Re: [E3-hacking] About connecting to the serial on the E3

If the E3 has a TTL serial port as reported here then a USB to TTL serial adapter should work fine. No need for line drivers or level adjustment, nor any need for inverters. Just connect it straight through. These USB to TTL serial are very common and cheap because they don't have the MAX232 (or

Re: [E3-hacking] About connecting to the serial on the E3

Provided the E3 and the USB device ran off isolated supplies, you might be able to get away with connecting the 5V (or whatever) on the USB adapter to the GND on the jack. That would cause the logic levels to be interpreted inverted. Note, this does not constitute advice, not responsible for any

Thanks for the advice people..  I don’t have RS232 on my PC, I only use USB to TTL on it. Do I use a headphone jack that's mono so it only has 3 connections on it, not a stereo one, any one got a pic of it so I know what to get(I know what it looks like just need to see if it a normal headphone

[E3-hacking] How does it work then the Emailer deactivated itself..?

Hi me again..  WOW I have lit this place up like a xmas tree…  Does anyone know how the Emailer works when it deactivates itself (locks itself, I came up with the word activate/deactivate because that's what its doing when it stops its features on the Emailer, deactivated non functional) I

Re: [E3-hacking] About connecting to the serial on the E3

Yes, you're right, that's clearly nonsense. Why would the E3 generate an inverted signal, anyway? If it's just the raw output from the processor (which I think it is) then it should be standard TTL levels, because it's supposed to be fed into something like a MAX232 for conversion to RS232

Re: [E3-hacking] About connecting to the serial on the E3

Could it be that I might have the RX and TX round there wrong way..? red is TX (Ring) so it connected to TX pin on CP 2102,White is RX (Tip) so it connected to RX pin on CP 2102,black is Ground (Sleeve) connected to GND pin on CP 2102..?? Spanner.. From: Nick Griffin
