Wookman Posted September 6, 2022 Share Posted September 6, 2022 Rx was working ok. Tried to bind to a different Tx and it will not enter bind mode. It has lost its bind to the original Tx. It is definitely the Rx as I have bound another rx to both Txs successfully. Any clues that are more constructive than bin the receiver?

Don Fry Posted September 6, 2022 Share Posted September 6, 2022 Daft start, I assume you are say 15 feet away for the attempt. They can be very awkward if you are close. Something to do with bouncing radio waves off obstructions and swamping things. Quote Link to comment Share on other sites More sharing options...
Wookman Posted September 6, 2022 Author Share Posted September 6, 2022 Hi Don. The problem is getting the rx into bind mode in the first place. A different rx binds fine in the same environment. Quote Link to comment Share on other sites More sharing options...

Shaun Walsh Posted September 6, 2022 Share Posted September 6, 2022 Have you tried a different bind plug, could be a faulty connection? Quote Link to comment Share on other sites More sharing options...
Wookman Posted September 6, 2022 Author Share Posted September 6, 2022 Bind plug is good. Works on another rx. Quote Link to comment Share on other sites More sharing options...

Are the Tx the same make as the AR6255? Is the RX in the model? are there Y leads? Is the new Tx a DX6? More questions to come Quote Link to comment Share on other sites More sharing options...
Wookman Posted September 6, 2022 Author Share Posted September 6, 2022 JR DSX9 DSM2 Yes it was. It is now out of the model and still will not enter bind mode. No Y leads No More answers to come. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 6, 2022 Share Posted September 6, 2022 As a last resort Before you chuck it away, I do have a DX6i DSM2 to test it with, by return post Quote Link to comment Share on other sites More sharing options...
Wookman Posted September 6, 2022 Author Share Posted September 6, 2022 The problem is that the rx does not enter bind mode. So I doubt it will bind to anything. Though thank you for the offer. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 6, 2022 Share Posted September 6, 2022 (edited) I would be checking the line of pins for movement, as they can come away from the board, and checking for continuity with a multimeter. Check every pin individually for being loose, as easily repaired with a soldering iron. All the MINUS line are common on the top row, and easily checked for continuity. Have a servo handy and plugged into channel 1, just to hear any rotation at power up. The bind connection is a short made by the bind plug between MINUS and bottom row Signal. Check the pins in the Rx and the Bind plug. For testing on the bench I would use my trusty, safe, 4.8v nihm pack, and be sure black cable to the top, and red to the middle, go down the line of 3 pins to check for power up on each channel. As you go down the line with the battery pack plug, watch and listen for servo movement too.

Don Fry Posted September 6, 2022 Share Posted September 6, 2022 (edited) Just because a bind plug works elsewhere, don’t assume (make an ASS out of U and ME) it works in your unit. It’s an elderly unit. Things wear. Was there an abrupt end of the last installation, ie it crashed? Edited September 6, 2022 by Don Fry Last paragraph.

Nigel R Posted September 6, 2022 Share Posted September 6, 2022 As above. I have a third party bind plug that does not play with spektrum but works with the brand that is a colour. Try another bind plug? Quote Link to comment Share on other sites More sharing options...
Wookman Posted September 7, 2022 Author Share Posted September 7, 2022 No crashes involved. Variety of Spektrum bind plugs used, all of which work on other Spektrum rxs. All pins checked. Continuity across the +ve and -ve pins is good. All pins seem to be soundly connected to the board. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted September 7, 2022 Share Posted September 7, 2022 Back to the bench, Attach a servo to the Rx, and momentarily attach power to correct pin polarity. No need to connect bind plug at this stage. The servo should at least twitch! Quote Link to comment Share on other sites More sharing options...

Flying Squirrel Posted September 7, 2022 Share Posted September 7, 2022 Have you tried completing the binding process despite the lack of indication of bind mode on the RX? Quote Link to comment Share on other sites More sharing options...

Yes, predictable enough, nothing happens. 22 hours ago, Don Fry said: I note the last sentence, your opening post. The bin beckons, it's not heavy enough to enjoy re purposing as a paperweight.

Keith Billinge Posted September 18, 2022 Share Posted September 18, 2022 Take the case off and re-solder the bind pins. Maybe there's a dry joint? After that; maybe it is bin time? 1 Quote Link to comment Share on other sites More sharing options...
