I assembled the FRAM board today. I'll install it later after I receive the rest of the upgrade parts.


Just wondering... Did you ever install it? Does it work?

Hey, could you help? I have a CSA8000 that get stuck on the initialization screen of the 8000 series scope. I already changed the battery (used a bigger one this time, no use to change it to the same) and I had the cables connected to the MAX232 chip as you shown on your photos, plugged in with micro connector. I do have some serial to USB device (NI USB to RS232) that I connected, but I fail to capture the activity in any terminal.
Is connecting the USB-232 OK or the chip connections that you show are only UART signals? What terminal software you use to capture all that chat?
Thank you very much in advance,
Gaston

I use Putty. You can also catch it on the 2x8 0.100" on the edge of the board

I am connecting like this through a USB to serial National Instrument device, that does not show any activity.
Programming putty just show me a green cube. Something is wrong.
Could someone confirm that these connections are intended for Serial device and not a other kind, like UART?

Thank you,

Gaston
