Deleting the filter table
If a device (home station, door station etc.) that functions
across lines is replaced in the door communication system,
or if an already programmed DCS repeater is to be used in
another system, the filter table of the DCS repeater must be
deleted. A backup file must then be implemented or the
complete system must be started up again.
1. Press the "Systemprogr." button on the control device
for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
2. Press and hold the programming button on the DCS
repeater for 6 s to delete the filter table.
✓The LED "Fkt./Prog." briefly flashes green after 3 and 6 s.
✓The LED "Fkt./Prog." lights up green for 3 s:
The filter table has been deleted and terminating
resistance was set to "off".

In door communication systems with video devices,
terminating resistance must be activated on the DCS
Repeaters installed at the end of the line.
1. Press the "Systemprogr." button on the control device
for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
2. Press and hold the programming button on the DCS

A data backup of the DCS repeater configuration can be
generated. This is useful for example when a DCS repeater
has to be replaced due to a device defect. Data backup
should thus be implemented immediately following start-
A microSD card (SDHC) is needed to create a backup of the
DCS repeater. This is contained in the scope of supply of the
DCS repeater. The DCS repeater can also be started up
Files saved on the microSD card should be saved to a
computer and appropriately named (e.g. Repeater1.US)
following the backup process.
Saving data to the microSD card
1. Insert a microSD card into the card slot
2. Press the "Systemprogr." button on the ancillary line
control device for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
3. Press the "Systemprogr." button within 3 s on the
ancillary line control device to exit programming mode.
✓The LED "Fkt./Prog." lights up red:
Data are saved to the microSD card.
✓The LED "Fkt./Prog." lights up green for 3 s:
✓The LED "Fkt./Prog." flashes green 3 times:
Saving failed, microSD card is defective or erroneously
4. Remove the microSD card, save the file to a computer
and name it appropriately.
Copying data from the microSD card to the DCS repeater
1. Rename the backup file to be copied to the DCS
repeater to CFMASTER.TXT on the computer and save it
2. Press the "Systemprogr." button on the control device
for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
3. Press and hold the programming button on the DCS
repeater for 6 s to set the repeater to factory setting and
✓The LED "Fkt./Prog." lights up green for 3 s: DCS repeater
reset to factory setting.
✓LED "Fkt./Prog." flashes 3 times: Resetting failed, please
4. Following successful resetting on the control device,
press the "Systemprogr." button to exit programming
5. Insert the microSD card with backup file into the SD slot.
✓The LED "Fkt./Prog." lights up yellow:
Data are copied to the DCS repeater.
✓The LED "Fkt./Prog." lights up green:
✓The LED "Fkt./Prog." flashes green 3 times:
Copying failed, microSD card defective, erroneously
formatted, or has no data.
Replacing the DCS repeater
If a DCS repeater in a system is to be replaced, it is not
necessary to start-up the complete system again.
Depending on application, the following procedures are
In repeater mode without video function
If a DCS repeater in repeater mode is to be replaced in a
system without video function, no further start-up steps
In repeater mode with video function
If a DCS repeater in repeater mode is to be replaced in a
system with video function, it is sufficient when a call
button is made known to the DCS repeater from each door
1. Press the "Systemprogr." button on the control device
for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
2. Press a call button on the door station for 3 seconds.
Release the call button following the brief
✓The door station outputs a long acknowledgement tone.
3. Press and hold the programming button on the DCS
repeater for 3 s to enter the call button into the filter
table of the DCS repeater.
In multi-conversation mode
If a DCS repeater in multi-conversation mode is replaced, all
call buttons of the door station(s) must be made known to
1. Press the "Systemprogr." button on the control device
for 3 sec. to start programming mode.
✓The LED at the control device flashes yellow.
The LED "Fkt./Prog." on the DCS repeater flashes green.
2. Press and hold the call buttons to be made known for 3 s
at the door station. Release the call button following the
brief acknowledgement tone.
✓The door station outputs a long acknowledgement tone.
3. Press and hold the programming button on the DCS
repeater for 3 s to enter the call button into the filter
table of the DCS repeater.
4. Repeat step 3 until all call buttons are entered into the
filter table of the DCS repeater.
