Simrad RD68 MMSI reset

Sorry to be thick. Still can't see it.
Is ic1 the ic above 17 in this new picture?
If so there is an 'available' pair of pin holes above the 68 in the label just below the 2 resistors or maybe transistors.
Does not look much like the diagram.
Thanks in hope

I suspect you may have a later radio. Mine matched the diagram quite well. I seem to recall that mine had a transistor and capacitors in the area of the small IC. I think the IC in the diagram is the large one with the QC label on it. That would make the link under the blue or green wires. The link point was 2 square or rectangular pads on the printed circuit that were tinned, and close enough to bridge with a blob of solder.
 
Thank you for your patience fulmarjeddo.
i examined all of the area of the PCs around the wiring referred to.
There is nothing with a pair of tinned pins sticking up.
Only more let's call them resistors and the tiny copper rings seen all over the pub.
i can only assume my radio can not be changed like this.
i can send it back to Simrad but of course I'm not going to do that.

Time for a new radio (just discovered I have had the wrong MMSI for years!)
Looking at Standard Horizons GX2200E.

Going by the tinypic it will be under the blue green wires with the pcb link from the fourth pin down

Yes, this is the link that I Made and I Programmed my radio, I Have an video, i can send it to see if the menu is the same.


Best regards
 
Hello folks

I have just bought a second hand Simrad RD68 - does anybody have a copy of the pdf that Fulmarjeddo refers to with the instructions to re-program the MMSI number? Thanks in advance
 
Having now looked at the diagram and the link to the photo posted by Cuza I see that I have the same pcb as Jakeroyd. Did anybody ever work out which were the two contacts for that model?
 
I have now taken a photo of my pcb, which appears to be the same as Jakeroyd's one. I have found TWO different sets of square pads that are close to each other as indicated by the red and blue arrows. Any clues as to which ones should be sorted folks?

I have tried this with my RD68, made the link, powered up the unit, switched off the unit and removed the link and nothing has changed. The memory had not been erased and there was no option to change the MMSI.

If anyone has anymore information on this then I would be most grateful.

Best regards,

Ben
 
I have just realised that I was a bit premature removing the link!
It does work! I tried again, and now with the link still in, you can go into the MMSI settings and re-enter the number.
This process dose not do a factory reset on the unit as I was expecting, all of the stored MMSI numbers were still in the directory and the privet channels were still present.

I may try and make a short video for youtube if it helps others out....

I have the same problem!
My PCB looks like the one from jakeroyds and i don't know how to reset the mmsi.

Could anyone please help me?

Thx
 
Just had to do this on my old RD68, and I also have the version with the colourful wires that jakeroyd photographed, so the solder bridge from the PDF wasn't there. Found it on the second guess though :)

For future reference, make a bridge as shown in the photo below - the contacts were not tinned originally and I used a thin wire to connect them. After that, a small arrow appears to the right of the MMSI and pressing the softkey next to it enters the MMSI input mode.

Hi all,
Looking around for info to reset a simrad AIS (AI50), i bumped into this thread. Looks like it is not easy to access the pdf file that Fulmar Jeddo had (11 years ago, i know).
Although this is not the piece of info I do need, I'm thinking i could make the file available on my usual French forum (often visited by british/Spanish/others).
Anybody here could send me the original pdf file?
Thanks! Dimitri from Fr PS: i must be missing something, cannot find a way to MP Fulmar or anybody else.
