Important news regarding wireless upgrades: Due to parts changes ALL NEW wireless cabs or wireless upgrades will now be wireless version 1.7. The good news: your EXISTING version 1.5 wireless cabs will NOT need an update! They will work exactly the same. The bad news: If you have a new version 1.7 wireless cab, your RB02 radio receiver MUST be updated to version 2.5 to work correctly. That update is $30 + return shipping with a turnaround time of about 4 weeks. We sincerely apologize for the required RB02 v2.5 update, but time marches forward in the electronics industry. It is always a challenge to stay up to date.    To get radio firmware version on a Pro Cab or converted Power Cab, turn off the cab, then turn off the DCC system. Hit the red e-stop button to turn the throttle back on. You will see the wireless version on the screen. The current WIRELESS radio version is 1.7. Version 1.5 cabs DO NOT need to be updated! However, If you have a new cab or updated cab with wireless version 1.7 the RB02 must be version 2.5. Note that this is different from the Pro Cab keypad and display firmware which is always 1.3.   ============================================================== Any cab that is NOT version 1.5 or higher will need a new wireless board with internal antenna installed. The cost for this is $106+ return shipping. You will also need to send in your RB02 radio base station if it is not version 2.5. Check the sticker on the bottom. If you have a Cab06, the RB02 must be version 2.5. To upgrade your RB02 to the current wireless firmware is $30 per item + return shipping. ======================================================= NCE does not sell wireless self installation parts or kits to the general public.
