Firmware recovery on WS-6-MINI

[Ellyan]

Hello there,

Fisrt of all thank you for your amazing products.
I am a network provider for temporary events such as music festivals, fashion shows etc...

I have over 20 WS-6-mini and 5 WS-12-250-DC.

2 of my MINI's were bricked during update because of power losses (my fault)
The warranty is void on those because i had to take them out of thier case to install them in weatherproof cases.

I am willing to try firmware recovery and have acces to the header so if you would be willing to give me the pinout and voltage level of the UART/serial port I could revive those 2.

Thank you in advance

HDR5 is the header, pin 1 is Tx, 2 is GND, 3 is Rx (from the board's perspective). I use an FTDI TTL-232R-3V3-WE with a 1x3 pin header soldered on, pin 1 yellow, 2 black, 3 orange. Port settings are 115200, 8,n,1. Pin 1 on the board is indicated by a dot, and is the pin closest to the ports.

Careful you don't tie either active pin to ground; While the on-board UART is protected in this instance, the cable UART can be damaged if you do.

Thank you very much

I will try it these days

In an in warranty situation would would you guys prefer we do if we have a snag with upgrading a ws-6?

In our instance we're sure it wasn't a power related snag, just the switch never came back after.

The WS-6-MINI requires a special cable to console into it
Sadly RMA

If it less than a year old we do for free as courtesy and $25 if more than a year old.

Alright, I guess we start doing bulk RMA/repair shipments now?

But on the bright side, I've lost count how many of your switches we have deployed
