Does the HDL300 system support bring your own device options?

The HDL300 system does not initially support “bring your own device” (BYOD) options, but it can be integrated with additional equipment to support such scenarios.

Cell phone and portable device connections with the HDL300 system over USB

The HDL300 system can connect to cell phones (or portable devices such as tablets) with a proper USB OTG (on-the-go) interface. Refer to your device manual or support web page to see if your model and operating system will support USB OTG and audio connections. 

Some cell phones and portable devices have OTG support through either a USB micro interface or a USB Type C interface. In this configuration, the device could be used to place a call through either the cellular phone network or through the internet via VoIP (Voice over Internet Protocol) software. Using this connection method can allow the user to create an impromptu meeting, where the call can be placed quickly and easily through the device. For local participants, the HDL300 system simply becomes a microphone and speaker for the portable device.

With a USB Type C (or USB micro) to USB-B male OTG cable, connect the portable device to the connect module. Refer to the manual of the portable device for compatibility and any configuration settings within its software that may be required.

Android™ portable devices 

USB OTG audio connections were not supported in Android devices until version 5 (Lollipop). Therefore, all Android versions prior to version 5 will not support the HDL300 system. However, even if the portable device does have Android version 5 or later, this does not necessarily mean USB OTG audio will be supported. There are some differences in the implementation of the operating systems and applications between device makes and models. Refer to your device manual or support web page to see if your model and operating system will support USB OTG and audio connections.

Configuration may be required on some Android devices to enable the USB audio. Check for the following items under the Developer options menu.

  • Select USB configuration menu item – choose the “Audio Source”
  • Disable USB audio routing menu item – set to “Off”

Windows® portable devices

USB OTG audio connections are supported on the Windows platform. Room Manager would have to be configured so the HDL300 system is selected for the recording device (microphone) and playback device (speaker).

Apple™ portable devices

Currently, USB OTG audio connections are not fully supported on the macOS® platform for portable devices such as the iPhone® or iPad®. Although a lightning to USB adapter can be obtained (model #: MD821ZAM/A), only certain software will allow use of the HDL300 system’s microphones or speakers as a recording or playback device. Software such as Skype® for Business and FaceTime® do not switch the audio channel to the HDL300 system and use the microphone and speaker of the portable device.

Use of a USB switch

A USB switch (not hub) could be used to select between an in-room dedicated computer and the cell phone for a flexible configuration. Ensure that the switch supports USB 2.0 Hi-Speed.

Bluetooth® connections

The HDL300 system does not have integrated Bluetooth and does not natively support Bluetooth connections.
