TECHNICAL NOTE TN-1038b-SR
TM8100 Firmware v2.09
and Programming Application v2.92
25 July 2005
Applicability This Software Release Note applies to the TM8100 Mobile Radios.
1. Firmware Changes
Resolved Issues It was found the Audio DSP did not reset the Audio Tap Out line to
zero volts when the audio line goes idle. This caused a DC offset which
impacts some third-party equipment. The firmware was changed so
the signal processing forces a zero to the DAC when the signal
processing is idle. Raised as Focus 20304.
An issue raised by a TEU customer using the TMAA10-01 Desktop
Microphone was that occasionally the radios would not transmit.
The problem was traced to a very large bouncing ‘spike’ that was so
long the radio was not interpreting any change of state between the
PTT switch being keyed and the PTT input being read. This was solved
by re-enabling of the I/O line interrupt to happen before reading the
current status of the line. This change doesn’t impact normal PTT.
Raised as Focus 20844.
It was noted during extensive testing of TM8100 and TM8200 Vote
Group testing that the field Validate Signalling While Voting is enabled
be default. The 'channel' outcome at the end of a “Vote Pass” is the
same regardless of whether this setting is enabled or not, except it can
take 250ms per channel longer with this tickbox enabled even on
non-signalling groups. As requested this tickbox is disabled by default
now but can be enabled for Groups that do use signalling.
Raised as Focus 19865.
Resolved an issue where the Programmable I/O option
Mute Audio Output Path would become disabled if the personality was
either written to the radio or saved to disk. Raised as Focus 20792.
Emergency ANI has been corrected. When in Emergency mode the
Emergency ANI sends the correct ID together with the Emergency
status. However once acknowledged, and the TM8100 goes into
Cycling, the ANI appended has a non-emergency status.
Raised as Focus 20091.
Resolved an issue that occurred when you selected a Scan Group if the
radio also had THSD enabled. This caused an ‘E1’ error to display. This
was caused by a missing validation. Raised as Focus 21144.
Fixed an issue with Repeater Talk Around (Function Key option) where
it was not de-activated when a group was selected by another
function key, but was for a group that was accessed by scroll keys.
Raised as TIMS 43980.
Corrected an error where ‘R10’ (set as the Rx Tap_In on the
Programmable I/O Audio page) and the radio had a Powerup State set
as THSD Transparent Mode would cause the radio to reset.
Raised in TIMS 44634.

2. Prog App Changes
Power-up
Changes The Programmable I/O option Toggle Standby Mode has been
renamed Power ON (Stand-by).
The Programmable I/O option Power Sense (Ignition) can only be
assigned to AUX_GPI3 and can only be active HIGH.
Although the Programming App allowed it, the Hardware was not
designed to work with this line as active Low.
When Action Enter Emergency Mode is selected for AUX_GPI2, then
the line can only be active LOW. This option can only be assigned to
either AUX_GPI2 or IOP_GPIO7.
A new Programmable I/O option has been created called
Power Sense (Internal); this Input action can only be assigned to
IOP_GPIO7 and can only be set as active HIGH.
Invalid
Confirmation
Delay values
Invalid Confirmation Delay found in Networks > Basic Settings
> Subaudible Signalling can now be adjusted between the values of
0 and 1000ms. The default is 20ms. This value defines how long the
signalling (CTCSS or DCS) on the carrier has disappeared before the
receiver closes the mute. This was changed as a result of requests from
some users.
Some very early production radios had this value set at (0) in error and this
would cause a pop-up error when read into a newer application. Unless
there is a requirement by the user for (0) this should be corrected to 20ms.
Selcall’s that don’t
work?
There have been issues raised by some users who couldn’t understand why
their defined Selcall system didn’t decode.
The Selcall > Tone Settings page allows the Selcall system user to define
the Tone Period and also the Gap Period. The values of these fields are
both defaulted to 20ms, but can be variable from the drop-down box on
the Tone Period and between 10 and 150 ms in the Gap Period.
The most common reason for a radio that won’t decode a Selcall is the
Gap Period has been set to a lower value in comparison to the Tone Period.
The solution is to set the Gap Period exactly the same as the Tone Period,
even if the defined sequences do not use Gaps. The Selcall decoder will
identify the space between individual Tones as valid Gaps and interpret the
incoming format as such. Technically the Gap should be at least 66%
duration of the defined Tone Period.

