Product overview

Overview

A clear view of the product before you connect it

CM511 is a compact seven-port hub for users who need faster storage connections than a 5Gbps hub provides. Two USB-C and one USB-A USB 3.2 data ports support up to 10Gbps theoretical with a compatible host, cable and peripheral.

One HDMI 2.0 output supports up to 4K at 60Hz and a compatible HDR10, HDCP 2.2 and 3D signal path. Separate SD and microSD readers can be accessed together, while the dedicated PD input keeps a supported laptop or tablet charged.

The host connection is still one shared USB-C link. Simultaneous storage transfers divide bandwidth, and actual performance depends on the host controller, drive, file workload and available power. A 100W input can provide up to about 95W to the host after hub consumption.

USB 3.2 PERFORMANCE

Move compatible files at up to 10Gbps theoretical

Use the two USB-C data ports and USB-A data port with compatible SSDs, drive enclosures, flash drives, card readers and professional peripherals. Reaching a 10Gbps link requires a 10Gbps host port, peripheral, cable and storage device.

Real throughput is lower than the theoretical link rate. All connected USB devices communicate through the attached host cable, so concurrent transfers divide the available upstream bandwidth.

  • Two USB-C 3.2 data ports
  • One USB-A 3.2 data port
  • Up to 10Gbps theoretical
  • Shared host bandwidth
  • Actual speed depends on storage and workload

SKU 45521: The two USB-C and one USB-A data ports are specified up to 10Gbps theoretical with compatible equipment, while all devices share the upstream link.

HDMI 2.0 DISPLAY

Connect one external screen at up to 4K 60Hz

Connect a compatible monitor, television or projector for presentations, productivity, video and creative work. The host operating system controls mirror or extended-desktop mode.

Supported resolution, HDR, protected playback and refresh rate depend on the source, USB-C video capability, content, application, HDMI cable and display. The host port must provide DisplayPort Alt Mode or compatible Thunderbolt/USB4 video.

  • One HDMI 2.0 output
  • Up to 3840 × 2160 at 60Hz
  • Compatible HDR10 path
  • Compatible HDCP 2.2 path

The dedicated PD input accepts up to 100W from a suitable charger and can provide up to approximately 95W to the host after hub consumption. Final charging depends on the charger, 5A E-Marker cable and host limit.

  • SD + microSD simultaneous access
  • Up to 100W PD input
  • About 95W maximum host charging
  • PD port is power input only
  • Charger and charging cable not included

Important limitations

Check before buying

Check these points before ordering or connecting:

  • The host port must support USB 10Gbps to reach the maximum data-link claim.
  • HDMI requires DisplayPort Alt Mode, USB4 display output or compatible Thunderbolt video.
  • This model directly supports one external display through HDMI.
  • The two downstream USB-C ports are data ports; they are not monitor outputs, 100W charging outputs or downstream Thunderbolt ports.
  • All USB devices share one upstream connection, so concurrent transfer rates fall.
  • 100W is maximum PD input; about 95W is the stated maximum for the host and actual delivery can be lower.
  • This model has no Ethernet, VGA, DisplayPort or 3.5mm audio connector.
  • A PD charger, charging cable and HDMI cable are not included.

Guided connection

Setup and usability guidance

Match each USB-C port to its correct role

  1. Confirm the host port supports USB data, the required 10Gbps rate, external video and charging as needed.
  2. Connect the attached braided USB-C lead directly to the host.
  3. Connect a compatible PD charger and rated cable to the dedicated PD input, not to a USB-C data port.
  4. Connect HDMI, select the display input and choose a supported mirror or extended-desktop mode.
  5. Connect high-speed storage to a data port and verify the host negotiates the expected link.
  6. Insert SD and microSD cards correctly and wait for them to mount before transferring files.
  7. Safely eject all storage and cards before disconnecting the hub.

Good practice

Do and avoid

What to do

  • Use a 10Gbps-capable host, peripheral and cable chain for high-speed transfers.
  • Use a suitable HDMI 2.0 cable for 4K60.
  • Use a compliant 100W-class PD charger and 5A E-Marker cable when maximum host charging is required.
  • Keep the aluminium enclosure uncovered to distribute normal operating heat.
  • Use safe-eject before removing drives and cards.
  • Test high-speed devices one at a time before starting concurrent transfers.

What not to do

  • Do not connect the charger to a USB-C data port.
  • Do not expect a USB-C data port to drive a monitor.
  • Do not call the hub a Thunderbolt dock or expect 40Gbps functions.
  • Do not cover the housing during sustained transfer, HDMI and PD use.
  • Do not interrupt file writes or remove power during card transfers.
  • Do not continue use with damaged, loose, wet or unusually hot connectors.

Safe operation

Warnings and limitations

Safety note 1

Mild warmth is normal because the aluminium enclosure distributes heat from data, video and charging circuits. Keep it open to airflow.

Safety note 2

The theoretical 10Gbps rate is not a guaranteed file-copy speed. Storage performance, protocol overhead, host controller and concurrent devices reduce throughput.

Safety note 3

4K60 and HDR require a compatible end-to-end path. A blank or downgraded image often indicates host-port, cable, content or display limitations.

Safety note 4

PD power is negotiated. An underspecified charger or cable reduces charging and can make power-hungry peripherals unstable.

Safety note 5

Removing a card or drive during a write can corrupt files. Use safe-eject and wait for activity to stop.
