Frequently Asked Questions - RCH240 Yealink

How do I connect the RCH240 to my display?

Connect the RCH240 to your display using an HDMI cable (not included) into the HDMI out port. For video from an external source, use the HDMI in port. Ensure the display is set to the correct input source.

Does the RCH240 support Power over Ethernet (PoE)?

Yes, the RCH240 is PoE+ (802.3at) compatible. When connected to a PoE+ switch, no separate power adapter is required. Otherwise, use the included 48V DC adapter.

Can I use the RCH240 with Microsoft Teams?

Yes, the RCH240 is certified for Microsoft Teams. It also works with Zoom, Skype for Business, and Cisco Webex. Plug-and-play via USB-C or using Yealink's USB connect mode.

How do I adjust the camera angle?

The RCH240 has a manual tilt mechanism. Gently tilt the camera unit up or down as needed. For pan and zoom, use the remote control or the Yealink management software.

What is the maximum microphone pickup range?

The built-in 8-microphone array can pick up voices up to 8 meters (26 feet) away in a typical office environment. Performance may vary based on room acoustics and noise.

How do I update the firmware on the RCH240?

Download the latest firmware from the Yealink support website. Connect the RCH240 to your network via Ethernet. Access the web interface using the device IP, then navigate to Maintenance > Upgrade and upload the firmware file.

Can I mount the RCH240 on a wall or TV?

Yes, the RCH240 comes with a desktop stand. Optional wall and TV mounts are sold separately. Use VESA-compatible brackets for TV mounting. Ensure the mount can support the device weight (1.5 kg).

Why is there no audio from the RCH240 speaker?

Check that the volume is not muted on the remote or the device. Ensure the display is set to output audio via HDMI or that the RCH240 is selected as the audio device in your conferencing app. Also verify that the HDMI cable supports audio.

What should I do if the device does not power on?

First, check the power connection. If using PoE, ensure the switch provides PoE+ (802.3at) and the Ethernet cable is securely connected. If using the adapter, confirm the adapter is plugged into a working outlet. Try a factory reset by pressing the reset button (use a paperclip) for 10 seconds.

Is the RCH240 compatible with third-party conferencing software?

Yes, the RCH240 works as a USB camera and speakerphone, making it compatible with any software that supports standard USB HID/UVC devices. Examples include Google Meet, RingCentral, and GoToMeeting.

USER MANUAL RCH240 Yealink

Access the Switch Web Interface

Introduction

To set up your Pro AV system, a switch with multicast capability and audio and video management functions is required. The switch must be compatible with the Yealink AVONE solution. Yealink RCH80/RCH240 is the recommended option.

• Network: Multicast-capable AV-managed switch compatible with Yealink AV One audio/video solution, enabling plug-and-play deployment for basic scenarios.
  • Transmission rate: Supports at least Gigabit (1Gbps) speed.

• Features:

• Supports PoE power delivery (Energy-Efficient Ethernet/EEE disabled by default).

• Multicast configuration: IGMP snooping, IGMP querier, and IGMP query interval.
• Supports unknown multicast discard and fast leave functions.

This chapter introduces the configuration of the network environment in the Pro AV system, using RCH240 as an example. The configuration method for RCH80 is the same.

Connect

- Connect your computer's Ethernet port to any port on the switch using a network cable.

Configure the IP Address of PC

- Open Network Settings on your PC and manually configure the USB network adapter/IP address:

• IP Address: 192.168.0.100 (must be in the same subnet as the switch's management IP)
• Subnet Mask: 255.255.255.0
• Default Gateway: only required for cross-subnet management.

Access the Web User Interface

Open a browser (Chrome/Firefox recommended) and enter the switch's default 1.

management IP address (http://192.168.0.1).

Change the login password upon first login, then log in again using the new password (The 2. default username and password are admin).

Cascaded Setup

Introduction

After factory default or a factory reset, the switch's default IP address is 192.168.0.1 and IGMP Auto Query is enabled by default. However, in a cascaded network, identical switch IPs can prevent logging into the target switch. Also, multiple simultaneous queries can cause multicast anomalies on devices, leading them to leave groups. Therefore, when cascading RCH80 and RCH240, you must change the switches' IP addresses and disable duplicate IGMP Auto Query functionality.

1. Disable the Auto Query on Cascaded Switches

In a cascaded topology, IGMP Auto Query should only be enabled on the primary/master switch to avoid conflicts.

In a multicast network, IGMP querying performs these key functions:

• Sends query packets to identify devices that need to receive multicast streams
• Maintains correct multicast membership state

• Ensures efficient delivery of multicast streams
  Open the switch web user interface.1.

• Go to L2 Configuration > IGMP Snooping, and set Enable Auto Query to Disable.

2. Resolve IP Address Conflicts

If multiple switches are cascaded, change each switch's management IP to avoid address conflicts.

• All switches use the default IP 192.168.0.1.
• Change the second switch to 192.168.0.2; for additional RCH80 or RCH240, use 192.168.0.3

RCH240 User Guide_Switch Configuration

through 192.168.0.255.

- Keep the subnet mask as 255.255.0.0.

Switch Number Recommended Management IP Subnet Mask
Switch #1 192.168.0.1 255.255.0.0
Switch #2 192.168.0.2 255.255.0.0
Switch #3 192.168.0.3 255.255.0.0
...... 192.168.0.x (x ≤ 25) 255.255.0.0

1. Go to L3 Configuration > VLAN Interfaces and IP Addresses, then click Edit.

1. Edit the IP address details, then click Save All when finished; otherwise the device will revert to the last saved configuration after reboot.

After saving, open back into the switch web user interface using the new IP address.3.

3. Connect Cascade Switches

Once the switch configurations above are complete, you can cascade-connect the switches with Ethernet cables. We recommend using a daisy-chain topology, as shown below. We do not recommend a star-chain topology, as it may cause communication issues.

In a cascaded switch network:

• High-bandwidth video devices (e.g., EN300/DE300/AVHUB) must be connected to the same switch;
• Audio devices (e.g., AP08/CM50/CS10-D) should be connected to the same switch whenever possible; if not feasible, connect them to a switch adjacent to the one hosting the AP08 to reduce inter-switch latency.

Example: AVONE divisible room switch connections

• All EN300/DE300/AVHUB connect to the same switch;
• AP08/CM50/CS10-D devices are primarily deployed on switch #3; due to limited switch power, some CS10-Ds need to connect to the next switch, #4;
