2.0 Product overview
2.1 General product informaon
The DR4088LN-xx is a feedback module that can be connected to the control panel via LocoNet®.
The DR4088LN-xx has 16 feedback inputs.
The DR4088LN-xx is available as CS version (current sensor 2-wire track), OPTO version (connecon of reed contacts, 3-wire track signal to track ground) and
GND version (3-wire track).
2.2 Technical specicaons
The connecon terminals of the 16 feedback units are designed for a cross-secon of 0.5mm², the two terminals for "C" are designed for a cross-secon of
0.75mm².
Important! DR4088GND 3-wire operaon:
Due to the H-bridge (track output) in the DR50xx, feedback devices in the DR4088GND version must not be used against track ground, as
is usually the case with 3-wire tracks. This inevitably leads to the destrucon of the DR50xx.
If a 3-wire driver sll wants to drive with the DR50xx and report back against track ground, the DR4088OPTO
can be used.

3.0 Programming
First, something fundamental about LocoNet®:
• The LocoNet® is a universal bus system.
• The LocoNet® supports a maximum of 2048 feedback addresses.
• The addresses are always stored in the feedback module.
• The LocoNet® can be set up as a tree, star or bus (line) network. A combinaon of the individual topologies is permissible.
• Please note that a ring structure is not permied.
3.1 Programming DR4088LN-xx without further DR4088 on the S88N
DR DR4088LN-xx does not have LNCV's as known from other manufacturers. Therefore no LNCV's can be read out or changed.
The DR4088LN-xx must only be "told" the start address and the number of feedbacks via a switch command!
3.1.1 Programming with the DR5000
1. Connect the DR5000 to the DR4088LN-xx to be programmed.
2. (Normally it is not necessary to disconnect other feedback modules from LocoNet®.
3. Open the DR5000 Tool.
4. First the DR4088LN-xx must be assigned the start address.
5. Open the turnout control panel that contains the desired start address that the DR4088LN-xx is to receive.
6. Press the programming buon on the DR4088LN-xx. The green LED starts ashing to indicate that the DR4088LN-xx is in programming mode.
7. To assign the start address, switch the turnout address e.g. 1 once (i.e. only red or green!).
8. The green LED on the DR4088LN-xx now ashes in a dierent cycle to signal that the DR4088LN-xx next expects the number of feedback signals. The
number of feedback units is again sent to the DR4088LN-xx via a turnout command.
9. Normally, if no DR4088 (S88) is connected to the DR4088LN-xx, this is address 16.
10. In the DR5000 tool, call the turnout control panel which contains the address corresponding to the number of feedback signals.
11. Normally, this is address 16. Again, only red or green switching applies here.
12. The DR4088LN-xx automacally terminates the programming mode and is now programmed with the start address and the number of feedbacks.
.
Important! When using the LN or RB module, the ext88N IN number of 16 and 8 input modules must be set to 0 on the DR5000. This can be checked if in the feedback
monitor row 1 and row 9 are white with blue and not red!

3.1.2 Programming with any control panel or app.
1. Connect the central unit to the DR4088LN-xx to be programmed.
2. (Normally it is not necessary to disconnect other feedback modules from LocoNet®.
3. First the DR4088LN-xx must be assigned the start address.
4. Open the turnout control panel which contains the desired start address which the DR4088LN-xx is to receive.
5. Depending on which control panel, handset controller or app is used for programming, either the corresponding turnout or the corresponding turnout control
panel must be called at the control panel. With some App's a corresponding turnout with the desired address must be created.
6. Press the programming buon on the DR4088LN-xx. The green LED starts ashing to indicate that the DR4088LN-xx is in programming mode.
7. To assign the start address, switch the turnout address e.g. 1 once (i.e. only red or green!).
8. The green LED on the DR4088LN-xx now ashes in a dierent cycle and signals that the DR4088LN-xx next expects the number of feedback signals. The num-
ber of feedbacks is again sent to the DR4088LN-xx via a switch command.
9. Normally, if no DR4088 (S88) is connected to the DR4088LN-xx, this is address 16 .
10. At the central staon, at the handset controller or in the app, call up the turnout control panel which contains the address corresponding to the number of
feedback signals.
11. Normally this is the address 16. Again, only red or green switching applies.
12. The DR4088LN-xx automacally terminates the programming mode and is now programmed with the start address and the number of feedbacks..

