+ | The higher this resistor will,be, the more signal is received, but that should be limited.\\ | ||
+ | Because all the current going to the rails will pass this resistor, it cannot be too high.\\ | ||
+ | |||
+ | Therefore two diodes (D4 and D5) are in antiparallel connection with the resistor.\\ | ||
+ | They limit the total voltage over this parallel combination to approx 0,5 V in both directions.\\ | ||
+ | That is enough to activate either IC2a or IC2b, and then passed via IC1a or IC2b towards the opto-coupler.\\ | ||
+ | Rocrail will be able with this unit to read back much information from the decoder on the main track, without the need of \\ | ||
