I recently sold my boat complete with AIS unit. The boat has been registered on the Portuguese registry (was SSR). A new radio callsign and MMSI number were issued to the vessel as apparently part of the MMSI is country specific. Changing the Callsign is no problem but we thought we'd have problems with the MMSI in the radio and the AIS unit.
ICOM radio has been sent away to Lisbon be reprogrammed with the new MMSI.
Matsutech were more forthcoming. The new owner emailed China asking if the HP-33A could be reprogrammed.
They answered within 15 mins.
See attached pdf. but basically you just scroll up to the mmsi number as you would expect, but then you have to keep scrolling up to get to the edit function.

These are their words in the attached file:-
"In this screen , press the cursorpad.



Press and hold the up , and the cursor will keep up and up , (About 6 times, the cursor will stop, and you can edit MMSI)

until the cursor stop at the column MMSI , then you can edit it again."

I didn't actually do it but the new owner said it was simple to do.

I have a Matsutec hp528-a AIS I want to edit my MMSI, I sent an email to the manufacturer and they responded giving me the same instructions but I have not been able to reset it, the only thing that allows me to edit is the approach point and the approach time, I returned it to send an email but they don't respond. Am I doing something wrong? Can you help me? Thank you
 
Interesting ...

I know that on most sets VHF / Plotters with AIS .. that as long as you have not confirmed MMSI to the unit ... you can edit - but according to standard (which actually some did not adhere to in early days) - once entered and confirmed - should require Service Agent to change.

Looking at the PDF - that illustration appears to be BEFORE MMSI confirmed / entered into machine.

The mmsi had been entered and confirmed for several years and the new owner changed it using this procedure. i can't say more than that as I didn't actually see him do it. I'm sure it worked though because he actually rang me to let me know how he was getting on with the boat and this was part of the conversation.

After posting ... I had a look at the Onwa I have ... close relation to the Matsutec. OK - mines the budget KP39A unit ... but same AIS as the higher end units.

Power on
Disclaimer Dialogue box
Press Menu and ESC together takes to MMSI / AIS GPS data input screen.

I could change all details ..... incl MMSI.

Been looking at Matsutec 33 manual and it says cannot be changed ... so this is interesting thread ....

Setting Name; Setting Vessel Type - Matsutec HP-33A Operator's Manual [Page 38]

Honest - I believe you - I've seen it changed on various gear by use of a shunt / solder two points ... all sorts .....
 
The possibility to change MMSI in an AIS Plotter unit may be because unlike a VHF MMSI unit - it does not have emergency RED button to send data over the DSC channel.
Wrong info for a target showing on anothers display is less critical than sending out on a DSC Distress ??

That's incorrect.
 
I am really interested in this because as I investigated my own Onwa unit - MMSI and Cal Sign can be changed easily. There is a level of security that User can Password enable to block access to the Data Setup page. This security set-up is not listed in the manual.

I would like to know if the Matsutec is similar ? Maybe "Anders88" has come up against similar in his Matsutec unit ?? I assume that "Greeny" never enabled any security - if any is possible with Matustec ??

Why would I like to know ? Lets say as a 'prompt' to get to full info for others .....

Considering the double ? in my post - it was set as a query and possibility.

Paul - Given your outstanding knowledge then why not post correct info instead of smarmy comment ??

Here we go with another Romper Room thread.

You made two statements, the ??s followed the second.

It is incorrect to say "The possibility to change MMSI in an AIS Plotter unit may be because unlike a VHF MMSI unit - it does not have emergency RED button to send data over the DSC channel. "

You cannot change the MMSI on even a stand alone (no display) AIS without returning it to a dealer, or at least that's how it should be if regs are followed.
 
Romper Room ..... love it.

Just to try and pass some elementary English Language into Pauls Romper Room.

"It is incorrect to say "The possibility to change MMSI in an AIS Plotter unit may be because unlike a VHF MMSI unit - it does not have emergency RED button to send data over the DSC channel. "

May be is not a statement of actual but a possible - open to being questioned or shown to be right / wrong. Your quote indicates your misunderstanding of that concept.

"You cannot change the MMSI on even a stand alone (no display) AIS without returning it to a dealer, or at least that's how it should be if regs are followed. "

At least you added the last bit .... as clearly from not only my check today and OP's post - there are Plotters with AIS that can be changed. That also brings us to ..... OP was referring to a Plotter with AIS .... not a stand-alone AIS unit.

I wonder if the type of unit may cause a grey area in the regs ..... a Transponder which most AIS in the Yottie world are not could be reason for locking the MMSI .... while a Transceiver may allow some leeway .............. AGAIN THE USE OF WORD MAY ....

Still interested to know why it can be done on some but not others ....

Only on very early firmware.

when I purchase my new hp-33a it came programmed with the MMSI no. of a Chinese tanker! At the time situated in the south China Sea..
initially I was a bit worried as I though it would have to go back, but a factory reset sorted it...

my question - is it worth updating the firmware as I must have an early version?

Hi Anders,
this procedure is for Matsutec HP 33 A.
You do not need to press the Power button.
You need to go to the page shown in the attached document where the mmsi number is listed.
Then use the "up" ^ button to select the mmsi number.
Then press the "up" ^ button 6 times. It looks like nothing is happening but after 6 times the mmsi is ready to be changed.
I do not know if this will work on the HP 528 model but it is worth trying.
I hope this helps.
 
the attachment that the manufacturer sent me says that it is the same process for HP 33A. try pressing the cursor ^ 6 times but I can't position where the mmsi is placed. The option that I need to try is pressing the power button and the cursor ^ 6 times
