Comes with 20 E3M to E3M 3 - inch 3 - wire normal jumpers.

This patch bay is easy to use. First, connect the E3M to E3M normal jumpers to the appropriate ports. When using, make sure the connections are secure to avoid signal interruptions. Keep the patch bay in a dry and clean environment. If there is dust, use a soft, dry cloth to gently wipe it. Don't use sharp objects to touch the ports to prevent damage. This will help maintain its performance and extend its lifespan.
