I'm confident enough that its not going to be a problem that I plan to fabricate a RJ12-DB9 cable and give it a whirl.

Hi,















I would like to update the firmware on my PowerFlarm Butterfly display, but







I'm a bit confused by the directions for fabricating the required update







cable. Note that I'm an Electrical Engineer with over 40 years of bench







design and fabrication experience, so if I'm confused, I expect others are







as well.















The instructions provide a pinout for the display-end connector, with notes







as to where each pin should go on the PC end. However, the PC-end







connector isn't specified - is it supposed to be a DB9 serial connector?







If so, you must know that DB9 serial connectors aren't widely available on







modern PC's; I have 6 PCs in my home office, and not one of them has a DB9







serial connector. When I need serial port connectivity, I use a popular







USB-serial adapter. Will your display update properly when using such an







adapter?















Your specification calls for pin 5 of the RJ-12 connector to be tied to







+3.3VDC, but this isn't a common voltage for serial communications. What







happens if this line is connected to +5 or even +12 VDC?















Regards,















Frank











Frank,







Please post an update if all goes well. I prefer not to tune my device for maximum smoke if there is some other brave soul willing to go first!







tks

You guys do know about this, yes? (From external display manual)



"Updates

Update through PowerFLARM®

After Q4/2012 it will be possible to update the displays through any PowerFLARM® unit

directly without the need for a special cable."

Evan,

Just saw this myself in the Butterfly manual - wonder why they didn't mention this in the response to my email?
