PROGRAMMING THE MDS SPEAKER
1. Speakers should be programmed before installation.
2. Power on only the speaker you want to program and wait for its power-up chime
before you start programming. Speakers are “powered on” when plugged into
a power source and/or their battery back-up switch is turned on with a charged
battery. Note: It may take up to 40 seconds for the speaker to boot up.
3. If programming more than one speaker, make sure that the other speakers are
unplugged and their battery back-up is turned OFF so that they do not interfere
during programming. Repeat this process for each speaker as you program
additional speakers.
4. With the speaker on, insert the USB Bluetooth Dongle into an available USB
port on the computer. (Speakers must be turned on first to hear a unique
“Connection chime”). Use only one programming dongle & computer at a time
to prevent interference when programming. Speaker and PC should be within
a few feet of each other so that the Bluetooth connection can occur.
Programmer does not need to be running for dongle to connect to the speaker.
PC PROGRAMMER
1. Install CPS Radio Speaker programming software onto the PC that has the
programming dongle.
2. Run CPS program and it will open to a blank page. You will need to read the
speaker or pull up a previously saved speaker file (.bin). If this is your first-time
programming, “read” the target speaker first by following the next couple of
instructions.
a. Select the COM port. If you unsure of the port number it can be found in the

Device Manager on your computer. The driver for the dongle is made by
Silicon Labs. In this instance it is COM8.
You will receive an error if the wrong COM port is selected.
b. Read the MDS-Speaker via the pull-down selection at the top under
“Programming” or by selecting the Read icon.
The reading process may start slow, but should take less than a minute.
If you get a read failed error, restart the process and make sure your
speaker is plugged in and turned on.

**If you are working with a previously saved speaker file:
a. Get to the main page and select “File” or the “Open” icon.
c. Locate the (.bin) file you previously saved to your computer, click on the file,
& open it in the CPS programmer.
3. Information stored in the speaker will now be displayed. Various items are selected
from the tree view on the left side of the screen. A description of each is shown
below.
Speaker Information
Displays technical information about the speaker. Items on this screen cannot be
edited.

Basic Settings
a. Speaker Alias: Alphanumeric name or number that will represent either
the speaker model number or the location of the speaker. Example:
Warehouse.
b. Boot Zone: Zone has a maximum or 32 channels as Channel Members.
These members correspond to the channel number. Members can be
arranged by moving a channel up or down in the list.
c. Speaker Audio Level: Volume is adjustable from 0 (mute) to 10 (loudest).
d. Current Channel: The current channel is settable by selecting the
channel index configured in the Zone.
e. Announcement Chime: When enabled, the speaker automatically emits
ascending tones at the beginning of a transmission to “introduce” the
subsequent incoming audio. When the person transmitting stops, the
speaker emits descending tones to signal to the listener that the
transmission has ended. You would use this feature to draw attention to
incoming announcements about to be broadcast through the speaker.
Zone
A zone can consist of digital, analog or mixed channels. This list of
channels would consist of your most frequently used channels. The
first channel member in the zone becomes the channel used for the
speaker. Only one zone is available. A maximum of 32 channels can

be in the zone.
Channel/DMR Menu
a. DMRDigiCh displays the ID of the speaker along with digital channel
information.
b. This chart makes it easy to create a list of channels by automatically
creating the number of channels, the channel name, color code and slot
number. There is a maximum of 502 channels.
c. In the example above, 109 channels were created. Start frequency was
input with an offset of 0.0125. It starts with Color Code 2 and is
incremented by 1 for each channel. When it reaches 15 for the Color
Code, it is repeated 0-15 sequentially for each set of 16 channels. “Apply”
must be clicked to save the changes. All of the fields can be edited if
needed.
DMR Digital Channel Edit

a. Channel Alias is the name that shows up on the display of the radio.

automatically. In this example it created 9 channels with the name of
each channel called “Analog ChannelX”. “X” is automatically
incremented from 1-9. Maximum number of channels is 402.
b. Start Frequency is 450.0125 and incremented by 0.0125 for each
channel created. CTCSS tones start at 67Hz and every 2nd tone is input.
This is the Tone Offset.
c. Squelch Level, Tail and Bandwidth are also selectable (see below).
d. Apply and Save to write the channels to the programmer.

