integration of PBX and keyboard module in one device
classic design, continuing the KDC18XX series
robust metal housing
touch-sensitive strain gauge keyboard, used in KDC3000 series top-of-the-line cassettes, the keyboard is
designed for use by blind people
proximity tag reader ‘RFID’and the optional ‘Dallas’tag reader
microSD memory card reader
electronic control of microphone sensitivity, loudspeaker gain and balance (removal of crosstalk)
autosilencer system –automatic tuning of the audio track during conversation
possibility of opening any lock (OC output) from the device and lock button (in configuration with several
satellites)
operation of reverse locks and electromagnetic jumpers without the use of external relays
possibility to update the software through microSD card

Table 1: Keyboard specifications

2 Quick start
The following are the basic steps for basic configuration of KDC1905 system:
1. Insert the memory card into the connector on the main board of device. MicroSD (not SHDC or SDXC) cards
up to 2GB in FAT16/FAT32 format are supported.
2. Enter the installer code.
(a) Enter the programming menu: in idle state, select the button , enter standard access code: “240361”
and the default installer code (‘0000’). After entering the code “240361”, the cassette will briefly
display the used program version.
(b) Enter the program A-7 (select 7 from keyboard and confirm with button )
(c) The cassette will display the current code alternately with an editing message. Delete the old code using
the button
(d) Enter a new installer code, confirm with key
3. Parameters edition:
(a) enter the programming menu ( –>installer code), the cassette should display
(b) after the text is displayed, enter the parameter number (e.g. 208) and accept with key
(c) the keyboard will display the parameter symbol (e.g. ) alternately with its value
(d) in order to change the value, delete the current value with key , enter a new one and accept it with
key . The cassette will return to program A-8.
4. Entering residents’data
(a) If the cassette is installed in place of older KDC1804/1805 cassettes, it is possible to read in the *.CSV file
generated by these cassettes:
•enter program A-6 and select subprogram 5
•enter the file name without extension (the name must consist of digits only) and confirm with button
. The saved file must have .csv extension.
(b) If manual input is required, this can be done in four steps:
•code table setting –these are lock codes generated for the premises 1-255. Default codes are
supplied with the device. If the keyboard is installed in place of the existing system, it is possible
to enter the code table according to previously used one, without the intervention of manufacturer’s
service. In this case, the parameters should be changed in A-8 program: 208 –code table number
and 209 –year of code table
•enter rfid and dallas IDs: program A-1. When the message is displayed the ID should be
applied, then enter the logical number to which the change is to be assigned and accept it by
pressing the key .
•Manual redirection of logical numbers: program A-2. After entering, the cassette will display
message . Enter the logical number and then after displaying enter the physical
target number.
•Change of lock code: program A-3. The operation is analogous to program A-2, the lock code is
assigned to the number entered from the keyboard.

5. Lock settings
By default, the cassette is set to operate with a standard lock with an opening time of 5s. If necessary, its
parameters can be modified. Detailed settings are described in section 7.4.
(a) enter the programming menu ( –>installer code), the cassette should display
(b) enter program A-0 and select subprogram 98
(c) enter a 4-digit number, which shall be composed in sequence:
•number of keyboard for which the lock settings are modified (0 –global setting)
•type of lock (0 –normal, 1 –reversible/jumper)
•bolt voltage in % with respect to supply voltage
For example, entering 0170 will set the reverse lock control to approx. 12V (when supplied with 17V)
(d) accept with key and exit to the main menu by pressing until displayed
6. Adjustment of audio tracks
(a) in program A-8 set the parameter 90. Enter there the time (in minutes), for which the audio adjustment
should be available during conversation
(b) call the property, preferably halfway through the physical length of device line and press any button
(other than that disconnects the call)
(c) adjustment mode is switched with key : when display shows “H”, track parameters without
automatic control are adjusted, and when display shows “A”, autosilencer parameters are adjusted. The
second place on the display indicates which track is being adjusted (dash at the top –track from the
cassette to device, dash at the bottom –track from the device to cassette loudspeaker, the third symbol
indicates the balance adjustment)
(d) with keys 1 and 3 the track is adjusted upwards
(e) with keys 4 and 6 the balance is adjusted
(f) with keys 7 and 9 the track is adjusted downwards
(g) keys 2, 5 and 8 display the currently entered settings of individual tracks
(h) before adjusting the autosilencer, set the balance. In order to adjust the balance, systematically
increase the volume of track downwards and upwards until it is induced. Then adjust the balance to
suppress the inducement. Repeat procedure until the system is stabilized. The next step is to adjust the
volume so that the conversation can be conducted comfortably. The adjustment is carried out in
“manual”mode –letter “H”
(i) switch the adjustment mode to autosilencer adjustment (letter “A”on the display)
(j) adjust the track downwards and upwards with keys as before (without balance adjustment). When the
track is adjusted, the cassette will switch the autosilencer to this track (autosilencer suppresses the
track downwards and strengthens the track upwards in idle state). When the signal is detected on the
track downwards, it switches the gain to this track and simultaneously suppresses the track upwards)
(k) settings are saved automatically, so when the call is finished, they will be entered in the parameters in
A-8 program

