How to sync multiple RL-C21 devices in 3 steps

Testing spaceships, cars, planes and other massive objects for resonance may require multiple interconnected controllers. In this article we will guide you through the process of connecting up to 8 RL-C21 devices in 3 simple steps.

Step 1

Connect your controllers to an Ethernet hub that is plugged into your PC.

Step 2

Pair the controllers using the first synchronization Ethernet port. Install a terminator stub in the second port to prevent possible errors.
