Programming the Simoco SRP Portable For GPS
Generic guidelines for the programming of Simoco
SRP9120 and SRP9130 portable radios for use with
the MRMap GPS Tracking Application.

MRMap Development Team 21/07/2008
On the opening page of the Simoco programming software application, ensure that
the Frequency range is correct for the channels you will be programming and that
the Accessory option has been set to RSM-GPS, the GPS speaker microphone.
Failure to do this will mean the programming page for the microphone is not later
displayed.
The Radio Type will be either SRP9120 (No Keypad) or SRP9130 (Full numeric
keypad)
Programming for use with a GPS microphone.
The programming software is available free of charge from the TMC website at
www.tmcradio.com (Note: The version on the Simoco website is not usually current)
Connection between the radio and the computer running the software is via the
programming lead supplied by Simoco.
Initially, connect the radio and switch on, select Read Radio from the menu
options and this will upload the current configuration file from the radio. This can be
modified as required and reloaded into the radio.

On this next page the only things of note are what you would like to be displayed
on screen when the radio is switched on, here it’s the name of the radio’s user
shown under Power-On Text.
The Backlight Timer can be adjusted to whatever you wish and is, as the name
suggests, the time during which the screen back light will be on whenever a
function button is pressed or a message has been received by the radio.
Auto-Lock Keys is used to prevent accidental pressing of any of the function keys
and is released either by pressing the ‘OK’ button on the radio for a few seconds or
by pressing the ‘C’ button on the GPS speaker microphone. Again for a few seconds.
The lock will automatically reset itself after a few seconds.
Always allow Side Keys refers to the two function buttons above the PTT bar.
These can be programmed for a variety of functions and are independent of the
KeyPad Lock if this option is checked. Some teams use them for channel changing
rather tan the front mounted + and—keys as they are recessed and difficult to
press accidentally.

The Minimum Speech option sets the lowest volume level for a received signal
and if set above 0, ensures that incoming signals are never completely inaudible.
Key Beeps Enabled and Invalid Key Alerts do what you would expect and are a
matter of personal preference as to whether they are used or not.
The Battery Low Alert is a local warning tone sounded when the battery level
drops below a factory set point.
The Default Mute setting depends on the level of local RF noise and is usually set
at 3. A setting of 0 will permanently open the receiver mute gate. Beyond a setting
of 10 the radios become noticeably deaf.
The Minimum Mute can be changed from the default value of 0 if a Mute Adjust
menu option is available as this prevents the user from ever completely disabling
the muting system.

All the function buttons from F1 to F7 can be individually programmed for a variety
of functions as can those on the speaker microphone. If programmed they may or
may not be subject to the condition of the KeyPad Lock depending on the function
selected and other parameters.
Selecting any option box and pressing F1 will bring up the context help file.
Here the + and - keys are programmed for sequential channel changing and the
‘M’ button (F1) is programmed to enter the menu list. These are fairly obvious uses
but other keys can be programmed to do the same job if required. If not needed,
the buttons are left programmed as ‘Undefined’.
Note: ‘Reset’ is not the same as ‘OK’ as far as the radio is concerned.
Buttons on the speaker microphone can be programmed to duplicate any of these
functions or to allow other functions to be accessed.

MRMap Development Team 21/07/2008
A similar set of functions to that shown on the previous page can be programmed
into the speaker microphone buttons but equally, they can be left unprogrammed if
preferred.
Both the orange buttons, F7 on the radio itself and F10 on the speaker microphone
can be programmed with the FFSK alarm function (see later). In this case only, they
are independent of the KeyPad Lock.
Although there is nothing to prevent further experimentation, the settings shown
under ‘GPS Settings’ have been shown to work well. The two values set to 0
cause the GPS engine to be powered up all the time. This is the most costly in
terms of battery consumption and will require a further 80mA to power the GPS
engine. To date this has not caused any battery life problems.
The Man-Down function monitors the vertical angle of the speaker microphone but
is not used due to the likelihood of the microphone deliberately being placed in the
condition where it would trigger the alarm such as when attached to a ruck sack
which is subsequently placed on the ground.

As with the programming of the function buttons, the menu options are selected
from those available in drop-down lists. Individual menus are operationally selected
by pressing the ‘M’ button (if suitably programmed) followed by ‘OK’ to confirm the
choice of menu required.
In the case of the Mute Adjust menu, pressing the + and - keys will adjust the
current mute level but this is active only as long as the radio is switched on.
In the case of the others shown here, Send Message allows a text message to be
sent via the keypad, to another radio.
Stored Messages lists the messages received by your own radio and pressing the
programmed ‘Reset’ key will delete these messages one by one.
User CTCSS allows the active CTCSS tone to be changed. Again, this function is
only effective whilst ever the radio is switched on. It will revert to the default
settings after being switched off and on again.
Note, a valid CTCSS tone must be programmed into either receive or transmit in
order for this function to operate. It’s not necessary for BOTH receive and transmit
to have such a tone programmed however. User CTCSS will allow the tone to be
changed only where there is a tone programmed in the first place.

If Level 3 programming is available in your version of the programming software
then this page will be displayed. Nothing needs to be changed from the default
settings apart from Compressor Gain which has been shown to give better
transmitted audio whilst not degrading the transmitted FFSK data.
To open the level 3 audio page, you need a password. You can get this from
myself via the MRMap website contact address.

Channel information is entered one channel at a time and is self explanatory. The
SRP9120 can handle 200 channels and the SRP9130, 1000
After adding the required information for the number of channels you intend to use,
the Channel Table will look something like the screen shot below. Scan banks can
be added if required by selecting the Add Scan/Vote Group option and adding the
numbers of the channels to be included in the scan bank.

MRMap Development Team 21/07/2008
In versions of the software above 5.36 the ability to select which channels can send
FFSK data has been added. The channels will default to sending FFSK and should
you not wish to do this on a specific channel or channels then you must check the
No FFSK ANI option for that channel under the Selcall options page.