First Serial Number From radio serial number (TBA) all TM8100 radios built have Firmware
v2.09 installed.
Upgrading existing
radios
For upgrade firmware procedures please follow the instructions in TN-969.
3. Enhancements
TMAA02-08
Keypad
Microphone
Versions 2.09 or later firmware can now support the TMAA02-08 Keypad
Microphone allowing quick/direct channel access.
As shown in the screenshot below, the new field Mic on the UI Preferences
page allows the option of Keypad Mic. When this is enabled the radio will
expect there to be a TMAA02-08 Keypad Mic to be connected and allow
direct entry to any 2-digit channel/group ID.
The keypad Microphone’s backlighting mode will follow the TM8100’s
programmed setting.
Points to Note:
The audio gain of the TMAA02-08 is slightly higher than the
TMAA02-01 standard microphone and if this causes issues for
customer’s it is suggested the Control Head Mic Gain be set to Low.
The Control head port cannot be enabled for keypad Mic if the Data
Port or the GPS Port is already set to Mic.
Once the radio is programmed for the TMAA02-08 it will need to be
powered-off and on when reading and writing in the same fashion as
transparent data as the port is only expecting data from the Mic.
When entering channel ID’s two digits are always required
i.e.: Channel 8 is entered as ‘08’. The user has 3 seconds after the first
digit to enter the second digit. If this time expires OR the requested ID
does not exist the radio will revert to the previous channel ID.
The up/down scroll keys function in the same way as the front panel
buttons, but the two ‘function’ keys to each side of scroll have no
function.
The TMAA02-01 standard microphone can still be used if required.
High VSWR
Alarm
The TM8100 will now emit from the speaker a single two-tone warble on
PTT when a Standing Wave Ratio greater than 5:1 is measured. The radio
will automatically change to Very Low RF power (1W) on the 25W radios
and 10W on High Power models for the duration of each high VSWR
transmitted carrier.

Transmitter Lead-Out
Delay
A new field has been introduced in the Programming Application providing
a transmit ‘hold’ timer. The PTT Deactivation Delay can be set differently on
each PTT tab from 0ms to 1000ms. Default is 0ms.
This duration will hold the radio in its previous transmitting state, complete
with any signalling such as CTCSS, active. When the timer has elapsed the
radio will process the normal PTT release functions such as Reverse Tone
Burst, Trailing ANI etc if enabled.
This helps solve two requirements:
(1) An issue noted for a TCL customer where the radio was chopping off
the last part of external input audio data due to the time required
processing the data through the radio to air.
In this case only a few milliseconds is required. Raised as Focus 18719.
(2) Users who were coupling two TM8100’s together as a repeater
requested a way of encoding a transmitter ‘repeater tail’. This could be
achieved previously by paralleling two EPTT inputs and using different
debounce settings for fast-attack and slow-release. But the maximum
duration available was only 200ms.
This field will also be ported into the next release of the TB7100.
New CCDI
Commands
New Computer Controlled Data Interface query command features added
based on CCTM commands 318 and 319 are:
Request Transmit RF Forward power reading -- q0453185A
Request Transmit RF Reverse power reading -- q04531959
Request current RSSI reading -- q0450645C
The responses for these commands are:
j06318634F7 - Response to a forward power reading, in this case the
forward power reading is "634". The response is an ADC value with a
range from 0 – 3000.
j06319191F8 - Response to a reverse power reading, in this case the
reverse power reading is "191". The response is an ADC value with a
range from 0 – 3000.
j07064-896C1 - Response to an instantaneous RSSI value, in this case the
reading is "-896" or -89.6dBm. The response is a value in 0.1dBm steps in
the approximate range from -1400 (-140.0dBm) to -240 (-24.0dBm).
Originally implemented as a TCI job a2482.