7. In case of installation with an additional keyboard (satellite), enter its serial number into the PBX. The
satellite keyboard will be inactive before entering the serial number. Enter the serial number in X001. When a
connection is established between KDC1905 and KDC1915, the satellite display will indicate the idle state by
displaying a dot.
8. For the satellite keyboard, repeat the audio track adjustment.
9. After the residents’data and parameters have been entered, a cassette data backup is required. In order to do
so, enter program A-6, select subprogram 2. After displaying the message , enter the file name
(only digits, without extension) and accept it with key . The cassette will save the data in a form of CSV
file on the memory card.
10. Remove the memory card and save data dropped with A-6 program if necessary to restore the data.

4 System programming
KDC1905 programming methodology is derived from CD1803. The available parameters change and the
organization of parameters has changed in part. The programming menu is divided into 9 subgroups listed in Table
2. Note! Please note that all data (settings, residents list) are saved in the PBX cassette (also satellite settings).
Table 2: Subdivision into subprograms
4.1 Programming mode operation
4.1.1 Entering programming mode
4.1.2 Navigating in the programming mode
4.1.3 Field edition
In order to enter the programming mode, select the key and then enter the programming access code “240361”.
The software version number will be displayed, and then . Enter the installer code (default is “0000”).
The keyboard address will appear on the screen, and then the text will be displayed . The installer code
can be changed from A-7 subprogram level.
After entering the programming mode, the cassette will wait for subprogram number to be entered. Select the
program from the keyboard and accept selection with key . A symbol assigned to a given subprogram should
appear on the display. The cassette response after entering a subprogram is described in Table 3.
Description of individual subprograms can be found further in this manual.
Changing the cassette settings is made by changing the appropriate fields, whether it is a number or the value of
parameter. After entering field editing, the cassette will display the field symbol and entered value, if previously
entered. If the field is empty, the cassette will still display the field symbol.
To enter a new value in an empty field, enter the field, enter the value and accept it with key .

Table 3: Messages when entering the subprogram
4.1.4 Sequential edition fields
Some subprograms, such as A-4 (parameter editing for individual premises), require sequential data entry, i.e. 3
parameters are changed one by one after entering the edition.
Parameter change is carried out as in the normal editing field –after the parameter name is displayed, if a
value is entered, it will be displayed. If the parameter is empty, its symbol will be displayed.
To enter/change an entry, press the button and then enter a new value and accept it with key . The
cassette will then proceed to the edition of next parameter.
To skip changing one of the parameters, it is necessary to use the button instead of button when the
symbol or value is displayed. The cassette will then proceed to edition of the next parameter or, if it is the last
parameter in the series, it will return to the “menu above”.
To change the field value,enter the field, wait until the cassette displays entered value, press key , then
enter the new value and accept with key . To exit the edition without changing parameter, press twice .

