Selected user-facing port groups only; not a complete physical inventory. Counts refer to manufacturer documentation, not a hardware inspection.

Same connector form, different documented roles

USB-C: Thunderbolt host port — Upstream host · Downstream Thunderbolt ports — Downstream · USB-C data ports — USB downstream

Do not transfer a capability from one location to another merely because the connector outline matches.

× 1
Upstream host

Thunderbolt host port

One Thunderbolt connection is designated for the host. CalDigit rates host charging up to 98 W; the connected host and cable determine the actual result.

Seeds identity, connector and source link only. Task support is not inferred.

× 2
Downstream

Downstream Thunderbolt ports

Two downstream Thunderbolt connections are separate from the host connection and the ordinary USB-C data group. CalDigit lists up to 15 W each; suitable display connections remain host-dependent.

Identification only. This port group cannot launch the scoped planner.

× 3
USB downstream

USB-C data ports

Three ordinary USB-C data ports, documented at up to 10 Gb/s: the manual’s front-left port is rated up to 20 W, the other two up to 7.5 W each. CalDigit’s data-only wording distinguishes these from display paths; it does not mean no power. This remains one aggregate group, not a locator for one specific socket.

Read before using the profile

  • Network, audio and DC input are outside this selected inventory. The added output ratings do not establish a charger allocation or negotiated host power.
  • A dock profile seeds an unresolved dock stage; no number of documentation links unlocks an arbitrary dock compatibility verdict.
  • The stable usb-c group still represents all three ordinary USB-C sockets. It has not been silently reassigned to one socket; no unique physical location is assigned to that aggregate group.
  • V84 inspected the TS4 manual and reinspected S062/S064 on 2026-10-08. Original profile and source dates are retained; this is not an independent review or a refreshed complete inventory.
