Hantek 2c42 nao liga apois interrup??o da atualiza?ao do firmware Socorro

elison

Olá, tenho um 2c42 e no início da atualiza??o do firmware meu PC travou e reiniciei. O osciloscópio agora n?o liga, quando eu o conecto ao PC o bot?o liga / desliga permanece ligado e se eu remover as baterias e reconectar o bot?o liga / desliga ele fica piscando. Existe uma maneira de recuperar o osciloscópio ?? Ajuda por favor !!

Hello, I have a 2c42 and at the beginning of the firmware update my PC crashed and restarted.
The oscilloscope now does not turn on, when I connect it to the PC the on / off button remains on and if I remove the batteries and reconnect the on / off button it is flashing.
Is there a way to recover the oscilloscope ?? I was also reading some posts that use a usb adapter module ttl rs232 pl2303 hx how do I do this step by step and what files do I use? I took a look at this dolink video https://www.youtube.com/watch?v=-uF2fdVxx1E
Help please !!

I got the files but I have doubts
in arm1 says that
Does the VCC not need to be connected? because? in the forum they said it only worked with the connected VCC and the RX AND TX SHOULD BE NORMAL OR REVERSE CONNECTED?

I have sent an email to you, please check.

I received your email, but I have the following questions:in arm1 says thatDoes the VCC not need to be connected? Why? in the forum they said it only worked with the connected VCC.and about the RX AND TX MUST BE NORMAL OR REVERSE CONNECTEDhttps://produto.mercadolivre.com.br/MLB-1140989965-pl2303hx-pl2303-hx-conversor-usb-cabo-p-ttl-rs232-arduino-_JM?quantity=1

CHECK THE LEVELS TTL-ONLY 3V3!!! NOT 5V!!! connection Rx, Tx-reverse. Power- USB  cable from PC.

how do i check the ttl level? to measure by the multimeter? because the adapter is this link ai I don't know for sure because it says that it has 3.3v and 5v output and also says ttl 3.3v level

a big doubt I am about the adapter: R $ 3.22 5% OFF | 1pcs PL2303 USB To RS232 TTL Converter Adapter Module
https://a.aliexpress.com/_mLev2h9

it has 5 output pins 5v and 3.3v Tx and Rx and Gnd but what would be the ttl level? can I use this adapter there from the link taking the 3.3v adapter and put in the oscilloscope vcc
but the final doubt is about the tx and rx have some max tension that these can withstand? will be that the tx and rx of that adapter there is compatible with the oscilloscope? in the description it says that it is ttl 3.3v and 5v levels beste if this adapter has automatic tx and dx voltage? can I use this adapter on the oscilloscope 2c42?

Segui os passos do arm1 que ame passou e gra?as a Deus deu tudo certo e osciloscopio voltou a ligar e funcionar normalmente
