PROGRAMMING SOFTWARE

SMP 4001 V4.30 17/7/91 73.2K

Use with the SMP4001 Programming Unit. This connects to SPX 2000 series radios via an eight pin header on the radio's PCB just below the antenna. SMX 4000 series radios are programmed by removing the EEPROMs from the radio and pluging them into the Programming Unit.

Programs SPX 2000 series (SL70) and SMX 4000 series (PM150) radios.

SPX 2000 series radios may have A or B version internal software. Radios with A version software have a serial number less than 910602001 (VHF) or less than 910501923 (UHF).

Use with Programming Adaptor PCB which connects to SPX 2000 series radios via a six pin Hirose socket on the top panel of the radio.

Programs SPX 2000 series (SL70)

SPX 2000 series may have B or C version internal software.

SMP 4004C V2.19 26/8/97 162K

The designation SMP4004C refers to hardware as well as software. It is possible that the hardware element is a PC. SMP4004C is used with an SPA-2000C programmer, to which it is connected using a ribbon cable. Connection from the SPA-2000C programmer to an SPX 2000 series radio is via a round Program Adaptor cable with 6 pin Hirose plugs on both ends. This cable can also be used for the cloning of radios, so it is safe to assume that it has TX and RX crossed. Possibly there are other Program Adaptor Cables for radios not having a six pin socket.

The above information was extracted from the service manual for an SPX 2000 series radio dated 12/94. The description however does not seem to tie up with V2.19 software. V2.19 software recognises the Programming Adaptor PCB and can probably be used to program SPX 2000 series and SL-70 radios.

Programs SPX 2000 series, SMX 2000 series, SMX 4000 series, SL-70WVM, SL70WUC, SP120, SP130 and SP140 radios.

SPX2000 models with 10 channels have version B software. SPX2000 models with 4 or 16 channels have version C software.

Information from Service Manual for an SPX 2000 series radio and by checking the software.

SMP 4004C V2.20 28/12/99 169K

The above information was extracted from the service manual for an SPX 2000 series radio dated 12/94. The description however does not seem to tie up with V2.20 software. V2.20 software recognises the Programming Adaptor PCB and can probably be used to program SPX 2000 series and SL-70 radios.

Programs SPX 2000 series, SMX 2000 series, SMX 4000 series, SL-70WVM, SL70WUC, SP120, SP130 and SP140 radios.

SPX2000 models with 10 channels have version B software. SPX2000 models with 4 or 16 channels have version C software.

SMP4005 V2.01 27/5/93 77.6K

Use with Programming Adaptor PCB, which connects to the radios via a six pin Hirose socket on the top panel of the radio. The Programming Adaptor PCB may require modifying by connecting a 10MFD 16VW capacitor in series with the yellow lead going to PL1-4.

Programs SL70E and SL500 radios.

PROGRAMMING INTERFACES

MAXON SMP4001 PROGRAMMING KIT

The Maxon SMP4001 Programming Kit consists of the following:-

Programming Box. (Basically an EEPROM Programmer).

Serial Transmission Link. (A cable to connect the Programming Box to the Comm Port of a PC).

Programming Adapter Lead. (A cable to connect the Programming Box to an SPX2000 series (SL70) Radio.

SMP4001 Software. (The latest known version is Version 4.30 dated 17/7/91)

The SMP4001 will program the following Maxon Radios:-

Maxon SPX2000 series (SL70)

Note that only some SL70s can be programmed with this kit. They should have a label on the back identifying them as an SPX2000 series radio, but this is generally missing. They can be identified by the fact that they have an eight pin program header at the top left corner of the PCB just below the antenna. Note that these radios can also be programmed via the mic socket by using the Maxon SMP4004 software.

Maxon SMX4000 series (PM150)

These radios are programmed by removing the 93C46 EEPROM from the radio and inserting it into a zif socket on the Programming Box. There are two sockets enabling EEPROMs to be copied. Note that these radios can also be programmed via a 3 pin connector on the daughter board by using the PROGSMX software.

No circuit details of the SMP 4001 are known. To program SPX2000 series (SL70) radios it is easier to build the Programming Adaptor PCB and use it with SMP4004 software. To program SMX4000 series radios use the SMP4002 Programming Lead and PROGSMX software.

SMP4002 PROGRAMMING LEAD

As supplied by Maxon this consists of a 25 way D type connector for connection to a PC Comm Port. The interface circuit is built into the D type connector. The D type connector is linked by a cable to a 3 pin connector which plugs in to the daughter board of a PM150 or PM150S radio.

I have no further details of this interface.

PROGRAMMING ADAPTOR PCB

As supplied by Maxon this consists of a 25 way D type connector for connection to a PC Comm Port. The interface circuit is built into the D type connector. The D type connector is linked by a cable to a six pin Hirose connector, which plugs into radios such as the SL70.

This interface probably works with all radios having a six pin Hirose socket as long as the correct software is used.

In some cases, for example when programming SL500 radios it may be necessary to modify the interface. The modification consists of inserting a 10MFD 16VW capacitor in series with the yellow wire going to PL1-4. The modified adaptor still works with SPX2000 series radios and probably with other radios as well.

IDENTIFYING SPX2000 SERIES RADIOS

I had some difficulty in programming my Maxon SL70 until I realised it was actually an SPX2000 series radio!

This top panel of these radios has SL70 written on it. Also on the top panel are the off/on/volume control knob, the channel selector knob, a six pin Hirose socket, a two colour LED, the antenna socket and a locking press buton, which is the HI/LO output power select switch.

The loudspeaker "grille" has horizontal slots. NOT diagonal slots or round holes.

If you remove the front panel it should have only the loudspeaker and mic mounted on it. If there is a PCB screwed to the rear of the panel, then the radio is NOT an SPX2000 series. Having removed the panel you should see an eight pin header just below the antenna socket. This is used in conjunction with the SMP4001 Programming Kit.

I have recently seen a picture of what is said to be an SPX2000 C series radio. This has a front mounted keypad. I have no info on how to program C series radios.

The radio should have a label on the back identifying the model number, but generally this is missing. The model number takes the following form:-

SPX2$50£*, possibly followed by a C.

$ indicates the frequency band . 5 = VHF

8 = UHF

£ indicates the chanel spacing. N = 12.5KHz

M = 20 KHz

S = 25 KHz

* indicates the portion of the band covered. A = 400-420MHz

B = 420-440MHz

C = 450-470MHz

D = 470-490MHz

E = 490-512MHz

F = ??????????

L = 135-150MHz

M = 148-162MHz

H = 160-174MHz

A C on the end of the model number indicates version C software.

As an example a model SPX2850SB radio is a UHF unit with 25KHz channel spacing covering the band 420-440MHz.

IDENTIFYING SMX4000 SERIES RADIOS

The radio should have a label identifying the model number, but generally this is missing. The model number takes the following form:-

SMX4$50£*

$ indicates the frequency band . 0 = 66-88MHz

1 = 132-174MHz

4 = 390-520MHz

There are also versions covering 300-308MHz and 336-344MHz, but I have no further info.
