V8 DIY module failure
Posted: 29 Sep 2019, 20:47
Here’s a strange one,
Took my digimac 4 from the cupboard to bind with a model and it bound perfectly but won’t work.
I know it’s bound as the green Rx light is on, then turns flashing red when tx is off.
I’m thinking, maybe the encoder needs setting up, though it was perfect last time I used it, after doing the usual method, it’s just the same, no servo movement. So out comes the handy ppm checker, unplugged the module from the pcb and plugged the checker in, Perfect ppm. So I know the encoder is working. Only other thing can the module, so as a final check I plugged one of Phil’s sc encoders into the module and no servo movement. I tried re binding to another rx and it’s just the same, so unfortunately the module has gone down. A bit odd,, as the RF side of the module works, including the low power setting
It’s a bit of a bummer really because the antenna bezel/cable is epoxied in, so will have to be removed to replace the module for a D8, which I don’t really like. Mind you I could remove the cable from the module end and leave it in situ.
There’s no reason I can think of why this has failed, bit scary
