GP1200 problem

g8tzl2004 · Post by **g8tzl2004** » Sat Oct 08, 2005 3:36 pm

I have a GP1200 trunking handheld which I am planning to program on some conventional channels.

However, the radio is faulty. Details are as follows:

- at switch on , radio bleeps and green led comes on for 1/2 second
- then red led and continous error tone
- front LCD display NEVER lights up and displays NO characters

Any idea of possible faults?

Thanks

Code Plug checksum error (probably a fault radiofirmware)

It is required reprogramm correct code plug.

Thanks Salvik

I am about to construct a GP1200 programming lead

Will I still be able to read a corrupted codeplug with the GP1200 emitting a continuous tone and red LED - or is this not possible when the radio is in "error mode"?

I need to check the archives , but can you "create" a new codeplug with the existing RSS or do I need to find a copy of another "identical" codeplug?

Thanks

Early versions soft for GP1200 (dos rss) allow to read code plug from radio, to write code plug to radio, to make full dump memories of radio. However if code plug fault it is not necessary. It is necessary to write in radio new code plug (one remark - if there was refusal IC flash memory these measures any more will not help)

To write a new codeplug to the GP1200 , do I need to obtain a "new" codeplug , or can I just use the GP1200 DOS RSS software to make a new codeplug?

Not sure what you mean by refusal of IC flash memory???

Thanks

slavik · Post by **slavik** » Mon Oct 10, 2005 9:49 pm

GP1200 DOS RSS allows to create new code plug. In my archive is DOS RSS verstion 03.03.00.
"refusal of IC flash memory" means destruction internal structure of cells IC memory. In that case it is necessary to repair (change) IC flash memory.

I have version 03.03.00 and have located "create new codeplug" section - great!! Now need to modify old accessory plug into prog lead!!

Is it possible to "easily" replace IC flash memory OR do you need special soldering tool??

I have a MT2000 which has a duff uBGA IF chip - but impossible to replace without correct soldering tool

By the way , I have 2 spare logic boards (not sure if from MTS2000 , MT2000 , GP900 or a GP1200) - would it be possible to use a logic board from another model ??(thereby changing radio into a GP900 , MT2000 )

If so , how do I install logic board from another model into a GP1200 ?

I have just been checking the programming cables for the GP1200

I was originally thinking that I would need to put together a cable which has 6 pogo pins connected - a so called " Programming and flash cable"

However , I have just checked the Batlabs cables and the GP1200 is listed as the same cable as a GP900 / MT2000 / MTS2000 ie only need 3 pins (ie +BUS , BUSY , GND)

Will the "Batlabs" 3 pin cable be OK for "writing a new codeplug" to the GP1200 ? I will not be doing any flash programming.

Thanks

I think your radio is made of parts and the controller is wrong flashed/ programmed one.
The best way to fix the problem,is to build an Unirib and flashcable.
Program a new default codeplug (you can create it with the 2100 series DOS RSS) with MTSX-lab or Astrolab into the radio.
Get a 2100 series upgradetool and flash the firmware.
After the radio is ok,retune and program it with the 2100 series DOS RSS.
More infos about this stuff is on my homepage (in german only).

To use logic board from other radio it is possible. It is necessary to program correct Code Plug, and flash the firmware for GP1200.
Really it is better to use Unirib and flashcable. I really recommend you to visit homepage Andreas. There a lot of the interesting information.
Also see http://www.batlabs.com/gm900.html for more detailed information.

Is the GP1200 RIB to radio lead (which is on the Batlabs main site) ie only 3 pins (+BUS , BUSY , GND) OK for "basic" write codeplug to radio operation?

If I want to flash GP1200 , do I need "6 pin" lead or will "3 pin" (+BUS , BUSY , GND) still be OK??

My GP1200 is also a CENELEC radio (intrinsically safe). I checked both the RF and control boards and BOTH are CENELEC - so I think the radio is not constructed from parts - but maybe?

If I replace the GP1200 control board with an "actual" MTS2000 control board , what do I need to do to "convert" the GP1200 into an MTS2000 without flashing?

Andreas has great great site " aber ich nicht spreakensie Deutsche" !!!

If it is not required to you IS radio, and enough simple radio, can try simply install logic board from other radio.
If the band of frequencies of both radio identical most likely anything to reprogram is not necessary.
If the band different, it is necessary to program correct code plug.
The circuit of a cable for service PJ see on homepage Andreas http://www.fortunecity.de/lindenpark/me ... rtserv.gif

I have checked out Andreas' diagram for programming cable which involves connecting 6 pins onto the plug.

