The RC Bus was designed to multiply RC Multi 10 pin connector on the RCE Multi 2 in order to connect up to three other devices or sensors to it. Every connector has the same pin-out as connector on the RC Multi module.
You will require this extension socket lead if you are going to connect more than one sensor to you RC Multi 2
Please note if you want to connect the Multi 2 or other RC devices to your PC for downloading Flight Logs or updating firmware, it can not be done through the RC Bus, it must only be done directly through the USB/10pin lead supplied pluged directly into the Multi 2