4.1.5 Bit masks
Many parameters are set using so-called bit masks. In this way, parameters such as “yes/no”, “on/off”, such as lock
code blocking for the property or selection of locks to be opened when a given event occurs, are saved.
Each bitmask saves up to 8 different options. In this manual, at the description of each parameter, the weights
for a given setting are given. Activation of selected options takes place after summing up their “values”.
Conversions can be carried out bilaterally –in order to read from the value entered in parameter (saved in the
decimal system) which options have been activated, a conversion from the decimal system to the binary system
should be carried out. This can be done, for example, with a calculator (with binary system support).
This notation is natural for digital electronic devices, where the basic unit of information is a bit –0 or 1. Each
bit in the number has its own weight, and the whole number is defined by their sum:
Table 4: Weights (decimal) of individual bits
Examples of such a bit mask are the flags of premises:
“office mode (+1) –if the handset is still raised, each connection to the premises will result in a
simulation of pressing the lock button in hearing aid (it will usually result in the lock opening –depending
on configuration)
“lock code”(+2) –will block the possibility of door opening with the lock code assigned to premises
“mute lock code confirmation”(+4) –after opening the door with lock code, no acoustic confirmation will
be generated in the device (until the blockade was realized by redirecting the logical number to a physical
number that does not exist in the system)
“feedback communication blockade”(+8) –the flag blocks the call from decoder, between the premises
and defined keyboard (supporting Feedback).
“P1 button blockade”(+16) –the flag blocks possibility of door opening with a button in the decoder,
during a conversation
“alternative lock code event”(+32) –the lock code of property will generate an alternative event (you can
change the system function for a given property)
“alternative event for rfid”(+64) –as for the lock code
“forcing impulse addressing”(+128) –enforces addressing of the old type for a single premise, applies to
new installations with bit addressing (parameter 99 and flag +1) and a single “jumper”apparatus
For example, to activate the office mode and block the use of lock code confirmation in the premises you need to
set bits 1 and 3 in the mask saved in parameter 99. Therefore, enter there 1+4 = 5 (according to the weights table).
Bit masks are also used when assigning peripherals to events –for example, opening a lock by pressing the P1
button on the device. In this case, individual bitmasks activate specific transoms after an “event”occurs (the
parameter number defines to which event). For example, the definition of parameter 2361 will be assigned to the
locking systems opened after selecting the P1 button during a keyboard call with address 2 (i.e. the first satellite). As
in the previous case, in this parameter it is necessary to enter the number being the sum of bits set. Entering a value
of 0 results in complete disabling of a given functionality

Table 5: Assignment of bitmask to individual keyboards
Individual bits define which cassettes are to react in case of a particular event. The eighth bit assigns a local
cassette (the cassette from which the connection was made or lock/rfid code was used).
For example, setting bits 1, 4 and 6 (i.e. entering 00101001bin = 41dec) will activate the reaction of cassettes
with appropriate addresses (i.e. PBX and satellites no. 3 and 5)
4.1.6 Exiting the programming menu
To return to the previous menu, select a key . To exit the programming menu, press the button from the main
menu (symbol A-) until the cassette is at idle.
If changes have been made to any of subprograms, the cassette will automatically save data backup to the
microSD card (if installed) at the exit.
4.1.7 Autobackup
Function implemented from firmware version 7r27.
Autobackup function is used to protect data entered into the cassette. The cassette automatically saves data on
the microSD card in the same format as with normal recording (see point 4.7). The recording is called up when
leaving the programming menu (if any changes have been made).
Subsequent backup files have successive names from BAK0.CSV to BAK9.CSV, where BAK0.CSV is the
newest file and BAK9.CSV the oldest.
Reading data from the backup file is possible by program A-6 and function 4 (see section 4.7). The keyboard
will display a message –then enter the number of the file to be read and accept with key . In case
of successful operation, the cassette will signal a message , while an error (usually no file) will be
indicated by a message .

