Default Can i use any USB to Serial converter to update BeastX?

I've tried other brand Silicon Lab serial converter, same CP210x USB to UART Bridge as BeastX converter, but i can't seem to get the updater to recognize it.

I have too many USB to Serial converter and i try not to buy another one.

I connect the 2 outer most pin. One is the Gnd and the other is the signal (i tried to use Tx and then Rx, both didn't connect). I leave the center pin empty as i though it suppose to be power.

Yes, i did power my BeastX with separate battery from the ESC, delivering 6V.

Did u do anything wrong in the connection?

I should say that I tried the Futaba CIU-2 and the Castle Creation link and they didn't work .
That's all, sorry.

Ciao.

thanks for the reply.

I think they may have integrate/introduce the Silicon Labs UART converter with ID number and the update software to recognize it before connecting.

No, it has nothing to do with any ID numbers or software issues...

The USB2SYS Interface uses a one-wire serial connection, so on both sides the Rx- and Tx-Data line are connected using a diode...

Probably neither the CIU-2 nor the Caste-Creation link have this circuit.

The SYS-Connector of the MB has the same pin allocation as a servo (GND, +, data), so you can connect a buffer-battery to this port.

Thanks SteffenJ for your comments. Appreciate it.

Does the converter make use of "DTR" signal from the silicon lab chips and combine it with Rx and Tx, with a couple of diode & zener? Or just make use of Tx and Rx with couple of diodes?

It's only from Tx trough the diode, and then together with Rx, cause it's not allowed to pass signals from one side Tx (eg. MB) to the other Tx (eg. USB).

Futaba CIU-2, Castle Link, Spartan Flash Link, BeastX USB2SYS, I hope they could agree to a single standard someday...

hi nizze

I don't know if this might help. Your thread got me curious to try my usb connectors. To see if the updater would at least recognize it.

Castle Link didn't work. CSM didn't work. Spartan didn't work. But of course, I do have BeastX that works. Then just to mess with it, I plug the Zoom USB dial up modem. And the updater actually recognized it, COM5.

What if you try some of the USB device you never use for a while. To put something together that might work.

It will be much easier if someone opens the BeastX usb interface and posts some pictures here. I believe it is just a USB-to-TTL convertor with some tricks in the data lines.

Looks like a UART to 1-Wire.

Tried those method with a single forward diode (1N4148) link from Silicon Lab chip Tx line (also tried Rx line) and combine them together then to the BeastX signal line, doesn't seem to work. See my schematic on earlier post.
There may be some other components.

Is the Updater recognizing the without connecting the MB. Just asking, Because the updater on mine recognize the com on USB modem.

Same with the BX USBSYS. Updater recognize it too without being plugged to MB.

I bet you they are using a TTL switch to isolate the Rx/Tx lines while the local Tx is operating to avoid listening to its own Tx line.
