Batboard

I have recently acquired an MTS1200 (no typo!!)

It looks like a MTS2000, GP1200 etc with a front facing LCD and keypad.

The model number is H01RDH9CL7AN . Its an MPT1327 trunking set.

I have checked the Batlabs archives and there is NO mention of this radio at all. I also did an internet search and there is very little mention other than under battery types/accessories where the MTS1200 is listed along with the MT2000 , MTS2000, MTX838 etc.

I have a few questions:

- which version of RSS is used to program an MTS1200? (ie is it standard "MTSX" RSS?)

- is it possible to program some conventional channels into the MTS1200 (ie similar to the GP1200 trunking set)

- is it possible to flash an MTS1200 into an MT2100? - as you can do with the trunking GP1200 radio?

Thanks

Say... do you have any pictures of this radio?

Or a copy of a codeplug you could email?

Sorry, I don't have any pictures - but it looks just like an MTS2000 or GP1200. It has a front facing LCD with a keypad. The numbers/letters on the keypad seem similar to the MTS2000 except the bottom 3 keys - which comprise a left pointing arrow , the letter "D" and the letter "S" reading left to right.

Re. codeplug - I have not yet established which RSS I need to read the codeplug. Do you know? You are very welcome to a copy once I can extract it using the correct RSS.

Any thoughts on which RSS I need to use with an MTX1200 MPT1327 trunking radio?

I tried the DOS and Windows "1200 series" RSS which is designed for the GP1200/GM1200. With both versions, the RSS came up with "wrong codeplug/model number".

There is a small difference between the model number of a GP1200 and my MTX1200 ie H01....CK... for the GP1200 and H01....CL.... for the MTX1200. So

GP1200 = H01RDH9CK7AN
MTX1200= H01RDH9CL7AN

The "CK" stands for MPT1327 public while the "CL" stands for MPT1327 private.

Thanks

Did you tried the latest GM/GP1200 Win RSS?I think this should do it.
If you don´t need the trunking mode,flash it into a MT2100!

Hi Andreas,

I used version R00.01.10 (dated 28 Nov 96) of the Windows RSS.

Which version is the latest version?

I don't need trunking mode. I have seen the modified RIB circuit diagram. I understand the difference between the "standard" and the "modified" RIB is a few switches and links (I think).

I would be grateful for a simple guide to modifying my "real" Motorola standard RIB ie like "step 1 - insert a switch between......". I don't want to make a mistake in interpreting the circuit diagram!!

Thanks.

The "modified" RIB, http://www.batlabs.com/images/rib_mod.jpg

is to correct for the mismatch of the RIB and most computers, the (stock/un moded) RIB does not match the RS232 standard.

In the later RIB Motorola added a switch and an internal 9 volt battery. But still did not correct the RS232 mismatch.

I have used the wrong term!! What I am after is the mod to convert a "real" standard RIB into a "flash" capable RIB to be used in converting a GP1200/MTS1200 into an MT2100.

What I need is some simple instructions for modding a standard RIB into a "flash" capable RIB. I might make a mistake in interpreting the flash RIB circuit diagram!!

Thanks

Will,

I haven't heard anything about the modified RIB. So my motorola RLN4008B RIB needs this modification or is that a smart rib?

Use the schematic of my Unirib!
You only have to cut some connections and connect them to a switch.
Use a 7812 with a diode into the ground terminal,for the flash voltage.
For flashing,you don´t need a SMARTRIB!

Andreas

Thanks Andreas.

Is it possible to build the switching in the "RIB to radio" wiring lead - so that I do not have to mod my original Motorola RIB? I am a bit reluctant to mess with my real expensive RIB!!

Also, the Batlabs UniRIB is version 2 (with 3 switches) while your website is version 3.1 (with 4 switches). If I want to flash a GP1200 into an MT2100 , how many switches do I actually need?

Thanks

You have to modify the rib direct!
The Unirib on Batlabs is an earlier schematic of my Unirib.
You can use the Batlabs schematic too.The latest Unirib has only a flashswitch for the Waris radios added.

I tried the lastest version of the 1200 Windows RSS (version R00.01.15) 24 Sept 1997 EVN4656B.

The RSS read the MTS1200 codeplug but at the end of the upload , the following message appeared : "Unexpected block type found" and the upload aborted. The MTS1200 had "CSQ" on the LCD display. I had to disconnect the battery to remove the "CSQ" and get the normal trunking display back.

Any thoughts?

Thanks

You are using the wrong RSS for the radio.I think you need a special RSS for this type of radio.
