SD-34 | SD-34.2 English Fire risk Touching flammable material with a hot soldering iron can cause fire, which can result in injury or death through burns or suffocation. Connect your soldering iron or soldering station only when actually needed. Always keep the soldering iron away from inflammable materials.
English SD-34 | SD-34.2 In schools, training centres, clubs and workshops, assembly must be supervised by qualified personnel. In industrial institutions, health and safety regulations applying to electronic work must be adhered to. 3. Safe and correct soldering Caution: Incorrect soldering can cause dangers through fires and heat. Avoid these dangers by reading and following the directions given in the chapter Safety instructions.

(SD-34) or a push-button switch (SD-34.2). When using a Motorola central unit the (accessory) decoder address has to be set with a programming jumper (SD-34) or a push-button switch (SD-34.2). Changing the other decoder´s features or assigning a locomotive address is neither necessary nor possible in layouts run in Motorola format only.

English SD-34 | SD-34.2 Ceramic capacitors Among other things ceramic capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic capacitors are not polarized. Normally they are marked with a three-digit number which indicates the value coded. The number 104 corresponds to the value 100 nF.

SD-34 | SD-34.2 English Light emitting diodes (LEDs) When operated in the forward direction the LEDs light. They are available in several different versions (differing in colour, size, form, luminosity, maximum current, voltage limits). Light emitting diodes should always be connected via a series resistor which limits the current and prevents failure.

English SD-34 | SD-34.2 Opto couplers Opto couplers are ICs, which work similar to laser beam switches. They combine in one housing a light emitting diode and a photo transistor. Their task is the transmission of information without galvanic connection. They are in a DIL-housing with at least 4 pins.

English SD-34 | SD-34.2 7.3. Power supply You can supply the decoder either via the central unit or via a seperate transformer according to the two following diagrams. Power supply via central unit Caution: Switch off the central unit before connecting the decoder.
When using a Motorola central unit you can set the decoder address with a programming jumper (SD-34) or with a programming push- button (SD-34.2). Changing the other decoder´s features or assigning a locomotive address is neither necessary in layouts run in Motorola format only nor possible with Motorola central units.
English SD-34 | SD-34.2 8.1. Programming addresses You can set the decoder address either by programming the CVs with your DCC central unit or by using the programming jumper or push- button. When setting the decoder address it is of no importance if you...
