AMX-MA-00657 Issue: 1.02 (USA) Page 6
5.2.8 Upgrading From TMP to DMR-25
The DMR-25 programmer has new features not available in the TMP programmer. If DMR-25 is used to
upload channel table data which was programmed into a transceiver with TMP, the data elements
describing the new features will be uninitialised, and may need manual editing afterward. By following the
procedure below you can avoid the need for manual editing when upgrading to DMR-25.
DMR-25 Upgrade procedure:
Step 1 - Transceivers with channel tables which were programmed with TMP should be read back with
TMP and the BCF file saved to disk. You can skip this step if you already have a saved BCF file.
Step 2 - Load the BCF file into DMR-25 using the File->Open menu items. When loading the file, the
DMR-25 will set the new features to the default (disabled) state. The new features, in the Channel Settings
dialog are: Channel Name, Squelch System, Squelch Group, CDCSS Invert, Autosense TX, Courtesy
Tone Tail. See section 5.4.1.
Step 3 - If you wish to use any of the new features, update their settings in the Channel Settings dialog .
Particularly check the PTT Delay setting if you enable it, because the format has changed.
Step 4 - The BCF file is now ready to be written back to the Transceiver, or saved to disk.

Channel Selection
Channel Name: The name of the selected channel is shown in the Channel Name window. The channel
name can be changed by overwriting the existing name in the window. The name is limited to 8 characters
in length.
Channel Number: The channel number is displayed in the Channel Number window. When a channel is
created with the Add command, a sequential default channel number appears here and may be edited. The
channel number of established channels may not be edited.
Channel Type
A channel can function as either a Fixed Channel or a Scan Channel. A Fixed Channel is a “real” channel
used to transmit and receive voice messages. A Scan Channel holds a list of Fixed Channels through
which the radio will scan in receive mode. The channel type is selected by clicking the “Fixed” or “Scan”
radio button in the “Channel Type” box.
Fixed Channel
Installation and Operator Handbook Programming and Configuration
AMX-MA-00657 Issue: 1.02 (USA) Page 13
Mode: Click as required to select the operating mo de for the channel between basestation and
repeater. In repeater mode, all valid inbound signals are repeated on the outbound channel. In base-
station mode, valid inbound signals are not repeated.
Control: There are four functions/options that may be selected, Local control, Tone control, Line
control and None.
Local control: is via a DTMF microphone connected to the DMR-25 Transceiver Module audio
connector elsewhere this is described as the front panel connector. DTMF tones can be used to
configure/control the radio.
Tone control: is via an industry standard tone remote control unit connected to the DMR-25
Interface Module line connector. Tone remote tones are used to control the radio.
Line control: uses the rear panel audio port for control but disables tone remote signalling. When a
4-wire interface is used, control is achieved by E+M signalling. When a 2-wire interface is used,
the radio is capable of making and receiving PSTN calls. In this mode call setup, dialing and
cancellation is controlled by the subscriber radio using DTMF or Project 25 signalling.
None: no control option is active.
NOTE
Control options are only available on DMR-25 Radios fitted
with a controller module. Control options will be ignored by
radios which are fitted with the Timing Module as a
replacement for a Controller Card.
Signal Type: Select the channel mode from the list of Analog, Project 25 and Autosense modes.
Bandwidth: This setting determines the peak deviation of the transmitted signal, and the channel
bandwidth used in the receiver. Select the required channel bandwidth from the list, to set
wideband or narrowband analog or autosense operation. Wideband operation should be selected
for use with analog systems employing 25 kHz or 30 kHz channel spacing. Narrowband operation
should be selected for use with analog systems employing 12.5 kHz or 15 kHz channel spacing.
Squelch System: Select the type of analog squelch required between CTCSS and CDCSS.
Group Enable: When selected, the squelch system selection is disabled and a Squelch Group is
required.
Squelch Group: Select from a list of Squelch Groups, which are defined in Program/Squelch
Groups see section 4.5 Squelch Groups. The Squelch System will determine which analog
squelch is used in a squelch Group.
