G90 firmware upgrade failed.

The PC side seemed to be OK, but the PC failed to establish the initial handshake communication with the PJ: Always in hour-glass waiting mode until the connection timed out after exceeded the maximum # of retires. I tried just about everything I could think of and nothings go:

> Custom made the 9-pin cable & verified all pin connections end-to-end.
(1-1, 2x3 cross, 5-5, 4x6 cross, 7x8 cross, 9-9.)
> Also tried the other cross cables configuration as documented, but still no go.
> Tired 3 PC's: 2 XP-laptops, 1 Win98 desktop with verified good COM ports.
> Tried all 3 different baud rates (properly set on both PJ & PC).

> Tried both PJ's Device Index 00 & 01.
> Tried both PJ's Standby & Power-on modes.
> Tried both PJ's RS232C & 422A 9-pin inputs, just in case.

> Reset the PJ to Factory default (Service, Factory & Initial data).

Did anyone found anything else that I haven't tried?

The last resort would be to buy a Dallas chip with the software already upgrade in it and hope that it would work, but I will loose the serial # and hours used of the lens (not a big deal, really).

Thanks much.

Hi Graig,

I did try a regular null modem cable and it didn't work.

If the YA board was where the FW was kept, I hoped that some member with a G90 who lives nearby Orange County, CA may be be willing to host this YA board FW upgrade. I lived in Lake Forest, near El Toro/Laguna area. Will any member around here or in LA/SD areas be willing to do me this favor, or for a fee if needed to be? Even though I can live and get by with the original firmware release, some of the software bugs were quite a bit annoying without the fixes.

If no one felt comfortable in doing this, Craigr, will you be willing to do the upgrade for me if I send you the YA board, for a fee too, of course? You can PM me about this.

Thank you for your super quick reply.

I meant, sending me a private email, not a PM, sorry.

Thanks.

I guessed that I confused between PM which stood for Private msg but it also can stand for Public msg!

It turned out that my G90 was one of the earlier production unit and the firmware upgrade failed may be because of this. Craig put the YA board in his PJ and the upgrade went thru. I am now on the new firmware! Thanks Graig.
