This page is a collection of info on the MTR2000 and possibly MTR3000 repeaters.

The MTR2000 was Motorola's mid range repeater in the 2000's, designed to do analog and sit between the two mobiles and the Quantar at the high end. It's basically a quantar-lite, as it runs the same RTOS, pSOS+ and runs on the same Microprocessor, but an integrated version of it and the DSP chip.

Software

File:Motorola MTR2000 R03.02.01.zip

File:28F800 image for MTR2000.bin

File:Mtr2000-OCR30403.CMP

Firmware

Every MTR2000 has an individual firmware package from Motorola much like the Quantar. It contains:

  • mtr_bpid-file (containing Station-ID)
  • firmware-file (i. e. ocr30403.cmp)
  • feature definition string-file (i.e. ocr30403.enc, individual file; needed to identify Serial number in Dallas DS4201 U101 on backplane)

As of now there is no known universal upgrade file for the MTR2000 as there is with the Quantar. A workaround using the OUTLAW depot software may be possible be I have not verified it. What does work is emulating the DS2401 to change the ID during programing via RSS to a known supported license key enabled upgrade.

Procedure to update via DS4201 emulation

This uses an Arduino to emulate the 1 wire serial ID of the DS4201


  1. Save your codeplug first.
  2. Ensure your MTR2000 is working 100%
  3. Use Windows XP 32 bit with a real serial port or FTDI based USB port.
  4. Install Motorola MTR2000 RSS
  5. Download the codeplug and save it! Take screenshots of every alignment data as well
  6. With a serial terminal connect at 9600 8N1 to your MTR2000
  7. Send commands (you´ll see nothing during input!):
    dorss <enter>
    get bpn <enter>
  8. write down your backplane ID number (you can also see it in RSS as station ID)
  9. Remove backplane cover:

  • U100 on back plane Dallas DS4201


  2. You can see U100 a Dallas serial IC. Be careful and desolder it, hot air is a must. You will need to re-install it later.
    3. if you dont' install this back again the repeater will have Station ID "0000000".
  3. Connect the Arduino to your PC.
    • Install Arduino IDE on PC.
    • Load MTR2000-DS2401.ino sketch into Arduino IDE and add the "OneWireHub_library.zip" in Arduino IDE as library as well
    • In MTR2000-DS2401.ino sketch you may modify the DS2401 strings: Check all 4 postions:
      0x01, 0x1C, 0x11, 0xF1, 0x08, 0x00, 0x00 (for Station ID 8F11111C); first 0x01 is family code, last two 0x00 are always 0x00
  4. Connect pin 1 of U100 IC location on PCB to a ground-pin of Arduino Uno
  5. Connect pin 2 of U100 IC location on PCB to PIN 8 of Arduino


  • DS4201 Pinout

  • hookup of Dallas Chip temporary

  • Arduino hooked up to MTR

  • Arduino with Code

DS2401 1-Wire Ground-pin: first line of 3rd connector, pin #2 from right
DS2401 1-Wire signal-pin: first line of last connector, pin #8 from left
  2. Disconnect Arduino from PC and power it from an external power supply; otherwise you'll have signal integrity problems
  3. Power the MTR2000 again; The MTR2000 should recognize the Arduino as a DS2401 and load its station ID/backplane number.
    If you want to change this, the MTR2000 must be powered power down every time for at least 15 seconds so the ram in the station forgets the loaded data from DS2401 in the controller
  4. You can check actual station ID via Putty and serial commands
    dorss
    get bpn

  • Serial Terminal Output

  2. You should see i. e. BPN = 000008F1111C
  3. Open the Load RSS and use upgrade function to push the firmware to the station.
    Ensure it's the firmware file .ocr and feature definition file .enc for Station ID 8F11111C
  4. After flashing firmware and confirming it's working you can reinstall original DS2401 again
  5. Reload your saved codeplug again and check alignment data from screenshots and that the MTR2000 is not in alarm.

  • RSS

  • happy MRT2000


  • To unlock a locked MTR2000 just temporarily until next power cycle you can use the following commands via the serial port:
    dorss
    hw_id_check_off
    reset

firmware update notes

I'm not 100% sure on this, but I belive the firmware is locked to the base station from motorola using the .enc file that comes with it. Anyone have info on this?

I took the binary image from the 28f800 and did the following to make an image that can be flashed to the station with the OUTLAW program. 

srec_cat 28F800\ image\ for\ MTR2000.bin -binary  -offset -0x4000 -o 28F800MTR2000.srec -Motorola 32 -address-length=3 -line-length=270 -data-only

This should at least replicate what's in memory. Likely can take the raw uncompressed firmware file from the update and add it into the end of it.

the .CMP file is nothing other than LZSS compressed data. Specifically it's the SZDD file format, and COMPRESS.EXE and EXPAND.EXE from DOS can expand the file directly. The header of the CMP file is "0x535A444488F02733" or "SZDD..'3" ascii, hence the SZDD name.

Docs

The MTR has a depot manual, but it's not available AFIK. IF you have one, please tell me, I will happily send you a shipping label, have it scanned professionally and send it back all at my cost. We have a partial UHF and SCM manual now below!

The part number for the Depot Manual are 68P81096E40, and 68P81096E35, VHF/UHF respectively.

It's likely the RF circuits are identical (or close enough) between the Quantar and the MTR. For Example, the Power Amp uses the same pallet amplifiers/LPF/isolators as the Quantar does.