Link Radio: Select to enable the Transceiver Module for cross-band and cross-mode operation.
This selection will be disregarded by the transceiver if it is not licensed to support Link Radio. See
Section 4.6 License Features.
Enable Front Panel PTT: Select to permit transmissions to be made from the microphone
connected to the DMR-25 Transceiver Module Front Panel audio connector.
NOTE
Installation and Operator Handbook Programming and Configuration
AMX-MA-00657 Issue: 1.02 (USA) Page 14
Link Radio cannot be selected when Enable Front
Panel PTT is enabled and vice-versa.
Half Duplex: When half-duplex mode is selected, the receiver is disabled when transmitting and
vice-versa. Half-duplex operation is only available in base-station mode.
Receive/Transmit Configuration
Freq (MHz): Enter the receive and transmit frequency for the selected channel. Note that the VHF
radio frequencies can be set to 1Hz precision. However for the UHF radio, entered frequencies are
internally rounded to a multiple of 5.0 kHz or 6.25 kHz (whichever is nearer) regardless of what is
displayed or entered in the frequency dialog.
When the DMR is operated in full duplex (simultaneous reception and transmission) isolation is
required between the receive and transmit signals to ensure that the receiver is not de-sensed by the
transmitter. The isolation is generally provided by a separate antenna or external RF combining
network. Table 5-2 and Table 5-3 show the minimum and recommended isolation levels for VHF
and UHF-Lo respectively.
Table 5-2 VHF Receive/Transmit Spacing
Receive/Transmit Spacing Minimum
Isolation Recommended Isolation
<600 kHz - Not recommended
600 kHz to 1 MHz 85 dB >100 dB
1 MHz to 2.5 MHz 70 dB >80 dB
>2.5 MHz 60 dB 80 dB
Table 5-3 UHF-Lo Receive/Transmit Spacing
Receive/Transmit Spacing Minimum
Isolation Recommended Isolation
<600 kHz - Not recommended
600 kHz to 1 MHz TBA TBA
1 MHz to 2.5 MHz TBA TBA
>2.5 MHz TBA TBA
Due to harmonics of internal clocks and oscillators degradation of receiver sensitivity may be
experienced on the following specific frequencies, and these frequencies should therefore be
avoided:
140.000000 MHz, 150.000000 MHz, 157.287500 MHz, 160.000000 MHz and 170.000000 MHz.
NAC (Network Access Code). For Project 25 / Autosense operation select the NAC as required,
using hexadecimal (Hex) notation. Receive and transmit NAC may be set independently, or the
transmit NAC may be set to be the same as the received NAC (‘Same as Rx’). If analog channel
mode is selected then these boxes will be disabled. Click on the Up/Down Arrows to
increase/decrease the current NAC value.
Installation and Operator Handbook Programming and Configuration
AMX-MA-00657 Issue: 1.02 (USA) Page 15
The DMR radio can be programmed to un-mute on any NAC by entering the NAC values 0xF7E
and 0xF7F as defined in the Project 25 suite of standards.
CxCSS: Receive and transmit CxCSS may be set independently or the transmit CxCSS may be set
to be the same as the received CxCSS (‘Same as Rx’). If APCO 25 channel mode is selected then
this box will be disabled. Click on the Up/Down Arrows to increase/decrease the current CxCSS
value.
CDCSS Invert: Select to invert the CDCSS encoding string pattern for both receive and transmit.
Autosense TX: Selects the Transmit type (Analog or Digital) when a PTT from the front panel
microphone or rear panel 4w/2w interface has been asserted on a channel whose signal type has
been programmed as "Autosense".
Encryption
Algorithm ID: The DMR-25 Programmer currently supports clear transmission and DES-OFB
algorithm.
Key ID: The Key ID may be a number between 0x0000 and 0xffff.
See Section 4.4 Encryption Settings for details.
Timers
PTT Tail (sec): Enter the amount of time the DMR continues to transmit a carrier signal after the
Press To Talk is released, or click on the up/down arrows to raise or lower the Tail time in 0.1
second increments to a maximum of 9.9 seconds.
