Display, Data, Memory Cards and Charging through One USB-C Port
CM511 combines the connections commonly required by mobile professionals, photographers, content creators and hybrid workers in one compact adapter.
1× HDMI 2.0
Connect one compatible monitor, television or projector at resolutions up to 4K@60Hz.
2× USB-C 3.2
High-speed data ports for compatible USB-C SSDs, drives, card readers and peripherals.
1× USB-A 3.2
Connect compatible flash drives, external storage, keyboards, mice and USB-A accessories.
1× SD Reader
Access compatible full-size SD, SDHC and SDXC memory cards.
1× microSD / TF Reader
Read compatible microSD, microSDHC and microSDXC cards without a separate adapter.
1× USB-C PD Input
Connect a compatible USB-C charger to power the host device while the hub remains connected.
Transfer Compatible Data at up to 10Gbps
Use the two USB-C data ports and USB-A data port with compatible high-speed SSDs, drive enclosures, flash drives, card readers and professional accessories.
For 10Gbps Operation
- The host USB-C port must support USB 10Gbps.
- The peripheral must support USB 10Gbps.
- The peripheral cable must support the required speed.
- The connected storage must be sufficiently fast.
- Actual throughput is lower than the theoretical link rate.
USB Devices Share the Available Upstream Bandwidth
All connected USB devices communicate through the hub’s single attached USB-C host cable. Simultaneous transfers divide the bandwidth available from the host computer.
Actual Performance Depends On
- The host USB-C controller and port specification
- The number of simultaneously active devices
- External-drive and storage performance
- File size and operating-system overhead
- Power available to the connected peripherals
Connect One External Display at up to 4K@60Hz
Connect a compatible HDMI monitor, television or projector for presentations, productivity, entertainment and creative work. Supported resolution and refresh rate depend on the host device, operating system, display and HDMI cable.
4K@60Hz
Smooth Ultra HD output with a compatible source, monitor and HDMI cable.
HDR10
Passes compatible HDR10 video when the source, application, content and display support HDR.
HDCP 2.2
Supports compatible protected video playback across a compliant source, software and display chain.
The Host Port Must Support DisplayPort Alt Mode
A USB-C connector does not automatically provide video. HDMI output requires a host USB-C or Thunderbolt port capable of carrying a DisplayPort video signal.
Before Connecting a Display
- Confirm DisplayPort Alt Mode or Thunderbolt video support.
- Use a suitable HDMI 2.0 cable for 4K@60Hz.
- Confirm that the monitor supports the selected mode.
- Update the graphics driver and operating system.
- Enable the required display mode in system settings.
Mirror or Extend Your Workspace
Mirror Mode
Display the same presentation, video or application on the host and external screen.
Extended Desktop
Use the connected HDMI display as an additional workspace where supported by the host.
Single HDMI Display
The hub provides one HDMI output and directly supports one external display.
Transfer Photos and Videos from SD and microSD Cards
Separate SD and microSD/TF slots support compatible camera, drone, action-camera, dash-camera and mobile-device memory cards. Both card slots can be accessed together with a supported host system.
Full-Size SD
Supports compatible SD, SDHC and SDXC memory cards.
microSD / TF
Supports compatible microSD, microSDHC and microSDXC memory cards.
Simultaneous Access
Read compatible SD and microSD cards at the same time without swapping slots.
Transfer Speed Depends on the Card and Host
Memory-card performance depends on the card standard, rated read/write speed, file system, host USB connection and whether both slots are active simultaneously.
For Better Card Performance
- Use a high-speed SD 3.0-compatible card.
- Connect the hub to a high-speed USB-C host port.
- Use cards from reliable manufacturers.
- Safely eject cards before removing them.
- Avoid interrupting power during file transfers.
Up to 100W Power Input with Approximately 95W for the Host
Connect a compatible USB-C Power Delivery charger to the dedicated PD input to charge the host laptop or tablet while using the hub’s display, data and card-reader functions.
Full-Power Requirements
- A compatible USB-C PD charger rated up to 100W
- A suitable 5A E-Marker USB-C charging cable
- A host device supporting USB-C Power Delivery input
- The charger connected to the dedicated PD port
- Charging power accepted according to the host’s limit
Charging Speed Is Determined by the Complete Power Chain
The hub accepts up to 100W at its PD input, but the host receives only the power it supports. A lower-powered charger or cable results in lower host charging.
Important PD Notes
- A USB-C charger is not listed as included.
- A charging cable is not listed as included.
- The hub uses a small portion of the input power.
- The PD port is a power input, not a data port.
- Connected USB peripherals share power supplied by the host.
For Compatible MacBook, Windows, Chromebook, Tablet and USB-C Systems
Data, charging and display functionality depend on the capabilities of the connected USB-C host port. A compatible Thunderbolt 3 or Thunderbolt 4 port can operate the hub as a standard USB-C device.
MacBook & Mac
