoterms, freight, duties, and the lead-time basis. An optional target budget should name its currency and whether it is per unit or for the order. A buyer preference for high-end, mid-range, budget, or undecided is not a verified factory grade.
A keyboard-video-mouse switch is not an Ethernet switch. Buyers still place both in the same rack, so the brief should keep the layers apart. IEEE 802.3 material checked as question context does not prove a console model.
Keyboard, video, mouse, and optional audio stay on this plane. Port count here means hosts and displays, not Ethernet ports. Hotkeys, front-panel buttons, and an on-screen menu are control methods to confirm, not features this site has certified.
Each computer needs a stated video output and a USB port for HID. If the supplier offers a dongle, record its connector and whether it is required for that model. A photograph of a similar dongle does not establish host compatibility.
If the same purchase also includes a data switch, ask separately for port count, port speed, switching capacity, forwarding rate, PoE standard and budget, uplink type, and management method. Power over Ethernet does not feed a local console switch unless a specific unit says so. Managed versus unmanaged belongs on that data-switch line, not on the KVM line.
Request a current datasheet tied to the exact manufacturer and model, plus cable drawings and any FCC or NRTL paperwork the supplier says applies to that item. ISO 9001, when offered, is a quality-system document for the plant, not a compatibility test of your hosts.
Read the procurement brief, then open inquiry cards or the RFQ form.
No. HDMI, DisplayPort, and DVI can share a physical family while differing in resolution, refresh, HDCP handling, and EDID. Ask the supplier which resolution table applies to the exact model, and which cable length was used when that table was written.
Count displays per console and hosts per switch. A two-host, four-display unit is not a substitute for an eight-host, two-display unit. The evidence guide walks through a 2-port quad-head check, and the dual-head page covers desk layouts.
State HID only, USB 2.0 peripherals, or a USB 3.x path. Keyboard and mouse traffic is small. A camera or disk is not. If the supplier cascades switches, ask whether the peripheral path survives the cascade.
Only after condition, firmware, remaining support, and warranty route are written as separate fields. New and refurbished are different commercial offers. This desk does not grade either one.
This form has no file attachment. Copy host names, display counts, interface types, cable lengths, quantity, destination, and requested timing into the requirement field. Mark unknown rows as open questions so each factory answers the same list.