BUT on Batlabs main site (check RIB to Radio cables) , the GP1200 cable is listed as same cable as used with GP900 etc ie ONLY need 3 pins connected (GND , BUSY ,+BUS)

I have previously made a 3 pin GP900 cable which works great.

I could make a 6 pin GP1200 cable BUT will require making new PCB to hold pogo pins etc

I just need to know whther the Batlabs design is correct (ie 3 pins) or whether you MUST use 6 pin design for a GP1200 . Maybe 6 pin design is only required for flashing ??

Thanks

There is enough for programming 3 pin cable.
The cable 6 pin is required for flashing.

It is possible to replace an defective controller with an good one from another JEDI-model and reuse the RF-board, because the "Controller/RF-board-interface" is the same. An GP1200 with an GP1200 RF-board and MTS2000-controller becomes an MTS2000 - without flashing. But don´t forget to retune the whole "bastard". And keep in mind, that a Cenelec-RF-board will only do 1 watt of power - no matter, what kind of controller is installed.

I have just spent all day reading the Batlab archives on Jedi's!!

I also have a VHF MT2000 which has a faulty RF board - so I am working out possible mix and match options. But 1st I will simply try to create a new codeplug with the GP1200 RSS and see if I can "rescue" the existing GP1200 control board.

I have 2 "spare" control boards as well as a few UHF RF boards. I have managed to identify which models the RF boards came from (using Batlabs listing) - although they are all inter-changable anyway so model type makes no difference!!! (more or less - remembering CENELEC 1W etc)

However , I have been unable to identify which Jedi model used the following control boards :

- NCN6107B-ACL
- ETN4604A-DCV

I wonder if anybody knows?

Thanks

Keygun · Post by **Keygun** » Mon Oct 17, 2005 2:02 am

Hi.

The ETN4604A is a Cenelec controller-card for a GP900/HT1100 radio. It is a "closed architecture" controller, so forget about flashing.

The NCN6107B is a controller-card for a GP900-99 (99-channel). It has a second EEPROM on board. It is also a "closed architecture" controller.

If you are able to reanimate the GP1200, the next step you should do, is to flash it to an full feature MT2100. A original GP1200 has only 10 conventional channels and no fancy features to play with.

Thanks Keygun

Are all GP900 controllers "closed architecture" or is it only the CENELEC type?

The NCN6107B controller for the GP900-99 channel radio also has an "expansion slot" for another board (I guess) . Is this for an encryption board or something else? (no actual board is attached)

My GP1200 has a keypad and front facing LCD display. Can I use the NCN6107B controller (from the GP900-99 channel radio) with the GP1200 RF board and outer casing? I have seen GP900-99 channel radio's with "top facing" LCD's but I am not sure if a keypad/front facing LCD GP900-99 actually exists - so maybe the controller will "reject" a GP1200 keypad/front facing LCD?

I have been reading the archives on flashing a GP1200 into a MT2100. I would like to do this but will need to build a Unirib.

Thanks

Keygun · Post by **Keygun** » Mon Oct 17, 2005 8:30 am

If you are in possesion of a original Motorola RIB, it is maybe a better idea to modify it, instead of building a "Unirib". So you still have Motorola-quality and no perf-board-junk flying around on the desk.

Yes, all GP900 controllers are of the closed-architecture type. Even the 99ch-models. The small socket, you can see on the 99-board (only), is indeed for an optional encryption module.

You can bet, that the controller will reject a full keypad front. You must use a 6-digit top diplay housing and, if memory serves me right, a controller-flex with a continous rotary switch (NTN7088A). But your dead GP has such a flex already build in und will proudly deliver it.

Unfortunately (?) there is no GP900-99 with full keypad front.

I might have a go at modding my original Motorola RIB - once I find a "simple guide" rather than a circuit diagram!!

Can you use a GP900 CENELEC controller with a NON-cenelec GP900 RF board? If so , does the GP900 cenelec controller limit the non-cenelec RF board to only 1W? (compared to max of 4/5W)

Thanks

Andreas · Post by **Andreas** » Mon Oct 17, 2005 11:03 am

You can use the Unirib schematic for modifing the original Motorola RIB.
I used the original schematic and made the modifications only.

Yes,you can use the Cenelec Controller to have full power.
Change the codeplug with GP900 LAB into the right model.

Andreas

Keygun · Post by **Keygun** » Mon Oct 17, 2005 1:45 pm

The Cenelec-firmware has some "Cenelec-specific" behavior, like limited audio-power, turning off the light, when the PTT is pressed or squelch opens, aso. So the controller should be reprogrammed as a full-power radio. If you have no access to the right LABtool to do this (the regular RSS will not do it), i would suggest to use an standard-controller.

