Set up the Canon BG-R20EP battery grip on your EOS R5 II for wired LAN transfers. Follow these steps to configure the 2.5G Ethernet connection for a tethered studio workflow.

Quick answer

To set up the BG-R20EP battery grip for wired LAN on the EOS R5 II, attach the grip, connect an Ethernet cable to its 2.5G Base-T port, and configure the camera's network settings for a stable wired connection. This setup is ideal for tethered studio workflows where reliability and speed matter.

Why use the BG-R20EP's wired LAN instead of Wi-Fi

The BG-R20EP adds a 2.5G Base-T Ethernet port, which provides a physical connection that is generally more stable and faster than Wi-Fi for transferring large files. In a studio environment with many wireless devices, a wired connection reduces interference and ensures consistent transfer speeds. However, it also tethers your camera to a cable, limiting mobility. For stationary shoots, this is a worthwhile trade-off.

When the BG-R20EP is not the right choice

If you need to move freely around the set or shoot in locations without network infrastructure, the wired LAN feature may go unused. The grip still offers improved handling and battery capacity, but the LAN port adds bulk and cost. Consider whether your workflow truly requires wired networking before investing.

Step-by-step setup for wired LAN with the BG-R20EP

Attach the BG-R20EP to the EOS R5 II: Remove the camera's battery door and slide the grip onto the body, tightening the locking wheel securely. Make sure the grip's contacts align with the camera's. Common mistake: not removing the battery door first, which prevents proper attachment. Check that the grip is firmly attached and the camera recognizes it (battery info should show both batteries).
Connect an Ethernet cable: Plug a standard Ethernet cable into the 2.5G Base-T port on the grip and connect the other end to your network router or switch. Use a cable that supports the speed you need (Cat5e or higher). Common mistake: using a damaged or low-spec cable that limits throughput. Verify the link LED on the port lights up, indicating a physical connection.
Configure the camera's network settings: On the EOS R5 II, go to Menu > Network > Wired LAN settings and enable the wired connection. Set the IP address to automatic (DHCP) or manual as required by your network. Common mistake: forgetting to disable Wi-Fi, which can cause conflicts. Confirm the camera obtains an IP address and shows a connected status.
Test the connection with a transfer: Use the camera's FTP transfer or EOS Utility to send a test image. Monitor the transfer speed and stability. Common mistake: not testing before a critical shoot, leading to unexpected issues. If transfers fail, check firewall settings or cable integrity before the session.
