Here is a connection diagram for the Saxonian IV / k. You can use that diagram also for XL decoder. You can solder the cables simply to the sockets on the PCB. Program CV64=0 and CV54=7. Then the smoke generator is switchable with function key 7. here is the connection diagram for one-engine locos.
You can also connect a XL/XLS Decoder to a Brawa Interface. Therefore you need two 9-pole plug connectors. Connect them like described below. Following special functions of the loco are usable. Light : Swiss illumination (3+1) in both directions. F1 : Light cabin F2 : Shunting lights (3+3) F3 : Smoke unit (CV115=3 parallel output F4 on key 3) Because of the higher amperage of the smoke unit F3+F4 are connected parallel. Alternatively,…
Attached you can find a plan howto connect a L decoder at a LGB interface cable.
If you have old 3-pin Switch-drives from LGB, you can control this with our 4 channel-switching decoders. Here is a sketch how to connect it: The switching time should be set down a little in CV 51-58 (Value 66).
Sorry, this entry is only available in German.
If you would like to control the Uncoupler with the outputs A5-8 from the XL / LS / XLS, you need a small additional circuit for controlling the Uncoupler. See picture with schematic. The circuit can be easily mounted on a stripboard. P.S.: The L decoder does NOT require this circuit!
Attached you can find a small circuit diagram with Schottky diodes, to realize a Swiss Backlight. Complete with switchable red light. The whole works only with LEDs! Licht Schweiz + rot.pdf Here with additional Shunting light: Licht Schweiz + rot+rangierlicht.pdf
With transistors, the function outputs F5-F8 can be operated with a higher current. Here is an example of the XLS. The polarity of a resistor (1KOhm) does not matter. The polarity of the transistor must be observed!
Here is a simple conversion suggestion for the old LGB-2×430 locomotives (Ge 4/4-II) without interface. With an additional 24V relay you can simply use the old pantograph control. The three-pole cable from the lower part to the upper part is removed. The electronics (motor control) in the lower part are replaced by the XL / XLS decoder. The white + brown cable is connected to the decoder via the…
On several occasions, we set up a circuit here to digitize the old DUO locomotives with electric decouplers. The circuit was tested by me once on an XL decoder and worked and is in this form only for one drive usable. Nevertheless, I can give no guarantees for replicas, this is at your own risk. The circuit must be doubled for both drives. The function output of the decoder…