TaitAx
Scanning
TaitAx (also known as MultiAx) is a Scan group type that operates the same
as a Standard scan type until the PTT is pressed or ‘flashed’, then the radio
starts looking for the next free channel that it can transmit on.
If this is the first action after entering Scan the channel chosen will be the
first in the Scan member list.
If the scan group has become idle OR the Group Hold Timer has expired
and a user PTT’s, the radio will select the next channel in the scan list and
transmit on that.
The radio will always transmit on any currently captured channel (until the
Group Hold Timer expires) as per Standard Scan operation.
If no channel is free and the Search Timer duration (variable between 1 and
10 seconds) has elapsed, the Tx inhibit tone [a single low-tone beep]
sounds, and scanning resumes.
Captured Alert, when selected will give the Channel Freed tone
[a triple-beep sequence] when a valid free channel is available.
Search Indicator, when selected will give the Search tone
[a bop-bop sequence] when it is looking for a free channel.
NOTE: this is a quieter level in comparison with the alert tones.
The objective of TaitAx as a Scan type is to utilise all channels (repeaters) in
the area equally by ensuring users are accessing the next repeater.
Note: TaitAx is an optional feature, and can only be enabled in the radio
after obtaining and entering a (SFE) license key. TMAS014.
MDC1200
Signalling
MDC1200 (encode only) Signalling is now supported within TM8100
firmware. Up to 4 different MDC1200 profiles can be defined.
The network can have a MDC1200 profile in the same way as a DTMF or
Selcall profile.
The Radio ID uniquely identifies the radio when transmitting MDC1200 ANI
or emergency sequences on channels associated with this channel profile.
The ID is in 4-digit hexadecimal format (0 to 9 and A to F).
The ANI Sequence and Emergency Sequence can all be defined with
different ID’s if desired.
Note: MDC1200 is an optional feature, and can only be enabled in the
radio after obtaining and entering a (SFE) license key. TMAS012.

CCDI
‘Big SDM’
A number of sales prospects required more than the normal 32 character
Short Data Messages. The CCDI3 command has following format called
“adaptable SDM”, will allow a string of up to 128 characters:
a [Length] [Lead-in-delay] 204BigSdmString [Radio-ID] [Checksum]
Length => 2 character (hexadecimal)
Lead-in-delay => 2 character (hexadecimal)
204 => GFI = 2 (type is ASCII), SFI = 04 (Code is "Big SDM")
Radio ID => 8 characters
Checksum => 2 characters
The example below will send a 128 character SDM to unit 00002233:
a8D192040000223301abcdefgh02abcdefgh03abcdefgh…13abcdef7D
The SDM text data is split into several FFSK frames and put back together
at the receiving radio. The backwards compatibility is maintained, since the
GFI/SFI is not "0", so earlier firmware or other radio models will simply
ignore the received ‘Big SDM’.
Using CCDI to
control a CCR
CCR is “Computer Controlled Radio”. This is the ability to set a TM8100’s
current channel personality in real-time, usually from a PC or similar device.
This enhancement to the TM8100 provides for the ability to convert
received Short Data Messages into CCR commands. This provides the
ability to remote control a TM8100 radio.
The following needs to be enabled as a minimum:
SDM is enabled and the radio unit has a SDM identity.
SDM Format is CCDI3 (only currently available in the TM8100).
Where the CCDI String is built with:
a [Length] [Lead-in-delay] [203] [Radio-ID] [The CCR command] [Checksum]
Length => 2 character (hexadecimal)
Lead-in-delay => 2 character (hexadecimal)
203 => 2 (type is ASCII), SFI = 03 (Code is SDM)
Radio ID => 8 characters
The CCR Command – R09159200000084
Checksum => 2 characters
Example:
A despatch TM8100 radio in CCDI mode can send this string to a remote
TM8100 (ID 00002233) that’s already in CCR mode.
String: a1B1120300002233R0915920000084C3
The remote TM8100 will process the “set receive frequency” command
and change the Rx frequency to 159.200000 MHz.
To exit CCR Mode the string E005B sent will initiate a software reset in the
same way as the “^” character and exit to normal channel mode.
CCR Squelch An addition to the CCR command set is Set Squelch.
This command configures the TM8100 radio’s operating busy detection
criteria. Where the CCR String is built with:
K [ss] [p] [x] [CC]
K denotes the set squelch threshold command
ss is the number of x characters. Always “02”
p is the busy detect method:
“R” determines busy by RSSI.
“N” determines busy by Noise level (SINAD)
x is the Squelch threshold levels:
‘1’ – Country
’2’ – City
‘3’ – Hard
CC is the checksum
This string: K02N3D2 will set the receiver to Hard squelch in a SINAD
(Noise Level) Network.