Modifying of the standard RIB is no big deal. Only some additional wires and a toggle switch. Thats all.

Well , I have learnt a valuable lesson - if a radio does not work , DO NOT believe what it says on the front of the radio!!!

I was about to get out the DOS laptop to have a go at writing a new codeplug to the GP1200 when I decided to open up the radio and actually check the different boards.

Andreas was right !!!! This is a "bastard" radio made up of bits!!!

The boards are as follows:

NUE7235C - RF board
NTN7809B - Controller board
NTN7676B - keypad/display board
NTN7087A - control flex
GP1200 Cenelec front case

I have searched Batlabs/rest of internet and believe boards are as follows:

NUE7235C - CENELEC UHF RF board
NTN7809B - GP900 16 channel controller (NOT cenelec?)
NTN7676B - Cenelec MTS2010/MTS2013 15 key front LCD display???????
NTN7087A - GP900 control flex strip/16 position rotary??????

I would be grateful if somebody could check above part numbers.

The control flex strip (NTN7087A) has a 16 position rotary AS WELL as a 2 position "outer shaft" rotary (like on my MT2000) . I am NOT aware that any GP900 has the 2 position "outer shaft" rotary BUT maybe it is a standard feature and just not used on the GP900?

Can I actually use the 15 Keypad front LCD display (MTS2010???/NTN7676B) with a GP900 controller? ( I have only ever seen keypad but NO LCD display GP900's)

Any other thoughts? I have a MT2000 (48 channel top LCD display) with a faulty VHF RF board. Maybe I could turn this into a 160 channel front display keypad UHF radio?

Thanks

It is also a good practice not to trust a working (especially ebay) radio, unless it is readable and programmable with the right RSS and completely tested on a service monitor.

The right control flex for a GP900-99 should have an continous (not a 16 positions switch) rotary switch (keep in mind, that 99 channels needs to be switched) with "outer shaft" concentric switch. This one is for encrytion on/off. You will find this concentric switch only on GP900-99 radios and another special model, called GP900-11b.

Since there is no GP900, even GP900-99, which can handle a full keypad front, you are out in the cold with this combination of parts.

Yes, it is possible to reprogramm a MT2100 controller, in order to accept a full keypad front, but you need a special LAB-RSS for this purpose. The regular RSS will not allow you to load an B7 file into an B4 controller. But the work would pay off: A nice radio with 250 channels and a lot of useful features.

It seems your search was successful:

NTN7676B - MTS2000/MT2000/GP1200/PTX1200 full keypad front, CENELEC
NTN7087A - MTS2000/MT2000 control flex 16 position rotary + concentric switch

Can the NTN7087A control flex be used with either a GP1200 OR 16 channel GP900? (or is it restricted to MTS2000/MT2000)

I guess I could use the MT2000 controller from my duff VHF 48 channel MT2000 to "build" a 160 channel keypad front display UHF radio

If the MT2000 controller is a NON cenelec , will it accept a cenelec full keypad/LCD front? Will I need to change the controller into a "cenelec" controller using LAB? Will this mean that I CANNOT then use a 4W full power UHF RF board because the "cenelec" controller will reject it?

Thanks

Keygun · Post by **Keygun** » Tue Oct 18, 2005 12:15 pm

A MT-controller can do 250 channels. Not bad, huh? Standard full-keypad MTS are capable of only 160 channels.

No, the NTN7087A controller-flex should be used for MT and MTS - no GP900 and no GP900-99. A NTN7088A would be more fancy, because you don`t have the 16 channel-limitation for each zone anymore.

The electronics of a Cenelec-front is slightly different from the standard model, but the interface to the controller is the same. So it should work. But first, you have to tell the controller, that he is now a UHF-radio with a full keypad front. Otherwise he will reject the keypad front.

I have decided to do a "2 step" mod of my VHF 48 channel top LCD MT2000 (which has a duff VHF RF board).

- replace VHF RF board with UHF 4W RF board - then use as a 48 channel UHF radio for a few days!! , then

- replace 48 channel top LCD display with 160/250 channel "GP1200 cenelec" front facing LCD keypad front

So , I will need to locate 2 codeplugs
- UHF 48 channel top LCD display codeplug
- UHF 160 channel front LCD display keypad codeplug

Once I have the codeplugs , can I use "standard" NON- LAB MTSX RSS to write UHF 48 channel codeplug to "VHF" 48 channel MT2000?

If I then want to "expand" the MT2000 into a UHF 160/250 channel front LCD keypad radio , do I now need to use MTSX LAB RSS to write codeplug to radio?