Analog Channel Edit
a. Channel Alias is the name that shows up on the display of the radio.

g. RX DCS selects the DCS code or the Reverse DCS code.
h. RX Squelch Level adjusts the squelch from open squelch (0) to tight
squelch (5).
Mixed Channel Edit

A mixed channel allows the speaker to receive either a digital channel or an
analog channel without changing the channel on the speaker.
a. Channel Alias is the name that shows up on the display of the radio.
b. Digital Channel Type can’t be edited.
c. Digital Available Channel can be any channel in the DMR Digital
Channel list.

MDP-6424 Programming & Operation w/ MDS Speakers
Maxon’s MDP-6424 is currently the only radio model available to remotely adjust the
volume of a speaker without the CPS program. Any DMR UHF radio or UHF analog
radio can talk through the speakers, but they cannot adjust the volume.
You will need:
•Programming cable ACC-3320E
•MDP-6424 CPS Software will need to be ACC-640 version V2.0.0.6 or higher
•MDP-6424 Radio firmware version V2.5.1.0 or higher
a. Using the correct version of software, read the radio. In this example we are
using V2.1.3.2. Contact Maxon if you need updated software.
b. In the Settings menu select “MDS Set”as shown.
c. Under Buttons, MDS Set (D) can be selected. This allows direct access to
the MDS speaker adjustment. There are 4 options under this menu.
1. MDS ID: Allows the user to manually input the ID of the speaker to be
adjusted.
2. MDS Contacts: Displays the Call Type “MDS Call” generated in the DMR
Contact list.
3. MDS Volume: Sets the volume level of the speaker.

4. MDS Set: Sends the ID and volume level information to the speaker.
d. From the top left button on the front of the radio, “Contacts” can be selected
and the MDS speaker to be adjusted. There you can view the speaker ID
number and set the volume.
e. A digital channel or analog can be used to talk through the speaker. Once
these are setup make sure they appear in the zone as a Member. Special
note: Only a MDP-6424 in digital mode can set the volume of a speaker.
f. Under DMR Setting/DMR Contacts, there are 4 Call Type selections
available.
1. MDS Call: Used to add speakers to the contact list. Call ID can be found
on the bottom of each speaker.
2. Group Call: Used to call a group of speakers or a group of individuals.
3. Individual Call: Used to call a specific individual. This is not the same as
the MDS Call.
4. All Call: A call made to all speakers and/or persons.

MDP-6424 Operation
1. Turn on the radio and also the speaker you wish to adjust.
2. There are 2 ways to access the speaker volume adjustment on the radio.
a. One is by pressing the “menu” button and selecting “Contacts”. Scroll to find all
of the contacts programmed into the radio. Contacts with this symbol, are
MDS speakers. Next press the “menu” button again and there you will find 2
options; 1. View Details and 2. MDS Set. Looking at the details will show the
speaker ID of the selected speaker. “MDS Set”allows you to adjust the volume
level of the speaker. When the level is selected, press the menu button again
to send the information to the speaker. The radio will show “Send Message”. If
the call is successful, you will hear a 4-tone chime from the speaker.
b. The other way is to use a predefined button press called “MDS Set (D)”. In this
example we have it programmed on P1. “MDS Set (D)” has 4 settings. Each is
explained below.
1. MDS ID: Use the menu button to select MDS ID. There you must enter the
8 digits shown on either the bottom of the speaker itself, or the number
found in the programmer as “Own ID”. The menu button moves the curser
to the next digit while the scroll key changes the number either up or
down. After the 8th digit is entered, press the menu button again and this
will return you to the main screen. (At this point you would skip down to

number 3, bypassing number 2 “MDS Contacts”.
2. MDS Contacts: This list only shows the MDS speaker contacts. Press the
menu button to see the speakers. Scroll and select the speaker you wish
to adjust the volume. Next move to step 3.
3. MDS Volume: Use the scroll button to adjust the level of the speaker
volume. Press the menu button to set it.
4. MDS Set: This shows the speaker ID you wish to set along with the
volume level. Press the menu button again to send the message. You
should hear 4 tones indicating the level has been changed.