3.2 Programming DR4088LN-xx with further DR4088 at the S88(N) connecon
3.2.1 Programming with the DR5000
1. connect the DR5000 to the DR4088LN-xx to be programmed
(normally it is not necessary to disconnect other feedback modules from the LocoNet®)
2. open the DR5000 tool.
3. First, the DR4088LN-xx must be assigned the start address.
Open the turnout control panel that contains the desired start address that the DR4088LN-xx is to receive.
4. Press the programming button on the DR4088LN-xx. The green LED starts flashing to indicate that the DR4088LN-xx is in programming mode.
5. to assign the start address switch the turnout address e.g. 1 once (so only red or green!).
6. The green LED on the DR4088LN-xx now flashes in a different clock pulse to indicate that the DR4088LN-xx is expecting the number of feedbacks next.
The number of feedback signals is again sent to the DR4088LN-xx via a switch command.
Example:
DR4088LN-xx DR4088
Start address 1 Number of feedback units 32 The switch address 32 must be sent here.
DR4088LN-xx 2x DR4088S
tart address 1 Number of feedback units 48 The switch address 48 must be sent here.
R4088LN-xx 3x DR4088
Start address 1 Number of feedback sensors 64 The switch address 64 must be sent here
.etc.
7. In the DR5000 tool, call the turnout control panel containing the address corresponding to the number of feedback signals. Again, only red or green
switching applies.The DR4088LN-xx automatically terminates the programming mode and is now programmed with the start address and the number
of feedbacks.
Aenon! At the S88 connecon of the DR4088LN-xx A maximum of 15 DR4088 can be connected to the S88 connecon of the DR4088LN-xx. This results
in a maximum number of 256 feedback contacts that a DDR4088LN-xx can manage.
Example: DR4088LN-xx 15x DR4088 Start address 1 Occupied feedback device Address range 1 - 256

etc.
6. At the control panel, at the handset controller or in the app, call up the turnout control panel which contains the address corresponding to the number of
feedbacks.
With some App's a corresponding switch with the desired address must be created. Again, only red or green switching applies.
7. The DR4088LN-xx automatically terminates the programming mode and is now programmed with the start address and the number of feedback devices.
Aenon! At the S88 connecon of the DR4088LN-xx A maximum of 15 DR4088 can be connected to the S88 connecon of the DR4088LN-xx. This results

4.0 Connecon examples
In this chapter you will nd some connecon examples for the DR4088LN-xx. Please note that we are not able to show all possibilies that exist.
3.3 Reset DR4088LN-xx
Important! The DR4088LN-xx has no funcon to reset to factory sengs!
The DR4088LN-xx has no funcon for reseng to factory sengs! This is also not necessary because no other funcons can be set in the
DR4088LN-xx except the start address and the number of response addresses.
To reset the response address back to the basic seng 1, it is sucient to send it again to the DR4088 LN-xx as described above. In the second
step, the number of feedbacks must be reset to 16 as described above. Further steps are not necessary.
Important! DR4088LN-GND 3-wire operaon DR4088LN-GND 3-wire operaon:
Due to the H-bridge (track output) in the DR50xx, feedback devices in the DR4088LN-GND version must not be used against track ground, as is

DR5000 in conjuncon with LocoNet® feedback modules (DR4088LN-CS)
In this example the LocoNet® modules DR4088LN-CS (current sensor principle) are used.
These feedback modules are connected to the DR5000 via LocoNet®. A maximum of 128
modules with 16 inputs each can be connected to the LocoNet T socket of the central unit.
A total of 2048 feedback modules are thus possible.
All other connected feedback modules which are connected via ext88N or R-Bus® must be
disconnected from these 2048 feedback modules.
Please note that a DDR4088LN-xx can manage a maximum of 15 DR4088.