Thanks

Keygun · Post by **Keygun** » Wed Oct 19, 2005 1:31 am

Forget MTSX-LAB and use Wookie-LAB or the very special Skywalker Engineering Tool (rather hard to find). They are still (some of) the best an most versatile tools for european MT-radios with Select 5 signalling. You can create default-files with the mentioned tools, so you don`t have to hunt for files, which are readable with your version of MTSX-LAB. This always sucks.

You will need a Lab-Tool, to forcefeed the different file into the radios controller. A regular RSS will always complain about the model-mismatch and aborts writing. Later tuning and changing of the codeplug (except Serialnumber and Modelnumber) can be done with the regular RSS (2000 & 2100 Series Select 5 Radio Service Software).

Even with the small display cover installed, you can have 250 channels on your radio. This is a little different to the MTS2000, which only can do 48ch on the small model. But don`t forget to use a NTN7088A controller-flex with continous rotary. It is also nice to have it on a full keypad radio.

This is getting complicated !!!!

It serves me right for experimenting with "GP1200 bastard" and MT2000 at the same time!!!!

I don't have NTN7088A continuous rotary only NTN7087A 16 channel rotary . Does this mean that I cannot get 160/250 channels with "GP1200/MTS2000 keypad front display"??

My MT2000 is a USA made radio.

I understand that GP1200 , GP900 and MT2100 were European made radio's

Can I use Wookie LAB with a USA made MT2000?

Can I used MT2100 RSS with a USA made MT2000?

Can I create a codeplug for USA made MT2000 with Wookie Lab and then use codeplug with USA MTSX LAB RSS?

Keygun · Post by **Keygun** » Wed Oct 19, 2005 2:48 pm

Is your radio an MTS or an MT2000? Does it have Select5 signalling? What is the exact modelnumber of the radio?

I your radio is a real US MT2000 (which has 60% MT and 40% MTS genes), it should be no problem to forcefeed an "european" file into the controller, using "Wookie LAB". But after that, you need to change the radios firmware by flashing it with the "Skywalker Upgrade Tool". Then it is possible to programm it with the regular european MT RSS.

If your radio is a MTS, things are really getting a little complicating. First you have to check the date of manufacture of the radio, to ensure it is not a newer model, which don`t like treatments with a Labtool. Use of a Labtool on a newer MTS will end up with a dead radio. TOOLPROOFING is the word.....

Older ones - if memory serves me right, radios made prior September 1994 - don`t have this f...... "feature" in its firmware.

MT2000 is a real US MT2000 . I am NOT sure if it's a select 5 radio - maybe its MDC??

Model number is H01KDD9AA4AN

Type KDHA

I have already been able to read/write to radio using MTSX LAB (version R02.00.01)

The VHF RF board is faulty (understood to be problem with uBGA IF chip - strange RX problem - 5khz off freq , strange noises , sometimes deaf ; TX perfect)

I want to 1st change VHF board with spare UHF 4W board and keep existing top LCD and 48 channels

Then I want to experiment with attaching "GP1200 cenelec" keypad LCD front panel to create 160/250 channel radio?

I think I need to locate:

- UHF 48 channel top LCD A4 MT2000 codeplug
- UHF 160 channel front LCD A7 MT2000 codeplug

I don't want to start "flashing" yet - will need to build new programming lead with 6 pogo pins and modify RIB - so prefere to keep USA MT2000 as a "MT2000" rather than a "MT2100" (this can be another project or maybe I will find a real MT2100 controller )

I have just been experimenting with Wookie which runs in Windows (not DOS) - I was not able to figure out how to "create a codeplug" but I am not sure whether a codeplug created in Wookie will work with USA MSTX LAB?

Toolproof is not an issue on the MTS2000 if you want to flash it into a
MT2100!
Older MT2000 are mostly closed architecture radios and could not be flashed!
You can use Wookie Mobius Lab on your radios,but it is not allways the best choice,because the RSS is an old beta version an have some problems.
Create a default codeplug with 2100 series DOS RSS and program it with
MTSX-LAB (read/write with no pack/unpack) into the radio.
After this,you can flash the radio with the 2100 series upgradetool.

I have a USA made MT2000.

I thought that European made radio's were MT2100 as well as GP900 and GP1200?

Is there a European made MT2000 ???? (ie NOT the MT2100)

If there is a European made MT2000 , is it "different" from USA made MT2000? ie maybe USA MT2000 is "open architecture" while European MT2000 is "closed" (like GP900 controller)

Which version of MTSX LAB do you use ie Version R02.00.01 OR Version R03.00.02??