4.2 Subprogram A-1 —entering and deleting RFID and DALLAS IDs
This subprogram, as in case of CD1803 control panel, is used to enter RFID and DALLAS IDs. The IDs are assigned
to entered LOGICAL number (from the PBX’s point of view). Unlike older digital systems, no lock code is required
for the operation of IDs.
After entering the A-l subprogram, the message is displayed . Use the identifier you want to assign
to the property. Then the keypad will display a message alternating with the property to which you
have assigned an ID. If you have not yet assigned an ID, a blinking “0”or the number under which the last ID was
entered will be displayed. To assign an ID to this number, press key . If the ID should belong to another
property, press the button and then enter the number and confirm with button .
In order to delete the ID, place it on the keyboard and when the property number is displayed press
(deleting the assignment) and then confirm it with button .
Deletion of all IDs assigned to one property is possible by program A-0 with parameter 99. Each use of program
A-0 requires verification with the installer code.
4.2.1 Controlled adding of IDs by users
In firmware cassettes from version 7r11 it is possible to add RFID and iButton IDs without the interference of
installer in an existing installation, however under the installer’s supervision. In order to save the new ID in the
system, the user should:
1. at idle, enter the number of premises on the keyboard and press the button
2. bring the ID card close to the reader
3. enter the unique code provided by the installer
If the ID has been saved correctly, the cassette will display “Good”.
Note! For the above procedure to function, parameter number 011 must be different from zero (additional code
securing the addition of IDs).
This unique code for ID verification is generated on the basis of:
•installer code in the cassette
•programming code of IDs (parameter No 011)
•number of the premise
•last 4 digits imprinted on the casing of ID card
The code is generated using a script provided by the manufacturer. Addition of IDs is protected by a separate code
defined in parameter 011. For security reasons, this code should be different from the installer’s code. If this
parameter is not defined, it will not be possible to add IDs in this way.
4.2.2 Open programming of IDs
From version 7r63 onwards, the cassette enables to enter the IDs in Open Learn mode, where users add IDs
themselves, without verification by the installer. The procedure runs in two modes:
•entering IDs to the number specified by the user
•entering all IDs into one property

Parameters used to configure the Open Learn function
•012 –target number for entering IDs. If the value “0”is entered, the ID will be entered under the number
indicated by the user.
•013 –operating time of the Open Programming function in hours.
If the target number (012) is different from “0”, each ID used will be entered into the memory under the number
saved in parameter (Note! –without any authorization)
If the target number is empty, the ID will be entered under the number indicated by the user. In this case, the
addition procedure is as follows:
1. at idle, enter the number of property and press
2. use an ID
3. enter the lock code assigned to the premises used
The Open Programming Time is given in hours. After the set time has passed, the function is deactivated. To
deactivate Open Programming manually, reset parameter 013.
4.3 Subprogram A-2 —forwarding
Subprogram enables manual forwarding of logical number without number conversion settings (e.g. hotel
numbering, pre-shift). The entered physical number must be in the range of 0-255 (in case of cooperation with old
“jumper”decoders), or in the range of 0-16 383 in case of “bit”addressing.
After entering the A-2 subprogram, the cassette will display a message . Enter the logical number to
be forwarded and then, after displaying the message enter the target physical number.
4.3.1 Blocking the number
Using A-2 program it is possible to block the logical number. Blocking the number is made by entering ‘0’as the
target number in program A-2. This results in deactivation of voice connection, and deactivation of access codes and
user IDs.
Unblocking the number takes place after deleting redirection or redirecting to a physical number other than zero.
4.4 Subprogram A-3 —entry of lock codes
The A-3 subprogram is used to enter additional lock codes. When entering the code, a logical number is given (from
the PBX’s point of view), but ultimately the PBX assigns them to physical numbers (after conversion, see point 7.6).
After entering subprogram, the PBX will display a message . Enter the logical number, then the PBX
will display a message and the current lock code assigned to the premises. If no code is assigned, the
default code from the code table is used. The change of entry is analogous to other subprograms. Enter the codes
according to description of editing the sequence fields.
If multiple codes are required for one property, remember that entering any code disables the code table for that
number. Therefore, if one of codes is to be a code from the table, it must be entered manually.
The lock code should be between 4 and 6 characters. Avoid codes starting with “0”.