PTT Delay (msec): (Applicable to Base-station Mode only) Enter the amount of time the Tx/Rx
changeover relay is allowed to stabilize before RF power is applied, or click on the up/down arrows
to raise or lower the Delay time in 1 millisecond increments to a maximum of 99ms. Set to zero if
no changeover relay is used.
PTT Timeout (sec): Enter the maximum duration of continuous transmission in seconds, or click
on the up/down arrows to raise or lower the Timeout in 1 second increments to a maximum of 255
seconds. If no transmission length timer is required, set to zero.
Courtesy Tone
Courtesy tone is only applicable in repeater mode.
Tail (sec): Enter the desired duration of the courtesy tone to follow analogue voice transmissions
initiated from the front panel microphone or rear panel 2w/4w interface, or click on the up/down
arrows to raise or lower the Tail time in 10 millisecond increments to a maximum of 9.99s.
Tone (Hz): There are four options available, None, 400Hz, 1000Hz and 2500Hz.
Reverse Burst: Reverse Burst is a feature designed to minimise the squelch crash at the end on an
analogue transmission. If the reverse burst check box is selected in an analogue transmit mode then
at the end of a transmission the CTCSS tone phase will be inverted for CTCSS channels or the
CDCSS "turn-off" signal will be transmitted for CDCSS channels as described in TIA/EIA 603.
When this box is selected, the Courtesy Tone tail setting determines the burst length, and Tone
Installation and Operator Handbook Programming and Configuration
AMX-MA-00657 Issue: 1.02 (USA) Page 16
setting is ignored. The tail time should be selected to optimise the performance of the particular
analog mobile used in a system.
General
Talk Group ID: Select or enter the Talk Group ID for Project 25 transmissions from the DMR in
basestation mode.
Unit ID: Select Unit ID for the Base-station Unit.
Power (Watts): Enter the transmit output power for the channel or click on the up/down arrows to
raise or lower the output power in 1 W increments. Because internal communication with the PA is
slow, around 30 seconds will elapse after radio startup before this setting becomes active. During
those 30 seconds, the transmitter, if keyed, will transmit at full power.
Scan Channels
A scan channel consists of two or more fixed channels. The DMR-25 will step through the list of
fixed channels until it finds one with a valid receive signal. The Channel Settings Dialog Box
displays a list of fixed channels with their dwell times. Use the Add, Edit and Delete buttons to
manage this list.
Add: Adds a reference channel to the selected scan channel list using the Configure Scan
Channel Reference Dialog Box shown in Figure 5-7. Select a fixed channel in the Reference
Channel field and nominate a Dwell Time. Dwell Time is the period, in seconds, for which the
DMR will monitor a particular reference channel given ceased activity on that channel. The selected
reference channel is then added to the scan channel when the OK button is clicked or discarded if
the Cancel button is clicked.
Edit: Changes the parameters of a preconfigured fixed channel.
Delete: Deletes the highlighted reference channel from the Scan Channel list.

5.4.4 Encryption Settings
Program/Encryption Settings opens the Encryption Settings Dialog Box as shown in Figure 5-10 listing the
currently configured Encryption keys. If an encryption key is entered, and its Key ID matches that of an
incoming transmission, the key will be used to decrypt the transmission. Up to 16 keys can be entered, and
the transmission will automatically select the correct key which matches the incoming Key ID.
NOTES
1. Encryption Keys, once configured, cannot be reviewed.
2. If the radio is not licensed for the encryption feature, the
encryption keys will be ignored (see Section 7 License
Features).
Figure 5-10 Encryption Settings Dialog Box
To Add an Encryption Key click ADD and the Add Key Dialog Box appears as shown in Figure 5-11.
The required key is entered into the eight 2-hex-digit boxes using the Tab key to move between boxes.
Note that each 2-hex-digit code must have odd parity. The DMR-25 programmer will check and report any
errors of the entered encryption key. Next, enter a Key ID between 0x0000 and 0xFFFF. When the
desired Encryption Key and Key ID are entered, click OK and the new key will be listed in the Encryption
Settings Dialog Box.
