1.1. Contents of the package 1 one kit S88-3 (item no. 44-01305-01), containing the components listed in the parts list (see section 3.4.) and one PCB or 1 ready-built and tested circuit board S88-3 (item no. 44-01306-01) or 1 s88 feedback module S88-3 in housing (item no.
S88-3 1.3. Intended use The s88 feedback module is intended for use in model railway layouts as specified in the instructions. Any other use is not in accordance with the intended use and will result in the loss of the warranty claim. Intended use also includes reading, understanding and following all parts of the instructions.
2. Operation overview The S88-3 feedback module is compatible with all components that work with the s88 bus developed by the Märklin** company. It can read in 16 ground contacts. The S88-3 feedback module is optimised for use in centre conductor systems.
(interface, memory or central unit) or an upstream s88 feedback module. Connection to a downstream s88 feedback module The input of the S88-3, via which the connection to a downstream s88 feedback module is established, is designed as an RJ 45 interface corresponding to S88-N. A patch cable is used for the connection to a downstream s88 feedback module with an s88-N interface at the output.

S88-3 3. Assembling the kit You can skip this section if you have purchased a ready-built module or device. 3.1. Safety instructions Mechanical hazards Cut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB.
S88-3 tams elektronik 3.2. Soldering properly! Use a soldering iron with temperature control, which you set to approx. 300 °C. Only use electronic solder with a flux. Never use soldering water or soldering grease when soldering electronic circuits. These contain an acid that destroys components and conductor paths.

S88-3 Resistance networks In resistance networks there are several resistors integrated. The number of the integrated resistors varies depending on the design. One side of the resistors is commonly taken out of the network, the other side seperately for every resistor.
S88-3 3.4. Assembly Proceed according to the order given in the list below. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter. Follow the instructions on soldering in section 3.2.
S88-3 tams elektronik 3.5. Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: Remove all loose parts, wire ends or drops of solder from the PCB. Remove all sharp wire ends.
Earth connection (if necessary) Connection digital devices and s88 feedback modules The S88-3 has two RJ-45 sockets (IN, OUT) to connect commercial Ethernet patch-cables (RJ- 45 cables), which allow an interference free connection to other feedback modules or digital devices in accordance with the s88-N standard.