4.5 Subprogram A-4 —parameters of individual premises
This subprogram enables to change parameters of a given premises (a logical number is used). The available
parameters are listed in Table 6.
Table 6: Options available for individual premises
Table 7: Premises’flags
+32 and +64 flags enable to call other types of events and use other resources, such as locking or OC.
After entering the subprogram, the cassette will successively receive data for the following parameters
. Parameters with symbol are set as flags. In order to set the appropriate configuration
of these parameters, it is necessary to sum up their weights, which are given in Table 7 .

Description of each flag:
•“office mode”(+1) –if the handset is still raised, each connection to the premises will result in a simulation
of pressing the lock button in hearing aid (it will usually result in the lock opening –depending on
configuration)
•“lock code”(+2) –will block the possibility of door opening with the lock code assigned to premises
•“mute lock code confirmation”(+4) –after opening the door with lock code, no acoustic confirmation will
be generated in the device (until the blockade was realized by redirecting the logical number to a physical
number that does not exist in the system)
•“feedback communication blockade”(+8) –the flag blocks the call from decoder, between the premises and
defined keyboard (supporting feedback)
•“P1 button blockade”(+16) –the flag blocks possibility of door opening with a button in the decoder,
during conversation
•“alternative lock code event”(+32) –the lock code of property will generate an alternative event (you can
change the system function for a given property)
•“alternative event for rfid”(+64) –as for the lock code
•“forcing impulse addressing”(+128) –enforces addressing of the old type for a single premise, applies to
new installations with bit addressing (parameter 99 and flag +1) and a single “jumper”apparatus
In order to set the desired configuration for a property it is necessary to sum up the set flags.
Example
In order for the property to work in office mode with lock code blockade, enter value “3”in the field. In order
to block the lock code confirmation, feedback communication and lock opening with the device button, enter
value “28”.

4.6 Subprogram A-5 –special functions
The program contains special functions that are useful for starting up and servicing the installation. After calling the
program, the display will show a text . Enter the service function number and confirm with key.
4.6.1 Function 3 –apparatus testing
It is available in firmware cassette version from 7r13. Entering the function is carried out by entering the program
A-5 and selecting key 3 (function selection).
This function is known from the old type PBX as P3 program. It enables quick verification of decoder
installation by one installer. It consists in automatic addressing of the decoder, after pressing P1 button (principle of
operation as for feedback communication).
Procedure of starting the function:
1. –number of the keyboard to which calls will be forwarded. If 0 is entered, the function is
switched off and there is no access to the next part of configuration. Confirm the entered value with button
2. –logical numbers of devices to be tested. The cassette displays the entry
number and its value alternately. Using the key it is possible to switch between successive entries, and the
entry with the highest number is empty (waiting for a new number to be entered). The list can be dynamically
enlarged and single entries can be deleted.
3. To add a new device number, display the entry with the highest index, enter the new device number and
confirm with .
4. To change the entry, select a key when the number entered under the index is displayed, enter the new
number and confirm with key .
5. Deletion of an entry is possible when the list of numbers is displayed. Display the number to be deleted and
then select the button to clear the entry and then the button to save changes.
6. If the number 0 is entered, the PBX will rely on the number sent by the device (only new devices).
7. Exiting the program is possible after selecting the button twice.
Activated function 3 runs for one hour after the last change of the first parameter of function
. When the tests are finished, disable this function by inserting 0 into the first parameter.
Test procedure for the decoder:
1. Enter the keyboard number to which calls are to be forwarded
2. Enter the physical numbers of devices to be included in the test function
3. Testing will be active for another hour
4. In the decoder, select P1 button with the handset raised. The PBX will address the decoder and after making
a call it will generate a quiet beep in the handset. A call is established –you can test the microphone (the longer
the cable, the bigger the crosstalk to speaker) and the operation of decoder keys.

5. Put the handset down
6. The PBX will establish a connection with the decoder as in case of dialing a number from the keyboard,
which enables to check the ringtone volume and correct operation of the decoder in normal conditions.
7. While testing the decoder, a special message will be displayed on the keyboard
8. After testing all devices, disable the test function