Proceed to Talk
Tone
This is an audible tone heard from the speaker at the end of a PTT
Leading-Edge ANI to inform the user they are now free to speak.
The tickbox on Networks > PTT Signalling > PTT Press un-greys if the
current network is Selcall and the Signalling on PTT Press is ANI Sequence.
CWID A new tab has been added to Networks > Basic Settings called CWID.
CWID is Carrier Wave Identity. On FM systems tones are used to duplicate
the effect of Carrier Wave being received.
The Tone Frequency can be varied from 400 to 2000 Hz.
The Interval is the time between Strings being sent to air in 1-minute steps
from 1 to 240. The message string is not sent over any active transmission
if
Wait Until End Of Transmission is enabled.
The String can consist of up to 30 elements from the list of:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ.,:?'-/()".
This includes spaces. The default text is "MESSAGE".
The message is sent over the air at a Words Per Minute rate between
5 and 30 in 5wpm steps.
As it is available on a per-network basis, 4 can be defined if required.

Combine and
Combine (0dB)
Originally developed for the TB7100 Base station, a new Tap_In type called
H-Combine 0dB has been added to Programmable I/O > Audio tab in the
Programming Application.
The TB7100 uses T12 Tap-In for MPT1327 trunking applications where
FFSK from the CCM and normal speech audio are both required to be
processed by the transmitter.
Speech audio is applied via Aux_Mic_Aud but it is not desirable to have this
audio scaled by –6dB, using just B-Combine, as this will result in only half
the required deviation and increasing the audio drive level to compensate,
would cause the limiter to prevent this increase being passed on to tap
T12.
1200 Baud FFSK
in T2000-A75
systems
FFSK 1200 baud on the T2000-A75 (data interface board) runs approx
8bps slower than on the TM8100. Some customer’s experienced problems
putting new TM8100’s into those existing networks.
The standard TM8100 implementation has a shorter first frame of 16 bytes
to help get onto the channel quicker. For normal operation this has no
effect on overall modem performance, however transmitted data with long
strings of ‘zeros’ or ‘ones’ results in the first symbol transition following the
long same-symbol string being lost altogether or replicated depending on
the direction of data between the TM8100 and the T2000-A75.
The implemented solution in the TM8100 checks for long strings of ‘zeros’
or ‘ones’ and when the string length reaches 20, the symbol interval for
the next transmitted symbol is increased by one sample.
Found in Data > RF Modems, the drop-down box for FFSK Baud Rate has
the options of 1200 for normal TM8100 operation, 1200 (A75) for use
with existing systems with T2000-A75’s and 2400. This last option is to be
included in later enhancement work on the TM8100.

Correction to
Prog App
The first version of Programming Application in this release was v2.90.
However an error was found where the Transmit Frequency band of
operation for D1 (216 to 266 MHz) was incorrectly limited as
(216 to 226 MHz).
This error was quickly resolved and a new Programming Application has
been released, v2.92. This is the only change over v2.90, so if v2.90 is
installed and the D1 band is not used in your market there is no
requirement to replace your Programming Application.
All CD-ROM’s with TM8100 Programming Applications included,
TMAA20-00 and TMAA20-01, will now include v2.92 as release version.
Compliance Issues None.
