2.0 Product overview
2.1 General product informaon
The DR4088xx is a feedback module that can be connected to the central unit via the S88(N)®.
The DR4088-xx has 16 feedback inputs.
The DR4088xx is available as CS version (current sensor 2-wire track), as OPTO version (connecon of reed contacts, 3-wire track signal to track ground) and as
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 the S88(N) Bus®:
• The S88(N)® bus is a universal bus system.
• The S88(N)® bus supports a maximum of 256 feedback addresses.
• The addresses are always assigned automacally and connuously. No universal and unique addressing is possible because the S88(N)® bus is not desig-
ned for individual address assignment!
• The S88(N)® can only be set up as a bus (line) network. This always means from 1. feedback to 2. feedback, etc.
3.1 Programming DR4088xx (Assign start address in DR50xx)
The S88(N)® bus system does not provide programming in the actual sense. It only has to be dened in the central with which address the S88(N)® bus starts
and how many modules are located on the bus.
Programming the start address in the DR50xx
1. Start the DR50xx tool.
2. Call up the sengs for the S88(N)® bus with the buon in the ext88N tool.
3. The start address and the number of modules must now be entered in this input mask.

4.0 Connecon examples
In this chapter you will nd some connecon examples for the DR4088xx. Please note that we are not able to show all possibilies.
3.2 Reset DR4088xx
Important! The DR4088xx The DR4088xx has no funcon for reseng to factory sengs!
Since no sengs or funcons are stored in the feedback module, this is not necessary!
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 usu-
ally 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.

DR5000 in conjuncon with S88N® feedback modules
The ext88N connector of the DR5000 is a compable S88N® bus.
In this example the feedback modules DR4088CS (current sensors) are used. These feed-
back modules are connected to the DR5000 and to each other with normal RJ45 cables. A
maximum of 16 S88N® modules with 16 inputs each can be connected to the central unit. A
total of 256 feedback modules (S88N®/ext88N ) can be managed by the DR5000.
