Question

Hello colleagues! I have to talk with the Motorola Gm 350, for this purpose I am asking my esteemed colleagues for some RIB diagram and working soft, I know that the topic has already been discussed more than once because I looked at the posts, but not everything is probably up to date, I am...

RIB on transistors - works, checked: And soft ...

Hello Pawel!

And I have a rib made according to:
http://www.batlabs.com/2wayrib.html

I programmed the GM350 with it. Soft will also be found, so call me priv, I will lend it to you because there is no point in making a rib for one radio

73!

I went easy ... And the difference is not visible and is in DB9

Paweł Sq6dxp · Answer

Thanks a lot for your help! Everything would be useful, if I gave a plame, I would show up to Jacek for a loan. by the way, best regards!

yes2mike · Answer

It should flash ... I think I once attacked the motorole GP1200 with the programmer from Alcatel 9226HX, just on MAX232.

Paweł Sq6dxp · Answer

This is how I see that the Rib to which Jacek gave the link in the Max 232 part is almost identical to mine to fth, it is tempting to make a rehearsal in a free moment, but maybe it's wrong and it won't go, you can always do it then " neat "on transistors, which will fit in the plug and will be ok. Thanks a lot for your help.
There is one more "painful" topic, I am a "happy" owner of a Kenwood Tk 762G which I have to reprogram and I have a soft but Rib, unfortunately, if someone had at least a description of anything, it would be great

Hello, I have made it on 7 transistors and this on max232 and they work without any difference

Paweł Sq6dxp · Answer

It can take a look at your resources, maybe that you have something to do with Kenwood, and it would be useful to me, there is a peasant in Opole who has this Rib for Tk762G, but he is unfriendly, greetings.

RTX-Service · Answer

it's all I have to kenwoodów related to programmers

Paweł Sq6dxp · Answer

Thanks to you, good man, I will try to figure something out of it and I think that something will fit.

RTX-Service · Answer

Not at all poor, I have something for free, I do not regret the other, good luck in constructing, I think that the one on xax232 should fit, as I know life, these opto elements are not needed there, but also harm

yes2mike · Answer

Then you went, my friend

Paweł Sq6dxp · Answer

I tried to play with this Kenwood, but so far something does not work out, I do not like the microphone socket connections where, according to the description of the adapter on the socket, there is a mass on the radio for me is 12v, I checked twice to rule out the possibility that I was wrong, but unfortunately not, I have to find a description of the microphone socket somewhere, I have no idea how to put it into service mode to read the radio, it promises to be a long way.

original RIB schematics look for if you want on Cqham.ru website Greetings

Paweł Sq6dxp · Answer

Hello, I have solved the problem, the system works on Max 232 and works fine, best regards.

yes2mike · Answer

Noooo Simple solutions are extremely effective I have to check if the MAX232 system actually works with GP series motorcycles

Paweł Sq6dxp · Answer

I will not tell you to the Motorola GP series, but yesterday I visited the emergency department and they have the GM 300 series motorola and some Yaesu VX kenwoods, etc., we looked inside the programmers, the newer ones, already made in smd, that fit in the plugs, but all based on Max 232, a programmer ended with a socket and a different cable with a properly seasoned RJ plug for each type of radio, I did not ask about the Motorola GP because from what I saw they had manual Yaesu, but if I will next time I will throw it and this topic may find something. Regards.

RTX-Service · Answer

on a max of 232 SN 7407 there was once an interface scheme for gp300, I tested the gm 350 and it was flawless, from what I remember when I was flown on the pages, these programmers were recommended for GP, it was all based on this diagram above, included in this post, but for example Mc2100 I was not able to erush to the maximum, I also want to make two programmers, especially that their cost is not high

yes2mike · Answer

Gm and Gp 300, 350 etc. have only two wires: BUS and GND ... I use RIB on transistors for such motorcycles ;)

transistor ones fit this type of equipment (two linines), but I am struggling with BUS +, BUS- and GND ... The voltage seems to be the same.

A. The exception is GP640 (I have not checked on another one) - I don't want to talk to this RIB ... But I will

Paweł Sq6dxp · Answer

Hello, in connection with the need to close the topic, thank you all for your help, I used a programmer based on max232 every day for programming yaesu fth, a properly prepared RJ plug and everything flashes as it should, greetings!
