CC bec, 2.4 GHz and interference

[miniGranis]

I have plans to put my CC bec in my Tekno receiver box together with my 2.4GHz receiver.
Has anyone tried that, will I get interference,glitching,reduced range or will the 2.4 GHz receiver be ok ?

It should be fine - mine are very close together - just depending on your age of CC bec you may have to plug it into channel 3 not the bat slot or use a y splitter off of any channel.

The early becs caused an issue with the signal on the BEC and the arming of the rx.

Thanks the bec was ordered from Mike about 4 weeks ago.

May be an old one then they changed mid dec - worst case just use channel 3...

The issue they had with the BEC only happens when using Spektrum receivers because when you bind a Spektrum receiver you have to short two wires (using bind plug) on the battery slot so that the receiver knows you want to bind. The CC BEC uses those same wires for programming so when you plug it into the battery slot it automatically shorts the wires and the receiver thinks you want to bind. This is why the issue is solved when you plug the BEC into any other slot. This has been fixed by Castle though so any of the new BEC's do not have this problem.

So if you are using any 2.4Ghz receiver other than Spektrum then you will not have any problems.

I just read that over at the Castle website:

Castle has learned of a slight incompatibility of the CC BEC with the SPEKTRUM AR 6100, 6200, 7000, and JR 790 ScanSelect receivers. There is a very easy work around for our customers who already have the CC BEC and we are making modifications to the components of all new CC BECs that are built from Nov. 1, 2007, forward.

The simple explanation is that the CC BEC, like most Castle products, is designed to be USB linkable via the signal wire on the servo connector. As part of that, the CC BEC will pull the signal wire to ground unless it is sending a signal on that line. Nothing out of the ordinary with this. Similarly, the Spektrum team designed these receivers to look for a grounded signal pin on the battery port in order to initiate binding. Nothing strange there either. Castle does something similar with our Berg receivers. The problem is that the two designs result in the CC BEC triggering the receiver's binding mode immediately upon power up. We have redesigned the CC BEC to facilitate the USB activities without initiating the binding mode.

For those of you with the affected CC BECs and Spektrum receivers there are at least three solutions:

Remove the orange signal wire from the CC BEC RX power lead before you plug the lead into the battery port on the receiver.
Plug the entire/intact lead from the CC BEC into any other port on the receiver.
Use a "Y" connector to plug the entire CC BEC lead into any port other than the BATT port on the receiver.
If you are unsatisfied with any of the above solutions, please simply send your CC BEC to Castle for upgrade.

Please note that this incompatibility will be immediately apparent. There are no known issues after the system is successfully powered up.

Thanks!