Clear Key: In the Add Key Dialog Box, an entered key can be cleared by clicking the Clear Key button.
Generate Random Key: To add a random key, click Generate Random Key button and assign a Key ID.
At any stage, the CANCEL button can be clicked and the key will not be added to the list.
Delete: To delete an existing Encryption Key, highlight the desired key and click DELETE.
Close: When satisfied with the list of Encryption Keys, click CLOSE in the Encryption Settings Dialog
Box.

5.4.5 Squelch Groups
Program/Squelch Groups will display the Active Squelch Groups Dialog Box as shown in Figure 5-12.
This lists the currently configured Squelch Groups. Groups of squelch tones are used to allow a repeater to
retransmit a signal containing any one of a number of different squelch tones or codes.
Figure 5-12 Active Squelch Groups Dialog Box
Add: To add a squelch group, click ADD and the Squelch Group Properties Dialog Box appears as
shown in Figure 5-13. Enter a name for the new squelch group in the Squelch Group Name Field. Then,
by clicking the up/down arrows, select the desired squelch value for the squelch system and click the
appropriate Left Arrow to add the selection to the list.
NOTE
Multiple values for the same squelch system, and multiple squelch
systems, with the exception of the CDCSS and CTCSS case, can co-
exist in the same squelch group. The DMR-25 radio will use the
appropriate values in the group for the selected channel.
Items within the list can be deleted by highlighting the desired item and clicking DELETE. When
satisfied with the list click OK and the new list is entered as a new squelch group and displayed in the
Active Squelch Groups Dialog Box. Alternatively, click CANCEL and all additions and/or changes are
ignored.
Edit: Squelch groups can be edited by either double clicking on the appropriate group or by highlighting
the group and clicking EDIT. The Squelch Group Properties Dialog Box displays the configuration of
the selected group where items can be added, altered or deleted as required.
Delete: Existing squelch groups can be deleted by highlighting the required group and clicking DELETE.
When the list of groups is finalised, click OK or click CANCEL and the changes will be ignored.

5.4.6 License Features
Although all of the software described in this manual is contained in the DMR-25 transceiver software,
some features require a license key before they become active. If no keys are present, the transceiver
software will ignore any settings made via the DMR-25 Programmer which require a license key. Current
license key features are Link (Section 5.4.2) and Encryption (Section 5.4.4).
Licenses can be displayed in Program/License Features as shown in Figure 5-14. Licenses cannot be
added or deleted "off-line". The DMR-25 Programmer must be connected to a transceiver to use this
feature. Licenses can be added by clicking Add License where a 25-digit string should be entered as
shown in Figure 5-15. The transceiver license string is updated immediately "OK" is clicked in the dialog.
Contact your supplier to obtain the license string.
Licenses can be deleted by highlighting the required license and clicking Delete License. When satisfied
with the license structure, click OK to return to the DMR-25 programmer main screen.

5.4.7 Change Password
The programming details of a DMR-25 Radio may be protected from unauthorised use by the inclusion of
a password. Setting a password in the radio will mean that the programming information of the radio
cannot be viewed or changed without first entering the correct password.
To change the password, from the main menu activate the Program pull-down menu and select Change
Passwords. The Change Password dialog box will appear as shown in Figure 5-16. Like license strings,
passwords can only be changed if the DMR-25 Programmer is connected to a transciever.
Figure 5-16 Change Password Dialog Box
Enter the old password, followed by the desired new one. If no password is currently set, leave the “Old
Password” field empty. Enter the new password again in the bottom field for verification and click OK.
The Tab key may be used to move between the text boxes. To remove the password from the radio, enter
the old password in the “Old Password” field and leave the “New Password” fields empty.
NOTE
Transceivers are shipped without active passwords and no password is
required for normal operation. Earlier transceivers were shipped with
the default password “1234”. If the DMR-25 prompts for a password
unexpectedly, try “1234”.
If you forget the password for a radio, contact your Westel distributor.