Keygun · Post by **Keygun** » Thu Oct 20, 2005 12:05 pm

It seems, everybody has his own "secret" for flashing the radios

.

I never had problems with Wookie. The fact, that it don`t recognize some radio models, is not exactly a bug. Those models are not present in his model library, so Wookie simply don`t know them. We should not forget, that some of the nicest Lab-Toys from M, are "only" Beta-versions.

Wookie or MTSX-Lab is only the first step of the "flashing" process. Its job is only to forcefeed the "wrong" codeplug into the target radio, without complaining about wrong bandsplits, modelnumbers or serialnumers. Thats all.

If your radio can do MDC, you can be shure that it is an US model. US models have a featureset, which is different from the european radios. An US MT is closer related to MTS, than to the european MT. You can see it as a MTS without trunking cabability. Maybe this brings some clarification.

I have been looking at Wookie again.

I have found the Wookie codeplug library which does contain the correct UHF MT2000 codeplug. I tried copying correct codeplug into MTXS LAB but MTXS LAB would not read - "not a DOS file"message

Can I use Wookie to program a USA made MT2000?

With Wookie , can I use Windows XP and a P4 to program my MT2000? (or does it require really slow machine and old Windows?)

Can you "force" a UHF MT2000 codeplug into a VHF MT2000 using Wookie without needing to do any flashing? ie keeping radio controller as a USA MT2000 and not converting into a European MT2100?

Thanks

Wookie Mobius Lab is only for 2100 series radios!!!
For MT2000 you have to u use the MTSX RSS/CPS.
MTSX-LAB won´t read Wookie codeplugs.You have to create a codeplug with the 2100 series DOS RSS.
If you want to clone Mt2000 codeplugs,use MTSX-LAB.

To Keygun:
Do you ever programmed a MC2100 with Wookie Mobius LAB ?
Sometimes the radio will not work anymore,gives you an error,andyou have to fix it by program a new default codeplug with the 2100 series
lab upgradetool.
Wookie Mobius Lab will not allow you to set the frontend at MC2100 radios!

Windows XP and a 200Mhz processor is not a good idea on this rather old softwares. A very good and reliable platform is a 386DX or SX processor with 25Mhz clockspeed. On some radios even 25Mhz is too fast, so it is not bad, if the computer allows to turn of "Turbo". An exception are the new CPS, of course.

If you forcefeeding a file made by Wookie, your radio will always become a european version (with Select5). So if you really want to have an european radio (which is not bad at all), flashing after forcefeeding is necessary, because the original-firmware is not able to "understand" the new file.

If you want an unchanged US radio, simply change the file from VHF to UHF and programm it back or load an archive file into MTSX-Lab, which exactly matches your hardware, and program the radio. You don`t need to flash anything. Its a simple reprogramming with a software, which don`t care about bandsplits.

I never use a Labtool for tuning a radio. I always use the standard RSS for tuning and further reprogramming.

Thanks Keygun/Andreas

OK, I will keep "USA made" MT2000 as a USA radio and NOT create a "European" MT2100.

I need to create a UHF 403-470 MHz codeplug for a VHF 48 channel A4 top LCD 16 position rotary MT2000 - model number H01KDD9AA4AN

Using MTSX-LAB version R03.00.02 , the "create codeplug" does NOT work . I think its been hacked or something.

Can I use MT2100 RSS to create a UHF codeplug for a USA made MT2000 ??? I already have a "USA" VHF codeplug , of course , downloaded from the MT2000.

Thanks

No, you can`t use a MT2100-file for a US MT2000, if you want to stay with a US MT.

It is possible to change the VHF file to UHF by altering all band related parameters of the codeplug. But i recommend this only to experienced users which are completely familiar with the Labtool. Not to mention, that you should save your original-file to disk, before start "playing" with the radio.

Thanks Keygun

Is it possible to use Hex Workshop to increase the upper limit of the VHF codeplug from 175MHz to 470MHz?

Has anybody got a "real" UHF codeplug (see above for model number etc) for a USA made MT2000 dated around 1993/94?

Thanks

No, you don´t need any hexediting. Since MTSX LAB is a Labtool, it allows you to change all bandsplit-dependent parameters of the codeplug. But it is also very easy to screw up a radio with an improper modified codeplug. I think, it is a better idea and more shure way to look for an "ready-to-use" codeplug, which can be read with your version of MTSX LAB. It should be no problem to find one here at the BB. Unfortunately i have none that suit your need. I´m playing mostly with MTS or MT2100.

Thanks for all the very helpful feedback - I will post a separated request for correct codeplug.

Cheers
