Any LocoNet throttle can be used with your WTL12. Simply plug the LocoNet throttle into either LocoNet port on the back of your WTL12 or into any LocoNet or Throttle Jack anywhere on your LocoNet system. If you want to be able to plug in a throttle at a remote location, we recommend using a UP5 Universal Panel.
Your WTL12 can handle up to 6 LocoNet Throttles. If you need to run more than 6 throttles, you can move up to a Digitrax Command Station with additional capacity. You can continue to use your WTL12 as a throttle and booster with any command station on your Digitrax LocoNet system.
